INTERIOR CENTRAL CALIFORNIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA 900 AM PST THU FEB 13 2003 MORNING SATPIX SHOWS OUR UPPER TROUGH HEADING FOR THE CENTRAL COAST...WHILE FURTHER SOUTH MUCH OF OUR DISTRICT HAS FALLEN UNDER THE INFLUENCE OF THE SYSTEM/S DRY SLOT...PRODUCING SOME MID LEVEL DRYING AND HELPING TO DECREASE THE COVERAGE OF SHOWERS. THUS...ASIDE FROM SCT-BKN AC...DO EXPECT TO SEE ENOUGH SUNSHINE FILTERING THROUGH TO BOOST TEMPERATURES HIGHER THAN CURRENT PACKAGE SUGGESTS AND WILL THUS UPDATE THE ZONES TO ACCOUNT FOR THIS. MORE IMPORTANTLY...THE INCREASE IN SURFACE TEMPERATURES WILL FURTHER DESTABILIZE THE LOWER ATMOSPHERE. MESOETA H7 PROGS INITIALIZE A SATURATED AIRMASS ALONG WITH SOME LIFT AT THIS LEVEL...BUT GROUND TRUTH SUGGESTS THAT WITH MORE SUNSHINE...STABILITY PARAMETERS WILL BE MORE FAVORABLE FOR CONVECTION THAN MODELS HAVE KEYED IN ON. THE 12Z ASSESSMENT FROM SPC DEPICTS THE SOUTHERN FRINGES OF THE CWFA IN THE GENERAL THUNDERSTORM CATEGORY..ALTHOUGH IT SEEMS THAT THE NORTHERN PORTIONS OF OUR FORECAST AREA ARE CLOSER TO THE DYNAMICS ASSOCIATED WITH THE UPPER LOW. AS IT STANDS...12Z MESOETA PROGS PAINT THE ENTIRE CWFA WITH NEGATIVE LI/S BY 21Z...WITH SURFACE BASED CAPES APPROACHING 300 J/KG OVER MERCED COUNTY. A VORT MAX IS ALSO PROJECTED TO BE RIDING INTO THIS SAME AREA TOO. FINALLY...MSAS OBSERVATIONS FROM 15Z SHOW A DISTINCT SURFACE MOISTURE CONVERGENCE/DIVERGENCE GRADIENT BETWEEN FRESNO AND MODESTO. MODIFIED MODEL SOUNDINGS WHICH INCLUDE THE EXPECTED HIGHER SURFACE TEMPERATURES FOR KMCE SUGGEST LI/S OF -3 AND CAPES ABOVE 500 J/KG. WITH WET BULB ZEROS RUNNING 7000 FT MSL...HAIL THREAT SHOULD BE MINIMAL. TRANSLATION...THINK CONVECTION IS A GOOD BET ACROSS THE AREA TODAY...ALTHOUGH IT SHOULD BE A STRUGGLE TO REACH SEVERE CRITERIA GIVEN LESS THAN FAVORABLE HELICITY AND HIGH WET BULB ZEROS. GOING FORECAST HAS MENTION OF THUNDER FOR MOST ZONES BUT WILL BEEF UP WORDING ACROSS KERN MOUNTAINS. WILL SHORTLY UPDATE ZONES TO MAKE CHANGES PREVIOUSLY DISCUSSED. BURGER .HNX...NONE.
