AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
320 PM PDT TUE AUG 22 2006

.SYNOPSIS...A DEVELOPING SOUTHEAST FLOW WILL PULL MOIST AND UNSTABLE
AIR INTO THE MOJAVE DESERT AND SOUTHERN GREAT BASIN FROM
ARIZONA...BRINGING ISOLATED TO SCATTERED THUNDERSTORMS THROUGH
WEDNESDAY. WEAK WESTERLY FLOW WILL THEN RETURN...PUSHING THE
MOISTURE BACK TOWARD ARIZONA THURSDAY AND FRIDAY. TEMPERATURES WILL
REMAIN A FEW DEGREES ABOVE NORMAL.
&&

.SHORT TERM...THUNDERSTORMS HAD DEVELOPED OVER THE EXPECTED AREA
THIS AFTERNOON...SOUTHEAST OF I-15...WITH THE EXCEPTION OF THE STRAY
STORM OVER THE SHEEP RANGE. ISOLATED CELLS OVER SOUTHERN CLARK
COUNTY WERE MOVING SLOWLY EAST-NORTHEAST AND SHOWED NO GOOD
INDICATION OF DEVELOPMENT TOWARD THE LAS VEGAS VALLEY. LEFT THE
MENTION OF STORMS OUT OF LAS VEGAS THIS EVENING. THUNDERSTORMS ALONG
THE ARIZONA RIM COUNTRY COULD BE SEEN PROPAGATING WESTWARD. MOIST
AND UNSTABLE AIR IS IN PLACE OVER SOUTHERN MOHAVE COUNTY AND SHOULD
FUEL SCATTERED THUNDERSTORMS THIS EVENING. THE 12Z NAM APPEARS TO
HAVE A LITTLE BETTER HANDLE ON THE CURRENT SITUATION THAN THE GFS
AND PREFER ITS SOLUTION WHICH BASICALLY INDICATES LITTLE CHANGE TO
THE PREVIOUS TRENDS FOR WEDNESDAY. MOISTURE CONTINUES TO SPREAD
NORTHWEST OVERNIGHT AND ISOLATED THUNDERSTORMS SHOULD DEVELOP OVER
CLARK...LINCOLN AND SOUTHERN NYE COUNTIES WEDNESDAY AFTERNOON.
SCATTERED THUNDERSTORMS SHOULD DEVELOP OVER MOHAVE AND SOUTHERN SAN
BERNARDINO COUNTIES. BOTH THE NAM AND GFS SHOW WESTERLY FLOW
BEGINNING TO SPREAD INTO SOUTHEAST CALIFORNIA/NEVADA THURSDAY AND
STORMS SHOULD BE CONFINED MAINLY TO MOHAVE COUNTY THURSDAY AFTERNOON.

.LONG TERM...THINKING VIRTUALLY UNCHANGED FROM LAST FORECAST.
MOISTURE LOOKS TO HANG AROUND THE SOUTH AND EAST PARTS OF THE
FORECAST AREA AS A BROAD TROUGH SETS UP WEST OF AREA FOR MOST OF THE
EXTENDED. FLOW DOES NOT LOOK STRONG ENOUGH TO MOVE THE MOISTURE AWAY
FROM AREA. HENCE THE AFTERNOON POPS IN THE FAVORED AREAS OF
LINCOLN...MOHAVE...THE SOUTH AND EAST FRINGES OF CLARK...AND
SOUTHERN SAN BERNARDINO COUNTIES THROUGH THE EXTENDED. TEMPERATURE
GUIDANCE RUNS COOLER THAN NORMAL TEMPERATURES AND CURRENT FORECAST
SO LOWER TEMPERATURES SLIGHTLY TO BE BETWEEN THE TWO. &&

.AVIATION...ISOLATED THUNDERSTORMS IN THE PEACH SPRINGS DAGGETT
CORRIDORS WILL OCCUR UNTIL AROUND 04Z THIS EVENING. TAFS AND TWEBS
ADEQUATELY DESCRIBE EXPECTED WEATHER CONDITIONS FOR AREA TERMINALS.
SEE TAFS FOR KLAS... KVGT... KDRA... KBIH... KDAG... KEED... FOR
DETAILS.
