A warming and drying trend will continue through  the week. The

hottest temperatures will be Thursday and Friday.  Inland

temperatures will reach the 90s to lower lower 100s. Low 

temperatures in the mountains will remain warm overnight since 

those locations will be in the lower level temperature inversion. 

The marine layer will be compressed and held to the immediate 

coast.

Conditions will progress towards a warming trend as high pressure up

stream sets into the area. Starting Thursday we  will see RH values

in the low to mid teens for zones 283, 277, and 264. Interior

afternoon westerly winds will increase this week as well. Conditions

further heat up and dry through late week and the weekend.
