A more southeasterly pressure gradient occurred today but there were plenty of clouds with plenty of low level moisture.

Some low clouds possible overnight and in the morning tomorrow as predicted by the ACCESS model but not by other models with satellite images showing some low clouds inland.Some shallow low to middle level convective clouds also possible during the afternoon again predicted by the ACCESS model but not by other models.

Sea breezes likely return from Thursday with the west coast trough inland.Warmer temperatures with the west cast trough near the west coast.

Cooler maximum temperatures on Friday with a relatively strong sea breeze with the west coast trough inland and the southerly pressure gradient "bending" with solar heating.

Warmer maximum temperatures from the weekend again with the west coast trough near the west coast,west coast trough moving inland from Sunday and hence cooler maximum temperature with early sea breezes on Monday and Tuesday.


Some uncertainty on the precise synoptic conditions mid week next week.


The long spell with no 40+ Degree Days continues with the last 40+ Degree Day being Australia Day last year!With no 40+ Degree day within the forecast period,the next 40+ Degree Day will be at least the latest during summer as the 2005-2006 summer.
