Some low level clouds occurred earlier today due to low level moisture as predicted by ACCESS model but not other models.
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.
Some marine layer clouds expected during the morning and afternoon as predicted by ACCESS and ECMWF models(morning).
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.
Possibly hot to very hot conditions late next week with the west coast trough deepening down the west coast with warm air advection,though still some uncertainty this far out with variation between models and model ensembles.
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.
