NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 22, 7:43 AM PST, 5 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 843 AM PDT TUE JUL 22 2014 .SYNOPSIS...DRY SOUTHWEST FLOW WITH SEASONABLE TEMPERATURES CAN BE EXPECTED TODAY. THE FLOW WILL BECOME MORE SOUTHERLY BY WEDNESDAY LEADING TO AN INCREASE IN CLOUDS OVER WESTERN ARIZONA AND A SLIGHT CHANCE OF THUNDERSTORMS OVER THE HIGHER TERRAIN THERE. HOT CONDITIONS ARE STILL EXPECTED TO DEVELOP ACROSS THE AREA DURING THE SECOND HALF OF THE WEEK AS HIGH PRESSURE EXPANDS OVER THE DESERT SOUTHWEST. && .UPDATE...HIGH CENTER NEAR EL PASO THIS MORNING WITH MORNING ANALYSIS SHOWING AN INVERTED TROUGH BETWEEN EL PASO AND TUCSON EXTENDING SOUTH INTO NORTHWEST MEXICO. EASTERLY FLOW ACROSS SOUTHERN ARIZONA HAS BROUGHT PRECIP. WATER VALUES BACK ABOVE 1 INCH AT PHOENIX AND TUCSON. MODELS STILL SHOWING SOME OF THIS MOISTURE SPREADING WESTWARD INTO NORTHWEST ARIZONA AND POSSIBLY AS FAR WEST AS EASTERN SAN BERNARDINO COUNTY AND CLARK COUNTIES BEFORE ENCOUNTERING A DRIER SOUTHWESTERLY FLOW. NO UPDATED NEEDED THIS MORNING. FOR THE AFTERNOON PACKAGE, WILL CONTINUE TO LOOK AT THUNDERSTORM CHANCES FOR NORTHWEST ARIZONA IN THE COMING DAYS AS WELL AS HIGH TEMPERATURES AREA WIDE FOR THE REST OF THE WEEK. && .SHORT TERM...THROUGH THURSDAY NIGHT...EXPANDING AREA OF HIGH PRESSURE OVER THE DESERT SOUTHWEST WILL LEAD TO CONTINUED WARMING AND MAINLY DRY CONDITIONS. TEMPERATURES WILL WARM A DEGREE OR TWO EACH DAY THROUGH THE SHORT TERM WITH HIGH TEMPERATURES BY THURSDAY ABOUT FIVE DEGREES ABOVE NORMAL AND JUST A COUPLE OF DEGREES SHY OF EXCESSIVE HEAT WARNING CRITERIA. THE ENTIRE FORECAST AREA LOOKS TO REMAIN PRETTY STABLE TODAY WITH PRECIPITABLE WATER VALUES BEGINNING TO CREEP UP OVER SOUTHERN MOHAVE COUNTY LATE IN THE DAY. A WEAK SHORTWAVE IS PROGGED TO MOVE NORTH INTO WESTERN ARIZONA TONIGHT WHICH WILL BRING SOME ADDITIONAL INCREASE IN MOISTURE INTO MOHAVE COUNTY BY WEDNESDAY. THE MODELS INDICATE SOME WEAK INSTABILITY OVER THE EASTERN HALF OF MOHAVE COUNTY AND JUST ENOUGH MOISTURE FOR A SLIGHT CHANCE OF THUNDERSTORMS OVER SOME OF THE HIGHER TERRAIN. I KEPT A SLIGHT CHANCE MENTIONED FOR THURSDAY AFTERNOON AS THE NAM12 KEEPS SOME MOISTURE AND INSTABILITY IN PLACE. ALL THE MODELS ARE IN AGREEMENT THAT OUTSIDE OF EASTERN MOHAVE COUNTY...THE CWA WILL REMAIN DRY AND STABLE THROUGH THURSDAY NIGHT. .LONG TERM...FRIDAY THROUGH TUESDAY...TWO PRIMARY ITEMS OF INTEREST IN THE EXTENDED PERIOD ARE THE HEAT AND THE RETURN OF SOME MONSOON MOISTURE. BY FRIDAY AFTERNOON...BROAD SUBTROPICAL RIDGE WILL STRETCH FROM SOUTHERN CALIFORNIA ALL THE WAY EAST TO THE SOUTHERN PLAINS, WITH THE RIDGE CENTERED NEAR THE FOUR CORNERS. THIS WILL KEEP THE HEAT FIRMLY ENTRENCHED ACROSS THE SOUTHWEST FRIDAY AND SATURDAY. LATEST ECMWF GUIDANCE HAS TRENDED SLIGHTLY COOLER WITH THE EXTENDED PERIOD TEMPS COMPARED TO LAST NIGHTS RUN WHILE GFS MAINTAINS WARM (BUT COOLER THAN THE ECMWF) TEMPERATURES. THEREFORE I KEPT FRIDAY AS THE HOTTEST DAY AND COOLED TEMPERATURES DOWN VERY SLIGHTLY ON SATURDAY DUE TO THE POSSIBILITY OF SOME ADDED HIGH CLOUD COVER BEGINNING TO WRAP AROUND THE HIGH. ON SUNDAY...MODELS APPEAR TO BE KEYING IN ON THE LIKELIHOOD OF AN INVERTED TROUGH WORKING AROUND THE BASE OF THE HIGH AND PUSHING WEST TOWARDS THE MOJAVE DESERT ON SUNDAY. THIS WOULD RESULT IN A MARKED INCREASE IN CLOUD COVER AND INCREASED COVERAGE OF AFTERNOON AND EVENING CONVECTION. THIS TROUGH WILL CONTINUE TO PUSH EAST ALONG THE SIERRA CREST AND INTO CENTRAL CALIFORNIA EARLY NEXT WEEK WITH THUNDER CHANCES EXPANDING WESTWARD. TRENDED TEMPERATURES CLOSER TO CLIMATOLOGY FROM SUNDAY ONWARD WITH POPS STILL PRIMARILY LIMITED TO MOUNTAIN ZONES. HOWEVER, IF MODEL AGREEMENT CONTINUES TO INCREASE WE MAY NEED TO INCREASE THUNDERSTORM COVERAGE FURTHER DOWN THE ROAD. && .AVIATION...FOR MCCARRAN...SOUTH WINDS NEAR 10 KTS CAN BE EXPECTED THROUGH EARLY THIS MORNING. WINDS WILL GO EASTERLY BY LATE THIS MORNING WITH SPEEDS BETWEEN 5-9 KTS. THE WIND SHOULD SHIFT MORE SOUTHERLY BY LATE AFTERNOON OR EARLY EVENING. SKIES WILL BE MOSTLY CLEAR THROUGH TONIGHT. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...NO SIGNIFICANT WEATHER AFFECTING TERMINALS THROUGH TONIGHT. STRONGEST SURFACE WINDS TODAY WILL OCCUR IN THE OWENS VALLEY WHERE SOUTH WINDS OF 10-20 KTS WITH GUSTS TO 25 KTS ARE POSSIBLE. && .SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME. HOWEVER...SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES. && UPDATE...PIERCE SHORT TERM/AVIATION...HARRISON LONG TERM...OUTLER FOR MORE FORECAST INFORMATION...SEE US ON OUR WEBPAGE: HTTP://WEATHER.GOV/LASVEGAS OR FOLLOW US ON FACEBOOK AND TWITTER
