AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1056 AM PDT WED AUG 26 2015

.SYNOPSIS...THERE WILL BE ENOUGH MOISTURE REMAINING OVER THE AREA
TODAY FOR ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS AFFECTING
MAINLY MOHAVE...CLARK...LINCOLN AND EASTERN SAN BERNARDINO COUNTIES.
THUNDERSTORM CHANCES WILL DECREASE THURSDAY WITH ADDITIONAL DRYING
EXPECTED FRIDAY THROUGH THE WEEKEND AS A INCREASING SOUTHWEST FLOW
SETS UP OVER THE AREA.
&&

.UPDATE...A FEW SHOWERS AND AN ISOLATED THUNDERSTORM DEVELOPED OVER
ESMERALDA COUNTY. SO...WENT AHEAD AND ADDED SLIGHT/CHANCE POPS TO
THE COUNTY. -SALMEN-
&&

.PREV UPDATE...951 AM PDT...MONSOON MOISTURE INCREASED FAIRLY
SIGNIFICANTLY FROM 24 HRS AGO WITH PWAT VALUES OF .84 INCHES OFF THE
LAS VEGAS SOUNDING TUESDAY MORNING TO 1.55 INCHES THIS MORNING.
EXTENSIVE CLOUD COVER ACROSS MUCH OF THE AREA THIS MORNING BUT HAS
BEGUN TO ERODE SOMEWHAT OVER THE NORTHWEST CWA. LIGHT SHOWERS WERE
NOTED ON RADAR OVER PORTIONS OF EASTERN SAN BERNARDINO COUNTY AND
THE SOUTHERN PORTIONS OF CLARK COUNTY. AT 945 AM...LIGHT SHOWERS
WERE NOTED IN THE SOUTHERN PORTIONS OF THE LAS VEGAS VALLEY. EXPECT

SALMEN
&&

.PREVIOUS DISCUSSION...245 AM PDT...

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...A FEW AREAS OF SHOWERS
REMAIN THIS MORNING OVER PORTIONS OF NORTHERN MOHAVE...WESTERN CLARK
AND EASTERN SAN BERNARDINO COUNTY WHICH ARE BEING AIDED BY A COUPLE
OF DISTURBANCES MOVING THROUGH THE REGION. THESE ARE EXPECTED TO
LAST THROUGH MUCH OF THE MORNING...BUT ONLY PRODUCING SOME LIGHT
SHOWERS. IT LOOKS LIKE WE WILL SEE MORE SHOWERS AND THUNDERSTORMS
DEVELOP THIS AFTERNOON OVER MAINLY THE EASTERN HALF OF THE AREA AS
FAIRLY DEEP MOISTURE REMAINS IN PLACE. ALTHOUGH THE MAIN DISTURBANCE
WILL LIFT NORTH THE MODELS ARE INDICATING ANOTHER WEAK DISTURBANCE
PUSHING NORTH THROUGH MOHAVE COUNTY DURING THE AFTERNOON. THIS
SHOULD HELP AID IN THE DEVELOPMENT OF AFTERNOON SHOWERS AND
THUNDERSTORMS...ESPECIALLY IF WE SEE MORE SUN THEN WE DID YESTERDAY.
BY THURSDAY MOISTURE AND INSTABILITY WILL REMAIN OVER THE EASTERN
HALF OF THE AREA...BUT WITH THE LACK OF ANY SIGNIFICANT DISTURBANCE
THUNDERSTORMS THAT DO DEVELOP WILL GENERALLY BE TERRAIN DRIVEN AND
WINDS THROUGH ABOUT 500MB ARE EXPECTED TO BE FAIRLY LIGHT SO MOST
WILL REMAIN ANCHORED TO THE HIGHER TERRAIN. DRIER CONDITIONS WILL
RETURN FRIDAY AS A SOUTHWEST FLOW STARTS TO INCREASE. THIS WILL
LEAVE ONLY THE FAR EASTERN PORTIONS OF THE FORECAST AREA SEEING THE
BEST CHANCE OF AFTERNOON THUNDERSTORMS. TEMPERATURES WILL RUN CLOSE
TO NORMAL WEDNESDAY AND THURSDAY...BUT WITH BETTER MIXING FRIDAY
READINGS ARE EXPECTED TO JUMP A FEW DEGREES.

.LONG TERM...SATURDAY THROUGH WEDNESDAY.

DRY SOUTHWEST FLOW WILL BE IN THE PROCESS OF SCOURING MOISTURE OUT
OF THE AREA FROM WEST TO EAST SATURDAY...AS A SHORTWAVE ASSOCIATED
WITH AN UPPER LEVEL LOW OFF OF THE PACIFIC NORTHWEST COAST SWEEPS
ACROSS THE NORTHERN GREAT BASIN. THIS WILL INTRODUCE DRIER...COOLER
AND PERIODICALLY BREEZY CONDITIONS ACROSS THE REGION. SUNDAY THROUGH
MONDAY...OPERATIONAL MODEL GUIDANCE IS IN GOOD AGREEMENT IN BRINGING
A SECOND SHORTWAVE ACROSS THE GREAT BASIN...INCREASING SOUTHWESTERLY
WINDS AND FURTHER COOLING TEMPERATURES DOWN TO SEASONAL NORMALS
THROUGH THE END OF THE PERIOD. THOUGH MODELS CONTINUE TO SHOW A
QUIET EXTENDED PERIOD IN TERMS OF WEATHER...BOTH THE LATEST GFS AND
ECMWF DO HINT AT SOME MOISTURE RETURN OVER AT LEAST MOHAVE COUNTY ON
TUESDAY AND WEDNESDAY AHEAD OF A THIRD...BROAD SHORTWAVE THAT IS
PROGGED TO BE APPROACHING THE REGION. THIS WILL BE WORTH KEEPING AN
EYE ON AS THE DETAILS BECOME CLEARER IN THE COMING DAYS.
&&

.AVIATION...FOR MCCARRAN...A FEW MAINLY LIGHT SHOWERS WILL HANG
AROUND PORTIONS OF CLARK COUNTY THIS MORNING WITH THE BEST
CONCENTRATION OVER NORTHERN MOHAVE COUNTY AFFECTING THE MORMON MESA
APPROACH CORRIDOR. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP
THIS AFTERNOON AFFECTING AREAS MAINLY EAST OF LAS VEGAS...BUT SEEING
A THUNDERSTORM AT THE TERMINAL CAN NOT BE RULED OUT. CLOUDS SCT-
BKN120 THROUGH MUCH OF THE DAY...BUT MAY LOWER TO AROUND 8K THIS
AFTERNOON NEAR ANY STORMS. EAST WINDS 5-7KTS THIS MORNING WILL
TRANSITION TO SOUTHEAST 7-9KTS THIS AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...FEW LIGHT TO MODERATE SHOWERS THIS MORNING OVER
MOHAVE...CLARK AND EASTERN SAN BERNARDINO COUNTIES WITH CIGS AROUND
10-12K FEET. ADDITIONAL SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS
AFTERNOON OVER THE EASTERN HALF OF THE AREA WITH CLOUDS AROUND 8-10K
FEET. WINDS WILL GENERALLY BE EAST TO SOUTHEAST 7-10KTS THROUGH
MUCH OF THE DAY.
