0318 PM CDT SUN AUG 02 2009
AREAS AFFECTED...SCNTRL/SWRN ORE AND EXTREME NRN CA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 022018Z - 022215Z
TSTMS WILL INCREASE IN INTENSITY/NUMBER THROUGH THE LATE AFTN WITH
AT LEAST ISOLD DMGG WIND GUSTS AND LARGE HAIL.
WATER VAPOR IMAGERY SHOWS THE NEXT IN A SERIES OF MID-LVL WAVES
ROTATING NWD INTO NRN CA AT 20Z. DOWNSTREAM AIR MASS ACROSS NRN
CA/SRN ORE CONTINUES TO DESTABILIZE AS TEMPERATURES WARM THROUGH THE
80S AMID PWATS IN EXCESS OF 25 MM. TCU/CBS HAVE ALREADY BEEN
PERCOLATING ALONG THE MOUNTAINS...ESPECIALLY IN MODOC/LAKE COUNTIES
SINCE 18Z. EXPECT THAT TSTMS WILL CONTINUE TO GROW UPSCALE AND/OR
DEVELOP NWWD WITH TIME AS THE SHORTWAVE TROUGH ROTATES ACROSS THE
REGION.
PRESENCE OF 30-50 KTS OF H5-H25...FAIRLY UNIDIRECTIONAL SELY FLOW
WILL CONTINUE TO BOOST DEEP LAYER SHEAR ON THE ORDER OF 30-35 KTS.
THIS WILL BE MARGINALLY SUFFICIENT FOR SPLITTING SUPERCELLS WITH
LARGE HAIL...SIMILAR TO SATURDAY/S ACTIVITY. OTHERWISE... EVOLUTION
INTO MULTICELL CLUSTERS/SHORT LINE SEGMENTS GIVING SVR WIND GUSTS
WILL BE MORE LIKELY.
