A weak cold front brushed the region late on Monday night having brought some light showers.Only the slight chance of showers or drizzle for the next few hours with low level clouds associated with moist low level air.

On Tuesday,cloud cover in the morning clears by afternoon as a subtropical high pressure ridge strengthens to the south.

Rapidly warming and drying conditions thereafter with a subtropical high pressure system to the south and a west coast trough forming near the west coast leading to some warm air advection.

The west coast trough moves inland from Thursday afternoon with strong sea breezes expected on Friday in the afternoon and evening as the southerly pressure gradient "bends" with solar heating.

Easterly pressure gradient rapidly reestablishes over the region with a strong subtropical high pressure system moving to lie south of the region.
