...ELEVATED POTENTIAL FOR FLASH FLOODING ACROSS THE SOUTHERN GREAT
BASIN AND MOJAVE DESERT TODAY...

.SCATTERED TO NUMEROUS THUNDERSTORMS PRODUCING HEAVY RAINFALL CAN BE
EXPECTED ACROSS THE SOUTHERN GREAT BASIN AND MOJAVE DESERT THROUGH
THIS EVENING LEADING TO AN ELEVATED THREAT OF EXTENSIVE FLASH FLOODING.
THIS IS DUE TO A LARGE UPPER LEVEL DISTURBANCE LIFTING FROM SOUTHERN
CALIFORNIA INTO SOUTHERN NEVADA COMBINED WITH A VERY MOIST AND
UNSTABLE AIR MASS IN PLACE.

THE FLASH FLOOD WATCH CONTINUES FOR

* PORTIONS OF NORTHWEST ARIZONA...CALIFORNIA AND NEVADA... INCLUDING
  THE FOLLOWING AREAS...IN NORTHWEST ARIZONA...LAKE HAVASU AND FORT
  MOHAVE...LAKE MEAD NATIONAL RECREATION AREA... NORTHWEST DESERTS
  AND NORTHWEST PLATEAU. IN CALIFORNIA...CADIZ BASIN...DEATH VALLEY

  COUNTY...LAKE MEAD NATIONAL RECREATION AREA...LAS VEGAS
  VALLEY...LINCOLN COUNTY... NORTHEAST CLARK COUNTY...SHEEP
  RANGE...SOUTHERN CLARK COUNTY...SPRING MOUNTAINS-RED ROCK CANYON
  AND WESTERN CLARK AND SOUTHERN NYE COUNTY.

* THROUGH 9 PM THIS EVENING

* A LARGE UPPER LEVEL DISTURBANCE COULD POTENTIALLY ORGANIZE STRONG
  THUNDERSTORMS WITH HEAVY RAINFALL THROUGH THIS EVENING. WITH
  PLENTY OF MOISTURE IN PLACE ACROSS THE SOUTHERN GREAT BASIN AND
  MOJAVE DESERT...THUNDERSTORMS COULD EASILY PRODUCE ONE TO TWO
  INCHES OF RAINFALL IN A SHORT PERIOD OF TIME. AREAS NEAR RECENT
  BURN SCARS WILL ALSO BE MORE SUSCEPTIBLE TO INCREASED RUNOFF AND
  FLASH FLOODING OR DEBRIS FLOWS.

* MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR 
  VEHICLE INTO AREAS WHERE THE WATER COVERS THE ROADWAY SINCE 
  FLOOD WATERS ARE USUALLY DEEPER THAN THEY APPEAR. JUST ONE 
  FOOT OF FLOWING WATER IS POWERFUL ENOUGH TO SWEEP VEHICLES OFF 
  THE ROAD. WHEN ENCOUNTERING FLOODED ROADS MAKE THE SMART 
  CHOICE...TURN AROUND...DONT DROWN. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...A FLASH FLOOD WATCH MEANS THAT
CONDITIONS MAY DEVELOP THAT LEAD TO FLASH FLOODING. FLASH FLOODING
IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR FORECASTS AND BE PREPARED TO TAKE ACTION SHOULD
FLASH FLOOD WARNINGS BE ISSUED FOR YOUR AREA.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
946 PM PDT SUN JUL 27 2014

.SYNOPSIS...MONSOON MOISTURE WILL BRING A CHANCE OF THUNDERSTORMS TO
MUCH OF THE AREA THROUGH THE FIRST HALF OF THE WEEK. TEMPERATURES
WILL GENERALLY BE NEAR NORMAL.
&&

.UPDATE...
A BIT MORE ACTIVE THIS EVENING WHEN COMPARED TO YESTERDAY. WE HAD
SOME LOCALIZED FLOODING ACROSS THE AREA AND EVEN A DUST STORM FROM
DOLAN SPRINGS TO KINGMAN AZ ALONG HIGHWAY 93. MCCARRAN AIRPORT
MEASURED 0.01 INCHES OF RAIN SO I GUESS WE CAN START A NEW DRY
STREAK. A MESOSCALE CONVECTIVE VORTEX CONTINUES TO SLOWLY TRACK
ACROSS SAN BERNARDINO COUNTY AT THIS HOUR. EXPECT SHOWERS AND SOME
THUNDERSTORMS TO CONTINUE ACROSS OUR WESTERN FORECAST AREA FOR MUCH
OF THE OVERNIGHT HOURS WITH THAT FEATURE HANGING AROUND. WE MAY SEE
A LULL AT SOME POINT...BUT HIRES MODELS INDICATE ACTIVITY TO PICK UP
ACROSS OUR WEST IN THE PRE-DAWN HOURS. WE CONTINUE TO WATCH A
WEAKENING STORM COMPLEX EDGE INTO MOHAVE COUNTY FROM NORTHERN AZ.
THIS WILL LIKELY BRING SOME SHOWERS AND PERHAPS A FEW RUMBLES OF
THUNDER TO PORTIONS OF MOHAVE COUNTY TONIGHT. ADDITIONALLY...THERE
IS A PV ANOMALY WORKING NORTHWARD FROM BAJA. THIS WILL BE OUR MAIN
PLAYER FOR TOMORROW BUT WILL ALSO KEEP LARGE-SCALE FORCING AROUND
THE REGION FOR A CONTINUATION OF SOME CONVECTION OVERNIGHT.
&&

.AVIATION...FOR MCCARRAN...THUNDERSTORMS NEAR THE TERMINAL WILL
BRING ERRATIC GUSTY WINDS AT TIMES MONDAY EVENING. ISOLATED TO
SCATTERED THUNDERSTORMS ARE EXPECTED IN ALL FOUR CORRIDORS AS WELL.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED
AREAWIDE MONDAY. EXPECT ERRATIC GUSTY WINDS...VERY HEAVY RAIN AND
LOW CEILINGS IN AND NEAR THUNDERSTORMS.
&&

.PREVIOUS DISCUSSION...
242 PM PDT SUN JUL 27 2014

.SHORT TERM...THROUGH TUESDAY NIGHT...WILL BE BRIEF AS THUNDERSTORMS
ARE FIRING NORTH OF A LINE FROM MOUNTAIN PASS CA TO THE WEST RIM OF
THE GRAND CANYON AS OF 2 PM. HIGH RESOLUTION MODELS HAVE BEEN DOING
QUITE WELL WITH THUNDERSTORM COVERAGE THE PAST FEW DAYS...AND THEY
SUGGEST MORE COVERAGE FOR TOMORROW. LOTS OF MOISTURE IN PLACE SO THE
MAIN THREAT WILL CONTINUE TO BE FLASH FLOODING. MADE NO CHANGES TO
TUESDAY AS THIS EVENING AND TOMORROW WERE THE MAIN CONCERNS.

.LONG TERM...WEDNESDAY THROUGH SUNDAY...AN UPPER LEVEL HIGH PRESSURE
RIDGE WILL REMAIN ANCHORED IN PLACE OVER THE SW US FOR MOST OF THE
PERIOD. THIS WILL KEEP THE AREA RELATIVELY MOIST AND ACTIVE WITH
AFTERNOON CONVECTION FOR MOST OF THE WEEK. ALTHOUGH MONDAY IS LIKELY
TO BE THE MOST ACTIVE DAY. POPS AND CHANCES FOR THUNDERSTORMS WILL
BE SOMEWHAT LOWER THROUGH THE WEEK AS THE SOUTHERLY FLOW IS SOMEWHAT
WEAKER. AFTERNOON SHOWER AND THUNDERSTORMS WILL BE MOST LIKELY TO
OCCUR OVER MOHAVE COUNTY AND HIGHER TERRAIN IN CLARK AND EASTERN SAN
BERNARDINO COUNTY.

AN AFOREMENTIONED UPPER LEVEL TROF WILL SINK SOUTH OVER THE PACIFIC
COAST NEXT WEEKEND. THIS MAY BRING ABOUT SOME STRONGER MID-LEVEL
FORCING FOR CONVECTIVE ACTIVITY. WE WILL NEED TO SEE HOW THINGS
DEVELOP OVER THE COURSE OF THE WEEK.
&&

.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.
