.UPDATE...
SHORTWAVE AND REMNANTS OF MCS NOW MOVING THROUGH THE MID STATE.
SCT CONVECTION CONFINED TO THE SE HALF OF THE CWA WHILE THE NW
HALF IS VIRTUALLY PRECIP FREE. MODELS LEANING TOWARD A DRIER
PATTERN FOR TODAY AS DISTURBANCE PULLS OFF TO THE EAST. BY
AFTERNOON...A DEEPER DRIER LAYER WILL WIN OUT AND CONVECTION WILL
BE LIMITED.

NUMERICALLY...MET GUIDANCE DOING A BETTER JOB WITH THE MCS NW FLOW
REGIME WHICH TENDS TO BE VERY TRICKY...TO SAY THE LEAST. WITH
THAT BEING SAID...MET GUIDANCE DOES PULL POPS DOWN TO THE ISOL
RANGE FOR THE AFTERNOON PERIOD.

FOR TODAY...I WILL LOWER POPS FROM NW TO SE...AND EVENTUALLY ISOL
POPS WILL COVER THE ENTIRE CWA FOR THE AFTERNOON. ONLY CHANGE FOR
NOW WILL BE TO LOWER NW SECTIONS. PARTLY CLOUDY WORDING IS STILL
GOOD AS WE WILL BEGIN TO SEE MORE SUNSHINE AS THE DAY GOES ON.

WONT CHANGE HIGH TEMPS FOR NOW. ONCE SUNSHINE APPEARS...QUICK
WARM UP MAY OCCUR.
