|

Nationwide we are having issues with our forecast portal today so the forecast may not be available via normal link. So I am posting Bay Area forecast here:
The winds are WSW 28g28 at Tracy near the terminus of the Altamont Pass with some nearby sensors seeing gusts near 50. This confirms that the maximum pressure gradient from the ocean to the Central Valley is directed towards the Stockton area. (Actually, once all this wind passes over the greater Stockton area it "feels" the pressure gradient towards Bakersfield and towards Redding and heads north and south but that all happens way after it has passed over all of our launch sites.) All this suggests that my forecast from last night only needs some fine tuning.
Despite an approaching storm the NPH's NW winds stay glued to the California coast. Strong W to W winds at ≈1000 feet aloft (975MB level) aloft act to accentuate the W flow and marine layer clouds through the Golden Gate, Hwy. 92 Gap and over the Peninsula coast range towards Stockton which favors strong WEST wind focusing:
1. Straight from the Golden Gate gap to Berkeley to near RaceTrack.
2. Straight through the Petaluma and Nacasio gaps past Rod & Gun and Benicia to Sherman Island.
3. Hitting DL to Natural Bridges to PP to Moss Landing to Pacheco Pass to San Luis Res. and the Forebay.
4. W. wind and fog over the Peninsula coast range and disrupting the launch winds except for Candlestick.
<b>Special Sites:</b> Dillon (if we get clearing) and Rod & Gun blow hard.
