AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
217 PM PDT TUE AUG 19 2014

.SYNOPSIS...A LOW PRESSURE SYSTEM DROPPING DOWN THE WEST COAST WILL
ACT UPON MONSOON MOISTURE IN PLACE LEADING TO A CHANCE OF
THUNDERSTORMS OVER SOUTHEAST CALIFORNIA...SOUTHERN NEVADA AND
NORTHWEST ARIZONA AT LEAST THROUGH WEDNESDAY. TEMPERATURES WILL
REMAIN SEVERAL DEGREES BELOW NORMAL.
&&

.SHORT TERM...THROUGH WEDNESDAY NIGHT...BUSY AFTERNOON. EARLY
MORNING THUNDERSTORMS WORKED OVER LINCOLN AND EASTERN MOHAVE
COUNTIES...DRY AIR PUNCHING IN FROM THE WEST HAS CLEARED OUT MOST OF
SAN BERNARDINO COUNTY...AND THE NARROW WEDGE IN BETWEEN OVER FAR
EASTERN SAN BERNARDINO...SOUTHERN CLARK AND WESTERN MOHAVE HAS LIT
UP WITH BIG STORMS THIS AFTERNOON. AS THE MAIN LOW OVER THE WEST
COAST DIGS FARTHER SOUTH WEDNESDAY...SOUTHWEST FLOW OVER OUR AREA
WILL BACK AROUND TO THE SOUTH...ALLOWING THE MOISTURE TO SLOSH BACK
TO THE WEST AND BRING THUNDERSTORM CHANCES BACK TO AREAS SOUTHEAST
OF A LINE FROM BARSTOW TO HIKO. THE SIERRA NEVADA RANGE MAY ALSO SEE
A FEW STORMS THANKS TO THE INFLUENCE OF THE LOW. SOME STORMS ARE
LIKELY TO PERSIST THROUGH WEDNESDAY NIGHT OVER THE EASTERN CWA WITH
THE LOW NEARBY.

.LONG TERM...THURSDAY THROUGH TUESDAY...VERY LITTLE CHANGE TO THE
PREVIOUS THINKING. MODELS HAVE COME INTO SLIGHTLY BETTER AGREEMENT
BRINGING AN UPPER LEVEL LOW ACROSS THE AREA IN THE LATE WEDNESDAY
THROUGH THURSDAY TIMEFRAME. THURSDAY IS EXPECTED TO BE THE MOST
ACTIVE OF THE LONG TERM PERIOD WITH A GENERAL DRYING TREND
THEREAFTER. I DID EXPAND POPS A BIT FURTHER WEST ON THURSDAY TO
ACCOUNT FOR THE SLIGHTLY SLOW ECMWF AND NAM SOLUTIONS. BASICALLY
KEEPING POPS IN EAST OF A PIOCHE...MT. CHARLESTON...MORONGO VALLEY
LINE AND THE BEST CHANCES OVER MOHAVE COUNTY AND THE CLARK COUNTY
MOUNTAINS. KEPT IN A MENTION OF SHOWERS/THUNDERSTORMS OVER
SOUTHEASTERN MOHAVE COUNTY THURSDAY NIGHT AS ECMWF PUSHES THE LOW
OVER THE AREA.

FOR FRIDAY AND SATURDAY KEPT ONLY A SLIGHT CHANCE OF THUNDERSTORMS
MENTIONED OVER MOHAVE COUNTY TO ACCOUNT FOR ANY LINGERING MOISTURE.
OTHERWISE EXPECT DRIER CONDITIONS AND A WARMING TREND INTO EARLY
NEXT WEEK. THERE DOESN'T APPEAR TO BE A STRONG SIGNAL OF RETURNING
MOISTURE THROUGH THE BEGINNING OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...STRONG TO SEVERE THUNDERSTORMS WILL
AFFECT AREAS SOUTHEAST OF THE TERMINAL THIS EVENING AND
OVERNIGHT...WHICH COULD PRODUCE OUTFLOW WINDS AT THE TERMINAL AT
SOME POINT. THUNDERSTORM CHANCES WILL MOVE BACK INTO ALL APPROACH
CORRIDORS WEDNESDAY...WITH THE LOWEST CHANCE IN THE BEATTY CORRIDOR.
THERE WILL ALSO BE A SLIGHT CHANCE AT THE TERMINAL.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...STRONG TO SEVERE THUNDERSTORMS WILL AFFECT AREAS NEAR
AND EAST OF THE COLORADO RIVER THIS EVENING AND OVERNIGHT...WITH
EXTREMELY HEAVY RAINFALL AND HIGH WINDS THE MAIN THREATS.
THUNDERSTORM CHANCES WILL AFFECT AREAS ROUGHLY EAST OF A LINE FROM
BARSTOW TO HIKO ON WEDNESDAY.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTERS SHOULD REPORT INSTANCES OF
FLASH FLOODING...STRONG GUSTY WINDS...HAIL...AND BLOWING DUST
THROUGH WEDNESDAY.
