Area Forecast Discussion National Weather Service San Diego CA 115 PM PST Sun Dec 8 2019

SYNOPSIS. A cold front will move across Southern California overnight. preceded by periods of showers, and followed by clearing skies on Monday. Weak high pressure aloft will bring sunshine and slightly warmer weather through Wednesday. Even warmer weather is on tap for the latter half of the week as high pressure aloft strengthens.

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

At 1 PM PST . Radar showed numerous showers entering northern portions of the forecast area. Some had briefly moderate rainfall rates. So far, no lightning has been detected, but an isolated strike or two is possible. Rain gauges over the past couple of hours show widespread light amounts of under 1/10 inch. A full rainfall summary for this event is headlined on our webpage. Satellite imagery showed the higher clouds thinning over the CWA, with lower, more cumuliform types to the north. West winds were still gusty through the passes up to 40 MPH.

For the remainder of the day into tonight, scattered showers will continue. Isolated heavier rainfall rates are likely as the airmass becomes more unstable due to the colder air arriving from the north. A break in the clouds has allowed some sfc heating over northern areas, which could contribute to larger sfc-based cape values and briefly heavier shower potential. A more organized area of showers will move east, north of San Diego County this afternoon. The leading edge of the cold pool aloft and main trough axis will arrive later this evening and overnight with another round of showers. The snow level is still above 7500 FT but should fall below that this evening and down to neat 6000 FT late tonight. This could still result in several inches of snow accumulation, mainly above 7500 FT.

A weak low pressure system will drop south over CA tonight, accompanied by scattered showers and some snow at the higher elevations. The trough axis is forecast to pass the forecast area before sunup on Monday, clearing out the showers and most of the cloud cover. This will set us up for a mostly sunny day on Monday. A weakening shortwave ridge follows for slight warming on Tuesday, and another weak trough on Wednesday. Other than a period of high clouds, the weather will stay fair and mild through Wednesday as these systems pass.

For the latter half of the week, continued height rises over SoCal associated with a strong ridge centered offshore will bring warmer weather with high temperatures from 5-10F above average. Shortwaves in strong westerly flow aloft will begin to knock down the ridge next weekend, sparking a cooling trend that could hold into next week but no significant precipitation is expected.

AVIATION. 082120Z . Coasts/Valleys . BKN-OVC cigs with bases 1500-2500 ft MSL, locally 600-800 ft MSL at times through tonight. Reduced vis 2-5 miles expected in areas of -RA. SCT clouds blo 3000 ft MSL after 17Z Monday.

Mountains . -RA will continue at times through this evening with some -SN above 6000 feet MSL. Widespread terrain obscurations in - RA/-SN/FG will continue. West winds with gusts to 35 kt over the mountains will bring weak-moderate up/downdrafts and LLWS over and east of the mtns through 06Z Mon.

Deserts . Isolated -RA possible through tonight with BKN-OVC cigs 4000-7000 ft MSL. Local vis 2-4 miles at times in -RA through this afternoon. Otherwise, SCT-BKN clouds expected at or abv 12000 ft MSL through tonight.

MARINE. Scattered rain showers at times through tonight. Combined seas of 6 to 8 ft will continue through this evening, diminishing by Monday morning. Otherwise, no hazardous marine weather is expected through Wednesday.

BEACHES. A High Surf Advisory remains in effect through 4 AM Monday for long- period west to northwest swells of 10 to 14 seconds. Swells will steadily subside through Monday morning. Surf of 5-8 ft will continue through tonight in San Diego County, with 4-7 ft surf on beaches prone to WNW swells in Orange County.

SGX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory until 4 AM PST Monday for Orange County Coastal Areas-San Diego County Coastal Areas.
