AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
300 PM PDT SAT AUG 24 2013

.SYNOPSIS...MOISTURE FROM TROPICAL STORM IVO IS EXPECTED TO PUSH
NORTH ACROSS MUCH OF THE AREA TONIGHT THROUGH MONDAY RESULTING
IN A SIGNIFICANT RAIN EVENT OVER PORTIONS OF THE SOUTHERN GREAT
BASIN AND MOJAVE DESERT. THE HIGHEST THREAT OF HEAVY RAIN WILL BE
OVER MOHAVE...CLARK...LINCOLN AND EASTERN SAN BERNARDINO COUNTIES.
MOISTURE IS FORECAST TO REMAIN OVER THE EASTERN HALF OF THE FORECAST
AREA FOR MUCH OF THE WEEK RESULTING IN A CHANCE OF SHOWERS AND
THUNDERSTORMS EACH DAY. TEMPERATURES WILL REMAIN SEVERAL DEGREES
BELOW NORMAL THROUGH MONDAY AND THEN INCREASE TO AROUND NORMAL BY
MID WEEK.
&&

.DISCUSSION...A NICE DRY LINE HAS SET UP STRETCHING FROM SAN
BERNARDINO COUNTY UP THROUGH SOUTHERN NYE INTO NORTHERN LINCOLN
COUNTY WITH SCATTERED THUNDERSTORMS EAST OF THIS LINE AND DRY AND
GUSTY CONDITIONS WEST. STORMS INTO THIS EVENING WILL BE CAPABLE OF
PRODUCING FLASH FLOODING AND POTENTIALLY SEVERE WINDS AND
HAIL...ESPECIALLY OVER SAN BERNARDINO AND LINCOLN COUNTIES. EARLIER
CONVECTION HAS REALLY LIMITED ANY NEW DEVELOPMENT OVER MOHAVE COUNTY
AND NOT MUCH MORE IS EXPECTED THROUGH MIDNIGHT. BIG STORY CONTINUES
TO BE MOISTURE FROM TROPICAL SYSTEM IVO ADVECTING INTO THE AREA
OVERNIGHT AND SUNDAY. MODELS CONTINUE TO BE IN GOOD AGREEMENT WITH
THE SET UP AND HAVE BASICALLY KEPT EVERYTHING THE SAME. ONLY CHANGES
I DID MAKE WERE TO BACK OFF ON THE HIGHER POPS IN THE WEST BETWEEN
THE 12Z-18Z TIME FRAME...BUT ONLY MINOR DROPS. EXCELLENT DYNAMICS
AND PLENTY OF MOISTURE WILL LEAD TO WIDESPREAD RAIN AND EMBEDDED
THUNDERSTORMS THROUGHOUT THE DAY SUNDAY AND INTO MONDAY...MAINLY
OVER THE EASTERN HALF OF THE AREA. OVER THE WESTERN HALF...MOISTURE
WILL NOT BE AS DEEP...BUT THUNDERSTORMS WILL STILL BE POSSIBLE.
GUSTY SOUTHWEST WINDS WILL OCCUR OVER ESMERALDA AND CENTRAL NYE
COUNTIES...BUT THINK THEY WILL REMAIN BELOW ADVISORY LEVELS. MODELS
CONTINUE TO HANG ON TO THE MOISTURE THROUGH MUCH OF THE WEEK SO
SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE EACH
DAY...ESPECIALLY OVER THE EASTERN HALF OF THE FORECAST AREA. THE
ECMWF INDICATES A FAIRLY PRONOUNCED INVERTED TROUGH LIFTING FROM
NORTHWEST MEXICO UP THROUGH SOUTHERN NEVADA THURSDAY WHICH WOULD
BRING CONSIDERABLE MOISTURE WITH IT. THE GFS DOES NOT REALLY
INDICATE THIS YET BUT POPS WERE EXPANDED TO THE NORTHWEST A LITTLE
THURSDAY AND FRIDAY TO MAKE ALLOWANCE FOR THE ECMWF SOLUTION. LITTLE
CHANGE WAS NEEDED TO TEMPERATURES WITH HIGHS REBOUNDING BACK TO
NORMAL BY WEDNESDAY.
&&

.AVIATION...FOR MCCARRAN...ISOLATED SHOWERS AND THUNDERSTORMS
EXPECTED AROUND THE AREA INTO THIS EVENING...BUT CHANCES ARE LOW
THAT THEY WILL MOVE WITHIN 3-5 MILES OF MCCARRAN. SKIES WILL REMAIN
CLOUDY WITH CIGS GENERALLY BETWEEN 12-15K FEET. WINDS ARE FORECAST
TO REMAIN BETWEEN 150-180 DEGREES WITH SPEEDS BETWEEN 10-15 KTS. ITS
STILL POSSIBLE THAT THUNDERSTORM OUTFLOW WILL BRING VARIABLE WINDS
UP TO 30 KTS THROUGH THIS EVENING. SHOWERS AND THUNDERSTORMS ARE
LIKELY ON SUNDAY...WITH PERIODS OF MODERATE TO HEAVY RAIN POSSIBLE
THROUGHOUT THE DAY. CIGS MAY DROP TO AS LOW AS 4-5KFT DURING PERIODS
OF MORE INTENSE PRECIPITATION.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL
CONTINUE INTO THIS EVENING EAST OF A LINE FROM BARSTOW TO BEATTY TO
NORTHERN LINCOLN COUNTY EAST. STORMS ARE CAPABLE OF PRODUCING VERY
HEAVY RAIN...HAIL...AND WIND GUSTS UP TO 50 MPH. WEST OF THAT LINE
SKIES WILL REMAIN CLEAR WITH GUSTY SOUTHWEST WINDS UP TO 35 KTS.
SHOWERS AND THUNDERSTORMS ARE LIKELY ON SUNDAY MAINLY OVER THE
EASTERN HALF OF THE AREA...WITH PERIODS OF MODERATE TO HEAVY RAIN
POSSIBLE THROUGHOUT THE DAY. CIGS MAY DROP TO AS LOW AS 4-5KFT
DURING PERIODS OF MORE INTENSE PRECIPITATION.
