Area Forecast Discussion National Weather Service San Diego CA 1223 PM PST Fri Dec 6 2019

SYNOPSIS. A moist, southwest flow aloft will bring increasing clouds, with a chance of some light rain by evening. The clouds will persist through the weekend, along with a chance for periods of light rain showers as a weak storm system drops south across the State. It will move east on Monday, with clearing skies and a warming trend for next week. Further warming is on tap for next weekend as dry weather persists. At the beaches, a large west swell bring high surf this weekend.

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

Satellite imagery at midday showed a thicker blanket of high clouds spreading NE across the area. In addition, the radar indicated some precipitation moving NE over the coastal waters. Some of this could make it into Orange and San Bernardino Diego Counties by late afternoon. The sfc pressure gradients from the deserts were still weak to moderate offshore, supporting NE winds below the passes with local gusts 25-35 MPH. Still, the sea breeze was evident into the western valley areas.

A storm system centered 500 miles west of Cape Mendocino today, will drift east through Saturday, and then drop south through Monday as a strong ridge builds off the Coast. Weak disturbances off the Pacific ahead of it will gather up some Pacific moisture, sparking some occasional light precip that will favor the coastal slopes. Upslope is generally weak though, so no heavy amounts are likely with no good atmospheric lift to squeeze it out. Snow levels will be quite high initially, above 8K FT through Saturday, then fall to around 7K FT by late Sunday.

The final trough axis passes through SoCal on Monday morning, so some light, scattered showers may continue into early Monday for San Diego County especially. Overall precip amounts of 1/4-1/2 inch are expected west of the mts, and 0.5 to 1.5 inches on the coastal slopes and higher terrain. For the deserts, less than one-quarter inch total. Several inches of snow are possible in the San Bernardino Mts by Mon morning above 7500 FT.

A highly amplified ridge develops early next week along the West Coast and keeps SoCal protected from activity in the westerlies through next week. Even though the ridge flattens, it strengthens further next weekend along 30N latitude. This will likley bring well above average temps to SoCal by next weekend, along with continued fair and dry weather.

AVIATION. 062020Z . Coasts/Valleys . SCT-BKN high clouds AOA 20000 ft MSL and unrestricted vis this afternoon. Cigs 2000-2500 ft MSL and vis 2-4 SM in areas of RA after 01Z Sat.

Mountains . SCT-BKN high clouds AOA 20000 feet MSL with unrestricted vis through this afternoon. Low clouds will obscure terrain above 3000 ft MSL, with vis 1-3 SM at times after 01Z Sat with -RA/-SN.

Deserts . Mostly clear skies through Fri. Chance of -RA Sat. Cigs around 5000 ft MSL and vis 3-5SM possible in RA.

MARINE. Scattered rain showers this afternoon through Sunday. Combined seas of 6 to 8 ft are expected Saturday afternoon through Sunday evening.

BEACHES. A High Surf Advisory has been issued as long-period northwest swells of 14 to 18 seconds arrive at the coasts of Southern California. The swells will start to build on Saturday, peaking Sunday morning, and subsiding by Monday morning. Surf of 6-8 ft is expected in San Diego County and 4-7 ft surf is expected on beaches prone to WNW swells in Orange County.

SKYWARN. Skywarn activation is not requested.
