Area Forecast Discussion National Weather Service San Diego CA 407 AM PDT Wed Apr 24 2024

SYNOPSIS
Gradually cooler through Thursday with a deep marine layer persisting into Friday with patchy night and morning drizzle for the coast and valleys. There will also be periods of gusty southwest to west winds for the mountains and deserts into Friday evening with the stronger gusts to 50 to 60 mph. Then drier with warming, a shallower marine layer, and weaker winds for Saturday through Monday with not much change for Tuesday.

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

.SHORT TERM (Today through Friday)...
A low pressure system from the west will move inland across southern California and northern Baja for late today and tonight.
This will be followed by a faster-moving low pressure system from the northwest moving inland through southern California on Friday.

The marine layer is around 4000 to 4500 feet deep with coastal low clouds extending inland across all of the valleys and onto the coastal mountain slopes. Drizzle has been slower to develop than on Monday night with less coverage of measurable amounts so far.
The greatest coverage has been for coastal areas of central San Diego County inland into the adjacent western valleys.

The HRRR shows greater coverage of light precipitation from drizzle or light rain for late tonight into Thursday morning with the greatest coverage across the coast and valleys in San Diego County. Then patchier coverage for Thursday night into Friday morning. High temperatures will continue to cool for inland areas for today and Thursday with Friday a few degrees warmer for the coast and valleys. With the cooling, high temperatures will be as much as 10 to 15 degrees below average on Thursday for the mountains.

There will continue to be stronger and gusty southwest to west winds for the mountains and deserts into Friday evening with the stronger winds each afternoon and evening. ECMWF ensemble output and calibrated NBM wind guidance continues to show the strongest gusts on Friday afternoon.

.LONG TERM (Saturday through Tuesday)...
A warming trend for Saturday through Monday with not much change on Tuesday with weak high pressure aloft. Winds will be weaker as well. There are some model differences for Monday and Tuesday which would impact the strength of the onshore flow and the depth of the marine layer which is evident in the greater spread of the high temperature forecasts for locations for the coast and valleys versus the mountains and deserts. With the warming, high temperatures would be a few degrees above or below average for most locations on Sunday with high temperatures on Monday a few to around 5 degrees above average.
