Area Forecast Discussion
National Weather Service San Diego CA
934 PM PST Thu Feb 25 2021

Friday will be a sunny, mild day. A Catalina Eddy will form over the 
coastal waters Friday and it will spin up low clouds near the coast 
Friday night into Saturday. Saturday will be a little cooler as the 
marine layer deepens and the onshore flow increases ahead of an 
approaching trough. After the trough passes Saturday evening, strong 
northeast winds will once again impact the mountains and foothills 
through Sunday. Monday will be dry. There is a chance for light 
precipitation Tuesday and Wednesday. 



Evening Update: 

The Santa Ana wind event was a strong one, as highlighted on the 
wind report issued earlier this afternoon, and headlined on social 
media and our website. Otherwise quiet weather will be expected for 
the remainder of tonight, and into Friday. Onshore flow late Friday 
will bring in marine enhanced air to the coastal strip and patchy 
fog. No changes were necessary this evening. 

Remainder of the previous forecast discussion, issued at 240 PM PST:

Santa Ana winds peaked this morning with gusts above 70 mph at the 
wind prone areas in San Bernardino and Orange County Mountains. 
Marshall Peak in the San Bernardino Mountains had a gust to 98 mph, 
and CSU San Bernardino had a gust to 81 mph. Several big rigs were 
overturned on the I-15 and I-210 below the Cajon Pass. Winds also 
gusted to 58 mph at Desert Hot Springs last night.

The winds will decrease this afternoon as gradients weaken. Friday 
will be a little warmer than today in most areas. A Catalina Eddy is 
forecast to spin up Friday night which will deepen the marine layer 
and spread low clouds and fog into the coastal zones Saturday 
morning, perhaps as far inland as the western San Diego Valleys. 
Saturday will be a cooler day with lower heights and stronger 
onshore flow associated with a fairly strong inside slider 
racing across the Great Basin and into Arizona Sunday.  

Gradients turn quickly offshore Saturday night and that will bring 
in another round of Santa Ana winds Saturday night and Sunday. This 
Santa Ana event won't be a strong today's, but it will still 
generate northeast winds from 40-60 mph in the mountain and 
foothills, and that may require a High Wind Watch or Wind Advisory. 
Sunday will be a colder day is all areas. Marine layer clouds and 
fog in San Diego County Sunday morning will slowly erode as the 
drier offshore flow make its way southwestward. 

Monday will be a dry and warmer day with generally sunny skies and 
weaker offshore flow. 

The Tuesday and Wednesday outlook is a murky as it was yesterday. 
All of the deterministic and the ensemble runs continue to show a 
large model spread next week. The variability ranges from dry and 
warm with ridging (ECMWF) to wet and cool troughing (GFS). The 
Canadian model is also supporting and cooler, wetter solution. 
Forecast confidence remains very low for this time period. 


260400Z...Local breezes with gusts 20-30 MPH this evening across the 
mountains will continue to subside through tonight. Otherwise, 
mostly clear with VFR conditions through Friday. 


No hazardous marine weather expected tonight through Saturday. 
Northeast winds expected starting early on Sunday morning through 
Sunday night with some gusts over 20 knots possible.


Skywarn activation will not be needed Friday.
