Issued 14th August 2019. After a huge polar low delivered massive amounts of snow over the weekend, negative SAM (Southern Annular Mode) is going to hang in there for another round later this week into next week. A low pressure system south of Tasmania will push a polar airmass northwards over Victoria, the ACT Southern and Central NSW this Sunday & Monday.

VICTORIA: A cold front will sweep East across Victoria with a band of showers on Sunday. Northerly winds could reach 90km hr across Alpine areas and some data suggests Thunder snow is possible on Sunday night with blizzards conditions. 20-30cms of fresh snow is forecast in the 24hrs from Sunday to Monday across the Alps. Snow levels are also forecast to drop to 700 meters across the state so some snow flurries will be possible at Ballarat and Trentham. 

ACT: Showers are forecast to develop on Sunday afternoon and continue overnight possibly into Monday. Showers will falls as snow on the ranges with 10-20cms expected on the peaks. Some brief snow flurries will be possible in Canberra early Monday morning. 

NSW: The cold front moves East across the interior on Sunday with strong cold Westerly winds developing through the Western half of the state. A band of showers and isolated storms are forecast across Southern areas which will eventually reach the Central Tablelands Sunday night. The coldest airmass arrives late Sunday night and hangs around until Midday Monday so snow will be possible on the CTs during this time. AT this stage the snow producing cold air and precipitation does NOT reach the Northern Tablelands. 

For SA the front moves through on Sunday with showers and isolated storms across the South East. In Tasmania the front moves through on Sunday and Monday with showers across the state and snow to low levels on Monday. Below image snow accumulation forecast totals via Windy.com
