Area Forecast Discussion National Weather Service San Diego CA 932 PM PDT Wed Jun 3 2020

SYNOPSIS. High pressure will continue to bring hot weather to the lower deserts through Thursday. Inland areas will be cooler Thursday due to increase onshore flow. On Friday, an incoming low pressure system will bring cooling to the entire region, with increased coverage of night and morning low clouds, along with a chance of showers. Gusty west winds will occur in the mountains and deserts on Friday. Gradual warming is expected early next week as the low pressure system pushes east.

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

Evening Update.

Temperatures soared in the inland valleys and deserts this afternoon. Palm Springs and Thermal were the hottest spots, both reaching 115 degrees. Thermal broke its previous daily high temperature record today of 114 degrees from 2016. A few spots in the Inland Empire were over 100 degrees this afternoon.

Low clouds were already beginning to move into coastal areas this evening as a weak coastal eddy spins up. Clouds should make it about 10 miles inland overnight, before clearing out mid to late morning on Thursday.

Temperatures will cool by a few degrees west of the mountains on Thursday due to increased onshore flow, but the lower deserts will remain hot. 500 mb heights, 850 mb temperatures, and the wind pattern over the lower deserts will be nearly the same as today. The only difference is a small influx in low level moisture in the lower deserts, which could pull temperatures down a degree or two from today. Nevertheless, it will still be hot. Given how hot the lower deserts were today, and that there will not be a significant change in the pattern from today, have decided to bump up high temperatures by a couple of degrees in the lower deserts for Thursday. No other changes were made to the forecast this evening.

Previous Discussion from 130 PM.

High pressure aloft will continue over AZ/NM/Chihuahua through Thursday then shift east as the broad deep upper low approaches SoCal. Thursday could have a weak eddy developing, and high resolution models show increasing marine layer moisture, so we should have more low clouds and fog Thu morning near the coast than on recent mornings. It should be cooler west of the mountains Thu, but 850 mb temps near 27 deg C should keep the deserts almost as hot Thu. Everything changes Friday as substantial cooling aloft occurs regionwide, so most locations should be about 10 deg F cooler (some locations more) Fri versus Thu. The marine layer should be deeper Fri and Sat, with widespread night and morning low clouds and likely just partially afternoon clearing near the coast, even with the cooling above the inversion due to the large amount of moisture in the deep marine layer. That moisture could produce a few showers at times, with ensembles and NBM showing the best chances Fri night through Sat morning. Some ECMWF ensemble members show a few hundredths of an inch west of the mountains, but GFS ensembles are mostly a trace, so PoPs should mostly be 25 or less. Even though the upper low will be to our northeast by Sat morning, the long wave trough over the West Coast will dominate and bring the cool weather to the region, with moderately strong west winds in the mountains and deserts, with gusts in windier locations mostly in the 40s to 50 MPH late Friday/Friday evening and slightly weaker 24 hours later. Most model solutions have that low shifting east to the northern Rockies by next Tue with some ridging over the far east Pacific, and temperatures should increase gradually early next week, perhaps becoming above normal in most areas again by Wed after being below normal through about Monday.

AVIATION. 040345Z . OVC010 at the coast spreading 10 miles inland through 14Z Thursday with local vis 5 miles over higher terrain. Clearing between 14Z and 18Z Thursday Elsewhere. SCT080-100 through Thursday.

MARINE. South to southwest winds from a Catalina Eddy Thursday and Friday. Scattered showers are possible Friday evening through Saturday morning with the passage of a trough. Winds shift to the northwest Saturday afternoon behind the trough with northwest winds to 25 kt in the outer waters from Saturday evening through Sunday night, creating hazardous conditions for small craft.

BEACHES. A building long-period southwest swell on Thursday will bring 3 to 5 ft surf Friday through Sunday with occasional sets to 6 feet. Strong rip currents through the period.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Excessive Heat Warning until 7 PM PDT Thursday for Coachella Valley-San Diego County Deserts.

PZ . NONE.
