NWS Forecaster Discussion
887 fxus66 kmtr 200004 afdmtr Area forecast discussion National Weather Service San Francisco Bay area California 300 PM PDT Sat Jul 19 2008 Discussion...as of 3:00 PM PDT Saturday...satellite imagery shows the coastal stratus to be eroding from the north with some clearing north of Point Reyes. The eddies are still apparent in the Monterey Bay and near Point Piedras Blancas. Slight cooling is occurring across the northern half of the County Warning Area with slightly warmer temperatures across the south. The marine layer depth has been steadily rising through the day and is now around 1800 feet. The surface pressure gradients have increased as well with 3.1 mb between sfo and SAC... and 4.1 mb from acv to sfo. Even though the skies are clearing from the north...current thinking is that the clouds will reform over the ocean this evening with low clouds and fog spreading well inland again tonight as an upper level trough deepens just off the West Coast. This trough is expected to bring on a cooling trend over the next few days with an increasing marine layer and enhanced onshore flow. The upper trough is prognosticated to cut off into an upper low west of the northern California coast by Sunday night. This upper low then is forecast to move east across the extreme northern part of the state on Monday followed by weak ridging by the middle part of the week. Zonal flow across northern California will keep a typical Summer weather pattern for our district through the remainder of the forecast period. Near-normal temperatures with night and morning stratus episodes are expected. && Aviation...as of 5:00 PM Saturday...sf Bay area...stratus is clearing off the coast as northerly gradients increase. Stratus expected to reform later tonight but will stay out of sfo and Oak until around 05z. Winds holding under 20 knots at sfo. Approaching upper trough will deepen the marine layer resulting in later burnoff Sunday. Monterey Bay area...clouds have stuck to southern mry Bay all day today and should stay in over mry and sns through Sunday morning. && Mtr watches/warnings/advisories... ... Bay pt Arena to Pigeon Point. $$ Public forecast: Anderson aviation/marine: Larry/west pi National Weather Service on the web at weather.Gov/sanfrancisco
