SYNOPSIS

Slow warming will continue for the inland areas through mid week, bringing high temperatures to 5 to 10 degrees above average on Thursday for the mountains and deserts. The coast and valleys will cool a few degrees today, then warm a few degrees for Wednesday and Thursday, with night and morning coastal low clouds spreading into portions of the valleys late each night. A low pressure system moving into the western states will bring a cooling trend for Friday through the weekend, with high temperatures for next Sunday falling to a few to around 5 degrees below average.

SHORT TERM (Today through Thursday)

High temperatures for the coast and valleys will be slightly cooler today with the mountains a few degrees warmer. High pressure aloft will bring warming for Wednesday, as much as 5 degrees for the mountains and inland, with a few more degrees of warming for most areas on Thursday.

High temperatures on Thursday will be a few degrees above average near the coast to 5 to 10 degrees above average for the mountains and deserts. High temperatures on Thursday will range from the lower 70s near the coast to the mid 80s to mid 90s for the Inland Empire with 104 to 108 for the lower deserts.

Night and morning coastal low clouds will spread into portions of the inland valleys for early today and early Wednesday, then just into the western valleys for Wednesday night into Thursday morning.

LONG TERM (Friday through Monday)

A low pressure system moving into the western states will bring a cooling trend for Friday through Sunday, continuing into the deserts on Monday as the coast and valleys begin to warm. High temperatures on Sunday will be a few degrees below average to around 5 degrees below average for the inland valleys. High temperatures on Sunday will range from around 70 near the coast to the upper 70s to mid 80s for the Inland Empire with the lower deserts around 100. Night and morning coastal low clouds will spread farther into the valleys late each night as the marine layer deepens.
