Area Forecast Discussion National Weather Service San Diego CA 930 PM PDT Tue Jul 7 2020

SYNOPSIS. Cooler weather will continue through Wednesday before high pressure strengthens across the Southwest late in the week and brings increasing heat again. Night and morning low clouds will continue near the coast and occasionally into the valleys the next few nights, though with a decrease by the weekend. Temperatures could reach the 115 to 120 degree range in the lower deserts this weekend, with some temperatures above 100 degrees in the Inland Empire. Only slight cooling is expected early next week.

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

Areas of stratus were near the beaches and over the coastal waters, with clear skies inland. The stratus will be a bit slow to form overnight but should eventually cover most San Diego County coastal areas and a few valleys and parts of the Orange County coast by late tonight. With just a moderate strength marine inversion, most areas should clear by mid-morning Wednesday.

A broad long-wave trough covered the northeast Pacific and most of the western 1/3 of the US while a ridge extended from the central US southwest to Baja California. The longwave trough will continue over the NE Pacific through the weekend while the ridge builds west over the Southwest. The ridge will bring gradually increasing heat Thu- Sun, with some 850 mb temps possibly exceeding 30 deg C this weekend. If the atmosphere stays dry, hottest desert locations could reach 120 this weekend, and over Imperial County, some of the ECMWF ensemble solutions show maximum temperatures as high as 124-125 deg F. The ridge axis becomes east-west over our area starting Friday after an initial period of some south flow around the west side of the high, and this will bring some moisture, enough for some afternoon cumulus over the mountains. The best moisture likely will stay to our south and east, and instability stays low (based on current models, though this sometimes changes as we get closer to the date), so most likely will we not have any thunderstorms. If a near-surface moisture surge moves northwest from the Gulf, lower desert temperatures will be cooler than the 115-120 that is currently in the forecast, but west of the mountains would likely end up above current forecasts of 90s to near 100 in the San Diego County valleys and 100-107 in the Inland Empire due to weakening of the onshore flow in a more moist/cooler desert scenario. The excessive heat watch looks good for the deserts for the weekend, but one may be needed in the Inland Empire if temperature forecasts increase any there.

Looking into next week, the ensembles have a slight decrease in temperatures around Mon/Tue, but hot weather will continue over most inland areas as the upper high likely only shifts a little bit to the east. We will likely be on the northwest edge of greater mid- level moisture, so any shift to more southeast flow could bring the onset of summer convection in the mountains.

AVIATION. 080400Z . Coast/Valleys . Areas of stratus will develop along the coast through 07Z, then spread up to 25 miles inland by 12Z Wed. BKN/OVC cloud bases will mostly be 1000-1300 ft MSL with tops to 1500 ft MSL. Local vis 2-4 miles will occur mainly in the valleys 08Z-16Z Wed with local terrain obscured. Most areas will clear 15Z- 17Z Wed, with VFR conditions prevailing Wed afternoon. Stratus will develop again along the coast Wed evening.

Mountains/Deserts . Mostly clear skies with unrestricted visibility will continue through Wednesday night. Surface west winds will gust 25-35 knots on the desert mountain slopes and through San Gorgonio Pass mainly afternoon/evening.

MARINE. No hazardous marine conditions are expected through Sunday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Excessive Heat Watch from Saturday morning through Monday evening for Apple and Lucerne Valleys-Coachella Valley-San Diego County Deserts-San Gorgonio Pass Near Banning.

PZ . NONE.

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.
