The episode as NWS VEF wrote it up.
Lingering monsoon moisture continued to fuel thunderstorms over the Mojave Desert. A few storms produced flash flooding.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Sep 9, 2:23 PM PST, 2 hours 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 323 PM PDT MON SEP 9 2013 .SYNOPSIS...A SLOW MOVING AREA OF LOW PRESSURE COMBINED WITH RESIDUAL MOISTURE WILL HELP TO TRIGGER SHOWERS AND THUNDERSTORMS ACROSS THE AREA ESPECIALLY IN LINCOLN...CLARK...MOHAVE AND EASTERN SAN BERNARDINO COUNTIES. THE PRIMARY HAZARD WITH STORMS WILL BE HEAVY RAIN BRINGING THE POTENTIAL FOR FLASH FLOODING. DRIER AIR WILL START TO SPREAD EAST ACROSS THE AREA WEDNESDAY NIGHT INTO FRIDAY BRINGING AN END TO ANY SHOWER AND THUNDERSTORM ACTIVITY. TEMPERATURES ARE EXPECTED TO THEN RISE TO ABOVE NORMAL THIS WEEKEND. && .SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT. MONSOON MADNESS CONTINUES THIS AFTERNOON BUT A BREAK AWAITS LATER THIS WEEK FOR EVERYONE. A MID/UPPER LEVEL LOW PRESENTLY LOCATED OVER SOUTHWESTERN MOHAVE COUNTY NEAR YUCCA CONTINUES TO BE THE CULPRIT DRIVING CONVECTION THIS AFTERNOON IN CAHOOTS WITH LINGERING MOISTURE AND INSTABILITY ACROSS THE EASTERN HALF OF OUR AREA. AS WAS THE CASE YESTERDAY EVENING, THE NORTHWEST FLANK OF THE LOW HAS BEEN SEEING THE MOST CONVECTION BLOSSOM AND THIS MAKES SENSE AS THE BEST MID-LEVEL CONVERGENCE IS SHOWN IN THE STREAMLINES OVER THIS AREA. STORM MOVEMENT TODAY HAS BEEN THE ONE FACTOR THAT MAKES IT TOUGH TO PINPOINT WHERE FLASH FLOODING WILL BE A BIGGER CONCERN AND AS A RESULT WE HAVE HELD OFF ON ANY FLASH FLOOD WATCHES FOR THIS EVENING AND WE WILL ADDRESS ANY FLASH FLOOD CONCERNS WITH THE APPROPRIATE SHORT-FUSED PRODUCTS. WHILE MOHAVE AND EASTERN SAN BERNARDINO COUNTIES AND TO A LESSER EXTENT SOUTHERN LINCOLN COUNTIES ARE THE MOST ACTIVE NOW, THERE IS THE POTENTIAL GIVEN THE NORTHEAST STEERING FLOW IN PLACE OVER CLARK COUNTY THAT ACTIVITY THAT DEVELOPS OVER SOUTHERN LINCOLN COUNTY, SOUTHWEST UTAH AND NORTHWEST ARIZONA COULD MIGRATE DOWN TO CLARK COUNTY THIS EVENING IN THE FORM OF EITHER SHOWERS AND THUNDERSTORMS OR AN OUTFLOW BOUNDARY. THE LATEST HRRR, NMM AND WRF MODELS ALL SUPPORT THIS. THIS TYPE OF STORM MOVEMENT INTO LAS VEGAS IN THE PAST (A.K.A THE JULY 18TH 1994 HILTON SIGN THUNDERSTORM AND MORE RECENTLY JULY 19TH OF THIS YEAR) HAS SUPPORTED TYPICALLY MID TO LATE EVENING THUNDERSTORMS THAT CAN PACK A PUNCH AS THEY PICK UP MOMENTUM DROPPING OFF THE HIGHER TERRAIN TO THE NORTHEAST. WE SHALL SEE WHAT HAPPENS AS THIS EVENING PROGRESSES BUT FOR NOW I HAVE INCREASED POPS THIS EVENING FROM LAS VEGAS UP TOWARD MESQUITE TO ACCOUNT FOR THE MODEL TRENDS. THE MID/UPPER LEVEL LOW IS FORECAST TO MOVE VERY SLOWLY TO THE EAST AND EVENTUALLY NORTHEAST TONIGHT INTO TUESDAY TRAVELING TOWARD NORTHERN MOHAVE COUNTY. AS A RESULT, SHOWERS AND THUNDERSTORMS WILL CONTINUE IN THE FORECAST MAINLY NEAR THE LOW. SOME AREAS MAY SEE A BREAK TONIGHT IF THEY GET WORKED OVER THIS EVENING, THOUGH A LOT OF MOISTURE IS SHOWN TO LINGER SO CLOUD COVER MAY NOT DEVELOP TOO MANY BREAKS. FOR TUESDAY, THE BEST CONVERGENCE IS SHOWN TO BE OVER CLARK COUNTY WHICH WOULD ALSO CREATE AN UPSLOPE FLOW OVER THE SPRING MOUNTAINS. THIS IS ALSO THE AREA IN THE NORTHWEST QUADRANT OF THE LOW, WHICH HAS BEEN THE HOT SPOT FOR CONVECTION THE PAST TWO DAYS. I DID NOT ISSUE ANY FLASH FLOOD WATCHES FOR NOW, BUT GIVEN THE CARPENTER 1 FIRE BURN AREA BEING SO SENSITIVE, IT MAY BE A CONSIDERATION WITH THE NEXT PACKAGE OR SO. OTHERWISE MOHAVE AND LINCOLN COUNTIES SHOULD SEE THE BEST CHANCES FOR SHOWERS AND THUNDERSTORMS AND HERE AS WELL THE RISK FOR FLASH FLOODING WILL EXIST WITH SOME STORMS. BASED ON THE LATEST WRF, SREF AND GFS I ALSO INCREASED POPS A LITTLE BIT FURTHER WEST OVER CENTRAL NYE COUNTY. TEMPS ARE A TOUGH CALL BUT LOOK TO STAY BELOW NORMAL ESPECIALLY OVER EASTERN SECTIONS. FROM TUESDAY NIGHT INTO WEDNESDAY, THE LOW IS FORECAST TO DRIFT NORTH OR EVEN NORTHWEST TOWARD SOUTHEASTERN NEVADA AND SOUTHWEST UTAH. THIS WILL FOCUS THE BEST CHANCE OF SHOWERS AND THUNDERSTORMS OVER LINCOLN, CLARK AND MOHAVE COUNTIES, HOWEVER A LOT OF MID-LEVEL MOISTURE IS SHOWN TO WRAP AROUND THE BACK SIDE OF THE LOW SO WE HAVE CARRIED A CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS THE ENTIRE AREA. FLASH FLOODING WILL AGAIN BE THE MAIN THREAT. TEMPS AGAIN SHOULD REMAIN BELOW NORMAL ESPECIALLY IN THE EAST. THE LOW IS FORECAST TO DRIFT NORTH TOWARD ELY WEDNESDAY NIGHT INTO THURSDAY NIGHT. THIS WILL STILL ALLOW FOR SHOWERS AND THUNDERSTORMS TO LINGER ESPECIALLY ACROSS LINCOLN COUNTY AND TO A LESSER EXTENT CLARK, MOHAVE AND CENTRAL NYE COUNTIES. I DID INCREASE POPS IN THESE AREAS GIVEN THE BETTER MODEL CONSENSUS WITH THE PLACEMENT OF THE LOW. DRIER AND MORE STABLE AIR IS SHOWN TO PUSH IN FROM THE SOUTHWEST WHICH SHOULD HELP TO TRIM BACK ON THE PROSPECTS FOR CONVECTION OVER THE SOUTHWEST CWFA SIGNIFICANTLY. .LONG TERM...A MID/UPPER LEVEL RIDGE IS FORECAST TO BUILD INTO CALIFORNIA FROM THE EASTERN PACIFIC THURSDAY NIGHT INTO FRIDAY AND FINALLY PUSH THE PESKY LOW OFF TO THE EAST. THIS RIDGE WILL BRING DRIER AND MORE STABLE AIR WITH TO ALL AREAS AND ALSO ALLOW FOR A WARMING TREND AS WELL AS A RETURN TO SUNNIER CONDITIONS. BASED ON GFS BUFR FORECAST SOUNDINGS AS WELL AS THE LATEST STATISTICAL GUIDANCE I WENT AHEAD AND INCREASED HIGH TEMPS FROM FRIDAY THROUGH NEXT WEEKEND. TRIPLE DIGITS ARE NOT OUT OF THE QUESTION AGAIN IN VEGAS. THIS WOULD BE THE FIRST DRY WEEKEND IN A MONTH OR MORE EXACTLY SINCE AUGUST 10TH AND 11TH FOR LAS VEGAS. && .AVIATION...FOR MCCARRAN...THE MAIN CONCERN FOR THIS EVENING WILL BE IF ANY SHRA/TSRA APPROACH THE AIRPORT. THE STEERING FLOW FROM STORMS IS FROM THE NORTHEAST AND THERE IS DECENT POTENTIAL FOR ACTIVITY TO DRIFT INTO THE AIRPORT FROM THAT DIRECTION ESPECIALLY FROM 03Z THROUGH 08Z TUESDAY WHICH WOULD BRING GUSTY AND ERRATIC WINDS AS WELL AS REDUCED CIGS/VSBY IMPACTING CONFIGURATIONS. DEPENDING ON WHAT HAPPENS IN THAT TIME FRAME, WINDS MAY BE ERRATIC AT TIMES, OTHERWISE THEY SHOULD FAVOR TYPICAL DIURNAL DIRECTIONS THROUGH TUESDAY MORNING. SHRA/TSRA ARE POSSIBLE AGAIN ON TUESDAY AT ANYTIME...ESPECIALLY AFTER 18Z. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...SHRA/TSRA WILL CONTINUE ACROSS THE AREA ESPECIALLY THROUGH 08Z TUESDAY. ACTIVITY SHOULD BE GREATEST IN MOHAVE, LINCOLN, CLARK AND EASTERN SAN BERNARDINO COUNTIES. ON TUESDAY, SHRA/TSRA ARE EXPECTED ESPECIALLY AFTER 18Z ACROSS MOHAVE, LINCOLN AND CLARK COUNTIES. GUSTY AND ERRATIC WINDS AS WELL AS REDUCED CIGS AND VSBY WILL ALL BE ISSUES IN AND NEAR ANY SHRA/TSRA. && .VEF WATCHES/WARNINGS/ADVISORIES... NV...NONE. AZ...NONE.
