What forecasters said that day
The local office's own words before this high wind watch went out, 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 this high wind watch went out at Apr 5, 4:34 PM PDT, 31 minutes earlier.
Area forecast discussion, Apr 5, 4:34 PM PDT, 31 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 434 PM PDT TUE APR 5 2011 .SYNOPSIS...A WEAK LOW PRESSURE SYSTEM WILL BRING INCREASED CLOUD COVER AND A SLIGHT CHANCE OF SHOWERS TO THE REGION LATE TONIGHT THROUGH WEDNESDAY. THIS WILL BE FOLLOWED BY A COLD AND POWERFUL STORM DROPPING DOWN ALONG THE WEST COAST. STRONG WINDS WILL DEVELOP AHEAD OF THIS SYSTEM ACROSS THE SOUTHERN SIERRA AND MUCH OF THE MOJAVE DESERT WEDNESDAY NIGHT AND THURSDAY. A GOOD CHANCE OF PRECIPITATION WITH DRAMATICALLY COOLER TEMPERATURES WILL BE IN STORE FOR THE ENTIRE REGION FRIDAY AND SATURDAY. CONDITIONS WILL IMPROVE LATE IN THE WEEKEND AS THE STORM MOVES EAST INTO THE ROCKIES. && .UPDATE...AVIATION...FOR MCCARRAN...GUSTY SOUTH-SOUTHWEST WINDS WILL CONTINUE THROUGH TONIGHT. SPEEDS WILL LESSEN SOMEWHAT OVERNIGHT WITH GUSTS UP TO 24 KTS EARLY THIS EVENING DROPPING TO AROUND 14 KTS LATER TONIGHT. WIND DIRECTION BECOMES A TOUGHER CHALLENGE BETWEEN 16Z AND 19Z WEDNESDAY AS SURFACE PRESSURE GRADIENTS RELAX AND THE DIRECTION BECOMES TOUGHER TO CALL. MODEL GUIDANCE SHOWS A SPREAD IN THE DIRECTION OF WINDS IN THIS TIME FRAME BETWEEN SOUTHWEST AND NORTHWEST OVER THE AIRPORT COMPLEX AND THUS OPTED TO GO VARIABLE IN DIRECTION GIVEN THE LOW CONFIDENCE IN ONE DIRECTION OVER ANOTHER. CLOUD BASES WILL LOWER OVERNIGHT WITH COVERAGE IN THE SCT-BKN RANGE. BASES WILL DROP TO BETWEEN 10K AND 15K FEET ON WEDNESDAY AFTERNOON WITH BASES AS LOW AS 8K FEET BY THE LATE AFTERNOON. THERE IS A SLIGHT CHANCE FOR SHOWERS OVER THE VALLEY WITH A BETTER CHANCE OVER THE NEARBY MOUNTAINS. ISOLATED TSRA WILL BE POSSIBLE MAINLY OVER THE MOUNTAINS. ANY SHRA OR TSRA WILL HAVE THE POTENTIAL TO PRODUCE GUSTY AND ERRATIC WINDS AND THUS A PROB30 WAS PLACED IN THE TAF TO ADDRESS THIS CONCERN FOR LATE WEDNESDAY AFTERNOON. THE THREAT OF SHRA/TSRA WILL WIND DOWN AFTER EARLY THURSDAY EVENING. ANOTHER SYSTEM WILL BRING THE POTENTIAL FOR STRONGER SOUTHWEST WINDS ON THURSDAY AFTERNOON AND EVENING...WITH GUSTS OVER 40 KTS POSSIBLE. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...WINDS WILL MAINLY BE GUSTY OUT OF THE SOUTHWEST TO WEST THIS EVENING WITH GUSTS OF 18-24 KTS AND LESSEN SOMEWHAT OVERNIGHT. A COLD FRONT DROPPING SOUTH ACROSS THE AREA TOMORROW WILL SHIFT WINDS TO THE NORTH BEHIND IT ACROSS THE SOUTHERN GREAT BASIN ON LATE WEDNESDAY MORNING AND LEAVE THEM NORTHERLY INTO WEDNESDAY AFTERNOON. CLOUD BASES WILL LOWER TONIGHT OVER THE AREA AHEAD OF THE FRONT WITH FURTHER LOWERING TAKING PLACE WEDNESDAY MORNING AND AFTERNOON OVER ALL AREAS EXCEPT INYO AND ESMERALDA COUNTY WHERE CLOUDS SHOULD SCATTER OUT BEHIND THE FRONT. AHEAD OF THE FRONT BASES WILL DROP AS LOW AS 6K-10K FEET. SCT SHRA AND ISOLATED TSRA ARE EXPECTED MAINLY WEDNESDAY AFTERNOON AND EVENING ACROSS LINCOLN...CLARK...MOHAVE... SOUTHERN NYE AND EASTERN SAN BERNARDINO COUNTIES. THE MAIN THREAT IN AND NEAR SHRA/TSRA WILL BE GUSTY AND ERRATIC WINDS. SMALL HAIL IS ALSO POSSIBLE. EVEN STRONGER WINDS ARE EXPECTED ACROSS THE AREA ON THURSDAY AFTERNOON AND EVENING WITH MANY AREAS SEEING GUSTS OVER 40 KTS AND MOUNTAIN WAVE POTENTIAL EXISTING TO THE LEE OF LARGER MOUNTAINS. && .PREVIOUS DISCUSSION... ISSUED AT 345 PM PDT TUE APR 5 2011 BY NATIONAL WEATHER SERVICE FLAGSTAFF AZ .SHORT TERM...TONIGHT THROUGH THURSDAY...SATELLITE IMAGERY THIS AFTERNOON SHOWS A WELL DEFINED WEST TO EAST ORIENTED FRONTAL BOUNDARY DRAPED FROM NORTHERN CA THROUGH NORTHERN NV AND FAR NORTHWEST UT. THIS BOUNDARY LIES WITHIN A BROAD TROUGH OF LOW PRESSURE ENCOMPASSING MUCH OF THE NORTHWESTERN U.S. A SECOND LOW PRESSURE SYSTEM IS ALSO SEEN SPINNING OFF THE SOUTHERN CA COAST THIS AFTERNOON. SOME HIGH LEVEL MOISTURE ASSOCIATED WITH THIS SYSTEM HAS ALREADY SPREAD HIGH CLOUDS INTO SOUTHERN PORTIONS OF THE STATE THIS AFTERNOON. THE FRONTAL BAND WILL GRADUALLY WORK SOUTHWARD ACROSS THE STATE TONIGHT MAKING ITS WAY INTO CENTRAL NV LATE THIS EVENING AND INTO THE LAS VEGAS AREA ABOUT MIDDAY WEDNESDAY. EXPECT BREEZY WINDS ALONG AND BEHIND THE FRONTAL PASSAGE...ALONG WITH A CHANCE FOR SHOWERS. WEDNESDAY AFTERNOON THE SOUTHERN CA LOW EJECTS TO THE NORTHEAST AND BRINGS A GOOD TAP OF SUBTROPICAL MOISTURE INTO FAR SOUTHERN PORTIONS OF THE FORECAST AREA. BELIEVE THIS IS WHERE THE BEST CHANCE FOR SHOWERS WILL BE WITH THIS SYSTEM...PARTICULARLY WEDNESDAY EVENING AS THE FRONTAL BAND PUSHES INTO MOJAVE COUNTY. THIS SYSTEM PUSHES EAST OF THE AREA WEDNESDAY NIGHT WITH LITTLE TIME TO RECOVER AS A MUCH COLDER AND DEEPER TROUGH SETTLES ALONG THE WEST COAST. THIS SECOND AND MUCH STRONGER SYSTEM PUSHES A VERY STRONG COLD FRONT INTO THE REGION LATE WEDNESDAY NIGHT THROUGH THURSDAY. VERY STRONG PRE-FRONTAL GRADIENT FLOW DEVELOPS WITH MODELS CONTINUING TO SUGGEST 45-55 KT 700 MB WIND SPEEDS. THE STRONGEST WINDS WILL DEVELOP EARLY THURSDAY MORNING AND CONTINUE TO INCREASE THROUGHOUT THE DAY...ESPECIALLY ACROSS INYO...SAN BERNARDINO...CLARK...AND MOJAVE COUNTIES. WIND HIGHLIGHTS LOOK VERY LIKELY AT THIS POINT BUT WILL ALLOW FURTHER SHIFTS TO DETERMINE THE EXACT DETAILS. IN ADDITION TO THE WIND...THIS STRONG STORM SYSTEM WILL SPREAD A CHANCE FOR SHOWERS ACROSS THE AREA THURSDAY AND THURSDAY NIGHT. SNOW LEVELS THURSDAY WILL INITIALLY BE AROUND 5500-6500 FEET...BUT WILL DROP SHARPLY BEHIND THE FRONT TO NEAR 3000-4000 FEET BY EARLY FRIDAY MORNING. .LONG TERM...FRIDAY THROUGH WEDNESDAY...UNSETTLED WEATHER AND MUCH COOLER TEMPERATURES WILL CONTINUE FRIDAY AND SATURDAY AS THE UPPER LEVEL COLD POOL MOVES DIRECTLY OVERHEAD. EXPECT A GOOD CHANCE FOR RAIN AND SNOW SHOWERS WITH DAYTIME TEMPERATURES RUNNING 15 TO 20 DEGREES COLDER THAN NORMAL. FAIR WEATHER RETURNS LATE IN THE WEEKEND AS HIGH PRESSURE BUILDS OVER THE WESTERN STATES...WITH TEMPERATURES RECOVERING TO NEAR NORMAL RANGES. LONG RANGE MODELS INDICATE ANOTHER SHORTWAVE PASSING THROUGH THE GREAT BASIN EARLY NEXT WEEK FOR ANOTHER ROUND OF BREEZY WEATHER AND A SLIGHT CHANCE FOR SHOWERS. && .VEF WATCHES/WARNINGS/ADVISORIES...
