Area Forecast Discussion National Weather Service San Diego CA 654 AM PST Tue Jan 19 2021

SYNOPSIS. A surge of colder air from the northeast will feed a developing storm system southwest of San Diego today. Strong and potentially damaging easterly winds associated with the storm, will overspread the region today through Wednesday. Some precipitation is possible as well, with the best chance along the desert slopes and lower deserts. The storm will drift east across northern Mexico on Thursday, setting us up for quiet and seasonal weather Thursday afternoon through Friday. Another, larger winter storm drops south along the West Coast this weekend with widespread precipitation and cooler weather.

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

An upper low over central California this morning will move southwestward and be positioned around 30N/120W tonight, or some 300 miles southwest of San Diego. As this low moves south of our region, east to northeast winds will increase rapidly with strong and damaging winds expected. The winds look to become widespread given the dynamical forcing, so strong winds should even impact the coast (gusts to 45 mph). Further inland west of the mountains, wind gusts of 50-60 mph are forecast with localized gusts up to 80 mph along the coastal mountain slopes.

This offshore "Santa Ana" wind event will be atypical for SoCal. Given the influence of the upper low to the south, moisture will be drawn northward and this will lead to rainfall developing over the deserts and mountains with snow at the higher elevations and some light rain could work its way even west of the mountains, though light. Typically strong offshore winds are drying, but in this case we are seeing moisture moving in from the south. It will though be dry today though over the Inland Empire, Santa Ana mountains and inland Orange County and with the strong winds developing, fire weather conditions will be critical through this evening there - see Fire Weather discussion below for more details.

Our latest thinking on precipitation amounts is maximum over the San Diego County mountains (desert slopes) where storm total by Wednesday night when the storm departs will be near 2.5 inches, the San Diego County deserts are forecast to receive about an inch, Coachella Valley 0.25-0.50 inches. Eastern Riverside and San Bernardino County mountains near 1 inch liquid equivalent with snowfall of 2-4 inches above 5500 feet locally up to 8 inches with the heaviest snow occurring tonight where a Winter Weather Advisory has been hoisted (2 PM this afternoon through 6 AM Wednesday above 5500 feet).

The upper low will move east Wednesday through Wednesday night with precipitation ongoing, mainly deserts and mountains before coming to an end Wednesday night as the storm departs the region.

Thursday will see a break in the action before another storm from the north arrives Friday afternoon or evening and lasts through Saturday night. This will bring in colder air to the region which will last through early next week. We are still refining details on this storm from the north. Current precipitation totals Friday- Saturday night are projected to be in the 0.25-0.50" range for the coast and valleys, 1-1.5" for the mountains and less than 0.25" for the deserts. Snow levels will lower to 4000-4500 feet by Saturday with significant snowfall possible over the mountains. We are still refining the details on this storm.

A break will occur on Sunday before yet another winter storm from the north could impact SoCal early next week, potentially brining another round of at least moderate precipitation. An active weather pattern indeed!

AVIATION. 191030Z . Low clouds and fog with bases varying from 800-1600 feet MSL, tops to 1800 feet, and vis below 2SM in FG along inland extent of clouds such as around KONT. Low clouds will clear by 14Z, but not until 15-17Z in San Diego County. Higher clouds above 12000 feet MSL will continue to increase and lower to 6000 feet MSL during the day. Isolated -SHRA, with -SHSN in the mountains, are expected today and tonight, mainly in mountains and deserts.

Northeast winds will develop this morning, becoming widespread and very strong this afternoon. Areas of surface winds 20-30 kt gusts 40- 60 kt, including areas of LLWS and strong up/downdrafts. Airports most likely to experience strong winds will include KONT, KCNO, KRAL, KSBD, and KRNM.

MARINE. Gusty northeast to east winds will develop across portions of the waters mainly this afternoon and tonight, continuing Wednesday with wind gusts 25-30 knots at times, producing choppy seas and hazardous boating conditions. Winds will gradually diminish Wednesday night, with no hazardous marine weather expected Thursday through Saturday.

BEACHES. West-northwest swell and surf will peak this morning and gradually subside during the day. The High Surf Advisory, Beach Hazard Statement and Surf Zone Forecast contain all the details. No additional hazardous surf is expected after today.

FIRE WEATHER. A Red Flag Warning is in effect across portions of the Inland Empire, Santa Ana Mountains and Inland Orange County through 10 PM today. Northeast winds will be increasing and becoming strong and gusty today and lasting through this evening. These winds will then become more easterly and spread southward into San Diego County this afternoon and continue through Wednesday.

The strongest winds and lowest humidity will combine over the Inland Empire, the Santa Ana Mountains, and inland Orange County today. Winds will be northeast 25 to 35 mph with gusts 60 mph and isolated gusts to 80 mph below the Cajon and San Gorgonio Passes, and near the coastal foothills of the Santa Ana Mountains. The relative humidity for these areas will fall to 15 to 20 percent, then begin to recover tonight through Wednesday, with scattered showers breaking out. Winds will become strong and gusty from the mountains to the coast in San Diego County as well today through Wednesday, though the humidity will be higher at 20-30 percent. Widespread higher relative humidity values will be in place by Wednesday and another storm system will likely bring wetting rains across the region by this weekend.

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