Area Forecast Discussion
National Weather Service San Diego CA
930 PM PDT Mon Oct 25 2021

Dry weather will prevail Tuesday through the weekend, with a warming 
trend Tuesday through Thursday. Weak northeasterly winds will occur 
Wednesday through Thursday. Onshore flow will return next weekend, 
spreading cooling inland and bringing a return of night and morning 
coastal low clouds and fog.



Evening Update:

The weakening atmospheric river storm system brought a widespread 
and mainly beneficial rainfall to the SoCal region. The rain has 
tapered off with the last bands of rain now moving through 
Southeastern San Bernardino County near the Arizona border. There is 
still the potential for a few showers to come off the ocean into 
mainly San Diego County and Southern Orange County for a few more 
hours. The gusty winds have also abated. The storm total rainfall 
amounts and wind reports are available on our website and social 
media feeds. 

Previous Forecaster Discussion remains valid, issued at 2 pm PDT: 

Fair weather will prevail starting late tonight as a broad area of 
zonal high pressure over the east Pacific gradually shifts east into 
the western US. Tuesday will be 5-10 deg F below normal, but 
temperatures will recover to near normal Wednesday and 5-10 deg F 
above normal Thursday, with some lower 90s possible in warmest 
valleys based on some of the ENS contributors to MOS. The lower 
deserts will likely be above 90 then as well. The high will weaken 
over the weekend as some sort of troughing and/or upper low moves by 
to the north, though models are inconsistent with details. Most 
likely that will result in a cooling trend then and early next week, 
with a return of marine layer stratus near the coast. 



260335Z...Coasts/Valleys/Coastal Mountain Slopes...SHRA across San 
Diego County will continue to move east-southeast and dissipate 
through 06Z. CIGS locally down to 1500 ft MSL with viz 3-5 SM in 
SHRA. After 06Z, SCT-BKN cloud layers 2500-5000 ft MSL gradually 
clearing overnight. Coastal mountain slopes remaining obscured 
through about 10-12Z. Mostly clear with unrestricted vis after 12Z 

Desert Mountain Slopes/Deserts...W-NW winds with sfc gusts kts 25-35 
kt continuing through 10Z and gradually weakening through the 
remainder of the morning. STG up/downdrafts, rotors, and LLWS 
possible over/east of the mountains, including VCTY KPSP. Otherwise 
mostly clear with unrestricted vis through Tue evening.


Northwest winds gusting 20-25 kt and seas 6-12 ft will generate 
conditions hazardous to small craft. A Small Craft Advisory is in 
effect through early Tuesday morning. Conditions will gradually 
improve through the day Tuesday. No hazardous marine weather is 
expected Tuesday afternoon through Saturday.


A large, long period west swell and a 2 ft long period south swell 
will combine to produce high surf and dangerous swimming conditions 
through early Wednesday. Surf of 5 to 8 feet, with local sets to 10 
feet in southern San Diego County and strong rip currents likely. A 
High Surf Advisory is in effect through early Wednesday morning.


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