Both the Bureau and GFS models are in agreement for some useful falls of rain and a cold air mass entering the state by next weekend. Rainfall totals of the order of 60 to 80mm may be expected in some locations in extreme eastern Victoria and South – East New South Wales by Saturday morning. This system is exited to be preceded by a hot airmass with gusty North westerly winds affecting air from central Australia.
Once the system moves through, temperatures will drop rapidly. Meanwhile, it is more than likely that flooding may occur in the regions affected particularly the low lying regions. One to watch at this point.
Rain is needed in many parts of the country where lower than average precipitation has been recorded so far this spring and in some cases for longer. It seems possible that more follow up rain in the following week may also be on the cards.
Update: Models have downgraded this event with only the chance of precipitation Saturday night into Sunday as a not so vigorous system passes through.
Now the models have again come through with significant rainfall across SE Australia during Sunday. This is anticipated as an upper trough rapidly moves across the state. Widespread falls of 20 to 30mm is expected across southern NSW and eastern Victoria.
