SATELLITE AND KDAX BOTH SHOW CONVECTION GOING PRETTY GOOD ALONG THE
COAST INTO THE WESTERN FOOTHILLS. SPOTTER IN CORDELIA REPORTED OVER
.5 INCHES OF RAIN FOR THIS MORNING WITH MOD TO HEAVY RAINSHOWERS IN
PROGRESS.  MAIN PRECIPITATION BAND ASSOCIATED WITH SURFACE FRONT NOW
WELL INTO THE SIERRA WITH BLU DURING PREVIOUS TWO HOURS PICKING UP
AROUND .2 INCHES PER HOUR.  MODELS ALL BRING MAIN UPPER LEVEL SYSTEM
OVER VALLEY AREA AROUND 00Z TODAY.  LOOKING AT RAMSDIS TIMING FAIRLY
GOOD.  MAIN THOUGHTS ON THUNDERSTORMS CENTERS AROUND WHETHER WE WILL
GET A BIT OF CLEARING THIS AFTERNOON TO HELP DESTABILIZE THE LOWER
LAYERS OF THE ATMOSPHERE BEFORE MAIN VORT MAX SLIDES ON THROUGH.
PLAYING WITH SHARP THIS MORNING NEED TO REACH LOW 60S TO GET REAL
GOOD INSTABILITY. CURRENTLY SITTING IN MID TO UPPER 50S.  WATER VAPOR
LOOP DOES SHOW DRY SLOT ALONG THE COAST...THOUGH IS BEING OVERTAKEN
BY UPSTREAM VORT MAX.  ANYWAY WILL PLAY IT SAFE AND KEEP POSSIBILITY
OF TRW IN ALL FORECASTS THROUGH THIS EVENING.

PRECIPITATION TO END RAPIDLY LATE THIS EVENING AFTER MAIN TROF MOVES
THROUGH.  ALL THREE MODELS ARE AGAIN BRINGING BEAUCOUP MID/UPPER
LEVEL MOISTURE OVER FORECAST AREA ON WEDNESDAY...THOUGH AFTER THIS
PAST WEEKEND AM HESITANT TO GO MOSTLY CLOUDY SO WILL STAY WITH PARTLY
CLOUDY ATTM.
