AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
944 PM PDT FRI JUL 19 2013

.SYNOPSIS...ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS PORTIONS OF
EASTERN SAN BERNARDINO AND SOUTHERN MOHAVE COUNTIES OVERNIGHT.
THUNDERSTORM COVERAGE WILL SPREAD WEST SATURDAY AND SUNDAY WITH
ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED IN MOHAVE...CLARK...SAN
BERNARDINO AND SOUTHERN LINCOLN COUNTIES. THE MAIN THREAT FROM
STORMS OVER THE WEEKEND AND INTO EARLY NEXT WEEK WILL BE HEAVY RAIN
AND THE POTENTIAL FOR FLASH FLOODING.
&&

.UPDATE...AFTER A WILD EVENING OF STRONG WIND AND HEAVY RAIN IN THE
LAS VEGAS VALLEY...STORMS WERE MOVING OFF TO THE SOUTHWEST INTO
NORTHEAST SAN BERNARDINO COUNTY. OVERNIGHT...MOHAVE COUNTY AND
EASTERN SAN BERNARDINO COUNTIES APPEAR TO HAVE THE BEST CHANCE OF
STORMS WHILE ELSEWHERE...INCLUDING LAS VEGAS...SHOULD BE MAINLY DRY.
TWEAKED THE OVERNIGHT POP...SKY AND WEATHER GRIDS TO ACCOUNT FOR THE
LATEST TRENDS.
&&

.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS BETWEEN 10-15 KTS WILL
DECREASE TO AROUND 7-9 KTS OVERNIGHT. SCT-BKN CLOUDS AOA 14K FEET
WILL CONTINUE THROUGH THE EVENING THEN CLEARING. CLOUDS 10-12K FEET
ARE EXPECTED TO INCREASE SATURDAY WITH THUNDERSTORMS POSSIBLE OVER
MAINLY THE LOCAL MOUNTAINS ALTHOUGH THUNDERSTORM OUTFLOW COULD BRING
A STORM INTO THE VALLEY ONCE AGAIN. MORE WIDESPREAD THUNDERSTORMS
ARE EXPECTED IN THE PEACH SPRINGS AND MORMON MESA CORRIDORS SATURDAY
AFTERNOON. THUNDERSTORM CHANCES AT MCCARRAN WILL INCREASE SUNDAY AND
MONDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THUNDERSTORMS WILL MOVE OUT OF NEVADA BY 11 PM AND ONLY
SOUTHERN MOHAVE AND EASTERN SAN BERNARDINO COUNTIES WILL SEE STORM
ACTIVITY CONTINUE BEYOND THEN. SATURDAY WILL BRING SCATTERED
THUNDERSTORM ACTIVITY TO LINCOLN...CLARK...MOHAVE AND SAN BERNARDINO
COUNTIES WITH ISOLATED STORMS POSSIBLE ACROSS THE REMAINDER OF THE
AREA. WINDS WILL GENERALLY BECOME LIGHT TONIGHT THEN EAST TO
SOUTHEAST WITH SPEEDS UP TO 10 KTS SATURDAY AFTERNOON. &&

.PREV DISCUSSION...240 PM PDT FRI JUL 19 2013...

.SHORT TERM...MOISTURE IS ON THE INCREASE WITH DEW POINTS ACROSS THE
AREA UP ABOUT 20-30 DEG OVER SOUTHERN NEVADA AND ABOUT 5-10 IN
MOHAVE COUNTY FROM 24 HOURS AGO. STORMS HAVE STARTED TO FIRE IN
MOHAVE AND LINCOLN COUNTIES EARLY THIS AFTERNOON AND EXPECT MORE
STORMS TO DEVELOP THROUGH THE AFTERNOON. LAPS DATA CONTINUES TO SHOW
INSTABILITY INCREASING OVER MOHAVE COUNTY AND ALSO SPREADING WEST
TOWARD FAR EASTERN SAN BERNARDINO COUNTY AND SOUTHERN LINCOLN
COUNTY. THESE SHOULD BE THE AREAS WITH THE MAIN FOCUS FOR STORMS
INTO THIS EVENING. BY SATURDAY...ADDITIONAL MOISTURE WILL ADVECT
INTO THE REGION AND THIS MOISTURE AND INSTABILITY WILL SPREAD
FURTHER WEST. MODELS SHOW PW VALUES UP TO AN INCH EXTENDING FROM
MUCH OF LINCOLN...CLARK...SOUTHERN INYO AND SAN BERNARDINO COUNTIES
WITH AN INCH AND A HALF PW'S COVERING SOUTHERN MOHAVE...SOUTHERN
CLARK AND EASTERN SAN BERNARDINO COUNTIES. WITH LI VALUES RANGING
FROM -2/-5 AND FAIRLY DECENT CAPE VALUES...DO EXPECT AN UPTICK IN
THUNDERSTORM COVERAGE SATURDAY AFTERNOON. WITH PLENTY OF MOISTURE
AVAILABLE DO EXPECT THESE STORMS TO HAVE THE POTENTIAL TO PRODUCE
FLASH FLOODING. HAVE GONE AHEAD AND ISSUED A FLASH FLOOD WATCH FOR
MOHAVE...THE LAKE MEAD NATIONAL RECREATION AREA...THE COLORADO RIVER
BASIN...AND THE SPRING AND SHEEP RANGES OF SOUTHERN NEVADA.
TEMPERATURES WILL GENERALLY BE A FEW DEGREES ABOVE NORMAL EXCEPT IN
AREAS WHERE CLOUD COVER WILL KEEP READINGS NEAR NORMAL.

.LONG TERM...SUNDAY THROUGH FRIDAY...MODELS CONTINUE TO BE IN GOOD
AGREEMENT DURING THE LONG TERM PERIOD. ON SUNDAY THE BEST MOISTURE
AND INSTABILITY...ALONG WITH THE BEST THUNDERSTORM CHANCES WILL BE
CONFINED PRIMARILY TO THE SOUTHERN HALF OF THE FORECAST AREA.
SOMEWHAT DRIER AIR SHOULD HELP TO SUPPRESS THUNDERSTORM CHANCES IN
THE NORTHERN HALF OF THE AREA ON SUNDAY. THUNDERSTORM CHANCES WILL
INCREASE IN THE NORTHERN HALF OF THE AREA ON MONDAY AS THE UPPER
LEVEL WINDS SHIFT TO A MORE SOUTHERLY DIRECTION...THIS WILL HELP TO
BRING THE MOIST...UNSTABLE AIR NORTHWARD. I SLIGHTLY INCREASED POPS
ON SUNDAY AND MONDAY TO REFLECT THE LATEST MODEL TRENDS.  MOISTURE
DECREASES A LITTLE ON TUESDAY...BUT SUFFICIENT MOISTURE AND
INSTABILITY WILL REMAIN IN PLACE ON TUESDAY FOR THE THREAT OF
THUNDERSTORMS TO CONTINUE. MODELS SHOW A SLIGHT DRYING TREND LATER
IN THE WEEK...THIS WILL HELP TO DECREASE THUNDERSTORM CHANCES
WEDNESDAY THROUGH THE END OF THE PERIOD. I MADE ONLY SIGHT CHANCES
TO THE INHERITED TEMPERATURE GIRDS TO REFLECT THE LATEST
GUIDANCE.
