SAN FRANCISCO (KCBS Radio) -- A deep marine layer. A strong onshore flow. An upper level low-pressure system.

Whatever the meterological terms are, the results are unmistakable: a coninuing spell of cool, gray, damp weather for the Bay Area.

Tuesday temperatures ran from 7 to 10 degrees below normal for the date in locations from San Jose to San Francisco to Concord. Wednesday's forecast offers little expectation of change, For example, the historical average high for Concord on May 23 is 78, but the forecast calls for an afternoon maximum of 67.

The soupy weather could help ease concerns about fire season, as it has brought measurable precipitation to a number of Bay Area locations.  One weather station on Rocky Ridge, at elevation 2020' west of Danville, recorded .20" of moisture in a 24-hour period from Tuesday morning to Wednesday morning.

The forecast calls for cool, gray weather to last through ther rest of the work week. In fact, it could get even worse: a cold front from the Gulf of Alaska is expected to dive through the Bay Area Thursday into Friday, bringing a chance of showers and colder air. Warmer conditions are forecast for the Memorial Day weekend.
