AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
131 PM PDT TUE JUL 8 2014

.SYNOPSIS...MOISTURE WILL REMAIN ACROSS THE REGION RESULTING IN A
CHANCE OF THUNDERSTORMS FOR MOST OF THE WEEK. A FEW STORMS COULD
PRODUCE VERY HEAVY RAIN LEADING TO LOCALIZED FLASH FLOODING.
&&

.SHORT TERM [TONIGHT THROUGH THURSDAY NIGHT]...
SLOW START TO THE CONVECTION TODAY AS INSTABILITY IS A BIT LESS THAN
YESTERDAY. THE PRIMARY AREAS WHERE THINGS ARE STARTING TO POP UP ARE
IN MOHAVE COUNTY AND WESTERN INYO OVER THE SIERRAS. WILL NEED KEEP
A CLOSE EYE OVER THE ENTIRE CENTER PORTIONS OF THE CWA THIS
AFTERNOON. FOR LAS VEGAS AND COLORADO RIVER VALLEY...A LATE START TO
THE STORMS CAN BE EXPECTED AGAIN SIMILAR TO THE LAST FEW DAYS. THE
GFS CONTINUES TO AGGRESSIVELY PUSH DRIER AIR NORTHEAST INTO THE AREA
WEDNESDAY BUT A MENTION OF THUNDERSTORMS OVER NORTHWEST
ARIZONA...SOUTHERN NEVADA AND PORTIONS OF INYO AND EASTERN SAN
BERNARDINO HAVE BEEN LEFT IN THE FORECAST AS SOME UNCERTAINTY
REMAINS WITH THAT SOLUTION.

.LONG TERM [FRIDAY THROUGH SUNDAY]...
HERE IS DECENT AGREEMENT THAT THE DRYING TREND WILL CONTINUE FOR
LATE IN THE WEEK WITH THUNDERSTORM CHANCES BASICALLY EAST OF LAS
VEGAS BY FRIDAY. NO CHANGES WERE MADE TO THE FORECAST FOR SATURDAY
THROUGH MONDAY WITH THUNDERSTORM CHANCES LIMITED TO MOHAVE COUNTY AS
THE AREA LOOKS TO REMAIN IN A BATTLE ZONE BETWEEN A FAIRLY DRY
SOUTHWEST FLOW AND A MORE MOIST SOUTHEAST FLOW. THAT IS NOT UNUSUAL
FOR OUR FORECAST AREA DURING MONSOON SEASON AND THE DRY AIR RARELY
PUSHES ALL THE WAY EAST THROUGH MOHAVE COUNTY.
&&

.AVIATION...FOR MCCARRAN...NORTHERLY WINDS ACROSS THE VALLEY WILL
PREVAIL EARLY THIS AFTERNOON AND HOVER CLOSE TO THE 10KT THRESHOLD.
THIS MAY FAVOR A CONFIGURATION 2 OR 3 UNTIL WINDS GO SOUTHWEST EARLY
THIS EVENING. THUNDERSTORMS ARE FIRING OVER THE SPRING MOUNTAINS AND
HIGHER TERRAIN IN THE VALLEY. STORMS ARE NOT EXPECTED AT THE
TERMINAL....BUT IT A STRAY STORM ROLLS IN IT WILL BE LATE SIMILAR TO
YESTERDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ACROSS
ENTIRE AREA THROUGH THIS EVENING. ERRATIC AND GUSTY WINDS.
&&

.SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT EXPECTED
AT THIS TIME. HOWEVER...SPOTTERS ARE ENCOURAGED TO REPORT ANY
SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.
