Northwest winds are expected to continue gusting 20 to 25 knots near san clemente island this morning before weakening later today. Offshore flow will develop tonight through Sunday morning. Some northeast gusts could exceed 20 knots near the san diego county coast. A weak coastal eddy may develop once more by early next week.

Area Forecast Discussion National Weather Service San Diego CA 831 AM PST Fri Dec 8 2023
SYNOPSIS
High pressure building over the Great Basin will bring sunny days, clear nights and gusty northeast Santa Ana winds in the mountains, foothills, and valleys. The strongest winds will be on Saturday, but the warmest day will be Sunday, as winds slowly weaken. Fair and dry weather continues next week, with slight cooling Monday into Tuesday.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
The forecast was updated earlier this morning to include some patchy dense fog in the valleys. This was still evident at 8 AM PST, mainly in the I.E. and around Lake Henshaw in San Diego County. High clouds were also visible spreading SE from Central CA. Our offshore sfc pressure gradient from the high desert was increasing this morning, and winds were turning northerly over the San Bernardino Mts in response. Peak gusts were mostly around 30 MPH.
From previous discussion...
Winds gradually turn northerly through the morning, spreading into the Cajon Pass and portions of the Inland Empire by late morning.
Today will be a few degrees warmer west of the mountains as the upper level trough departs and weak Santa Ana winds develop, while the mountains and deserts continue to cool in response to cold air advection from the north.
Surface high pressure builds over the northern Great Basin on Saturday, when Santa Ana winds are expected to peak. This event is mostly gradient driven with little in the way of upper level support, so winds will largely confined to the usual passes/canyons and coastal mountain slopes. Wind gusts in these locations will be around 45-55 mph with isolated gusts to around 65 mph in the favored spots. Winds turn more easterly and weaken on Sunday, diminishing Sunday night. Sunday will also be the warmest day of the week with highs in the mid to upper 70s across many of the coastal areas and western valleys.
A weak trough moves inland across California Monday into Tuesday bringing a brief return of onshore flow and minor cooling. There is some spread in the ensembles regarding the depth of this trough and how quickly it moves out, but this will mainly introduce uncertainty in the temperature forecast as the ensembles remain decidedly dry. Once the trough departs it's back to an upper level ridge and weak Santa Ana winds for the middle of next week. The ensembles all show a more robust low moving in sometime in the 8-10 day timeframe - this time with precipitation! Then again, that's how it looked for this weekend a week ago, and, well, here we are with another Santa Ana.
FIRE WEATHER
Weak north-northeasterly Santa Ana winds will develop later this morning, mainly below the Cajon Pass, where gusts will be around 20- 30 mph. Gradual drying occurs today with minimum humidity around 25- 30 percent in the Inland Empire, and as low as 5-15 percent above 6500 ft elevation. Winds turn more northeasterly-easterly and strengthen tonight into Saturday morning. Strongest winds will be below the Cajon Pass and in the Santa Ana Mountains where gusts 45- 55 mph are expected, with isolated gusts up to 65 mph in the favored locations. Gusts 35-45 mph will occur in and below the San Gorgonio Pass and on the coastal slopes of the San Diego County Mountains.
Relative Humidity will fall to around 10-15 percent on Saturday, except along the immediate coast. Poor humidity recovery is expected each night in the wind prone areas.
Winds slowly weaken Saturday afternoon and continue into Sunday with gusts 25-45 mph, then diminishing Sunday night. Sunday remains very dry with widespread relative humidity of 8-12 percent. Periods of elevated to critical fire weather conditions are expected Saturday into Sunday. A Fire Weather Watch remains in effect for portions of the Inland Empire from 10 AM Saturday through Noon Sunday.
Weak onshore flow returns for Monday and Tuesday with gradual improvement in daytime humidity and better overnight recovery.
