Space Station Visible Over Brisbane, Sydney, Canberra, Melbourne!

Issued for Thursday 17th May 2018. Be sure to look up in the sky on Thursday night shortly after sunset and show the kids! The ISS or International Space Station will make a visible pass directly over South East Australia for 6 minutes at each location. Above image via ISS astroviewer.

The following times are for South East QLD and North East NSW districts. Beginning at 5:48pm this the ISS will start to be seen in the South West sky while heading towards the North East. At 5:52pm it will be passing directly over North East NSW. By 5:55pm it will vanish again off in a North East direction over the Coral Sea.
Sydney and Canberra beginning at 5:47pm this the ISS will start to be seen in the South West sky while heading towards the North East. At 5:50pm it will be passing directly over Central inland NSW. By 5:53pm it will vanish again off in a North East direction.
Melbourne 
begins at 5:45pm and the ISS will start to be seen in the South West sky while heading towards the North East. At 5:48pm it will be passing directly over Central Victoria. By 5:52pm it will vanish again off in a North East direction.

South East AUS Low – Rolling Updates, May 2018

FINAL UPDATE 10am 13/5/18 – ALL SEVERE WEATHER WARNINGS FROM THE SYSTEM HAVE NOW BEEN CANCELLED.

The deep low pressure system is located well off the NSW coast though is it still causing some strong winds and showers to the Central NSW coast. The low is forecast to move South East towards New Zealand during Sunday and Monday with showers being maintained along the NSW coast. This severe weather system has delivered widespread rain to South East Aust (some record breaking rain and flooding in South East Tasmania), damaging and destructive winds from 90 to 135km hr across large parts of South East Aust, large dangerous surf, very cold temperatures, snow to low levels in Victoria, snow on the NSW Central Tablelands with blizzards on the Alps.
We hope everyone has remained safe during this unusual May weather pattern. Our thoughts are with those who suffered damage and losses in South East Tasmania due to severe flooding. Thank you for following Higgins Storm Chasing we hope you have valued our accurate forecasts, warning, updates and coverage of the system. For a full run down of the Super Low please read our detailed blog below.

SOUTHEASTAUSTLOWBOMSAT13THMAY2018


UPDATE: 6:10PM 12/5/18 The low is now centred around 480km East of Sydney and moving away from the Coast. Scattered showers and light to moderate rain areas are continuing across the NSW South and Central Coastal areas with Merimbula on the NSW South Coast leading all on 27mm since 9am. Strong to damaging winds of 75km/h+ are still lashing the NSW South Coast. Conditions have improved across nearly the entirety of VIC now, however damaging winds and very cold temperatures are still being observed across the Alpine areas.


UPDATE: 1pm 12/5/18  Some big wind gusts have been observed over the Snowy Mountains and Alps in the past 12-18hrs as the Low rips damaging Southerly winds up the NSW Coast and across Eastern VIC.

• Mount Hotham 143km/h (twice) (gusts to over 120km/h for 11hrs straight)
• Falls Creek 130km/h

• Mount William 122km/h (yesterday)
• Montague Island 115km/h
• Green Cape 113km/h
• Mount Ginini 113km/h
• Thredbo 111km/h
• Mount Buller 106km/h
• Cape Otway 100km/h
• Gabo Island 100km/h

These kinds of winds were no doubt creating blizzard conditions across the peaks of the Snowy Mountains and Victorian Alps overnight. While good falls of 50-100mm have been observed over Eastern VIC as forecast. Further good falls today should push totals above the 100mm for a few locations as forecast for the event.

UPDATE: 8:30am 12/5/18  The centre of the low which has been the cause of all the severe weather over TAS is now located about 250km East of Wollongong on the NSW Illawarra Coast. The system is continuing to move in a general North to North East direction and allowing rain areas to stream along the NSW Coast South of Sydney. Some pockets of moderate falls are occurring and this has lead to isolated falls of 25-40mm being recorded so far. The swell is expected to increase across this morning as the strong winds continue to lash the Coast.

UPDATE: 9pm 11/5/18  Rain areas are easing across the Eastern half of Victoria. These rain areas are expected to continue throughout the night across Eastern VIC where locally heavy falls are possible. The centre of the dominating surface low is situated well East of Bass Strait over the open Tasman Sea waters and is expected to move slowly North leading to an increased swell across the NSW South and Central Coast’s as well as Eastern Coastal parts of VIC during the night and into tomorrow morning. Rain is still falling as snow over Alpine areas such as the Victoria Alps and Snowy Mountains, while flurries cant be ruled out over the highest peaks of the Central Tablelands.


UPDATE: 6pm 11/5/18  Rain areas are continuing across Central and Eastern VIC with good falls of 10-25mm so far along with scattered falls North and East of Greater Melbourne of 25mm+ and isolated falls of up to 50mm since 9am. Rain is continuing to fall as snow across the Alpine regions with some scattered showers pushing in over Southern and Central Inland NSW. Temperatures are remaining freezing across both Victoria and Southern NSW. Canberra has recorded its coldest day this early in the year since 1970, registering a maximum temperature of just 9.0ºc. Bathurst could only warm to 7.2ºc, Orange 5.9ºc. Mount Hotham couldn’t even warm above freezing with -0.4ºc so far today as a maximum while Thredbo’s -2.2ºc max so far is the coldest for the year, the wind chill has been brutal with it feeling colder than -10ºc all day.

UPDATE: 12pm 11/5/18 The current satellite image from BOM below shows the deep low between North East Tasmania and South East Victoria. The system is forecast to move North East offshore from the NSW during Saturday before moving South East and away on Sunday. Rain areas are continuing across Central Victoria including Melbourne and the North East quarter of Tasmania. Heavy rain and flooding has now eased from the Hobart area and is not forecast to return. Snow is continuing to fall across Alpine regions and high elevations above 900 meters in Central / Southern NSW including the ACT. Scattered showers and strong winds are continuing across Adelaide. Strong winds are remaining in place for the next 24 hrs across SA, VIC, NSW, ACT and Tasmania with fresh cool South West winds now also extending across most of QLD. Heavy rain is still expected to develop across far Eastern VIC and far Eastern NSW during Friday night into Saturday morning. Strong Southerly winds will extend along much of the NSW coast on Saturday. 
BOMSAT11THMAY2018


UPDATE: As of 9am 11/5/18, Melbourne City had recorded a daily maximum (from 9am Thursday to 9am Friday) of just 12.8ºc, this is the coldest temperature for Melbourne this early in the year since 1970!


UPDATE: 6:35am 11/5/18 rain areas had eased across Tasmania with scattered showers persisting out of the South East now. These showers were allowing rainfall totals to continue accumulating with Mt Wellington up to a staggering 224mm and Grove 156mm – both all time new daily records for ANY month. Hobart was sitting on 128mm which was nearly 3x the previous May record and 4th wettest day in history. Snow was also being reported as settling across the NSW Central Tablelands with new reports overnight out of Oberon and Blayney.

UPDATE: 12:25am 11/5/18  Severe thunderstorms have eased across the Hobart region however continued heavy rain is still occurring. The City (Hobart) has officially surpassed 100mm since 9am, making it the first time ever in May this has occurred and only the 5th time in history for Hobart City. Mt Wellington is pushing towards 150mm since 9am and almost doubled the previous May record. Major and rapid flash flooding was being observed across Hobart leading to several cars being washed away and streets turning into rivers. Power remained out to at least 10,000 people possibly more with rain areas still impacting the region.

UPDATE: 11:20pm 10/5/18 Severe thunderstorms were lashing South Eastern parts of Tasmania including Greater Hobart. Heavy rain in the vicinity of 60mm in an hour had been recorded over Mt Wellington and 44mm in 1 hour at Hobart. Totals since 9am had exceeded 94mm in Hobart and 136mm at Wellington – both obliterating the previous May daily record. Extensive and rapid flash flooding had been observed across the City of Hobart leading to several car incidents along with more than 15,000 people without power.

Across the VIC Alps and Snowy Mountains, heavy snow was continued to be observed with Thredbo sitting on a nation low of -5ºc with wind chill making it feel closer to -14ºc. Falls Creek has brought out the snow plows to clear some of the snow already. While the Brindabella Ranges in the ACT were white from snow. Snow flurries were starting to be observed over the NSW Central Tablelands at Arkell (near Blayney) with flurries likely occurring around the Jenolan Caves and Oberon.

UPDATE: 10:15pm 10/5/18 Hobart on 56.8mm has just broken the 136 year May daily rainfall record as heavy thunderstorms impact the city. The 177 year rainfall record at the Botanical Gardens site is also very likely to be broken tonight. A convergence line is feeding in from the East with further heavy falls expected for most of tonight, the city may even reach 100mm by morning! Heavy snow is impacted the Great Lakes with power surges (see video below). We had forecast this record potential earlier today HERE


UPDATE: 9pm 10/5/18 Winds and rain increasing further across South East Tasmania with the deep low circulation near the East Coast. Maria Island has recorded 81mm to 9pm which has set a new May daily rainfall record surpassing 77mm in 2012. Hobart is over halfway to setting a new May daily rainfall record with 27mm so far. Damaging winds of 89km hr at Hobart airport and a whopping 132km hr at Mt Wellington. Heavy snow is falling across the Central highlands. Blizzard conditions now impacting the Alps with 87km hr winds and heavy snow falling. Snow has also been recorded at Mt Beauty in Victoria which is at just 366 meters! Orange in NSW is now down to 1C with snow showers coming in from the west. Damaging winds to 100km hr have been observed along the South Australia South East Coast.

 UPDATE: 5:30pm 10/5/18 Very cold temperatures of 10C or below and feels like temps of 5c or below being oberseved across all of Victoria, Southern inland NSW, ACT, South East SA and Tasmania. A band of rain is heading towards the Brindabella Ranges in NSW/ACT which is likley to produce overnight snow due to -2C temperatures. The same band of rain is likely to cause heavy snow across the Alps tonight. Rainfall is increasing across Eastern Tasmania with some offshore thunderstorms observed. Winds increasing across South East Tasmania with Hobart recording 80km hr and Mt Wellington recording 104km hr. Some storms have developed just offshore near Newcastle and Southern NSW these are moving away from the coast. 
BOMSAT10THMAY2018


UPDATE: 3:30pm 10/5/18  The upper low cold pool of air is now positioned firmly over Victoria and Southern NSW moving North to North East, there are two low level circulations one in Bass Straight and one North East of Hobart. The system is producing scattered showers across VIC, some briefly moderate and some that may contain small hail. Snow is falling across the VIC Alps and may fall over the Dandenong Ranges over the next few hours if it hasn’t started already. Snow is being reported from the Great Lakes in Tasmania. 

We have already seen good snowfall being reported across the Victorian Alpine resorts and Snowy Mountains with several locations, mostly over the South West of VIC reporting small hail with showers earlier in the day. As of 3:30pm, mostly light falls had occurred across VIC although falls of 25-40mm have been observed across South East and Eastern Tasmania as a result of a Tasman Low impacting the region over the course of today. Damaging winds have so far been observed only briefly over elevated parts of Tasmania and Victoria.

Sydney endures hottest April on record

April 2018 has been anything but a typical April for Greater Sydney as it has endured its hottest April on record and driest in 12 years! Thankfully times are changing and it looks like May could return back to a somewhat normal perspective. Above image via BOM –  Rainfall anomaly for April for NSW showing well below average for Sydney.

 

 

Greater Sydney, particularly those along the Coastline that typically see cooler weather for the localised region, has just experienced its hottest April on record. Sydney’s records date back to 1859 and April 2018 has defied the typical April consensus to shatter heat records. Sydney City for April has recorded an average maximum temperature of 26.1ºc – this is not only 3.6ºc above the long term average of 22.5ºc, but also higher than the January average of 26.0ºc. So essentially, it was as hot as Summer. The high temperatures weren’t missed either, with the 34.2ºc daily record set in 2016 for April surpassed twice with 35.4ºc on the 9th and then 34.6ºc on the 12th. Both of these scorchers were part of a long run of 17 straight days above average to start the month. The average maximum temperature from April 1 to 16 was 28.4ºc (a staggering 5.93ºc above average). 

Not only were the maximums ridiculously warmer than normal… the minimums were just as abnormal with a record breaking 18.0ºc average for Sydney City. It took until Sunday morning (April 29th) for the first below average morning to occur. The Western Suburbs weren’t as drastic, but Penrith recorded its hottest April in 21 years and Richmond 23 years.

The above average heat was also combined with well below average rainfall. Penrith recorded less than 1mm for the month, Blacktown less than 6mm, Richmond less than 10mm and Sydney was a measly 23.4mm. This is only 18% of the normal April average of 128mm, the first time since 2010 that less than 100mm has occurred in April and the lowest monthly total since 2006. 

 

Rainfall deciles for NSW across April. Greater Sydney is showing very much below average.

Thankfully it looks like the atmosphere is already responding to a change, with the only 5 rain days for Sydney occurring over the last 5 days (April 1 to 25 recorded 0.0mm) and an obvious change in temperatures with back to back below average nights and 2 of the last 4 days below average also.

2017-18 Tropical Cyclone Season Summary & Review

Published 25th April 2018. Well the 2017-18 Tropical Cyclone Season has officially come to an end across the Australian area of responsibility with numbers eventually nearing the expectations set out back in October ahead of the season. Above image Cyclone Marcus at maximum intensity. 

 

 

The prediction issued back in October 2017, was for a near normal number of tropical cyclones across Australian waters during the 2017-18 season, to be precise it was a prediction of 11. For the 2017-18 season we saw 10 tropical cyclones across our waters with the bulk of activity occurring over the Indian Ocean before a late by underwhelming burst occurred in March over the Coral Sea. Overall we had expectations of up to 5 severe tropical cyclone which exceeded the reality of 2 which occurred while a total of 5 landfalls were expected when in reality, 6 occurred.

The Indian Ocean was favoured for the season due to abnormally warmer temperatures along with an active MJO and Monsoon Phase occurring over the region for extensive periods of time. Ridging patterns also favoured any systems in the North moving South West and towards the WA region. There were several low’s trying to spin up over the Coral Sea, but the main hindering factor was increased vertical wind shear which didn’t allow the convection to develop for these low’s to transition into cyclones. The below-expected number of severe cyclones is largely due to where the systems developed. Most systems were developing over the Arafura Sea and near the WA Kimberley Coast which meant land interaction halted the intensification process.

So how did the season pan out?

It was an early burst of activity which got the season going as 2 tropical cyclones (Cempaka and Dahlia) developed near Indonesia and ventured “just” into our waters. The 2 systems failed to become much as they intertwined with each other and left Dahlia as the dominant system. There was a lull then until just after Christmas when Cyclone Hilda developed into a Category 2 system and made landfall South of Broome at Anna Plains on December 28. The New Year started quickly with Cyclone Irving developing in the Indian Ocean and impacting nobody, before Cyclone Joyce developed briefly off the WA Coast and made landfall over the Northern Pilbara.

It wasn’t until almost 6 weeks later that the cyclone season resumed as Cyclone Kelvin developed as a tropical low North of the NT and tracked South West where it became a named system before making landfall South of Broome again. It took until Mid March for QLD to see its first activity as Linda developed over the Coral Sea and tracked South.. at the same time, the strongest system of the system Marcus was causing havoc as he made landfall over Darwin as a Category 2 and then bombed into a strong Category 5 system over the Indian Ocean and reached strong enough parameters to be in the top 10 strongest cyclones of all time in Australian waters. While Marcus was doing his thing, Nora developed in the Gulf of Carpentaria and made a bee-line for the QLD Peninsula where she made landfall as a Category 3 system. Then how could we forget the final system… Iris. The system that circumnavigated the Coral Sea over the course of a 3 week (21 or 22 day) stretch and ended up impacting basically nobody.

A further 13 tropical low’s developed which didn’t reach cyclone thresholds. The most notable was Tropical Low 11U which meandered around the Northern WA region for quite a while, delivering near record-breaking rainfall cross the Broome region. A combination of some transient lows and tropical lows also produced heavy rainfall across February and March though Tropical North QLD with some places recording more than 3000mm in the space of 6 weeks.

Thankfully despite a near-normal season, the damage and death toll was minimal. Nobody died in Australia (41 deaths occurred from Cempaka over the Java region however) with only $42M in damage ($26M from Macus and $16M from Kelvin).

While we cant rule out an out of season May tropical cyclone given how warm the sea surface temperatures still are across the region, the official end to the season itself has come.

Brief Warm Period for SEQLD Before Temps Cool Down

After a brief taste of what Autumn should be like, temperatures are expected to warm back up again across South East QLD before cooling down over the weekend. Above image – Maximums for Thursday via BSCH.

 

 

Over the past week, temperatures have been pretty normal for April across South East QLD with Brisbane averaging 26.7ºc (just below the April average of 27.1ºc) and Ipswich sitting right on its April average of 27.2ºc. This is about to change through as a surface trough becomes positioned a little off the Coast and allows the winds to draw in some extra warmth temporarily. This should lead to maximums on Wednesday becoming slightly above average by about 1-2ºc and then further on Thursday by a few degrees more as maximums potentially push the 30-31ºc mark in some areas. Its essentially expected to be the best of both worlds, as the daytime maximums heat up, clear skies should keep minimums to slightly below average for this time of year (sitting around the low to mid teens depending on your exact location). 

 

 

This as stated above though is just temporary. During the weekend, a fresh South to South East breeze is expected to dominate once again and draw in much cooler conditions over the region. The majority of South East QLD is expected to sit around the 24-25ºc during Saturday and Sunday which is 2-3ºc below average for April. Along the Ranges, the temperature may even struggle to exceed 20ºc at Stanthorpe. Night time minimums should remain similar and sitting around 1-2ºc below average also. There is the addition of some very isolated showers becoming possible over parts of South East QLD and the Wide Bay Coast (not all areas though). If any showers were to occur, they should drop the temperature briefly and produce nothing more than a few mm at best.

Another very warm April day in SA

Issued 23rd April 2018. Yet another very warm to hot day well above average temperatures is expected across South Australia today. Above image via BSCH.

A surface trough will drag very warm to hot North West winds down across the state on Monday. Maximum temperatures are forecast to be up to 10C above the April average across the state. Adelaide is headed for a top temp of 31C while further inland widespread temps between 33 to 35C are expected.

A cooler change will push East across the Western half of the state during the afternoon producing some showers and storms. The change is forecast to reach Adelaide at around 5pm. 

During Tuesday the cooler Southerly winds will spread through the Southern half of the state but temps will remain high through the North East. Some showers and isolated storms are forecast across the Southern half due to the trough. Adelaide will cool to 26C on Tuesday then 21C on Wednesday. 

17 04, 2018

Cooler Wet Weather For SEQLD

Issued 17th April 2018. After a run of above average temperatures and clear blue skies, Queensland’s South East Coast is expected to end the week with cooler wet weather. Above image 5 day rainfall forecast totals via Windy.com Green = 10 – 25mm, Brown = 5 – 10mm.

A very warm day is expected today with Brisbane and Ipswich headed for a top of 31C, the Gold and Sunshine Coasts won’t be far behind on 30C. During the afternoon a South East wind change is forecast to develop with gusts up to 45km  hour along the coast. 

On Wednesday winds turn more deeper onshore from the South East dragging in additional moisture while an Upper Trough of cold air moves overhead causing instability. Scattered afternoon showers and the slight chance of an inland storm are likely to develop across the South East Coast. Falls to 9am Thursday of between 10 to 20mm are forecast along the coast decreasing to around 5mm inland along the Great Dividing Range. Maximum temperatures will drop by up to 5C compared on previous days with tops around 27C.

During Thursday scattered showers are likely to continue across the South East Coast due to the onshore wind flow along with the chance of a few inland storms during the afternoon. 24 hour totals up to 15mm are expected along with continued cooler maximum temperatures of 26C.
A stronger trough moves through Southern inland QLD across the Warrego and Maranoa which is likely to produce scattered showers and storms during the afternoon. Some of this activity could push East onto the Darling Downs during the evening.

For Friday the instability increases further across most of the South East due to a new Upper Trough of cold air which is likely to result in further showers along the coast with showers and storms through South East and Southern inland districts. 

Across the weekend unstable conditions are forecast to remain in place with further showers and isolated storms likely across the South East quarter of the state.

Snow Tease to hit Tasmania and the Snowy’s this weekend

South Eastern AUS is expected to experience its first proper snow for the season as a pool of freezing air moves over the region this weekend. Above image – Forecast snowfall across Tasmania this weekend via Windy.

 

South Eastern AUS is expected to be impacted by widespread severe weather this weekend (Saturday and Sunday) as a vigorous cold front brings damaging to destructive winds across Tasmania, Victoria, elevated parts of Southern NSW and South Eastern SA along with thunderstorms and good rainfall to some areas. There is also an added risk of some half decent snowfall across the Tasmania Highlands and Snowy Mountains as a tongue of very cold, freezing air extends up from Antarctica behind the cold front as it moves through. This will drop temperatures to below 0ºc over Tasmania at 1500m ASL and near 0ºc over the Victoria just above 1500m ASL.

Temperatures at 1500m ASL (not surface) over South East AUS on Sunday morning via Windy.

Temperatures at 1500m ASL (not surface) over South East AUS on Sunday morning via Windy.

 

Moisture should combine with the cold air to produce snowfall down to around 800m across Tasmania, possibly even 700m with falls of up to 30cm forecast over the Tasmanian Highlands. Lighter falls of up to 10-15cm are expected over Thredbo and 5-10cm over the VIC Alpine due to the slightly warmer temperatures. The potential for damaging to destructive winds will also increase the risk of blizzards across the TAS Highlands and peaks of the Snowy Mountains. The best timing for the snow is expected to be late Saturday and until around mid morning. The cold air whilst it isn’t expected to bring snow to other areas, it could also result in some hail showers and an increased risk of hail with any storms that occur – mainly across TAS and Southern VIC.

 

Its not uncommon to see Tasmania receiving a good snow dump this early on in the season (which technically is yet to start), but it is encouraging for snow lovers and winter lovers that we are only a tease away from being in the cold season.

Widespread Severe Weather to sweep SE AUS this weekend!

A strong low and cold front is expected to cross the Bight bringing destructive winds to VIC and huge waves to SA! Above image via Windy showing rainfall (yellow >50mm, red >100mm).

 

 

A strong low pressure system linked to a cold front is expected to cross into the Eastern Bight tomorrow (Saturday) and move towards Tasmania. This low is expected to have a very strong and deep onshore wrap which is likely to feed up over the Bight and wrap around the Northern side of the low over South Australia and Victoria. The most prominent feature of the system is going to be the widespread damaging winds across South Australia, Tasmania and virtually the entirety of Victoria. Furthermore, destructive winds of more than 125km/h are expected across the Snowy Mountains – mostly during the afternoon and overnight into Sunday. This system should also bring enhanced showers, some possible thunderstorms and hail to Victoria and Tasmania throughout the day. Any storms that do develop are likely to contain stronger (damaging) winds and small hail. Snow cant be ruled out either for the Alps, but only as flurries on the absolute peaks of the Snowys and Tasmanian Highlands.

The other feature is the huge swell across the Bight! Some fairly big waves are expected for South Australia which is usually protected from the monster waves that Australia sees (unlike the South West WA Coast and Tasmania). Waves should start at 3-5m in the morning and could increase to as much as 8-10m by the afternoon. These waves should eventually also impact Bass Strait and Tasmania overnight Saturday into Sunday and then throughout Sunday as the low moves into the Tasman Sea.

Warmest April Heat since 2006 for SEQLD & NENSW

Temperatures are expected to be on a noticeable climb across SEQLD and NENSW across the weekend and Monday, to end the Easter school holidays across the region. Above image: Maximums for Sunday via BSCH.

 

 

The system which produced record breaking heat across South Australia, New South Wales and Northern VIC is now expected to finally approach North East NSW and South East QLD, and while the temperatures experienced aren’t expected to be record breaking by any stretch… they are expected to be well above the April norm and could produce the warmest temperatures for April since 2006.

The heat will build up slightly on Saturday with maximums into the low 30’s across SEQLD and NENSW, particularly over places like Ipswich and Gatton which could see 32 or 33ºc, Brisbane City and places like Lismore, Casino, Beaudesert, Gympie are heading for around 30ºc. On Sunday, a trough is expected to near the Coast and direct hotter, drier air across the region resulting in temperatures climbing around 4ºc. This will allow Brisbane and Ipswich to reach 34ºc, Gatton potentially 35ºc. If this was to occur, it’ll be the warmest April day since 2006 (33.7ºc in Brisbane, 35.5ºc in Ipswich).

The heat should then ease a degree or 2 on Monday as the trough tracks back Inland a fraction and allows for an increase in humidity. So while it could be a degree or 2 cooler (around 31-33ºc for most areas), the humidity may make it feel slightly warmer than previous days. This will lead to Brisbane recording at least 3, maybe 4 straight days above 30ºc for the first time since 2002 when the City went on a run of 6 days above 31ºc. A return of showers and the addition of some possible storms are expected to break the run of 30ºc+ heat next week.
