NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 13, 8:12 AM PST, 3 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 912 AM PDT SUN JUL 13 2014 .SYNOPSIS...STRONG HIGH PRESSURE CENTERED OVER NORTHERN NEVADA WILL BOOST TEMPERATURES SEVERAL DEGREES TODAY. SOME MOISTURE WILL ALSO SPREAD BACK INTO NORTHWEST ARIZONA LEADING TO A CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS. A MOIST SOUTHEAST FLOW WILL INCREASE OVER THE ENTIRE REGION MONDAY AND TUESDAY WITH EXPANDING THUNDERSTORM COVERAGE. && .UPDATE... TEMPERATURES THIS MORNING ARE RUNNING /ON AVERAGE/ 4-6 DEGREES WARMER THAN THIS TIME YESTERDAY. MCCARRAN IS THE WARMEST...RUNNING ABOUT 8 DEGREES WARMER. THE KVEF 12Z SOUNDING INDICATES A 4-5 DEGREE INCREASE THROUGH A LARGE LAYER...GENERALLY SURFACE TO 675 HPA...WHEN COMPARED TO 24 HOURS AGO. FORECAST HIGH TEMP FROM THE SOUNDING SHOWS 110...WHICH IS OUR FORECAST FOR TODAY. WOULD NOT BE SURPRISED IF WE SQUEEZE OUT 111 MAYBE 112...BUT THAT SHOULD BE VERY BRIEF. OTHERWISE...MONSOON MOISTURE CONTINUES TO INCREASE...WITH PWS FOR MUCH OF OUR SOUTHERN AND EASTERN FORECAST AREA INCREASING ROUGHLY 0.25-0.50 INCHES WITHIN THE LAST 24 HOURS. THE MOISTURE IS MAINLY MIDLEVEL WITH LOWER LEVEL MOISTURE ON TAP TO INCREASE OVER THE NEXT 12-30 HOURS FROM EAST TO WEST. THIS IS IN RESPONSE TO AN INVERTED TROUGH CURRENTLY PASSING OVER NORTHERN MEXICO/SOUTHERN AZ...ADVECTING MOISTURE WEST INTO WESTERN AZ...EASTERN CA AND SOUTHERN NV. ALL SIGNS POINT TO MOHAVE COUNTY BEING FAIRLY ACTIVE THIS AFTERNOON AND EVENING. SO HAVE INCREASED POPS ACROSS THAT AREA. WITH THE INVERTED TROUGH TO OUR SOUTH AND HIGH PRESSURE TO OUR NORTH...STORM MOTION WILL BE FROM THE EAST-NORTHEAST. EFFECTIVE AND 0-6 KM BULK SHEAR VALUES WILL INCREASE LATER TODAY GENERALLY INTO THE 20-35 KNOT RANGE...WHERE CONVECTION IS FORECAST TO INITIATE. THESE VALUES WOULD SUPPORT MORE ORGANIZED CONVECTION...SO THIS WILL BE SOMETHING TO WATCH LATER THIS AFTERNOON AND EVENING. && .PREV DISCUSSION... 335 AM PDT SUN JUL 13 2014 .SHORT TERM...THROUGH TUESDAY NIGHT...CIRRUS CLOUD COVER WAS EVIDENT ON IR SATELLITE LOOPS OVER SOUTHERN NEVADA AND SURROUNDING AREAS THIS MORNING. HOWEVER...CLOUD COVER WILL GENERALLY BE THIN THROUGH EARLY AFTERNOON AND A STRONG CLOSED HIGH SETTING UP OVER NORTHERN NEVADA SHOULD PRODUCE THE HOTTEST DAY OF THE WEEK. THIS PATTERN WILL PRODUCE INCREASING EASTERLY FLOW ACROSS THE MOJAVE DESERT REGION AND OPEN THE DOOR FOR MOISTURE FROM ARIZONA TODAY AND TONIGHT. SUFFICIENT MOISTURE AND INSTABILITY SHOULD BE AVAILABLE BY THIS AFTERNOON FOR ISOLATED THUNDERSTORMS OVER NORTHWEST ARIZONA...SOUTHERN SAN BERNARDINO COUNTY AND POSSIBLY LINCOLN COUNTY. IN ADDITION...AN INVERTED TROUGH OVER NORTHWEST MEXICO WILL CONTINUE TO MOVE WEST-NORTHWEST ACROSS NORTHERN BAJA AND BRUSH SOUTHERN CALIFORNIA TONIGHT AND MONDAY. THIS FEATURE ALONG WITH THE MOISTURE ADVECTION MAY AID IN LIGHT SHOWER DEVELOPMENT TONIGHT ACROSS MUCH OF THE REGION AND POPS WERE RAISED TO 15 PERCENT ACROSS MUCH OF NW AZ/SRN NV/SE CA TONIGHT. POPS WILL CONTINUE TO INCREASE MONDAY AND EVEN MORE TUESDAY AS EAST TO SOUTHEAST FLOW WITH PWAT VALUES OF TO 1-1.5 INCHES SPREAD FROM SOUTHEAST TO NORTHWEST ACROSS THE FORECAST AREA. THE INVERTED TROUGH MAY ENHANCE CONVECTION OVER SAN BERNARDINO AND INYO COUNTIES MONDAY. THE REST OF THE REGION SHOULD SEE MORE OROGRAPHIC DRIVEN CONVECTION INITIALLY FOLLOWED BY OUTFLOW BOUNDARY INTERACTION DURING THE AFTERNOON AND EVENING HOURS MONDAY AND TUESDAY. .LONG TERM...WEDNESDAY THROUGH SUNDAY...ABUNDANT MOISTURE WILL REMAIN IN PLACE ACROSS THE REGION ON WEDNESDAY AND THURSDAY BUT WITH THE 500MB ANTICYCLONE LINGERING OVERHEAD...LIMITED FORCING WILL BE AVAILABLE TO INITIATE WIDESPREAD ORGANIZED CONVECTION. THIS SHOULD TIE SHOWER AND THUNDERSTORM CHANCES CLOSELY TO THE HIGHER TERRAIN WITH ANY LOWER ELEVATION ACTIVITY DRIVEN BY OUTFLOW INTERACTIONS. KEPT SLIGHT CHANCES IN THE FORECAST FOR MOST OF THE LOWER ELEVATIONS BUT COVERAGE SHOULD BE NOTICEABLY LESS THAN OBSERVED EARLIER IN THE WEEK. ALSO...WITH A DECREASE IN CLOUD COVER...TEMPERATURES SHOULD BE ABLE TO CREEP A FEW DEGREES ABOVE NORMAL DURING THE AFTERNOONS. ON FRIDAY WE WILL BEGIN TO TRANSITION INTO A DRIER AND MORE STABLE WEATHER PATTERN AS THE RIDGE SHIFTS EAST AND ALLOWS FOR A FAIRLY DEEP SOUTHERLY FLOW TO DEVELOP ACROSS THE AREA. WHILE A SOUTHERLY FLOW THIS TIME OF YEAR CAN BE A VERY MOIST WEATHER PATTERN, GLOBAL MODELS AGREE ON PULLING A POCKET OF VERY DRY AIR NORTHWARD FROM THE EASTERN PACIFIC...ALLOWING US TO DRY OUT A BIT OVER THE WEEKEND. I MAINTAINED AT LEAST SLIGHT CHANCES FOR THUNDER ACROSS MOST OF THE AREA ON FRIDAY BUT DROPPED POPS DOWN QUITE A BIT OVER THE WEEKEND AS DRIER AIR INFILTRATES THE REGION. THE ONLY EXCEPTION WILL BE NORTHWEST INYO COUNTY WHERE A SHORTWAVE LIFTING NORTH MAY ENHANCE PRECIPITATION CHANCES THIS WEEKEND AS IT DRIFTS SLOWLY NORTHWARD. TEMPERATURES WILL REMAIN A FEW DEGREES ABOVE NORMAL THROUGH THE WEEKEND. && .AVIATION...FOR MCCARRAN...DRY CONDITIONS EXPECTED IN THE LAS VEGAS VALLEY TODAY ALTHOUGH ISOLATED THUNDERSTORMS ARE POSSIBLE IN THE PEACH SPRINGS AND MORMON MESA APPROACH CORRIDORS THIS AFTERNOON AND EVENING. EAST TO SOUTHEAST WINDS 6-8 KTS ARE LIKELY AGAIN FROM EARLY AFTERNOON THROUGH EARLY EVENING BEFORE SWITCHING TO THE SOUTH-SOUTHWEST TONIGHT. A SLIGHT CHANCE OF THUNDERSTORMS WILL RETURN TO THE TERMINAL AREA MONDAY AS A MOIST SOUTHEAST FLOW REDEVELOPS. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...ISOLATED THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON MAINLY ACROSS NORTHWEST ARIZONA BUT A FEW THUNDERSTORMS WILL ALSO BE POSSIBLE IN SOUTHEAST NEVADA AND SOUTHEAST CALIFORNIA. LIGHT WINDS AND DRY CONDITIONS CAN BE EXPECTED ACROSS THE REST OF THE REGION. AN INCREASINGLY EAST TO SOUTHEAST FLOW WILL RETURN TONIGHT AND MONDAY THUNDERSTORM COVERAGE EXPANDING ACCORDINGLY. && .SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION IS NOT EXPECTED TODAY. SPOTTER ACTIVATION MAY BE REQUESTED MONDAY OR TUESDAY. SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES. && UPDATE...PADDOCK SHORT TERM/AVIATION...ADAIR LONG TERM...OUTLER FOR MORE FORECAST INFORMATION...SEE US ON OUR WEBPAGE: HTTP://WEATHER.GOV/LASVEGAS OR FOLLOW US ON FACEBOOK AND TWITTER
