AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 950 AM PDT MON JUL 13 2009 .SYNOPSIS...HOT WEATHER IS EXPECTED THIS WEEK AS HIGH PRESSURE BUILDS INTO THE DESERT SOUTHWEST. LATE IN THE WEEK...THERE COULD BE A PUSH OF MOISTURE FROM THE SOUTHEAST...WHICH WOULD BRING A CHANCE OF THUNDERSTORMS. && .UPDATE...TWO THIN STREAMS OF MOISTURE EVIDENT ON WATER VAPOR THIS MORNING. ONE CURRENTLY PUSHING UP FROM THE SOUTHWEST ACROSS THE SOUTHERN HALF OF THE CWA IS REMNANTS OF CARLOS. THIS IS EXPECTED TO ONLY BRING A FEW CIRRUS CLOUDS FOR THE REMAINDER OF TODAY. A SECOND STREAM FROM PREVIOUS TROPICAL STORM BLANCA IS PUSHING INTO NORTHERN INYO COUNTY. THIS HAS A LITTLE MORE LOW LEVEL MOISTURE ASSOCIATED WITH IT...BUT A FEW CUMULUS CLOUDS SHOULD BE IT FOR THE SIERRA. BIG STORY OVER THE NEXT FEW DAYS WILL BE THE STRONG HIGH PRESSURE BUILDING IN FROM THE EAST. WE ARE STILL LOOKING FOR THE POSSIBILITY OF HEAT WARNING CRITERIA /112 DEGREES/ BY THE END OF THE WEEK. NO UPDATES PLANNED. && .AVIATION...FOR MCCARRAN...ASIDE FROM BRIEF PERIODS OF CIRRUS MOVING THROUGH EXPECT MOSTLY CLEAR SKIES THROUGH TUESDAY. WINDS WILL BE SOUTH AROUND 10-18KTS THROUGH 02Z THIS EVENING AND BECOME LIGHT OVERNIGHT. TEMPERATURES WILL REMAIN QUITE WARM AND BRING THE USUAL THERMAL TURBULENCE IN THE AFTERNOON. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...GENERALLY CLEAR SKIES ACROSS THE AREA. SOUTHWEST WINDS 10-20KTS WITH GUSTS NEAR 25KTS THROUGH THIS AFTERNOON. GENERALLY LIGHT WINDS OVERNIGHT. && .PREV DISCUSSION...316 AM PDT MON...SHORT TERM...WATER VAPOR SHOWS THREE FEATURES OF NOTE THIS MORNING. THE LOW PRESSURE AREA OVER OREGON WILL MOVE AWAY INTO THE NORTHERN ROCKIES TODAY...THE REMNANTS OF TROPICAL STORM BLANCA WERE FEEDING HIGH LEVEL MOISTURE INTO OUR AREA...AND THE BIG RIDGE OVER THE SOUTHERN PLAINS WILL BRING HEAT CONCERNS THIS WEEK. AT 2 AM...SATELLITE SHOWED CLEAR SKIES OVER THE SOUTHERN GREAT BASIN AND CIRRUS OVER THE MOJAVE DESERT COURTESY OF BLANCA. THE REMNANTS OF TROPICAL SYSTEMS ALWAYS DESERVE EXTRA SCRUTINY...AS WAS PROVEN IN AUGUST 2007 WHEN THE REMNANT CIRCULATION OF FORMER ATLANTIC HURRICANE DEAN PRODUCED MAJOR FLOODING IN LAS VEGAS. HOWEVER...THE LEFTOVERS OF BLANCA HAVE BEEN SITTING OVER COLD WATERS FOR QUITE SOME TIME...AND WATER VAPOR SUGGESTS A TREMENDOUS AMOUNT OF DRY AIR SURROUNDING THE SYSTEM...SO WILL HESITANTLY ACCEPT THE MODEL OUTPUT WHICH CALLS FOR BLANCA TO BE A NON-FACTOR IN OUR SENSIBLE WEATHER. AS THE OREGON LOW MOVES AWAY...GRADIENTS WILL CONTINUE TO RELAX OVER THE NORTHERN ZONES...AND WINDS WILL NOT BE STRONG ENOUGH TODAY TO JUSTIFY ANOTHER RED FLAG WARNING. THIS LEAVES HEAT AS OUR MAIN CONCERN. THE HIGH OF 109F AT KLAS SUNDAY WAS THE HIGHEST SO FAR THIS YEAR...AND THERE IS MORE TO COME AS THE RIDGE SLOWLY WORKS ITS WAY WEST. THERE COULD BE A SLIGHT REPRIEVE TODAY AND TUESDAY AS THE OREGON LOW AND THE REMNANTS OF BLANCA SUPPRESS HEIGHTS JUST A BIT...BUT THE RIDGE WILL ASSERT ITSELF BEGINNING WEDNESDAY AND WE COULD START FLIRTING WITH EXCESSIVE HEAT WARNING CRITERIA /112F AT KLAS/. .LONG TERM...RIDGING STILL THE DOMINANT FEATURE FOR THE EXTENDED FORECAST PERIOD. MODELS STILL DIFFER ON EXACT POSITIONING OF THE CENTER OF IT WITH IT BEING SOMEWHERE IN THE VICINITY OF THE FOUR CORNERS TO EASTERN NEVADA. THIS COULD MAKE A DIFFERENCE IN THE TEMPERATURE FORECAST AND MOISTURE ADVECTION. FOR NOW IT LOOKS LIKE THE ONGOING FORECAST IS A COMPROMISE ON THESE PARAMETERS. FORECAST HIGHS OF 111 ON THURSDAY AND FRIDAY IS CLOSE TO HEAT WARNING CRITERIA WHICH MAY BE REQUIRED IF THE ECMWF FORECAST OF 500MB HEIGHTS OF 597/8 OCCUR. STILL KEPT IN THE 20 PERCENT CHANCE OF THUNDERSTORMS FOR MOHAVE COUNTY NEXT WEEKEND AS ALL MODELS HAVE THE RIDGE BACKED OFF TO THE EAST TO ALLOW SOME MOISTURE INTO THE AREA THEN. TEMPERATURES WILL ALSO MODERATE A BIT AS WELL IN RESPONSE TO THE MOISTURE INCREASE. && .VEF WATCHES/WARNINGS/ADVISORIES... NV...NONE. AZ...NONE.
