KEEPING AN EYE ON SAN JOAQUIN VLLY CONVECTION...THUS FAR STAYING
TAME WITH ONLY SMALL HAIL REPORT JUST NORTH OF THE CWA NEAR TURLOCK
EARLY THIS AFTN. A VERY POTENT SHORT WAVE IS RAPIDLY DRIVING SSE AND
PULLING THE ENTIRE UPPER SYSTEM WITH IT. THIS WAVE WILL BE THE BIG
FOCUS FOR PRECIP TONIGHT AND TUE AS IT COMES AROUND THE BASE OF THE
TROF AND STRIKES LAND NEAR THE L.A. BASIN. THUS THE CONCERNS FOR
SIGNIFICANT PRECIP WILL SHIFT SOUTH FOR TONIGHT/TUE...WITH PROXIMITY
OF UPPER LOW AS IT SLOWS AND TRACKS ACROSS SOCAL. ONLY MODERATE
CONFIDENCE WITH FCST...AS TRACK IN THE NEXT 24 HOURS COULD SHIFT
FROM PROGGED POSITIONS AND CHANGES WILL HAVE SIGNIFICANT IMPACT IN
THE SOUTH. WILL EXPIRE WINTER STORM WARNING EVERYWHERE AND POST A
SNOW ADVISORY FOR THE KERN AND TULARE MTNS. THESE AREAS...ESPECIALLY
THE TEHACHAPI MTNS...NEED TO BE WATCHED CLOSELY FOR POSSIBLE UPGRADE
TO WINTER STORM WARNING. FOCUSED LIFT ASSOCIATED WITH IMPRESSIVE
SHORT WAVE ENERGY WILL BRING BEST QPF POTENTIAL LATER TONIGHT AND
DURING ALL OF TUES. IN COORD WITH VEGAS...SHOULD SEE UPSLOPE ESE
FLOW ALONG SIERRA CREST WHICH COULD BRING A SHADOWING EFFECT NORTH
OF KERN MTNS.

IN THE EXTENDED...AFTER SYSTEM FINALLY EXITS WED...LOOKING FOR UPPER
RIDGE TO BRING DRY CONDS THU-SAT. LOW CONFIDENCE IN MEDIUM RANGE FOR
THIS WEEKEND...WITH A WEAK MAJORITY OF MODELS GIVING US A CHANCE OF
PRECIP RETURNING BY SAT NIGHT/SUN. INDICATING CHC SUN AND MON FOR
THE TIME BEING.

.HNX...SNOW ADVISORY THROUGH TONIGHT AND TUESDAY FOR KERN COUNTY AND
       TULARE COUNTY.
