Slight chance of thundershowers tonight

Most of us here on the Central Coast have noted the clouds overhead today. NOAA has a forecast discussion of interest to us.

“TRACE AMOUNTS OF PRECIP HAVE BEEN REPORTED AT THE MONTEREY CLIMATE STATION…NEAR HOLLISTER AND IN LIVERMORE SO FAR. NO LIGHTNING HAS BEEN DETECTED YET…BUT MAINLY DUE TO FIRE WEATHER CONCERNS A SLIGHT CHANCE WAS ADDED TO THE HILL ZONES FROM THE EAST BAY SOUTHWARD THROUGH MONTEREY/SAN BENITO COUNTY FOR THIS EVENING.

LATEST RADAR RETURNS AND EXAMINATION OF VISIBLE SATELLITE SUGGESTS THAT NEXT BAND OF MOISTURE CURRENTLY WEST OF BIG SUR COULD BE A LITTLE MORE UNSTABLE. FOR NOW HAVE LEFT ANY SHOWER/T-STORM CHANCES IN THE 15-20% RANGE FROM THE EAST BAY SOUTHWARD THROUGH THIS EVENING WITH ANY CHANCES ENDING BY ABOUT 12Z AS UPPER TROUGH AXIS PUSHES MOISTURE AXIS TO OUR EAST. SO WILL MONITOR PRECIP TRENDS THIS EVENING WITH DRY FORECAST FOR SUNDAY.”

And an 8:45 update:
ISOLATED THUNDERSTORMS HAVE BROKEN OUT…A FEW NEAR THE DELTA LATE THIS AFTERNOON…AND ONE NEAR HALF MOON BAY EARLY THIS EVENING. GRIDS AND VARIOUS PUBLIC AND FIRE WEATHER TEXT
FORECASTS HAVE BEEN UPDATED THIS EVENING TO BETTER REFLECT CURRENT WEATHER CONDITIONS. ALSO…BASED ON RADAR AND SATELLITE DATA…IT APPEARS THAT ISOLATED SHOWER AND THUNDERSTORM ACTIVITY MAY LAST PAST MIDNIGHT AND SO HAVE EXTENDED RAINFALL CHANCES THROUGH THE NIGHT.
