Area Forecast Discussion
National Weather Service San Diego CA
900pm PDT Tuesday September 27 2022

Synopsis
Hot conditions will continue across the region through tomorrow. Increasing moisture will lead to a slight chance for showers and thunderstorms on Wednesday across the mountains, High Desert and eastern portions of the inland valleys. Greater cooling is expected for Thursday through the weekend.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
Evening Forecast Update:

No updates were needed this evening. Low clouds will begin to form towards midnight near the coast and spread inland a few miles through Wednesday morning.

Previous Discussion (issued at 155pm PDT):

For Wednesday, increasing moisture will lead to a slight decrease in temperatures by a degree or two region-wide, though highs will remain well above seasonal averages. This will continue to lead to moderate to locally high heat risk across the region. Scattered showers and thunderstorms will be possible through the afternoon, mainly across the mountains, High Desert and eastern portions of the inland valleys. The main threat will be frequent lightning and gusty winds, though heavy rainfall leading to local flooding will be possible.

The ridge will weaken on Thursday as an upper-low moves through the Pacific Northwest. Onshore winds and drying conditions are anticipated for Thursday through the weekend, allowing for cooler temperatures. By Saturday, high temperatures are expected to be near or slightly below average west of the mountains, and slightly above in the deserts.

The 12z ECMWF (European Centre for Medium-Range Weather Forecasts) Ens Mean shows ridging moving into the western United States for the second half of the weekend, with positive height anomalies returning to Southern California Sunday night into Monday. This may lead to slight warming early next week.

Marine
No hazardous marine weather is expected through Saturday.

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