Area Forecast Discussion National Weather Service San Diego CA 237 AM PST Mon Dec 11 2023

SYNOPSIS
High pressure over the West will break down today as a weak trough of low pressure dives into the region. This will increase onshore flow today and Tuesday, trying to redevelop a marine layer. This could bring areas of coastal low clouds and fog during the nights and mornings Tuesday into Wednesday. Offshore flow returns with a weak to moderate northeast winds Wednesday in the foothills and some inland valleys. Generally weak offshore flow and dry weather will continue for the rest of the week, with occasional high clouds, warm days and cool nights.

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

Increasing high clouds and pockets of offshore breezes are in the weather picture this morning. Isolated gusts in the foothills are around 20 mph, but winds will be lighter today, a transition day, from offshore flow to onshore. A shortwave will amplify into a low pressure trough that cuts off and moves from around Reno, to Las Vegas and down into Phoenix by Wednesday. Models have been consistent in depicting a robust coastal eddy to develop tonight and continue into early Wednesday in response to this low. This will cool and humidify areas west of the mountains today and Tuesday, and should generate some patchy low clouds and fog.
There's a small chance some true fog will develop Tuesday morning near the coast, but with the rapidly building eddy, any low visibilities would be short-lived at most. The patchy low clouds would spread farther inland Tuesday night into early Wednesday.
Just ready to get flushed out of the coastal basin as offshore winds strengthen Wednesday. The upper low contributes some upper support to the surface gradients, aligning offshore Wednesday.
Strongest gusts appear Wednesday through and below the Cajon Pass area into the Riverside area. Top gusts could reach 40-50 mph in those foothills. As the upper low moves east Thursday, it takes much of the upper support with it, leaving offshore winds primarily driven by the surface pressure gradient. They'll be weaker than on Wednesday, but that pressure gradient will maintain night and morning offshore winds mainly in foothills and adjacent valleys at least into the weekend. Occasional high clouds will drift across the sky this week for some pretty sunrises and sunsets. High temperatures will continue a few degrees above normal. High pressure aloft really amplifies for Friday and Saturday, when high temps could get 5-15 degrees above normal. Dry and calm air will allow nights to stay cool, near normal, for most areas. Of course, nights will be warmer where breezes persist. When will it rain? A very fuzzy picture says probably some time next week. The range of ensemble outcomes includes rain as early as next Monday, or not at all.

AVIATION
110940Z...SCT-BKN clouds at/above 20000 feet MSL with unrestricted VIS through this evening.

MARINE
No marine weather hazards are expected through Friday.

FIRE WEATHER
After a modest recovery in maximum humidity this morning, the minimums will again be in the 10-15% range today. A few easterly gusts up to 20 MPH will blow in the foothills this morning, but overall, winds will be light today, and trending back onshore.
This will bring a much more robust RH recovery later today into Wednesday as a coastal eddy and a marine layer redevelop. Offshore flow will return Wednesday, and continue for the remainder of the week. Portions of foothills and the northern Inland Empire should get some decent gusts Wednesday, but outside of those areas right now it looks like a weak event.

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