Wintry blast for the southeast from Wednesday to Saturday

Southeastern Australia has only one day left of mild weather (Tuesday), before our first significant cold outbreak of the year sets in. Snow on the ranges, wintry hail for the rest, and a chill in the air that will feel more like mid-winter.

Tuesday is the last mild day for a while over southeast Australia.

A cold front will cross through on Wednesday, ushering in our first proper cold outbreak of the year.

The speckled cloud over the Great Australian Bight shows just how cold the air will be when it reaches the southeast, particularly from Thursday through to Saturday afternoon.

That type of pattern on the satellite indicates cold and unstable air, that has come up from Antarctica. It has rumbles of thunder and wintry hail, and as you go up in elevation the drops turn to snowflakes.

The satellite looks impressive, but the rainfall associated with it is only impressive for a few areas in the southeast - coastal parts of southeast SA, Victoria's southwest coast, eastern Melbourne, western Gippsland and up into the eastern ranges, much of Tasmania:

(more shortly on Queensland's next rain)

What a lot more people will notice is the chill. The blue indicates temperatures in the single digits, at night spreading right up into southern Queensland. The white is temperatures that are freezing.

With this comes snow.. but I'm very sorry to report that here at Jane's Weather we haven't quite got it ready to show that yet. :(

Our data scientists are working hard to put it together, but unfortunately, if you look up any mountain under Forecast at the moment you will find the forecast is a bit warm.

That is because the data shown is for elevations around 800-1100 metres, but those mountain peaks are actually up around 1500 - 1800 metres. Jane's Weather thinks you are down in the valleys.

We are hard at work fixing this and I'll let you know when it has been implemented.


The rain map also shows a lot of rain on the way for Queensland again.

Not the torrential, huge falls that lead to flooding, but a large area with significant rain.

This rain doesn't begin until early next week, it is at the very end of the outlook period. A high moves back into the southeast to calm things down there, but as it does it pushes moist air into Queensland that runs into unstable air (a trough) resulting in widespread wet weather.

I'll have more on that when it comes closer and there is more confidence in the forecast.
