AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
140 AM PDT SAT AUG 29 2015

.SYNOPSIS...MOSTLY DRY AND BREEZY CONDITIONS ARE EXPECTED INTO EARLY
NEXT WEEK WITH ANY THUNDERSTORM ACTIVITY CONFINED TO EASTERN MOHAVE
COUNTY SATURDAY AND SUNDAY AFTERNOON. TEMPERATURES WILL REMAIN
SEVERAL DEGREES ABOVE NORMAL SATURDAY THEN BECOME MORE SEASONAL
SUNDAY AND MONDAY. DRY CONDITIONS ALONG WITH BREEZY AND COOLER
CONDITIONS ARE EXPECTED THROUGH THE UPCOMING LABOR DAY WEEKEND.
&&

.SHORT TERM...THROUGH MONDAY NIGHT...

TROUGH PUSHING INTO THE WEST COAST WILL BRING DRIER AND MORE STABLE
CONDITIONS TO MUCH OF THE FORECAST AREA TODAY. FORECASTED SOUNDINGS
STILL SHOWING SOME MOISTURE REMAINING IN THE MID LEVELS SO WE SHOULD
STILL SEE A FEW CUMULUS CLOUDS THIS AFTERNOON...BUT THE SOUNDINGS
ARE ALSO SHOWING A WARMING LAYER JUST ABOVE THIS MOISTURE SO
ANYTHING THAT DOES DEVELOP SHOULD REMAIN CAPPED AND THUNDERSTORMS
ARE NOT EXPECTED OUTSIDE OF EASTERN MOHAVE COUNTY WHERE SOME SLIGHT
INSTABILITY REMAINS. WITH THE APPROACH OF THE TROUGH THE SOUTHWEST
FLOW WILL INCREASE THIS AFTERNOON BRINGING BREEZY CONDITIONS TO MUCH
OF THE AREA WITH WINDY CONDITIONS OVER PORTIONS OF ESMERALDA AND
CENTRAL NYE COUNTIES. WINDS ARE EXPECTED TO REMAIN BELOW ANY
ADVISORY LEVELS. TEMPERATURES TODAY ARE EXPECTED TO TOP OUT AS THE
WARMEST OF THE WEEK WITH READINGS GENERALLY ABOUT 6-8 DEGREES ABOVE
NORMAL. EXCESSIVE HEAT CRITERIA IS CURRENTLY AT 108 DEGREES AND FEEL
THAT LAS VEGAS WILL FLIRT WITH THAT NUMBER...ESPECIALLY WITH THE
GOOD MIXING EXPECTED. HOWEVER...SINCE ITS BORDERLINE ELECTED NOT TO
ISSUE ANY EXCESSIVE HEAT PRODUCTS.

SLIGHT COOLING WILL TAKE PLACE SUNDAY AS THE TROUGH MOVES CLOSER TO
THE REGION AND HEIGHTS LOWER. WINDS WILL STILL REMAIN GUSTY OVER THE
EASTERN HALF OF THE AREA WITH BREEZY CONDITIONS EXPECTED. WINDS WILL
BE A BIT LIGHTER ACROSS THE WESTERN HALF OF THE AREA. WE WILL
PROBABLY SEE A FEW CLOUDS OVER EASTERN MOHAVE COUNTY...BUT
THUNDERSTORMS SHOULD REMAIN EAST OF THE AREA. BY MONDAY THERE SHOULD
BE ENOUGH DRY AIR WITH THE SOUTHWEST FLOW THAT ANY LOW LEVEL
MOISTURE WILL BE PUSHED EAST OF THE AREA. TEMPERATURES WILL ALSO
COOL A FEW MORE DEGREES MONDAY AND TOP OUT VERY CLOSE TO NORMAL FOR
THIS TIME OF YEAR.

.LONG TERM...TUESDAY THROUGH SATURDAY.

HAS THE 2015 MONSOON SEASON COME TO AN END? AT LEAST THROUGH THE
UPCOMING LABOR DAY HOLIDAY WEEKEND IT LOOKS SO. MONSOON MOISTURE
WILL BE SUPPRESS WELL TO OUR SOUTHEAST THANKS TO BROAD TROUGH
ENCOMPASSING THE GULF OF ALASKA, PAC NW AND WRN CANADA TUESDAY. THE
TROUGH IS FORECAST TO AMPLIFY OVER THE WESTERN STATES BY WEEKS END
AS ENERGY DIGS THROUGH THE NORTHERN GREAT BASIN. REGION WILL REMAIN
DRY THROUGH THE PERIOD WITH BREEZY TO LOCALLY WINDY
AFTERNOON/EVENING HOURS. THE ENTIRE PERIOD LOOKS TO HAVE HIGH
TEMPERATURES BETWEEN 3 TO 5 DEGREES BELOW NORMAL. THE DRIER AIR WILL
ALSO ALLOW FOR MORE COMFORTABLE OVERNIGHT LOWS AS WELL.
&&

.AVIATION...FOR MCCARRAN...DIURNAL SOUTHWEST WINDS THROUGH EARLY
MORNING THEN SOUTHWEST WINDS WILL INCREASE BY AFTERNOON WITH SPEEDS
BETWEEN 12-22KTS. FEW CLOUDS 10-12K FEET WITH SCT CLOUDS A0A 20K
FEET THIS AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...FEW CLOUDS WILL DEVELOP THIS AFTERNOON WITH ONLY THE
FAR EASTERN PORTIONS OF MOHAVE COUNTY SEEING ANY THUNDERSTORM
CHANCES. SOUTHWEST WINDS WILL INCREASE THIS AFTERNOON WITH SPEEDS
BETWEEN 12-22KTS.
