Plenty of low level clouds were present today with moist low level air.The low clouds will clear tomorrow morning with drier low level air.

Plenty of high clouds however will be present tomorrow with tropical moisture from a tropical weather system in the Southern Indian Ocean streams aloft in a subtropical jet stream.

A cold front likely moves over the region on Saturday bringing a colder air mass,and the slight chance of showers.Then high pressure ridge rapidly builds to the south leading to clearing conditions.

A west coast trough forms near the west coast next week leading to slight warm air advection.

The west coast trough likely moves inland back by next Thursday.
