    As of 4:30 PM PDT Tuesday...Occasional rain has been
    falling in the SFO Bay Area while steadier rains have fallen in
    the MRY Bay Area. Radar indicates a break in the action this
    evening as the rain band pushes south of the district. Moist
    unstable air will allow showers to redevelop on Wednesday once
    there is some daytime heating. Thunderstorms are not out of the
    question for Wednesday afternoon but more likely they will be east
    of the district.

    30 kt in the Salinas Valley and 25 kt in the Santa Clara Valley
    will affect SJC and SNS. Winds up to 35 kt above 925 mb could
    produce LLWS tonight. Cigs will continue to be tricky to forecast.
