.UPDATE...INCLUDED SLIGHT CHANCE OF THUNDER NORTH OF TULARE COUNTY

.DISCUSSION...
CONVECTION STARTING TO BREAK OUT THIS MORNING ACROSS THE SIERRAS
NORTH OF KINGS CANYON. UPPER LEVEL VORT IS STILL OFF THE COAST AND
IS EXPECTED TO MOVE IN LATER THIS AFTERNOON. HAVE INCREASED POPS
AND INTRODUCED THUNDER TODAY AS VORT MOVES THROUGH. NO OTHER
CHANGES TO CURRENT FORECAST AND ALL WATCHES AND WARNINGS ARE STILL
IN PLACE.

...PREVIOUS EXTENDED DISCUSSION...

TSTM THREAT FOR THE VALLEY AND LOWER FOOTHILLS APPEARS MINIMAL
FOR SUN AFTERNOON AS H5 TEMPS BEGIN TO RISE. HOWEVER...AS H5
TEMPS RISE...PARTIAL AFTERNOON CLEARING COULD STILL PRODUCE SOME
FAIRLY STEEP LAPSE RATES. ANY THUNDERSTORMS THAT DO DEVELOP WOULD
LIKELY HAVE SOME GUSTY WINDS ASSOCIATED WITH THEM IN
UNI-DIRECTIONAL FLOW.

BEYOND SUN...GFS AND THE EURO SHOW RIDGING IN THE EAST PAC ROUGHLY
ALONG 140W. SHORTWAVE TROFS MOVING THRU AND OVER THE TOP OF THE
RIDGE FROM TIME TO TIME ARE FORECAST TO MAINLY DIG SE ACROSS THE
NRN AND CENTRAL ROCKIES AS SLIDERS...AND HAVE VERY LITTLE IMPACT
ON CENTRAL CA. TEMPS SHOULD REBOUND TO NEAR NORMAL TUES...THEN A
FEW DEGS ABOVE AVERAGE FOR THE REMAINDER OF THE WEEK.
