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 23, 6:30 PM PST, 5 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 730 PM PDT SUN AUG 23 2015 .SYNOPSIS...HAZY CONDITIONS WILL PERSIST FOR SEVERAL MORE DAYS ACROSS THE OWENS VALLEY AND PARTS OF ESMERALDA COUNTY DUE TO SMOKE FROM CALIFORNIA WILDFIRES. OTHERWISE...SLIGHT CHANCES OF THUNDERSTORMS EXIST IN MOHAVE COUNTY MONDAY BEFORE MOISTURE INCREASES ACROSS MUCH OF THE REGION TUESDAY AND WEDNESDAY FOR A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS. SLOW DRYING IS EXPECTED THURSDAY THROUGH THE WEEKEND. && .UPDATE...SKIES HAVE CLEARED OUT RAPIDLY THIS EVENING AS THUNDERSTORM ACTIVITY ACROSS MOHAVE COUNTY HAS DIMINISHED RAPIDLY WITH SUNSET. FAIR WEATHER EXPECTED TONIGHT WITH JUST SOME HIGH CLOUDS ACROSS OUR NORTHWEST ZONES AND AREAS OF SMOKE AND HAZE NEAR THE OWENS VALLEY. THE FORECAST IS IN GOOD SHAPE AND OTHER THAN SOME ADJUSTMENTS TO SKY COVER...NO UPDATES ARE PLANNED THIS EVENING. -OUTLER- && .SHORT TERM...THROUGH WEDNESDAY NIGHT. THUNDERSTORMS THAT DEVELOPED MID-DAY BETWEEN THE HUALAPAI MOUNTAINS AND VALENTINE HAVE HAVE WEAKENED. ADDITIONAL DEVELOPMENT THE REST OF THIS AFTERNOON INTO EARLY EVENING DOES NOT LOOK FAVORABLE BUT LEFT A SLIGHT CHANCE MENTION NEAR THE COUNTY BORDER WITH COCONINO AND YAVAPAI COUNTIES. RESIDUAL MOISTURE AND INSTABILITY WILL LEAD TO ANOTHER DAY OF THUNDERSTORMS PRIMARILY AFFECTING THE HIGHER TERRAIN OF MOHAVE COUNTY. DRY WITH CONTINUED ABOVE NORMAL TEMPERATURES ELSEWHERE MONDAY. CHALLENGING ASPECT OF FORECAST WILL BE TUESDAY AND WEDNESDAY. MODELS CONTINUE TO INDICATE A LOBE OF VORTICITY ROTATING AROUND THE WESTERN EDGE OF THE ANTICYCLONE TO OUR EAST. LOBE PROGGED TO LIFT NORTH ACROSS THE AREA TUESDAY BEFORE BEING PICKED UP BY SOUTHWEST FLOW AND QUICKLY LIFTING NORTHEAST INTO NORTHERN UTAH BY 12Z WEDNESDAY. ALONG WITH THE VORTICITY LOBE...DEEPER MONSOON MOISTURE POOLED OVER THE SOUTHERN DESERTS OF ARIZONA WILL ADVECT NORTHWARD AS WELL. THERE ARE SOME TIMING DIFFERENCES WITH THE MOISTURE BUT LEANING TOWARD A BLEND OF THE 12Z GFS/ECMWF. THIS PLACES DEEPER MOISTURE MAINLY ALONG AND SOUTH OF INTERSTATE 40 MONDAY NIGHT BEFORE SURGING NORTHWARD INTO CLARK COUNTY TUESDAY WHILE LINGERING INTO WEDNESDAY. THERE ARE TWO WAYS THE FORECAST COULD PAN OUT FOR TUESDAY WHICH IS THE CHALLENGE. THE FIRST IS A CONSIDERABLE AMOUNT OF CLOUDS/SHOWERS COULD DEVELOP EARLY WHICH WOULD ACT TO INHIBIT STRONG CONVECTION THUS LIMITING THE FLASH FLOOD THREAT. THE SECOND IS CLOUDINESS IS DELAYED ALLOWING FOR STRONG SURFACE HEATING HELPING DEVELOP STRONG CONVECTION ALONG WITH A HIGHER FLASH FLOOD THREAT. RIGHT NOW...THE FIRST SCENARIO LOOKS MORE PROBABLE. USED OF BLEND OF GUIDANCE FOR THE HIGH ON TUESDAY WITH LATEST GFS LOOKING TOO HIGH. WILL BE TAKING A HARD LOOK FOR THE NEED OF A FLASH FLOOD WATCH TOMORROW. MOISTURE THAT COMES UP TUESDAY WILL STILL BE AROUND WEDNESDAY WHICH MAY ACTUALLY MAKE WEDNESDAY MORE INTERESTING...ESPECIALLY IF WE GET MORE SUNSHINE. .LONG TERM...THURSDAY THROUGH SUNDAY. A DRYING TREND IS EXPECTED WITH SOUTHWESTERLY FLOW RETURNING TO THE REGION. FOR THURSDAY THERE WILL STILL BE ENOUGH MOISTURE TO WARRANT A SLIGHT CHANCE IN THE HIGHER TERRAIN OF MOHAVE AND LINCOLN COUNTIES AND PERHAPS EVEN THE SPRING MOUNTAINS AND SHEEP RANGE OF CLARK. BY FRIDAY MOSTLY DRY CONDITIONS ARE EXPECTED AREA WIDE. THIS DRYING WILL ALSO BE ACCOMPANIED BY TEMPERATURES WARMING TO SEVERAL DEGREES ABOVE NORMAL BY THE WEEKEND. && .AVIATION...FOR MCCARRAN...WINDS ARE EXPECTED TO FOLLOW TYPICAL DIURNAL TRENDS THROUGH MONDAY WITH OCCASIONALLY GUSTY SOUTHEAST WINDS TRANSITIONING TO SOUTHWEST WINDS DURING THE LATE AFTERNOON/EARLY EVENING.
