    Okay, enough already!

    I can't tell you how many times I've heard that already and the many more dirty looks I get at the Safeway checkout line in San Ramon these days.  The words, "I'm only the messenger" aren't holding up as well as they used to.

    As you're well aware our weather is normally much warmer and not quite as wet as the weather we've seen over the last two weeks.

    Thanks to our friend Jan Null, CCM (Golden Gate Weather Services) we now have a better idea of just how long its been since San Jose has been this chilly this late in the year.

    Null says San Jose's daytime highs were about 7 degrees below average for the month, good enough for temps that haven't been this cool in May since the 1930s.

    San Jose also didn't get above 82 degrees that puts it in the company of 1917 as the last time we had a month of May where we couldn't climb above 82 degrees.

    June Showers Before Summer Sizzle

    [BAY] June Showers Before Summer Sizzle
    A late season storm will drop a chance of showers (!) across the Bay Area late Thursday in the North Bay and across the central Bay Area midday Friday. Rain totals may approach 1"+ for areas Mendocino County/Lake County northward while the front pretty much falls apart as it nears San Francisco. There's plenty of moisture out there and provided we get enough lift even with a decaying frontal boundary - we ought to see some showers north of SF for Friday. The weekend will trend drier and a little warmer as another weather system skirts by to the north. By Monday and Tuesday high pressure should take hold boosting inland temps into the 80s and 90s.

    The culprit has been an unusually strong trough or dip in the jet stream hung up over the West Coast since mid-May.  We'll see another chance for more showers late Thursday into Friday.  (Seriously... June showers).  The best odds for finding rain looks to stay mainly north of the Golden Gate however.

    Fans of heat rejoice as the extended forecast calls for the first potential 'heat wave' of the year to get ramping up around Sunday.  We may hit some 90s in spots Monday through Tuesday before, yet, another trough possibly drops in on us late next week.
