Area Forecast Discussion National Weather Service San Diego CA 151 PM PDT Thu Apr 25 2024

SYNOPSIS
Gusty westerly winds; periods of drizzle or light rain west of the mountains; and cooler conditions are expected through Friday. A deep marine layer will result in night and morning low clouds throughout much of the coastal basin through Friday. The marine layer will become shallower into the weekend. A gradual warming is expected over the weekend into early next week.

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

Visible satellite at 130 PM this afternoon was showing widespread cloud coverage across the coastal basin. Clear skies were prevailing in the mountains and deserts. The marine layer will remain deep into Friday as a low pressure system digs south into the Great Basin.
This will keep the atmosphere unsettled, with periods of passing shortwaves moving through the mean flow ahead of the core of the system. The passing shortwaves are expected to generate areas of scattered light showers or drizzle as they interact with deep marine layer moisture tonight into early Friday morning. As the core of the low digs into the Great Basin Friday afternoon and evening, periods of light showers are expected to develop. Coast and valley areas in San Diego county as well as the coastal mountain slopes are the most likely places to see a shower. Most areas will see 0.05 inches of rain or less, but a few locations may accumulate up to 0.15 inches if showers train across that particular area. 0.10 to 0.35 inches of rain are possible in the mountain foothills. Light snow accumulations are possible above 7000 ft Friday evening.

Periods of gusty westerly winds will continue over the mountains and into the deserts through Friday night. Peak gusts for this afternoon into early Friday morning will be mostly 50 to 60 mph on the desert mountain slopes. Gusts 40 to 50 mph possible in the deserts. Local gusts up to 70 mph possible through the San Gorgonio Pass near Whitewater. Gusty winds will continue for Friday afternoon into early Saturday. There is a potential for more widespread coverage of stronger wind gusts on Friday as a low pressure system moves into the Great Basin and east into the Four Corners region. Peak Gusts of 50 to 65 mph are expected on the desert mountain slopes. Gusts in the deserts will peak at 40 to 50 mph. There will also be the potential for gusts 70 to 75 mph in wind prone locations like through the San Gorgonio Pass.

Widespread below average high temperatures are expected tomorrow and Saturday. By Sunday, highs will warm to near average, with some locations still a degree or two cooler than average for this time of year. Further warming is expected into early next week. By the middle of next week, some uncertainty develops in the upper level pattern, with some ensemble solutions showing troughing while others maintain a weak ridge. This introduces uncertainty into the temperature forecast, with the potential for cooler conditions to return. This uncertainty also impacts the depth of the marine layer.
Current forecast follows NBM with a few degrees of cooling on Thursday with a shallower marine layer for early next week, slowly deepening into the middle to end of next week.
