Area Forecast Discussion National Weather Service San Diego CA 850 PM PST Fri Jan 15 2021

SYNOPSIS. Dry weather with periods of gusty Santa Ana winds will continue through Saturday night. Above average high temperatures will continue through the weekend. This will be followed by a cooling trend as a low pressure system comes from the north. This will bring strong, potentially damaging, northeast winds late Monday through Tuesday night. There is also a growing chance of showers Tuesday and Wednesday, highest in the mountains and deserts.

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

Seventeen (17) record highs were set in our forecast area today. That may be a record for the most number of broken records in one day! The highest high was 94 at Vista and Santa Ana, and the lowest high was 67 at Big Bear Lake. We also hold the distinction of having the nation's high of 96 at Santee.

Tomorrow and Sunday will be very warm days too, perhaps not quite as warm as today, but still way above average for mid January. The offshore gradients will be a little weaker tomorrow and that will allow a sea breeze to kick in a little earlier at the coast and be a little stronger. So instead of 88 at the airport, the high tomorrow may be closer to 78. The record high is 86. Record highs within reach tomorrow include Ramona (84), Palm Springs (88), Indio (86), Borrego (83) and Big Bear Lake (63).

Sunday and Monday will also be mild and dry with upper ridging aloft and weak offshore flow at the surface.

Next week the long-wave pattern over the Pacific transitions from the "resilient ridge of high pressure" to a "series of shortwaves" that will impact the West Coast through the end of the month. Monday will be the last warm day for a while because a strong, deep upper low will settle over SoCal Tuesday and Wednesday. Northerly winds look quite strong Monday night and Tuesday, and rather widespread, impacting not just the mountains and foothills, but a lot of the metro areas too. Some gusts should exceed 60 mph in the mountains and foothills, perhaps higher in the back country. Gusts may top 40 mph in the valleys.

Moisture gets wrapped into this system and there is growing confidence in showers over the mountains and deserts, and perhaps the coastal and valley areas too on Tuesday and Wednesday. But at this time the mountains and deserts have the best shot at precip due to the east-northeast wrap-around flow on the north side of the low that dives offshore west of Baja. Ensembles and model clusters continue to indicate possibilities ranging from totally dry to rather wet, but the guidance is trending wetter.

The low off Baja moves east Thursday, but another trough is poised to bring more precipitation next weekend.

AVIATION. 160400Z . Mostly clear with FEW-SCT high clouds AOA 20K FT MSL and unrestricted vis through Saturday. Localized N/NE surface winds 10- 20 kt with gusts to 30-35 kt after 16Z Sat in areas from the mountain crests west into the foothills and some valleys, especially in the Inland Empire east of KONT. Weak-moderate up/downdrafts and LLWS possible over and W/SW of the mountains.

MARINE. No hazardous marine conditions are expected through most of Monday. Gusty offshore winds will be likely across the waters starting Monday night into Tuesday.

BEACHES. Long-period swells from the WNW will continue through Tuesday. High surf is likely at times Sunday through Tuesday, primarily at beaches in southern San Diego County. See the Beach Hazard Statement for details.

FIRE WEATHER. Dry weather will continue through Sunday with lowest daytime humidity around 5 percent this afternoon, then 10-20 percent Saturday and Sunday. Santa Ana winds will continue to decrease this afternoon. The next round of Santa Ana winds will develop Saturday morning, peak Saturday afternoon into Saturday night with strongest gusts 40-45 mph, then diminish Sunday. With humidity remaining quite low Saturday, the red flag warning continues through 4 pm Saturday.

Another round of more widespread and stronger northeast winds develops on Monday, peaks late Monday night through Tuesday, then slowly subsides Tuesday night and Wednesday. Humidity looks higher and is expected to stay above 20 percent, mitigating critical fire weather. Chances are increasing for showers across the region, most likely in the mountains and deserts.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Red Flag Warning until 4 PM PST Saturday for Orange County Inland Areas-Riverside County Mountains-Including The San Jacinto Ranger District Of The San Bernardino National Forest-San Bernardino County Mountains-Including The Mountain Top And Front Country Ranger Districts Of The San Bernardino National Forest-San Bernardino and Riverside County Valleys -The Inland Empire-Santa Ana Mountains- Including The Trabuco Ranger District of the Cleveland National Forest.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
