SYNOPSIS

High temperatures will remain as much as 5 to 10 degrees below average for the mountains and inland valleys through Thursday. High temperatures will warm a few degrees each for Friday and Saturday and cool a few degrees each for Sunday and Monday. A warming trend will begin on Tuesday with high temperatures returning to around average on Wednesday of next week. Night and morning coastal low clouds will spread inland across much of the valleys for early today and early Thursday. The marine layer will become shallower by the weekend with coastal low clouds not spreading inland much past the far western valleys.

SHORT TERM (Today through Friday)

Low pressure moving southward into California today will weaken and move east on Thursday and Friday. High temperatures will remain as much as 5 to 10 degrees below average for the mountains and inland valleys for today and Thursday with high temperatures ranging from the lower to mid 70s near the coast to the lower to mid 80s for the Inland Empire with the lower deserts in the mid to upper 90s. High temperatures will warm a few degrees each for Friday and Saturday with the slightly greater warming for the mountains and inland valleys on Saturday.

The marine layer will remain around around 2500 to 3000 feet deep into Thursday with night and morning coastal low clouds spreading into much of the inland valleys late each night. The marine layer will become shallower for Friday into the weekend with night and morning coastal low clouds not spreading inland past the far western valleys.

LONG TERM (Saturday through Tuesday)

Low pressure will weaken across California for Friday and Saturday with weak low pressure off the California coast on Saturday moving into central and southern California on Sunday and Monday with limited moisture. High temperatures will warm a few degrees for Friday and Saturday, then cool a few degrees for Sunday and Monday.

High temperatures on Saturday will be a few degrees above average for lower deserts and a few degrees below average for most other areas with high temperatures ranging from the 70s near the coast to the mid 80s to lower 90s for the Inland Empire with 100 to 104 for the lower deserts. With the cooling, high temperatures on Monday will range from the lower to mid 70s near the coast to the 80s for the Inland Empire with the lower deserts around 100.

For the middle and latter part of next week, high pressure to the east is expected to strengthen, bringing a warming trend to southwestern California for Tuesday through Friday, though with increasing uncertainty and model spread in just how much warming may occur. The NBM 50th percentile high temperatures for Wednesday of next week are within a few degrees of average for most locations.
