Area Forecast Discussion National Weather Service San Diego CA 100 PM PST Mon Feb 24 2020

SYNOPSIS. Fair and warmer weather is expected this week under building high pressure and offshore flow. Gusty east to northeast winds are expected through passes and along coastal foothill areas Tuesday through Thursday. Our next chance for showers comes late Sunday into Monday as a cold storm system drops down the Coast.

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

Skies were clear across the forecast area early this afternoon. Surface pressure gradients were trending offshore and a wind shift from the north with gusts over 25 MPH was noted at some sites over northern portions of the forecast area.

A strong sfc high will build south over the Rockies/Great Basin tonight through Wednesday. The increasing pressure gradient and cold air surge will result in Santa Ana conditions over SoCal Tuesday through Thursday with low RH and gusty winds in the usual wind- prone areas. A Wind Advisory has been posted over most of the mts and into some valley areas as well. Some wind gusts to 50 MPH are expected, but a few hot spots in the wind-prone areas could easily top that. Much of the coast will be spared the wind, but will feel the heat as temperatures rise to 8-15F above average. The nights should still be quite cool where winds drop off, but temps will remain elevated in windy areas.

The warm conditions will persist into Friday, even as high clouds thicken ahead of a weak subtropical system. Of more concern will be a cold trough digging south along the Coast this coming weekend. The various global models have been consistent digging this system and the associated ensembles have been mostly wet over SoCal as well, so POPS have been increased a bit. There is still a lot of time and model runs to confirm, and this type of system is inherently tricky to forecast. If it develops to full potential, we could get some significant precipitation late in the weekend or early next week.

AVIATION. 242055Z . Coast/Valleys . Mostly clear skies and unrestricted visibilities. Increasing northeast winds to around 25 knots with higher gusts below canyons and passes. Moderate to strong up and downdrafts along with wind shear can be expected near the mountains. The risk of low clouds at the coastal airfields tonight into Tuesday morning is low, so confidence in clear skies and unrestricted visibilities in the KSAN TAF is high.

Mountains/Deserts . Mostly clear with unrestricted visibility through Tuesday. Increasing northeast winds to around 25 knots with higher gusts through canyons and passes, moderate to strong up and downdrafts, and wind shear near the mountains can be expected.

MARINE. No hazardous marine weather is expected through Thursday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory from 10 AM Tuesday to noon PST Thursday for San Diego County Mountains-San Diego County Valleys.

Wind Advisory from 4 AM Tuesday to noon PST Thursday for Riverside County Mountains-San Bernardino County Mountains- San Bernardino and Riverside County Valleys-The Inland Empire-San Gorgonio Pass Near Banning-Santa Ana Mountains and Foothills.

PZ . NONE.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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