AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 307 PM PDT SUN JUL 27 2008 .SYNOPSIS...SCATTERED THUNDERSTORMS WILL AFFECT PORTIONS OF SOUTHERN NEVADA AND NORTHWEST ARIZONA THROUGH THIS EVENING. DRIER AIR WILL SPREAD INTO THE AREA MONDAY AND TUESDAY BRINGING ON A WARMING TREND FOR MOST OF THE UPCOMING WEEK. && .SHORT TERM...MID-LEVEL CIRCULATION CENTER WAS OVER THE OWENS VALLEY AT 2030Z ENHANCING CONVECTIVE DEVELOPMENT FROM THE SIERRA CREST EAST ACROSS CENTRAL NEVADA. THIS FEATURE IS FORECAST TO MOVE INTO UTAH OVERNIGHT WITH DRY SOUTHWEST FLOW DEVELOPING IN ITS WAKE. DEWPOINTS HAVE LOWERED ALREADY TODAY BUT PW IS STILL GREATER THAN 1 INCH OVER MOST OF THE CWA. ISOLATED THUNDERSTORMS ARE STILL POSSIBLE TOMORROW FROM LINCOLN COUNTY NEVADA SOUTH TO MOHAVE COUNTY ARIZONA AS LOW LEVEL MOISTURE WILL PROBABLY BE SLOW TO COMPLETELY SCOUR OUT. AFTER THAT...THE FORECAST IS FOR WARMING AND DRYING THROUGH AT LEAST THURSDAY AS LARGE UPPER RIDGE BUILDS IN OVER ARIZONA. -RUNK- .LONG TERM...AN UPPER LEVEL RIDGE CENTERED OVER ARIZONA IS PROGGED TO STRENGTHEN ACROSS THE SOUTHWESTERN CONUS WEDNESDAY INTO THE LATER PART OF THIS WEEK. AS THE PREVIOUS SHIFT NOTED...THERE CONTINUES TO BE SOME SUBTLE DIFFERENCE BETWEEN BOTH THE OPERATIONAL LONG RANGE GLOBAL MODELS AND THE GFS ENSEMBLES AS TO WHERE THIS HIGH BECOMES EXACTLY CENTERED...BUT FOR THE PERIOD FROM WEDNESDAY THROUGH FRIDAY...THE MODEL CONSENSUS DOES NOT FAVOR ANY INFLUX OF MOISTURE INTO THE CWFA AS THE FLOW ALOFT LOOKS TO REMAIN SOUTHWESTERLY WHICH SHOULD KEEP THINGS DRIED OUT. GIVEN THIS...WE HAVE MADE FURTHER ADJUSTMENTS UPWARDS WITH MAX TEMPS FOR THIS TIME FRAME AND ARE FORECASTING TEMPS ABOUT 4 TO 6 DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR. THIS IS WELL SUPPORTED BY 500MB HEIGHTS PROGGED TO REACH AT OR ABOVE 591DM AND 700MB TEMPERATURES PROGGED TO REACH BETWEEN +15C AND +17C ACROSS MUCH OF THE AREA DURING THIS TIME FRAME. FOR SATURDAY AND BEYOND...THE HIGH MAY BECOME CENTERED IN A FAVORABLE ENOUGH POSITION TO ALLOW FOR MONSOONAL MOISTURE TO SLOWLY RETURN TO THE CWFA. ONCE AGAIN...THE ECMWF IS THE MOST AGGRESSIVE WITH SUCH A PATTERN CHANGE. WE HAVE IN SOME SLIGHT CHANCE POPS IN THE SOUTHEAST PORTION OF THE CWFA STARTING SATURDAY WITH A SUBTLE TREND UPWARDS INTO SUNDAY. WITH THE ATMOSPHERE POTENTIALLY BEING MORE MOIST AND MORE CLOUD COVER/CONVECTION EXPECTED...TEMPS SHOULD SLOWLY TREND DOWN SOME. && .AVIATION...FOR MCCARRAN...STILL THINK ANY TSTMS WILL STAY OUT OF THE LAS VEGAS VALLEY THIS EVENING...BUT GIVEN THAT WE HAVE HAD SOME ACTIVITY OVER THE SPRING AND SHEEP RANGES...DO PLAN TO KEEP IN A CB IN THE SKY COVER. HOWEVER...ISOLATED SHRA AND TSTMS WILL BE AROUND THIS EVENING IN THE APPROACH CORRIDORS...ESPECIALLY NORTH AND EAST OF LAS VEGAS. GENERALLY SCT CLOUDS TONIGHT AT/ABOVE 15K FEET...THEN AS DRIER AIR WORKS INTO THE AREA TOMORROW SHOULD JUST SEE CLOUDS GO MORE INTO THE FEW RANGE. SOUTHERLY WIND GUSTS OF 15-20KTS THIS EVENING AND LIKELY AGAIN TOMORROW AFTERNOON/EVENING AS WELL. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...AN UPPER LEVEL FEATURE WILL ALLOW FOR ISOLATED SHRA AND TSTMS TO CONTINUE THIS EVENING ACROSS PARTS OF LINCOLN...NYE AND INYO COUNTIES. KEPT IN A CB FOR KBIH FOR THIS EVENING...BUT THINK ANY TSTMS SHOULD STAY OVER THE SIERRA AND WHITE MTNS AND IF ANY ACTIVITY FROM THE SIERRA MOVES TOWARDS THE OWENS VALLEY DRIER LOW LEVELS SHOULD SIGNIFICANTLY LIMIT ODDS FOR ANY RAIN TO FALL THERE. ADDITIONAL TSTMS WILL BE AROUND THIS EVENING ACROSS THE SOUTHEAST CORNER OF THE AREA...MAINLY IN MOHAVE COUNTY. MAIN THREAT IN STORMS WILL BE LOCALLY HEAVY DOWNPOURS DROPPING VSBY AND CIGS IN LOCAL AREAS TO MVFR OR IFR LEVELS AND GUSTY WINDS. FEW-SCT CLOUDS AT/ABOVE 15K FEET TONIGHT WITH GENERALLY LIGHT WINDS ACROSS THE AREA. DRIER AIR WORKING INTO THE AREA TOMORROW SHOULD LIMIT ANY CHANCES FOR AN ISOLATED TSTM TO JUST THE HIGHER TERRAIN OF MOHAVE COUNTY. ELSEWHERE FEW-SCT CLOUDS AT/ABOVE 15K FEET. TYPICAL SOUTHERLY GUSTY AFTERNOON WINDS OF 15-20 KTS ARE EXPECTED IN THE OWENS VALLEY AND AROUND KDRA. && RUNK/STACHELSKI .VEF WATCHES/WARNINGS/ADVISORIES... NV...NONE. AZ...NONE.
