SYNOPSIS
Dry and warmer today through early next week with high temperatures near to around 5 degrees above normal inland by Monday. Gradual cooling follows Tuesday through Saturday. Areas of night and morning low clouds and fog continuing through next week, becoming more widespread towards the middle of the week as the marine layer deepens. Afternoon and evening winds will strengthen slightly across the mountains and deserts for the latter half of the week.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
SHORT TERM
Clear, sunny skies are present across the region today under weak high pressure aloft. No surprises today, with afternoon high temperatures near normal for coastal areas to a touch (up to about 5 degrees) below average inland and seasonal afternoon breezes, including a good sea breeze for the coast and valleys. Some patchy, shallow low clouds will develop near and along the coast in the small hours of the morning Sunday, then clear later in the morning.
Not much change from today into early next week, except for variations in temperature. Sunday will be warmer than today, with high temperatures near normal along the coast to about 5 degrees above average inland. Monday will be similar to Sunday but a tad cooler west of the mountains, as a weak trough moves through the weakly cyclonic flow aloft, and a touch warmer for the mountains and deserts. The slow cooling trend along the coast Monday and Tuesday will spread inland starting Wednesday, as another weak trough moves through the region. Afternoon and evening winds will strengthen slightly in the mountains, passes, and deserts as well due to the trough Wednesday, with peak gusts through the wind- prone passes of 40-50 mph. Nightly and morning low clouds that will start out shallow and confined to coastal regions will gradually get deeper (cloud bases higher in the atmosphere) and further inland mid to late week.
LONG TERM
The cooling trend will continue for the region through at least Saturday with continued broad low pressure aloft over the western U.S. Temperatures will be below average likely by about 5 to 10 degrees Friday and Saturday. Another weak trough moves into the region Friday which will likely bump winds in the mountains and deserts up again for Friday and likely Saturday. Long-term ensemble models are in good agreement through late Friday, after which there are still large differences in the strength and position of a likely stronger low pressure moving from the Pacific Northwest into the western U.S. There is good confidence in below average temperatures and breezy mountain and desert winds, but the degree of cooling and strength of winds depend on where the low pressure goes, as well as how deep the marine layer could get with possible drizzle resulting. Both the GEFS and ECMWF ensemble have backed off on what little precipitation chances they were previously showing for Sun-Mon, and the weather will very likely remain dry, besides chances for drizzle.

Coasts/Valleys
Mostly clear skies expected through tonight. Patchy low clouds may develop along the coast after 10Z Sun. There is a 30 to 60 percent chance of BKN-OVC cigs developing within 10 miles of the coast. Where low clouds develop, cigs will likely be 700-1000 ft MSL. There is a 25 percent chance of fog with visibility 1 mile or less developing along the coast. Any low clouds or fog that develops along the coast should clear by 18Z Sun.
Mountains/Deserts...Clear skies with no visibility restrictions into Sunday.
MARINE
No hazardous marine conditions are expected through Thursday.
