AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
900 PM PDT SAT JUN 13 2015

.SYNOPSIS...THERE REMAINS A SLIGHT CHANCE OF THUNDERSTORMS OVER THE
HIGHER TERRAIN OF SOUTHEAST NEVADA AND NORTHWEST ARIZONA SUNDAY. A
DRY...WESTERLY FLOW FROM MONDAY ONWARD WILL BRING HOT CONDITIONS TO
THE AREA WITH DAYTIME TEMPERATURES SEVERAL DEGREES ABOVE NORMAL.
&&

.UPDATE...THREW OUT A QUICK UPDATE TO BETTER REFLECT CURRENT STORM
COVERAGE. SOME BETTER ORGANIZED ACTIVITY IS CURRENTLY ONGOING IN
SOUTHWEST LINCOLN COUNTY AND MAY BRUSH EXTREME NORTHEAST CLARK
COUNTY THIS EVENING. INFRARED CLOUD TOPS EXCEED -40C WITH THIS
ACTIVITY AND CONSIDERABLE LIGHTNING ACTIVITY HAS BEEN NOTED.
ADDITIONAL ACTIVITY IS DRIFTING TOWARDS THE LAS VEGAS VALLEY AND MAY
RESULT IN A FEW BRIEF DOWNPOURS AND GUSTY WINDS ESPECIALLY IN THE
NORTH AND WEST SIDES OF THE METRO AREA BUT SOME LIGHT SHOWERS WILL
BE POSSIBLE ALMOST ANYWHERE IN THE VALLEY THROUGH 11PM AS THE
OUTFLOW MOVES THROUGH.

-OUTLER-

.SHORT TERM...THROUGH MONDAY NIGHT.

CONVECTION FIRED EARLY IN THE DAY OVER THE HIGHER TERRAIN OF CLARK
COUNTY BUT SEEMS TO HAVE USED UP ITS AVAILABLE INSTABILITY AS
CONVECTION NEAR THE SPRING MTNS AND SHEEP RANGE HAS WEAKENED GREATLY
OR DISSIPATED ALTOGETHER.

FOR THE REST OF THE AFTERNOON/EARLY EVENING GREATEST INSTABILITY
WILL BE OVER SOUTHERN MOHAVE COUNTY AND EASTERN SAN BERNARDINO
COUNTY, WITHIN THE MOJAVE NATIONAL PRESERVE. SEVERAL OUTFLOW
BOUNDARIES MERGING OVER THE LAKE MEAD NATIONAL RECREATION BUT SO FAR
NEW DEVELOPMENT HAVING A TOUGH TIME PERSISTING. OUTFLOW WINDS FROM
THE EAST COULD AFFECT THE LAS VEGAS VALLEY LATER THIS EVENING. IF
THERE IS A SHIFT SPEEDS DO NOT LOOK THAT IMPRESSIVE, PROBABLY 15 MPH
OR LESS.

ADDITIONAL DRYING AND STABILIZATION OF THE AIR MASS WILL OCCUR
SUNDAY INTO MONDAY. HOWEVER, STILL CAN NOT RULE OUT A FEW
SHOWERS/THUNDERSTORMS OVER THE HIGHER TERRAIN OF SOUTHEAST NEVADA
AND NORTHWEST ARIZONA SUNDAY. MONDAY WILL BE DRY.

AS RIDGE BUILDS IN FROM THE WEST TEMPERATURES WILL BE ON THE RISE
LEADING TO OUR FIRST STRETCH OF CONSECUTIVE 105 DEGREES OR HOTTER
ACROSS THE MOJAVE DESERT.

.LONG TERM...TUESDAY THROUGH FRIDAY.

CONFIDENCE REMAINS HIGH IN THE FIRST PROLONGED PERIOD OF TRIPLE
DIGIT HEAT IN DESERT LOCALES NEXT WEEK AS WESTERLY TO SOUTHWESTERLY
UPPER LEVEL FLOW IS EXPECTED TO DOMINATE THE REGION THROUGH AT LEAST
NEXT WEEKEND. THIS PATTERN WILL AID IN MIXING...BUMPING AFTERNOON
HIGHS UP A FEW DEGREES EACH AFTERNOON...YIELDING THE HOTTEST DAYS OF
2015 SO FAR BY MID-WEEK. AFTERNOON HIGHS WILL RUN ROUGHLY 6-9
DEGREES ABOVE NORMAL FOR MID-JUNE...RANGING FROM 102-109 ACROSS MOST
DESERT LOCATIONS...WITH LOWER DESERT LOCATIONS SUCH AS DEATH
VALLEY...AND THE COLORADO RIVER VALLEY EASILY EXCEEDING 110 AND
PERHAPS 115 AT TIMES THROUGH LATE WEEK. AT THIS TIME...IT APPEARS
THAT MOST RECORDS WILL REMAIN SAFE NEXT WEEK.

THOUGH IT CONTINUES TO LOOK LIKE WE WILL REMAIN JUST BELOW THE
EXCESSIVE HEAT CRITERIA THRESHOLD OF 110 IN LAS VEGAS NEXT
WEEK...INDIVIDUALS AND ORGANIZATIONS HERE AND IN OTHER DESERT
LOCATIONS ARE ENCOURAGED TO PLAN AHEAD BY CHECKING AIR
CONDITIONERS...VEHICLE MAINTENANCE...ETC...AS WELL AS EXERCISING
HEAT SAFETY DURING THIS PROLONGED PERIOD. REMEMBER...HEAT IS THE
LEADING WEATHER RELATED KILLER IN OUR CWA.

&&

.AVIATION...FOR MCCARRAN...OUTFLOW BOUNDARIES TO THE SOUTH AND EAST
OF THE LAS VEGAS VALLEY MAY CONTRIBUTE TO VARYING WIND DIRECTIONS
LATE THIS AFTERNOON AND EVENING. IF THE BOUNDARIES ARE ABLE TO MAKE
INTO THE VALLEY THE DIRECTION WILL FAVOR A SOUTH TO EAST DIRECTION.
SPEEDS WOULD LIKELY REMAIN LESS THAN 10 KTS AS THE BOUNDARIES
WEAKEN. OTHERWISE, EXPECT TYPICAL SOUTHERLY DRAINAGE OVERNIGHT.
PARTLY CLOUDY SKIES WILL BECOME MOSTLY CLEAR OVERNIGHT. WINDS MAY
BRIEFLY GO EASTERLY SUNDAY BEFORE TRANSITIONING SOUTHERLY IN THE
EARLY AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED THUNDERSTORMS GENERALLY IN SOUTHERN MOHAVE AND
SAN BERNARDINO COUNTIES THIS EVENING. THUNDERSTORMS WILL BE CONFINED
MORE TO SOUTHEAST NEVADA AND NORTHWEST ARIZONA SUNDAY. FAIR WEATHER
EXPECTED ELSEWHERE. CONVECTIVE TURBULENCE AND GUSTY SURFACE WINDS
LIKELY NEAR STORM ACTIVITY. GENERALLY LIGHT SOUTH OR SOUTHWESTERLY
WINDS ARE EXPECTED ACROSS THE REGION TODAY IN THE 6-12KT RANGE.
SOUTHWEST WIND SURFACE WINDS INCREASE SUNDAY AFTERNOON WITH GUSTS 20-
30 KTS POSSIBLE.

ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.
