MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 405 PM AM PDT MON JUL 28 2003 .SYNOPSIS...THE THREAT OF AFTERNOON AND EVENING THUNDERSTORMS WILL CONTINUE THROUGH AT LEAST MID-WEEK AS A MOIST UNSTABLE AIRMASS CIRCULATES AROUND HIGH PRESSURE CENTERED OVER NORTHERN NEVADA. DISTURBANCES ALOFT WILL FAVOR THUNDERSTORM DEVELOPMENT ACROSS NORTHWEST ARIZONA AND SOUTHEAST CALIFORNIA THIS EVENING AND AGAIN TUESDAY AFTERNOON. .DISCUSSION...CONVECTION WAS FIRING OVER SOUTHERN MOHAVE AND SOUTHEAST SAN BERNARDINO COUNTIES THIS AFTERNOON AS EXPECTED. THE CIRCULATION OBSERVED THIS MORNING OVER ARIZONA APPEARS TO BE A DRIVING FACTOR AND SHOULD CONTINUE TO FAVOR THESE AREAS AS IT MOVES TO THE SOUTHWEST THROUGH THE EVENING. SHEER PROFILES...AVAILABLE MOISTURE AND POTENTIAL INSTABILITY FAVOR ORGANIZED EFFICIENT RAIN PRODUCING STORMS. MOVEMENT IS QUITE FAST BUT REDEVELOPMENT OVER FAVORABLE AREAS COULD BE A PROBLEM. THE 18Z GFS ACTUALLY INDICATES ANOTHER DISTURBANCE COMING OUT OF THE FOUR CORNERS AND INTO SOUTHERN MOHAVE COUNTY BY TUESDAY AFTERNOON SO A SIMILAR AREA COULD BE ACTIVE AGAIN TOMORROW. MOIST SOUTHEAST FLOW ACROSS THE SOUTHERN HALF OF THE AREA REMAINS IN PLACE WEDNESDAY BUT NO APPARENT CONVECTION TRIGGER SO WILL KEEP HIGHER POPS OVER THE MOUNTIANS. DID NOT CHANGE TEMPS MUCH SINCE THEY LOOKED IN THE BALL PARK AND PATTERN CONTINUES TO MAKE PINPOINTING HIGHS AND LOWS DIFFICULT. DAY 3...POSSIBLY AN INTERESTING DAY SETTING UP FOR THURSDAY. THE GFS SHIFTS THE HIGH PRESSURE CENTER ALOFT TO CENTRAL UTAH WITH A CLOSED UPPER LOW LOCATED OFF THE SOUTHWEST COAST. BY 18Z...THE MOISTURE PARAMETERS AND DYNAMICS ARE PROGGED TO BE FAIRLY IMPRESSIVE OVER CLARK COUNTY. THE GFS FORECASTS 65 F DEWPOINTS...11 G/KG MIXING RATIO ...35-40 K-INDEXES AND 1.6 PW FOR LAS VEGAS. THERE IS ALSO IN AN AREA OF LOW-LEVEL CONVERGENCE AND UPPER DIVERGENCE FORECAST AS A 50 KT 250MB JET STREAK MOVES AROUND THE LOW. IN ADDITION...A WEAK VORT MAX IS PROGGED TO MOVE AROUND THE HIGH AND THROUGH SOUTHERN NEVADA. WITH THIS...I DID INCREASE THE POPS SLIGHTLY FOR THE VALLEY AREA FOR THURSDAY BUT THE NEXT FEW MODEL RUNS WILL NEED TO BE ANALYZED FOR THE POSSIBILITY OF HEAVY RAIN AND FLASH FLOODING. EXTENDED...THE UPPER LOW BEGINS TO PULL NORTH AND EAST AS THE UPPER HIGH MIGRATES FURTHER EAST AND THEN SOUTH TO CENTRAL TEXAS BY SUNDAY. THIS WOULD KEEP THE MAIN MOISTURE FLOW WELL EAST OF THE AREA WITH A SOUTHWEST FLOW OVER THE FORECAST AREA. LOWER POPS EXPECTED WITH THE DRIER AIR. WITH LOWER HEIGHTS/THICKNESSES FORECAST...TEMPS EXPECTED TO REMAIN AT OR BELOW NORMAL THROUGH THE EXTENDED. .LAS...NONE ADAIR/SALMEN
