The Week Ahead:
The marine layer will become more shallow through Wednesday. High pressure increasing over the region will send temperatures on a slow climb. Fog may be possible as the marine layer shallows out under the high pressure.
Low pressure trough will begin to enter the region Thursday. This will weaken the high pressure over the West Coast and temperatures will take a small dip.
Clouds will strengthen again with the increased onshore flow Thursday into the weekend. The onshore flow will bring back gusty winds in the mountains and deserts. Morning drizzle will be possible overnight Thursday through Saturday under the strengthening marine layer.
