Synopsis
A trough of low pressure across the northern Rockies will maintain onshore flow with periods of gusty westerly winds over the mountains and deserts through Monday. Low clouds and patchy fog will be extensive nigheights and mornings west of the mountains, clearing to the coast by afternoon. Weak high pressure will build over the Southwest on Tuesday, bringing warmer weather through the work week. Cooler weather likely returns by next weekend.

FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... Short Term
(Today through Tuesday)... Low clouds continue fill parts of the LA Basin at this early hour with clearing to the coast expected later this morning. Stronger onshore flow will persist across the region as a trough over the western U.S. begins to sag a bit to the southwest and flatten. Breezes will be a bit gusty into the mountains and deserts as we get into the afternoon and evening hours today. Wind gusts will range from 35-45 MPH with locally higher gusts possible along the 10 through the San Gorgonio Pass. Winds will still be a bit gusty in these regions on Monday, but not as high as today.

As the trough hangs across the region, temperatures will continue to be a bit below average through Monday with mostly 60s and 70s for daytime highs for the coast and western valleys. An area of high pressure will slowly expand into Southern California beginning on Tuesday, which will bring a warming trend through the middle of the week.

Long Term - Wednesday through Saturday
... The weak area of high pressure will trek across the region through Thursday with a shallower marine layer, where low clouds will continue across the coast and western valleys nigheights and mornings. 70s and 80s will make their way into the foothills and Inland Empire for daytime highs, with desert areas in the 90s to just above 100 near Palm Springs. Model consensus starts to diverge after Thursday. The ridge's reign may hang on a bit longer into Friday before a troughing pattern begins to take shape by next weekend. Though the strength and timing of this trough still remains a bit uncertain, our confidence of a cooler pattern by the end of next week remains moderate to high.

Marine
No hazardous marine weather is expected through Thursday.
