Some post cold frontal showers occurred during the early hours today mainly over northwestern coastal areas,having contracted offshore as a land breeze developed,but the anvils from the clouds trapped under a subsidence inversion still spread a little inland during the morning like on Wednesday morning.
Skies clear by late afternoon.

Conditions rapidly become sunny and warm from the weekend as a ridge of high pressure builds.Hot conditions on Monday as a west coast trough deepens with warm air advection.Some middle and high level clouds though especially on Monday ahead of an upper/middle level trough/disturbance.

West coast trough likely moves inland back from Tuesday then some uncertainty with variation between models and model ensembles.A cold front possibly moves through the region on Wednesday with a weak ridge of high pressure over the region thereafter.
