Area Forecast Discussion National Weather Service San Diego CA 928 PM PST Tue Nov 24 2020

SYNOPSIS. Seasonally cool weather through Thursday will be followed by a Santa Ana pattern Friday through Sunday that will bring sunny, warmer days and clear, cool nights. Gusty northeast winds will begin Thursday in the mountains and foothills, then lower into the valleys in the afternoon and evening. The strongest winds will surface Thursday night and Friday. The winds will be lighter over the weekend.

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

Highlights:

* Seasonally cool Wednesday and Thursday with marine layer clouds returning. * Gusty Santa Ana winds Thursday through Saturday, strongest Friday morning. * Warmer days Saturday and Sunday with lighter winds. Very low humidity.

Update: The sky remains clear across the service area this evening. Some low cloudiness could make a comeback late tonight especially towards dawn Wednesday along the coast. Otherwise, tranquil weather prevails. See previous discussion below for forecast details.

Previous Discussion:

A strong trough moving into the Pacific Northwest this afternoon will deepen and dig southeast across the Great Basin Wednesday. Onshore flow ahead of this trough will bring a surge of low level moisture and marine clouds back into the coastal zones and western valleys tonight and tomorrow morning. Therefore, the usual diurnal clearing back to the coast may be slowed by the increasing onshore flow in the afternoon, and some areas within a few miles of the coast may only see partial clearing tomorrow afternoon. The clouds surge back inland Wednesday evening as the onshore gradients peak ahead of the advancing trough.

The trough axis passes by early Wednesday night, and that sets the stage for a Santa Ana wind event Thursday and Friday. The 12Z models and their ensembles are a little faster and a little stronger with the Santa Ana winds. Gusty northeast winds will initially surface in the San Bernardino Mountains early Thursday, then strengthen and expand into the Inland Empire and inland Orange County Thursday afternoon. Winds in these areas will gust from 35-45 mph with peak gusts of 50-60 mph in the wind prone passes and canyons like the Cajon Pass and the passes in the Santa Ana Mountains. San Diego County will be spared from this initial burst of winds, but the easterly winds will increase later in the day with the strongest winds arriving Thursday night into Friday. Weak to moderate strength winds will continue Friday night into Saturday, followed by weaker and more localized east winds Sunday and Monday.

A Fire Weather Watch was issued and will take effect on Thanksgiving Day. It will run from 2 PM Thursday to 10 PM Friday in San Bernardino, Riverside and Orange Counties. In San Diego County it will start a little later, beginning at 9 PM Friday and going through 2 PM Saturday.

After a cool day on Thanksgiving, there will be a steady increase in temperatures Friday through Sunday, with the most notable warming west of the mountains with downslope flow pushing temperatures into the 80s Sunday. The warm, dry weather will continue into Monday before turning a little cooler Tuesday and Wednesday.

AVIATION. 250430Z . Coast/Valleys . Weak offshore flow will help keep any low clouds off the coast for most of the night. Patchy low clouds possibly developing 12-16Z along the coast and up to 10 mi inland with bases near 1500-2000 ft MSL. Most locations should become SCT around 18-20Z, then clouds will begin to move back inland around 26/02-04Z with bases near 2500 ft MSL, spreading into the valleys Wed night.

Mountains and Deserts . Mostly clear with unrestricted vis through Wednesday evening.

MARINE. No hazardous marine weather through Thursday afternoon. Gusty northeast winds in excess of 20 kt may develop over portions of the coastal waters at times Thursday evening through Friday morning.

FIRE WEATHER. A Fire Weather Watch was issued and will take effect on Thanksgiving Day. The Watch will be in effect from 2 PM Thursday to 10 PM Friday in San Bernardino, Riverside and Orange Counties. In San Diego County the Watch will start a little later, beginning at 9 PM Friday and going through 2 PM Saturday. The Fire Weather Watches were coordinated with the Oxnard office and with the Storm Prediction Center Fire Weather Desk.

The northeast winds will start out in the San Bernardino County Mountains Thursday morning, then strengthen and lower into the Inland Empire and inland Orange County Thursday afternoon. The winds will reach the San Diego County Mountains Thursday evening. The most recent model output has forecasted the winds speeds to be 5 to 10 mph higher than the previous runs, and this has been reflected in todays forecast. Peak gusts of 50 to 60 mph are likely in the most wind prone areas of the back country, with a few gusts to 65 mph.

The most widespread and strongest winds will take place Thursday night and Friday. Moderate strength winds will continue Friday night into Saturday, strongest in the east-west passes of San Diego and Riverside County, and a little weaker in San Bernardino County. The winds will be weaker in all areas Sunday and Monday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Fire Weather Watch from Thursday evening through Saturday afternoon for San Diego County Inland Valleys-San Diego County Mountains-Including The Palomar And Descanso Ranger Districts of the Cleveland National Forest.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
