MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 346 PM PDT WED JUL 16 2003 .SYNOPSIS...SOUTHEAST FLOW AROUND AN UPPER HIGH OVER COLORADO WILL KEEP A FAIRLY MOIST AND UNSTABLE AIRMASS OVER THE AREA INTO THE WEEKEND. THIS WILL CAUSE A CHANCE OF THUNDERSTORMS OVER MUCH OF THE AREA...ESPECIALLY BY FRIDAY. HIGH TEMPERATURES WILL BE CLOSER TO NORMAL LEVELS DURING THE REMAINDER OF THE WEEK. .DISCUSSION...A DECENT AMOUNT OF THUNDERSTORM ACTIVITY DEVELOPED OVER MOHAVE COUNTY THIS AFTERNOON WITH SOME GUSTY WINDS THE MAIN THREAT. SOME OF THIS ACTIVITY WILL DRIFT INTO SOUTHERN NEVADA WHILE THUNDERSTORMS IN SAN BERNARDINO COUNTY WILL DRIFT INTO INYO COUNTY. WILL HAVE TO MENTION EVENING THUNDERSTORMS OVER MUCH OF THE FORECAST AREA. POSSIBILITY OF THUNDERSTORMS CONTINUES IN MOHAVE COUNTY OVERNIGHT AS MOISTURE AND A SHORTWAVE TROUGH MOVE IN FROM THE EAST. MODELS DO NOT SEEM TO BE DOING THAT WELL IN THE SHORT TERM. LOTS OF MIXED SIGNALS BETWEEN THE GFS AND ETA WITH RESPECT TO MOISTURE AND INSTABILITY. SEEMS LIKE MOISTURE AND INSTABILITY SHOULD BE INCREASING WITH THE PERSISTENCE OF SOUTHEAST FLOW AROUND THE HIGH OVER COLORADO AND THE APPROACH OF THE REMAINS OF CLAUDETTE. MODELS SEEM TO BE UNDERDONE WITH MAINLY THE INSTABILITY. WILL CONTINUE TO FORECAST A SLIGHT CHANCE OF THUNDERSTORMS OVER THE FORECAST AREA THURSDAY AT LEAST OVER THE HIGHER TERRAIN AND THEN INCREASE POPS AND COVERAGE FRIDAY. THERE COULD BE A DECREASE IN MOISTURE BY SATURDAY AS THE REMAINS OF CLAUDETTE MOVES INTO THE PACIFIC AND THE UPPER HIGH PUSHES A BIT TO THE WEST. DO NOT BELIEVE THE MOISTURE WILL BE FLUSHED OUT HOWEVER AND WILL LEAVE A SLIGHT CHANCE OF THUNDERSTORMS OVER THE FORECAST AREA. NO MAJOR CHANGES IN TEMPERATURES EXPECTED THROUGH SATURDAY BUT THURSDAY AND FRIDAY WILL LIKELY BE SLIGHTLY COOLER DUE TO INCREASED MOISTURE. WINDS WILL REMAIN FAIRLY LIGHT WITH THE EXCEPTION OF THUNDERSTORM WINDS. EXTENDED MODELS REMAIN IN GOOD AGREEMENT KEEPING A SOMEWHAT MOIST SOUTHERLY FLOW THROUGH DAYS 4 AND 5. MODELS DO SHOW THE UPPER HIGH TO SHIFT SLOWLY WEST AND CENTER MORE OVER ARIZONA. THIS WILL LIKELY KEEP MUCH OF THE MOISTURE SOUTH AND WEST OF THE AREA...BUT STILL LOOKING FOR SOME MOISTURE TO WORK INTO THE CWA. HAVE KEPT THE MENTION OF SHOWERS AND THUNDERSTORMS IN THE FORECAST BUT ONLY A SLIGHT CHANCE AND MOST SHOULD BE CONFINED TO THE HIGHER TERRAIN. HARRISON/GORELOW .LAS...NONE.
