Winter is about to turn itself up a notch over NSW, VIC and the ACT with frigid temperatures – even for Winter standards!

Its been cool and cold in some areas up until now with the start of the event, but across Friday, the weekend and into early next week – temperatures are about to plummet in a big way with most areas seeing their coldest temperatures of Winter so far. This is all being brought on by the combination of a very cold, polar airmass moving directly over the region, showers / rain periods and snow and strong to damaging gales that will likely remain constant across the entire outlook period of Friday to early Monday.

The coldest temperatures of course will be across the Snowy Mountains. Thredbo is going for a maximum of -5ºc (yes minus) across Friday and Saturday with Sunday being fractionally warmer at -3ºc. Minimums for the area will be around -7ºc and the wind chill could be closer to -20ºc! Mount Hotham in VIC is also looking at minimum of -7 or -8ºc with maximums of -4ºc. 

Further North, Canberra is expected to only reach 8ºc across Friday, Saturday and 10ºc Sunday – even these temperatures may be a struggle to reach if precipitation remains constant. Overnight minimums of 1ºc or less will mean that snow is possible each night as long as there is precip. Melbourne is expected to struggle to double digits across the 3 main days as well. Ballarat may only get to around 6 or 7ºc as well on Friday and Saturday. 

 

Further North again, the Central Tablelands will mimic what the normal Snowy Mountains are like. Oberon is going for just 2ºc as a max on Saturday and 3ºc on Sunday – roughly 8-9ºc below average. Bathurst will struggle to 6ºc. Orange is only expecting to reach 3ºc on Saturday and Sunday (8ºc below average). On Sunday, Guyra is heading for just 4ºc as a max, Glen Innes and Armidale a freezing 6ºc – this is around 8-9ºc below average. Even across the Central Coast – Sydney and Newcastle are only heading for the mid-teens which is below average for Winter standards. 

Widespread strong to damaging winds of 70-100km/h will make conditions feel even colder with many areas looking at sub-zero degree feels like temperatures.
