That doona you pulled out from storage at the weekend to put back on the bed? Don't get too used to it being there.
Yes, it's a Victorian summer, and the weather is as variable as ever.
After a mild few days in Melbourne, with tops of 24 on Saturday and just 21 on Sunday and Monday, the mercury is creeping back to highs for appropriate beach weather - but only briefly.
A top of 29 is expected on Tuesday, and 28 on Wednesday, but Thursday is the warmest day of the week.
In Melbourne, the mercury is tipped to reach 39. Mildura is again expected to be the warmest city in the state, with a top of 43 forecast, with 42 expected in Horsham and Swan Hill, 41 in Echuca and 40 in a number of other centres including Albury, Bendigo and Geelong.
That heat has brought the Country Fire Authority's fire danger ratings for much of the state to very high, and for the north central, south west, Wimmera and central districts, which includes Melbourne, the rating is severe.
Overnight Thursday, the minimum is predicted at 24, but Friday will see a change. With the chance of thunderstorms in the late morning and early afternoon, Friday is tipped to reach 27. Showers are possible on Saturday morning, with a top of 24 expected.
