NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 14, 7:43 PM PST, 4 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 843 PM PDT SUN JUL 14 2013 .SYNOPSIS...ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED MAINLY EACH AFTERNOON AND EVENING ACROSS THE HIGHER ELEVATIONS OF EASTERN CLARK AND LINCOLN COUNTIES IN NEVADA AND MOHAVE COUNTY IN NORTHWEST ARIZONA THROUGH THE MIDDLE OF THE WEEK. DRY CONDITIONS ARE EXPECTED ELSEWHERE. A SLOW WARMING TREND WILL CONTINUE INTO MONDAY...WITH TEMPERATURES AT OR SLIGHTLY ABOVE NORMAL THROUGH THE MIDDLE OF THE WEEK. THE POTENTIAL EXISTS FOR AN INCREASE IN THUNDERSTORM ACTIVITY BY THE END OF THE WORK WEEK. && .UPDATE...SHOWERS AND THUNDERSTORMS DEVELOPED ACROSS EASTERN SAN BERNARDINO COUNTY THIS EVENING. A COUPLE OF THESE HAD VERY PERSISTENT DEVELOPMENT AND RESULTED IN FLASH FLOOD WARNINGS THAT ARE ONGOING AS OF 330Z. THE LATEST RADAR TRENDS SHOWED THESE STORMS TAPERING OFF. HAVE UPDATED THE POP/SKY/WX GRIDS TO MATCH THE CURRENT OBSERVATIONS AND TRENDS...WHICH INCLUDED INCREASING CLOUD COVERAGE OVERNIGHT AND MENTIONING A SLIGHT CHANCE OF THUNDERSTORMS ON EASTERN SAN BERNARDINO COUNTY. OTHERWISE THE SHORT TERM FORECAST IS ON TRACK. && .AVIATION...FOR MCCARRAN...AN OUTFLOW BOUNDARY PASSED THROUGH THE AREA JUST BEFORE 02Z THIS EVENING SHIFTING THE WINDS TO THE SOUTH EAST. THESE SOUTHEAST WINDS SHOULD GIVE WAY TO USUAL SOUTHWESTERLY DRAINAGE WINDS UNDER 12 KTS BY 05-06Z. SHOWERS/THUNDERSTORMS AGAIN ON MONDAY WILL BE EAST OF LAS VEGAS AND MAY IMPACT THE PEACH SPRINGS CORRIDOR. WIND ON MONDAY AGAIN SHOULD FAVOR A EAST TO SOUTHEAST DIRECTION UNDER 10KTS. SCT-BKN CLOUDS ABV 15 KFT THROUGH THE PERIOD. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...AN OUTFLOW BOUNDARY CONTINUES TO PUSH WEST ACROSS THE AREA...WITH WINDS FAVORING AN EASTERLY DIRECTION BEHIND IT. THE LATEST TRENDS SHOWED THIS BOUNDARY WAS LOOSING STEAM WEST OF LAS VEGAS. THESE EAST WINDS SHOULD GIVE WAY TO USUAL DIURNAL WINDS UNDER 12 KTS BY 05-06Z IN MOST LOCATIONS. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS OVER SOUTHERN MOHAVE AND SAN BERNARDINO COUNTIES SHOULD TAPER OFF BETWEEN 03-04Z. STORMS WILL DEVELOP AGAIN AFT 17Z MONDAY. ONLY SCT GENERALLY ABOVE 15 KFT ACROSS INYO...NYE...ESMERALDA AND WRN SAN BERNARDINO COUNTIES. SOUTHERLY WIND DIRECTION GENERALLY UNDER 12 KTS INTO THE EVENING...WHILE GUSTS TO 15-20 KTS WILL OCCUR IN THE OWENS VALLEY. SIMILAR SOUTH WINDS DEVELOPING MONDAY AFTERNOON. && .PREV DISCUSSION... ISSUED 305 PM PDT SUN JUL 14 2013 .SHORT TERM...THROUGH WEDNESDAY NIGHT...CONVECTIVE WISE...THIS AFTERNOON LOOKING VERY SIMILAR TO YESTERDAY. ISOLATED SHOWERS/THUNDERSTORMS OVER ERN LINCOLN AND CLARK COUNTIES...WITH STORMS BECOMING SCATTERED OVER MOHAVE COUNTY. OVER SIX TENTHS OF AN INCH OF RAIN FELL ON THE DEAN PEAK BURN SCAR SOUTHEAST OF KINGMAN IN THE LATE MORNING PRODUCING FLASH FLOOD/DEBRIS FLOW WHICH IMPACTED ROADWAYS BETWEEN PINION PINES AND INTERSTATE 40. MONSOON MOISTURE BOUNDARY PROGGED TO REMAIN ALIGNED OVER SIMILAR GEOGRAPHICAL AREA TOMORROW. SO DID BRING THE MENTION FOR A SLIGHT CHANCE OF SHOWERS/THUNDERSTORMS BACK FURTHER WEST INTO SRN AND ERN CLARK COUNTY. ISOLATED TO SCATTERED STORMS EXPECTED IN ERN LINCOLN AND MOHAVE COUNTIES. ON TUESDAY AND WEDNESDAY...LOOKING FOR BEST INSTABILITY AND DEEPER MOISTURE TO BE SHUNTED SLIGHTLY FURTHER EAST WITH THUNDERSTORMS CHANCES BEST IN ERN LINCOLN AND MOHAVE COUNTIES. RAINFALL INTENSITY FROM STORMS SHOULD DIMINISH OVER THE COMING DAY...BUT WE WILL CONTINUE TO MONITOR RAINFALL RATES NEAR RECENT BURN SCARS AND ISSUE PRODUCTS WHEN NECESSARY. THE WESTERN HALF OF OUR AREA WILL REMAIN DRY. TEMPERATURES WILL BE AT OR SLIGHTLY ABOVE NORMAL. .LONG TERM...TUESDAY THROUGH SATURDAY...HIGH PRESSURE STILL EXPECTED TO BE OVER UTAH TUESDAY AND WEDNESDAY WITH A SOUTHERLY FLOW OVER THE FORECAST AREA. NORTH-SOUTH MOISTURE BOUNDARY STILL PROGGED TO BE EAST OF LAS VEGAS AND I KEPT A CHANCE OF THUNDERSTORMS IN THE FORECAST FOR MUCH OF MOHAVE COUNTY AND EASTERN LINCOLN COUNTY. MOISTURE AND THUNDERSTORM CHANCES MAY AT LEAST GRADUALLY SPREAD WEST THURSDAY THROUGH SATURDAY AS THE WEST/SOUTHWEST MOVING UPPER LOW MOVES INTO NORTHWEST MEXICO AND AN EASTERLY COMPONENT DEVELOPS TO THE FLOW. THE MODELS ALL DIFFER IN THE EXACT POSITION OF THAT LOW AND HOW FAR WEST AND NORTH THE MOISTURE SPREADS. THE GFS SOLUTION IS NOT AS FAVORABLE FOR THE MOISTURE INCREASE AS IT KEEPS THE FLOW MORE NORTHERLY THAN THE ECMWF AND GEM. THEREFORE...DUE TO THESE MODEL DIFFERENCES AND RELATIVELY LOW CONFIDENCE...ONLY VERY MINOR CHANGES WERE MADE TO THE POP GRIDS FOR THURSDAY THROUGH SATURDAY. THUNDERSTORM CHANCES WERE MENTIONED ACROSS ALL OF CLARK...LINCOLN AND MOHAVE COUNTIES AND EASTERN SAN BERNARDINO COUNTY BY SATURDAY. ECE AND MEX GUIDANCE MAX TEMPS DIFFERED BY SEVERAL DEGREES MOST DAYS AND THE FORECAST IS BASICALLY A BLEND OF THE TWO WHICH BASICALLY PUTS THEM CLOSE TO NORMAL...MAYBE SLIGHTLY BELOW NORMAL BY SATURDAY. && .LONG TERM...THURSDAY THROUGH SUNDAY...THE MAIN FEATURE TO WATCH DURING THIS PERIOD IS THE UPPER LEVEL LOW THAT IS CURRENTLY MOVING TO THE SOUTHWEST ACROSS THE COUNTRY. THIS FEATURE WILL BRING INCREASED MOISTURE ACROSS MUCH OF THE FORECAST AREA. THE OPERATIONAL MODELS EACH HAVE SLIGHT DIFFERENCES IN THE EXACT PLACEMENT AND TIMING OF THIS FEATURE...THIS WILL AFFECT THE TIMING AND EXTENT OF ANY MOISTURE INCREASE IN OUR REGION. THE ECMWF SEEMS TO BE THE MOST AGGRESSIVE WITH BRINGING IN MOIST UNSTABLE AIR INTO THE REGION FOR THE UPCOMING WEEKEND. AFTER COORDINATING WITH NEIGHBORING OFFICES I HAD ENOUGH CONFIDENCE TO INCREASE POPS AND SKY COVER ACROSS THE REGION FOR FRIDAY THROUGH THE END OF THE EXTENDED FORECAST PERIOD. I ALSO INCREASED THE AREA WHERE THUNDERSTORM CHANCES ARE MENTIONED FROM FRIDAY ONWARD. GUIDANCE STILL SHOWS A WIDE RANGE OF DIFFERENT MAXIMUM TEMPERATURE VALUES FOR THE EXTENDED PERIOD...AS A RESULT I ONLY MADE MINOR CHANGES TO THE INHERITED GRIDS BY USING A BLEND OF THE MEX AND THE ECMWF. ULTIMATELY HIGH TEMPERATURE FRIDAY THROUGH THE END OF THE EXTENDED WILL DEPEND ON HOW MUCH CLOUD COVER FORMS AND THE TIMING AND PLACEMENT OF THUNDERSTORMS EACH DAY. && .FIRE WEATHER...ISOLATED AND MAINLY WET SHOWERS/THUNDERSTORMS ARE EXPECTED INTO WEDNESDAY MOSTLY OVER THE HIGHER ELEVATIONS OF MOHAVE AND ERN LINCOLN COUNTIES. STRONGER SOUTH WINDS AND LOW RELATIVE HUMIDITY VALUES ARE EXPECTED ON TUESDAY ACROSS ESMERALDA AND NYE COUNTIES. NOT CONFIDENT ENOUGH AT THIS TIME TO ISSUE A FIRE WEATHER WATCH...SOMETHING FOLLOWING SHIFTS WILL NEED TO KEEP AN EYE ON THOUGH. MODELS POINT TO A POTENTIAL INCREASE IN SHOWER/THUNDERSTORM ACTIVITY BY LATE THIS WEEK. && .VEF WATCHES/WARNINGS/ADVISORIES... NV...NONE. AZ...NONE.
