Steady warming trend from here. Thinking Melbourne should see it’s first 30C on Saturday and at least some suburbs will approach 35C on Sunday. Monday depends a bit of the timing of the front, but more likely 20s. Northwest will see mid to high 30s Friday to Monday. Will get very windy up there, so would not surprise to se fire weather warnings posted at the same time as areas are affected by river floods
Warmth down here in Tas tends to peak in the mid to high 20s, and cool down tends to happen on Sunday.
Not a lot of rain with this system. TAS looks better, and may well get moderate falls, but Vic likely to be hit and miss.
Progs are showing a very dry two weeks ahead for much of Oz with very high temperature developing in the northern subtropics. EC and GFS have been nudging 50C in the Pilbara by the end of the week coming up. Exceptional heat in La Niña in summer does happen during breaks in the wet, so be interesting to see where that heat goes. Currently looks to stay well north of us in the southeast.
