Weather for Sausalito Sailing charters this week. Temperatures have soared this morning in part due to strong northerly winds, clear skies, and a mixed out marine layer. For the short term forecast, bumped forecast high temperatures up by a few degrees across the North Bay Valleys and Santa Clara Valleys where more significant warming already occurred this morning. Temperatures are already in the low 80s across the North Bay with highs set to reach the upper 80s across northern portions of Sonoma and Napa. Offshore winds have started to ease across the North Bay and East Bay with only a few locations in the higher elevations still gusting above Wind Advisory Criteria. Thus, the Wind Advisory was allowed to expire as of 2 PM with the winds expected to continue trending downwards. Synoptically, the cut-off low to our southeast has started to weaken and is shifting further east into the Intermountain West while high pressure builds in more firmly over California. At the surface, the KSFO-KACV (Humboldt County) pressure gradient shows that our North-South gradient peaked around 3AM this morning around -9.50 hPa (strongly northerly) and has diminished to -6.40 hPa as this afternoon. This gradient is forecast to ease to around -1.0 hPa (weakly northerly) by early Tuesday morning. Accordingly, gusts will continue to ease through tomorrow morning with gusts up to 30 mph expected this evening diminishing to around 15 to 20 mph by tomorrow morning.
