Area forecast discussion 
National Weather Service San Francisco Bay area
947 am PST Wednesday Feb 10 2016

Synopsis...dry pleasant weather will continue through the rest
of the week. Large westerly swell will begin to impact the coast
Thursday raising the risk of sneaker waves at area beaches.

&&

Discussion...as of 9:34 am PST Wednesday...high clouds are
pushing into the forecast area this morning as a storm system
continues to slowly move towards the Pacific northwest. Generally
light winds at the surface are expected to increase out of the
west this afternoon as the sea breeze becomes established. The
combination of the high clouds moving into the area and the
afternoon sea breeze will help to keep temperatures a little
cooler than observed yesterday...closer to seasonal norms.

The 0000z European model (ecmwf) and 1200z gfs40 have initialized well with the
current synoptic weather pattern and remain in good agreement
through at least the beginning of next week. Over the past few
model runs...model solutions have been trending drier over our
forecast area. At this point we are forecasting a high confidence
dry forecast through the weekend. The next possibility for
precipitation appears to be next Wednesday as a storm system
begins to impact the West Coast.
