Wind Recipe:1- The Cut-Off Low ≈ 18,000 feet continues to block most of the NW ocean winds while enhancing:a. Coastal eddies. b. WSW ocean winds. c. Strong ≈ 1000 feet aloft WSW turbocharges surface wind at Sherman/TI/N. Tower. d. broken atypical marine layer. d. Cool weather. 2- The WSW ocean winds accelerate through gaps in…
Saturday’s Wind Recipe: Rio Daze is milder but solid!1- The North Pacific High FINALLY gets rid of that eddy inducing ridge into far Northern California. So Eddy DIES! 2- So our ocean winds turn from SSW to WNW and curve to almost every site in the Bay Area as… 3- The Central Valley low retreats…
For nearly two weeks, a persistent counter-clockwise eddy off the coast of San Francisco has been the dominant meteorological feature, overriding the typical summer wind patterns of NW ocean winds and funneling strong southwesterly winds through the Golden Gate and into much of the San Francisco Bay. This unusual and prolonged event is the result…
I hope every one saw this notice in the AM forecast: “Be ready for a chance of abrupt fades, especially on Peninsula” and Crissy was really up and down as forecast. he strong winds just aloft mentioned in the forecast today form ripples as they hit higher hills.

Area. 2- The eddy spins all day as it gains southerly support from a low-pressure that extends up to ≈…
A massive eddy off San Francisco to Jalama divert the North Pacific High’s surface NW winds away from the Central California coast all day. However, these eddy winds help the Lopez and maybe Isabella winds. The eddy you see from north of San Francisco eddy to past Jalama diverts the North Pacific High’s surface NW…

Way back in June 19, during a very strong NW wind pattern, I was asked on Facebook how long the NW ocean winds would last. Here is my Facebook reply: Now, over a week later here is my forecast for June 28. It is not polite to brag. But sometimes you just can’t resist in…
June 20 & 21 the Bay Area saw a significant high-wind event, marked by a notable absence of the typical June Gloom marine layer clouds and ferocious surface gusts exceeding 50 knots. These winds had the clear signature of an exceptionally powerful and unusually low-altitude California Coastal Low-Level Jet (CLLJ). The powerhouse behind any wind…
Very EARLY GUSTY low to mid 20’+ ENTIRE coast & Bay mid-Golden Gate south past 3rd. Ave. + Sherman, Rod & Gun.
