An Antarctic explosion is set to hit several states, plummeting temperatures and threatening a winter snow discharge not seen in two decades.
A polar explosion will hit Australia on Sunday bringing freezing weather just in time for the seasonal switch to winter.
Some parts of the country are set to experience the lowest temperatures of the year, as a cocktail of winter weather conditions brings rain, hail, wind and snow.
Meteorological zone meteorologist Joel Pippard said an Antarctic air mass invading Australia on Thursday and Friday would collide with two sources of moisture as it pushes north towards South Australia on Saturday.
“The first is off the northwestern shelf of Western Australia with a subtropical low and the second source of moisture is a large Tasman Low that appears to be forming over the next few days,” Pippad said.
“Setting Antarctic cold air with humidity can be very conducive to heavy, low-level snow.”
There is a high probability that snow will fall on NSW and the Victorian Alps and Tasmania highlands as early as Sunday.
“May the snow usually doesn’t stop until the season opens in June,” Pippard said.
“The exception is when it snows heavily towards the end of May, as it could happen next Monday and Tuesday.”
This happened during the famous May Blizzard of 20000 which turned an NRL game in Canberra to white and kicked off an incredible snow season.
Southern Western Australia felt the chill on Saturday, as parts of the southern cast were hit by heavy rain, gusts of wind and thunderstorms.
More rain is forecast for the northwest and coast of Pilbara until Sunday with forecasts of up to 90mm and total blocks of 120mm in some parts.
SOUTH OF AUSTRALIA
The Bureau of Meteorology has a severe weather alert for the southern state in place until Sunday, as damaging gusts of wind hit the region.
Adelaide is expected to reach lows of 9 ° C in the early hours of Sunday morning, as many parts of the state have experienced the coldest day of the year so far.
Intense rains and thunderstorms will last until the beginning of the week.
Victoria will hold out until Monday and Tuesday before gusty showers, strong winds and possible storms hit the state.
Melbourne will see temperatures drop to 7 ° C on Monday, with a low of 6 ° C forecast for Bairnsdale in the western part of the state.
Alpine blizzards are very likely to bring another discharge of snow over the mountainous regions on Tuesday.
Heavy thunderstorms and damaging wind warnings with the possibility of hail are expected for the beginning of next week.
NEW SOUTH WALES
Early next week, a frigid front carrying rainfall and gale force winds is on its way into the interior of New South Wales.
A severe weather warning has been issued by the BOM for the winter blast that will focus on the west as well as the central and southern ranges.
“Snow is expected in the Alpine region, with the possibility of snow around the highest parts of the mountain ranges outside the Alpine region extending to the central plateau,” a BOM spokesperson said.
The east coast will be hit by strong winds Monday and through Tuesday.
Colder temperatures won’t hit the capital until Thursday, when parts of the state’s midwest, including Dubbo, Coolah, and Mudgee, wake up to -1 ° C.
Lithgow, Orange, Bathurst and Crookwell will drop to -2 ° C on Thursday morning, while the coldest part of the state will be Armidale, in the Northern Tablelands it will reach -3 ° C.
Thursday will also be the coldest so far for Queensland as morning temperatures in the south only reached 1 ° C in Stanthorpe and Applethorpe.
The capital Brisbane will hit a low of 6 ° C on Thursday morning.
The polar blast will arrive in the southern state with a bang on Tuesday, as snow is expected to fall as high as 700 meters.
Freezing temperatures and potentially damaging winds are expected for the start of the week, with the possibility of hail and thunderstorms.
