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.
