SYNOPSIS. A slowly rebuilding marine layer will produce some fog and coastal low clouds into Tuesday morning. Stronger onshore flow will produce gusty mountain and desert winds, and draw the cooling farther inland. By early Wednesday, a deep marine layer will produce drizzle or scattered, light rain showers over the coastal basin. A passing wave aloft will cause further deepening of the marine layer onto the coastal slopes with pockets of higher elevation dense fog and additional chances of showers over and west of the mountains. It will be much cooler both Wednesday and Thursday, then dry and warmer to end the week as weak ridging develops over the Southwest.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

Skies were clear over all of SoCal at midday, with a fog/low cloud bank near the islands headed SE. The sfc pressure gradients across SoCal were weak and winds reports were light. It was very warm inland where temps were running a few degrees F above yesterday at Noon. The immediate coast was still in the 70s.

Today was the last very warm day for awhile as a trough slowly develops over California through the mid week period. Stronger westerly winds will develop through and below the desert passes later this evening and strengthen on Tue into Wed when gusts of around 50 MPH and locally higher are likely on the desert slopes. The increasing onshore flow will build the marine layer onto the coastal slopes resulting in higher elevation fog and possible rain and scattered, mostly light rain showers over the coastal basin. Wednesday through Thursday. Depending on instability, a few heavier showers will not be out of the question Thu afternoon, especially over San Bernardino County.

The upper-level trough will exit the region late Thursday, setting up a warming trend into the weekend under building high pressure aloft. Temperatures will be well below average on Wed/Thu, rising to about average over the deserts by Friday, and the rest of the region over the weekend.

At this time, it appears some fog could reach the beaches this afternoon, perhaps dissipating and then reforming later tonight. A few hours of dense fog late tonight or early on Tuesday is possible either coastal or mesas. Wind Advisories will likely be needed for the mts/deserts by late Tue. Precipitation is looking more likely and should mostly total one-tenth inch or less west of the mts Wed/Thu with little runoff potential, but roads could be slick during commute times. The only caveat to this is for Thu afternoon under a possible cold core upper low, and mainly over San Bernardino County. Cape values may be elevated enough then for isolated thunder. NBM has it running near 10% over the high desert and mountains. It is not in the grids or forecast now, but will be monitored.

Looking ahead to next week . An ensemble consensus is building for a widespread, wetting rain, and even some high-elevation snow on Monday. POPS have been adjusted accordingly.

AVIATION. 192015Z . Coast/Valleys . Patchy very low stratus/fog will be likely along the immediate coast of San Diego County 23Z today-02Z Monday but should not impact any airports except possibly KNRS. Bases could be 500 feet MSL or less with local vis around 1 mile. Otherwise, clear skies with unrestricted vis will occur through this evening. Areas of low clouds/fog will develop along the coast after 08Z Tue and gradually spread up to 10-15 miles inland by 14Z Tue, including at KSAN, KCRQ and KSNA. Cloud bases are low confidence but initially could be 400-600 ft MSL with bases possibly rising to 700-1100 ft MSL by 14Z Tue. Areas of vis 2-4 miles will occur 08Z-16Z Tue with local vis below 1 mile in fog over higher coastal terrain. Most areas should clear by 17Z Tue.

Mountains/Deserts . Clear skies with unrestricted vis will continue through Tuesday morning.

MARINE. Northwest winds with gusts near 20 kt will occur across portions of the outer coastal waters this evening and again Tuesday evening. Otherwise, no hazardous marine conditions are expected through Saturday.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
