The episode as NWS VEF wrote it up.
A boy died in Las Vegas after being left in a vehicle.
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 Aug 27, 8:58 AM PST, 3 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 958 AM PDT THU AUG 27 2015 .SYNOPSIS...THUNDERSTORM CHANCES ARE EXPECTED TO DECREASE OVER THE NEXT COUPLE OF DAYS AS A DRIER SOUTHWEST FLOW INCREASES OVER THE AREA. THIS WILL ALLOW TEMPERATURES TO CLIMB TO ABOVE NORMAL READINGS THROUGH THE WEEKEND. SLIGHTLY COOLER CONDITIONS ARE EXPECTED EARLY NEXT WEEK AS A STORM SYSTEM MOVES INTO THE WEST COAST. && .UPDATE...NO CHANGES TO THE FORECAST THIS MORNING. SURFACE OBS SHOW DRIER SURFACE CONDITIONS OVER THE WESTERN CWA WITH THE RICHER MOISTURE HANGING TOUGH ACROSS THE EASTERN AREAS WHERE WE ARE CURRENTLY FORECASTING THUNDERSTORM ACTIVITY FOR THIS AFTERNOON AND EVENING. THE MORNING LAS VEGAS SOUNDING INDICATED A COUPLE OF CAPS ALOFT BUT WITH PLENTY OF SUNSHINE TODAY, IT WILL ALLOW GOOD SURFACE HEATING AND THIS INHIBITION SHOULD BE OVERCOME BY EARLY AFTERNOON. && .AVIATION...FOR MCCARRAN...NORTHEAST WINDS WILL TURN MORE EASTERLY BY 18Z WITH SPEEDS AROUND 7-9KTS. THESE EASTERLY WINDS WILL PERSIST THROUGH MUCH OF THE AFTERNOON AND EVENTUALLY SHIFT TO THE SOUTHWEST AFTER SUNSET. FEW-SCT CLOUDS AROUND 10-12K FEET WITH ISOLATED THUNDERSTORMS POSSIBLE OVER THE SPRING MOUNTAINS WITH BETTER COVERAGE AFFECTING THE MORMON MESA AND PEACH SPRINGS APPROACH CORRIDORS. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...NORTHEAST WINDS WILL PERSIST THIS MORNING OVER CLARK AND MOHAVE COUNTIES WITH MOST AREAS SEEING NORTHEAST TO EAST WINDS AROUND 10KTS BY LATE MORNING AND AFTERNOON. THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON OVER MOHAVE COUNTY AND THE HIGHER TERRAIN OF CLARK AND EASTERN SAN BERNARDINO COUNTIES WITH CIGS POSSIBLY DOWN TO 8K FEET. OTHERWISE FEW-SCT 10-12K FEET EXPECTED. && .PREVIOUS DISCUSSION...230 AM PDT... .SHORT TERM...THROUGH SATURDAY NIGHT... ITS BEEN A FAIRLY ACTIVE NIGHT ACROSS LINCOLN COUNTY AS THUNDERSTORMS HAVE REMAINED FAIRLY PERSISTENT...ALTHOUGH IT LOOKS LIKE THINGS ARE STARTING TO QUIET DOWN AS OF 230 AM. THESE STORMS HAVE PUT DOWN A COUPLE OF OUTFLOW BOUNDARIES THAT WORKED THROUGH CLARK COUNTY AND HAVE SHIFTED WINDS TO THE NORTHEAST OVER MUCH OF THE AREA. THERE WERE A FEW SHOWERS THAT WORKED AS FAR SOUTH AS NORTHERN CLARK COUNTY...BUT QUICKLY DIED WITH THE LACK OF ANY REAL SUPPORT. PW VALUES ARE DOWN OVER MOST OF THE AREA FROM 24 HOURS AGO...BUT ENOUGH MOISTURE AND INSTABILITY WILL ALLOW FOR AT LEAST ISOLATED THUNDERSTORMS TO DEVELOP ONCE AGAIN OVER MAINLY MOHAVE AND THE HIGHER TERRAIN OF EASTERN SAN BERNARDINO AND CLARK COUNTIES. AFTERNOON HEATING WILL BE THE MAIN TRIGGER FOR ANY STORMS TO DEVELOP. A TROUGH DIGGING OFF THE WEST COAST WILL HELP INCREASE THE SOUTHWEST FLOW OVER THE AREA FRIDAY. STILL THINK THAT ENOUGH MOISTURE WILL RESIDE OVER THE FAR EASTERN AREAS OF THE CWA...BUT COVERAGE SHOULD BE LESS THAN THURSDAY. SOUTHWEST FLOW WILL INCREASE SATURDAY AND IS LIKELY TO PUSH ANY RESIDUAL MOISTURE EAST OF THE AREA LEAVING THE CWA DRY. WITH THE DRIER AIR TEMPERATURES WILL INCREASE OVER THE NEXT FEW DAYS WITH ABOVE NORMAL READINGS EXPECTED THROUGH THE WEEKEND. .LONG TERM...SUNDAY THROUGH THURSDAY. A LARGE SCALE TROUGH WILL SET UP ALONG THE WEST COAST AND WILL PERSIST THROUGH THE LONG TERM. THIS WILL RESULT IN A MAINLY DRY SOUTHWEST FLOW OVER THE FORECAST AREA WITH TEMPERATURES JUST A LITTLE ABOVE NORMAL. THERE WILL BE SOME HIGH CLOUDS AT TIMES BUT LOWER LEVEL MONSOON MOISTURE WILL LIKELY LINGER JUST EAST OF MOHAVE COUNTY. THE 00Z RUN OF THE GFS IS KEEPING THAT MONSOON MOISTURE A BIT FARTHER WEST...LAPPING AT EASTERN PORTIONS OF MOHAVE COUNTY BUT THE OTHER MODELS KEEP IT EAST SO I DID NOT ADD ANY THUNDERSTORM CHANCES BUT THAT TREND WILL NEED TO BE MONITORED. && .SPOTTER INFORMATION STATEMENT...SPOTTERS ARE ENCOURAGED TO REPORT ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES. && UPDATE/AVIATION...SALMEN PREV SHORT/LONG DISC...GORELOW/HARRISON FOR MORE FORECAST INFORMATION...SEE US ON OUR WEBPAGE: HTTP://WEATHER.GOV/LASVEGAS OR FOLLOW US ON FACEBOOK AND TWITTER
