AREAS AFFECTED...HIGH DESERTS OF SERN CA AND SWRN NV

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 052029Z - 052200Z

ISOLATED DAMAGING WIND GUSTS WILL BE POSSIBLE AS CONVECTIVE LINE
MOVES ACROSS THE MOJAVE DESERT OF ERN KERN...NRN/WRN SAN BERNARDINO
AND SRN INYO COUNTIES OF SERN CA THROUGH 23Z. THREAT FOR DAMAGING
WINDS MAY SPREAD INTO THE HIGH DESERT OF SWRN NEVADA AFTER 23Z. 

LATEST RADAR IMAGERY SHOWS SEVERAL BANDS OF CONVECTION MOVING ACROSS
SERN CA. ONE BAND WAS MOVING THROUGH THE OWENS VALLEY...WITH ANOTHER
STRONGER BAND SUPPORTED BY A COLD POOL MOVING THROUGH THE SRN SIERRA
NEVADA/TEHACHAPI MTNS. A WELL DEFINED GUST FRONT THAT MOVED THROUGH
BFL IN THE LAST HOUR SHOULD AID IN ADDITIONAL REDEVELOPMENT ALONG
THE LINE/S LEADING EDGE ALLOWING CONVECTION TO REMAIN STRONG AS IT
CROSSES INTO THE HIGH DESERT. THE THERMODYNAMICS DOWNWIND OF
CONVECTION OVER THE HIGH DESERT WAS CHARACTERIZED BY DEEPLY MIXED
ENVIRONMENT UP TO AROUND 600 MB. RECENT FCST SOUNDINGS MODIFIED FOR
20Z OBSERVATIONS INDICATE AROUND 750 J/KG OF MUCAPE ABOVE THE DEEPLY
MIXED BOUNDARY LAYER. GIVEN THE STRENGTH OF THE AMBIENT GRADIENT
WIND FIELDS AND POTENTIAL FOR CONTINUED ORGANIZATION OF CONVECTIVE
LINES...A DAMAGING WIND THREAT APPEARS POSSIBLE WITH THE STRONGEST
STORMS.
