The episode as NWS VEF wrote it up.
One man died in Las Vegas of heat related causes.
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 18, 8:18 AM PST, 4 hours 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 918 AM PDT MON AUG 18 2014 .SYNOPSIS...A LOW PRESSURE SYSTEM DROPPING DOWN THE WEST COAST WILL HELP DRAW MONSOON MOISTURE NORTH...LEADING TO A CHANCE OF THUNDERSTORMS OVER EASTERN CALIFORNIA...SOUTHERN NEVADA AND NORTHWEST ARIZONA TODAY INTO TUESDAY. TEMPERATURES WILL COOL SOME EACH DAY INFLUENCED BY THE MOISTURE AND NEARBY LOW PRESSURE SYSTEM. && .UPDATE...THUNDERSTORMS ROUGHLY ALONG INTERSTATE 40 FROM ESSEX TO NORTH OF YUCCA WERE MOVING NORTH AND SLOWLY WEAKENING. RAISED POPS AND CLOUD COVER IN THE PATH OF THE STORMS. && .PREV DISCUSSION... 252 AM PDT MON AUG 18 2014 .SHORT TERM...THROUGH TUESDAY NIGHT AN OUTFLOW BOUNDARY OUT OF SOUTHWEST ARIZONA MOVED THROUGH LAKE HAVASU CITY AROUND MIDNIGHT. THE BOUNDARY HAS CONTINUING TO PUSH WEST THROUGH SOUTHERN SAN BERNARDINO COUNTY, ALTHOUGH WESTWARD MOMENTUM LOOKS TO BE SLOWING AS IT NEARS THE MORONGO BASIN. ELSEWHERE SKIES ARE CLEAR. MOISTURE OVER ARIZONA WILL CONTINUE TO FLOW NORTHWARD INTO THE MOJAVE DESERT AND SOUTHERN GREAT BASIN SOUTHEAST TODAY AROUND HIGH PRESSURE CENTERED NEAR THE FOUR CORNERS. A MID-LEVEL SHORTWAVE TROUGH NEAR THE SOUTHERN CALIFORNIA COAST WILL SLOWLY SHIFT INLAND ACROSS THE AREA TONIGHT IN RESPONSE TO A CLOSED LOW LOW DROPPING DOWN THE PAC NW COAST. THIS SHORTWAVE TROUGH WILL PROVIDE SOME ADDITIONAL DYNAMICS IN THE FORM OF DIVERGENCE ALOFT ASSOCIATED WITH A 70 KNOT JET OVERHEAD. GOING TO KEEP ANY MENTION OF ISOLD/SCTD THUNDERSTORMS EAST OF A YUCCA VALLEY-PAHRUMP-RACHEL LINE TODAY. THE NORTHWEST CWA WILL STAY THUNDERSTORM FREE. DID INCREASE POPS FOR LINCOLN, ERN CLARK, ERN SAN BERNARDINO AND MOHAVE COUNTIES TONIGHT INTO TUESDAY AS HI-RES MODELS SIMILAR SHOWING GOOD CLUSTERING FOR THUNDERSTORM POTENTIAL. WITH UPPER LOW MOVING SOUTH OVER CENTRAL CALIFORNIA TUESDAY AFTERNOON DECIDED TO INTRODUCE A SLIGHT CHANCE OF THUNDERSTORMS TO THE EASTERN SIERRA SLOPES. LOWERING HEIGHTS, HIGHER HUMIDITY/CLOUD COVER WILL PRODUCE NEAR NORMAL TEMPERATURES TODAY FOLLOWED BY BELOW NORMAL VALUES TUESDAY. .LONG TERM...WEDNESDAY THROUGH MONDAY NIGHT. THIS IS NOT THE HIGHEST CONFIDENT OF FORECASTS FOR THE LATE WEEK PERIOD AS THE LATEST OPERATIONAL MODELS CONTINUE TO SHOW A LARGE SPREAD IN HOW THEY HANDLE THE MAJOR FEATURES IN THIS PERIOD. A MID/UPPER LEVEL LOW IS FORECAST TO DROP INTO SOCAL ON WEDNESDAY WHICH WILL CONTINUE TO PULL MOISTURE ON NORTH. HOW FAR WEST THIS MOISTURE GETS IS QUESTIONABLE BUT GIVEN THE POSITION OF THE LOW NEAR LOS ANGELES IT IS POSSIBLE SHOWERS AND THUNDERSTORMS COULD DEVELOP AS FAR WEST AS A MORONGO VALLEY TO MT CHARLESTON TO PIOCHE LINE AND A SLIGHT CHANCE FOR THUNDERSTORMS WAS PLACED IN FROM HERE ON EAST. WORTH WATCHING WILL BE THE POTENTIAL FOR A MOIST-DRY BOUNDARY (OR A SO-CALLED DESERT DRY LINE) WHICH TENDS TO SERVE AS FOCUS FOR SHOWERS AND THUNDERSTORMS TO DEVELOP. THE MAIN ISSUE IS IN THE THURSDAY THROUGH SATURDAY PERIOD AS THE AFOREMENTIONED LOW IS EITHER PUSHED EAST BY A MID/UPPER LEVEL TROUGH THAT DROPS INTO NORTHERN NEVADA OR IS NOT PICKED UP AND FLOATS AROUND EITHER OFF TO THE WEST (GEM) OR IS SLOWER TO EJECT (ECMWF AND DGEX) VERSUS THE FASTER OPERATIONAL GFS. AT THIS TIME, CONFIDENCE IS NOT THE HIGHEST IN ANY ONE SOLUTION. THE FORECAST THUS CONTINUES A BLEND OF THE VARIOUS SOLUTIONS, KEEPING A CHANCE FOR SHOWERS AND THUNDERSTORMS IN FOR MAINLY THE AFTERNOON AND EVENING HOURS SOUTH OF INTERSTATE 15 WITH THE HIGHEST CHANCES IN MOHAVE COUNTY. BY SUNDAY, WE SHOWED A DRYING TREND AS ALL MODELS SHOW THE LOW OFF EITHER WELL ENOUGH TO THE WEST OR EAST. HIGH TEMPS WERE LOWERED SEVERAL DEGREES DUE TO THE LOW AND EXPECTED INCREASED CLOUD COVER FROM WEDNESDAY THROUGH FRIDAY WITH HIGHS AS MUCH AS 6 TO 9 DEGREES BELOW NORMAL. TEMPS SHOULD THEN WARM BACK CLOSER TO NORMAL OVER THE WEEKEND AND BASED ON FORECAST SOUNDINGS, WE WENT ABOVE STATISTICAL GUIDANCE AND WITH THE WARMER END OF BIAS CORRECTED CONS MODELS. DEWPOINTS WERE ALSO RAISED SEVERAL DEGREES TO BETTER BLEND WITH NEIGHBORING OFFICES. .AVIATION...FOR MCCARRAN...THERE IS A SLIGHT CHANCE THAT THUNDERSTORMS WILL DEVELOP NEAR THE TERMINAL AREA THIS AFTERNOON AND EVENING BUT CONFIDENCE IS NOT HIGH ENOUGH TO INCLUDE IN THE TAF. OTHERWISE...EXPECT PERIODS OF EAST TO SOUTHEAST WINDS IN THE LATE MORNING AND EARLY AFTERNOON ALONG WITH INCREASING CLOUDS ABOVE 10 KFT AGL. EVEN IF STORMS ARE NOT NEAR THE TERMINALS WINDS COULD BECOME GUSTY AND ERRATIC IN DIRECTION. THERE WILL BE CHANCES FOR THUNDERSTORMS TODAY IN ALL CORRIDORS AND TUESDAY IN THE MORMON MESA AND PEACH SPRINGS CORRIDORS. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...ISOLATED/SCATTERED THUNDERSTORMS CAN BE EXPECTED TODAY THROUGH TUESDAY OVER EASTERN SAN BERNARDINO COUNTY CALIFORNIA... SOUTHEAST NEVADA AND NORTHWEST ARIZONA. CEILING MAY LOWER TO 5-7K FT IN THUNDERSTORMS ESPECIALLY OVER NORTHWEST ARIZONA. WINDS WILL FOLLOW TYPICAL DIURNAL TRENDS EXCEPT BE GUSTY AND ERRATIC NEAR STORMS .SPOTTER INFORMATION STATEMENT...SPOTTERS SHOULD REPORT INSTANCES OF FLASH FLOODING...STRONG GUSTY WINDS...HAIL...AND BLOWING DUST TODAY THROUGH TUESDAY. && MORGAN/PIERCE/STACHELSKI FOR MORE FORECAST INFORMATION...SEE US ON OUR WEBPAGE: HTTP://WEATHER.GOV/LASVEGAS OR FOLLOW US ON FACEBOOK AND TWITTER
