The coast and valleys will warm on Monday with the greater warming for inland areas for Tuesday through Thursday.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
.SHORT TERM (Today through Sunday)...
High temperatures increase slightly today for inland and desert areas while mountain and coastal temperatures remain similar to yesterday. The marine layer will make its move back in over the coast and into the coastal basin late this afternoon to settle in for the evening through tomorrow morning. The marine layer is expected to deepen for Saturday morning bringing chances for patchy drizzle for the coastal mountain slopes all the way to the coast.
Winds will increase Saturday afternoon as onshore flow strengthens over the area. Expect periods of gusty southwest to westerly winds through late Sunday. Highest wind speeds will be in the deserts, desert mountain slopes and mountain passes with gusts up to 40-50 mph, locally up to 65 mph. Daily high temperatures begin to cool area wide over the weekend with temperatures Sunday near to a few degrees below average.
.LONG TERM (Monday through Thursday)...
Temperatures begin to warm along the coast and in the Valleys Monday, then area wide Tuesday. Daily highs will continue to increase through the week, peaking Thursday afternoon. Temperatures Thursday will be up to 5 degrees warmer than average over most of the area. The high deserts will see temperatures 5-10 degrees above average.
