Canberra make sure you rug up, and prepare to get the credit card out to scrape the frost off your windshields.
The territory is expecting a dusting of snow on the Brindabella Mountains as temperatures plummet to a low of minus 7 over the weekend.
"We're expecting a pretty chilly one," said Bureau of Meteorology forecaster Rosemary Barr.
"A cold front will be moving across the state late on Friday and there'll be a high pressure system behind that."
While Friday and Saturday will see relatively modest overnight lows of minus 1, come Sunday things will be much frostier. A low of minus 7 is forecast for Canberra ahead of a top of just 10 degrees.
"It might be closer to minus 6.5 in the end, not that that will make much difference," Ms Barr said.
Friday will see rain and a top of 12 degrees, and Saturday is shaping up to be a sunny 11 degree day.
Conditions don't look overly pleasant for the first week back at school either, with the chance of bursting showers and strong winds up to 50kph.
Afternoons are expected to reach average temperatures of around 13-14 degrees from Monday through to Wednesday and there's snow on the cards for the Brindabella Mountains as well.
Ms Barr said the weekend's cold weather comes off the back of a unusually dry June that kept daytime temperatures relatively average but saw overnight lows plummet.
"Overnight temperatures were quite cold, almost unseasonably so," she said.
While the lowest July temperature on record was minus 10 in 1971, Canberrans shivered through minus 8.7 degrees earlier this month.
"It was very unusual," Ms Barr said.
Out on the horse track early Wednesday morning, in a paddock full of frost looking over a picturesque Thoroughbred Park, trainers and horses alike struggled against sub-zero temperatures.
Lead trainer Adam Ayre said that local horses generally acclimatise to the colder conditions better than the interstate horses.
"The horses that are bred in Canberra are used to the colder conditions, but the horse's interstate struggle a little bit with it and are reluctant to come out at first, then overtime they get used to it," he said.
Mr Ayre said work could be a bit slow on cold, winter mornings.
"Wearing extra layers doesn't make it go quicker. Some of the time were just waiting for things to defrost before commencing work."
Fog could also create an issue, at times shutting down the track for the morning.
"If the supervisor says that he can't see anything beyond 200m, the track will be closed for a short period of time because training can become quite dangerous for everyone," Mr Ayre said.
