From alpine snow, to a frosty start to the weekend, to a stormy period in Queensland next week, to a looming hot stretch in the west - we have a mixed bag of weather ahead.
A cold outbreak has crossed southeastern Australia to end this week. There isn’t a lot of wet weather with it, but we are feeling the chill. Snow has fallen in Tasmania down to 500 metres, and in southern parts of Victoria’s alps down to 1500 metres, like here at Mt Baw Baw this morning.
Baw Baw sits at about 1500 metres above sea level in Victoria’s Southern Alps.
That chill will work its way up the east coast, reaching eastern NSW and southeast Queensland over the weekend, introducing showers near the coast that don’t add up to much, and cooler temperatures (high teens in Sydney, mid 20s in Brisbane). Meanwhile, it thaws out in the southeast after a widespread frost on Saturday morning.
All the dark and light purple shaded areas are at risk of frost on Saturday morning.
The next trough arrives in Queensland and far northern NSW on Monday, and may last for a few days. Another burst of widespread showers and thunderstorms thanks to the instability from the trough working with a feed of moisture from the Pacific Ocean. This trough may be located much further inland than the last one, giving a drink to more areas.
Rainfall observations in the 24 hours to 9am on Friday, October 28, and the potential rainfall for Monday, October 28.
This kicks off a week where we have high pressure stubbornly sitting over the Great Australian Bight. Being located south of South Australia we end up with cooler air pushed up through the eastern states, and warm air pushed down into the west.
With the high sitting there for an extended period we end up with day after day of cooler vs warmer.
For example, Perth is likely to reach the high 30s by later in the week. At the same time Melbourne will be peaking in the mid teens.
While it may continue day after day, it won’t last forever, there is always a change on the horizon. The outlook for temperature in the following week (beginning Monday 4th November) has the warmth shifting into the east, and a new cold outbreak sitting over the southwest instead.
