AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
848 AM PDT THU JUL 4 2013

.SYNOPSIS...AN EXCESSIVE HEAT WARNING WILL CONTINUE THROUGH
INDEPENDENCE DAY FOR THE INTENSE AND DANGEROUS HEATWAVE ACROSS THE
REGION. ISOLATED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
WILL REMAIN POSSIBLE THROUGH SATURDAY BEFORE DRIER CONDITIONS ARRIVE
EARLY NEXT WEEK. GUSTY WINDS AND LIGHTNING WILL BE THE PRIMARY
THREAT WITH THESE STORMS. SLIGHTLY COOLER...BUT STILL ABOVE NORMAL
TEMPERATURES ARE EXPECTED THIS WEEKEND.
&&

.UPDATE...SATELLITE LOOPS SHOWED THE UPPER LEVEL HIGH CIRCULATION WAS
SITUATED JUST EAST OF LAKE MEAD EARLY THIS MORNING WITH A FEW AREAS
OF MID AND HIGH LEVEL CLOUDS...PARTICULARLY ACROSS PARTS MOHAVE
COUNTY. THIS MAY SLOW THE DESTABILIZATION OF THESE AREAS THROUGH THE
MORNING HOURS. A WEAK WAVE CAN BE SEEN NEAR THE BAY AREA OF
CALIFORNIA. THIS IS EXPECTED TO PUSH EAST ACROSS RENO AND ON TO SALT
LAKE CITY BY TOMORROW MORNING. THIS IS A BIT FURTHER NORTH THAN
MODELS INDICATED YESTERDAY...BUT COULD STILL ENHANCE CONVECTION
ACROSS THE FAR NORTHERN AREAS LATE THIS AFTERNOON INTO THIS EVENING.
A POCKET OF INSTABILITY WAS NOTED IN NW SAN BERNARDINO AND SW INYO
COUNTIES THIS MORNING. RAISED POPS JUST ENOUGH TO HAVE A SLIGHT
CHANCE OF SHOWERS/THUNDERSTORMS MENTIONED THIS AFTERNOON.
&&

.AVIATION...FOR MCCARRAN...LIGHT WINDS GENERALLY UNDER 8 KTS FAVORING
AN EASTERLY DIRECTION ARE EXPECTED BY LATE THIS MORNING BEFORE
INCREASING FROM THE SOUTHWEST AROUND 23Z. SCATTERED THUNDERSTORMS ARE
EXPECTED ACROSS THE REGION...AND ALTHOUGH THERE IS ONLY A SLIGHT
CHANCE OF A STORM DIRECTLY IMPACTING KLAS...THERE IS A GOOD CHANCE
OUTFLOW BOUNDARIES FROM STORMS FARTHER AWAY WILL OCCUR AT SOME
POINT...POTENTIALLY DRIVING A CONFIGURATION CHANGE. STRONGER
SOUTHWEST WINDS ARE EXPECTED FRIDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
AGAIN TODAY WITH STORMS CAPABLE OF PRODUCING GUSTY OUTFLOW WIND TO
50 MPH. CLOUDS DECKS WILL MAINLY BE AOA 14K FEET BUT WILL BE LOWER
IN AREAS WHERE SHOWERS AND STORMS DEVELOP. THE GREATEST THUNDERSTORM
COVERAGE IS EXPECTED TO BE NORTH OF LAS VEGAS. STRONGER SOUTHWEST
WINDS ARE EXPECTED FRIDAY.

ISSUED 255 AM PDT THU JUL 4 2013

.SHORT TERM...TODAY THROUGH FRIDAY...THE LARGE AREA OF HIGH PRESSURE
THAT HAS RESULTED IN THE EXTENDED PERIOD OF EXCEPTIONALLY WARM
TEMPERATURES OBSERVED SINCE LAST FRIDAY WILL FINALLY BEGIN TO WEAKEN
AND TRANSITION TO THE SOUTHEAST TODAY AND FRIDAY. HIGH TEMPERATURES
ARE STILL EXPECTED TO MEET OR EXCEED EXCESSIVE HEAT WARNING CRITERIA
TODAY...BUT BY FRIDAY AFTERNOON TEMPERATURES WILL BE SEVERAL DEGREES
COOLER THAN WARNING THRESHOLDS...WITH THE HIGH CENTERED NEAR THE SE
CORNER OF ARIZONA. THUNDERSTORM ACTIVITY TODAY IS EXPECTED TO BE
VERY SIMILAR TO WHAT WAS OBSERVED WEDNESDAY...WITH MINIMAL CHANGE IN
MOISTURE OR INSTABILITY. LATEST MODELS DO NOT INDICATE ANY
SHORTWAVES TO AID IN TRIGGERING OR ORGANIZING ANY THUNDERSTORM
ACTIVITY TODAY...SO EXPECT THUNDERSTORM ACTIVITY TO INITIALLY
DEVELOP OVER HIGHER TERRAIN...AND THEN ANY RESULTING OUTFLOWS TO
DICTATE DEVELOPMENT LATER IN THE DAY. WITH MINIMAL CHANGE TO THE
VERTICAL PROFILE EXPECTED...THE MAIN THREAT ASSOCIATED WITH ANY
STORMS CONTINUES TO BE STRONG WINDS...BRIEF HEAVY RAIN...AND
LIGHTNING. BY FRIDAY...COVERAGE IS EXPECTED TO BECOME MORE SCATTERED
AS DRIER AIR BEGINS TO WORK IN WITH THE HIGH FARTHER SOUTHEAST AND
THE MID LEVEL FLOW OVER THE FORECAST AREA BECOMES MORE SOUTHWESTERLY.

SATURDAY AND SUNDAY...NOT MUCH CHANGE EXPECTED OVER THE WEEKEND AS
HIGH PRESSURE CONTINUES TO LURK JUST TO THE EAST. JUST ENOUGH
MOISTURE WILL REMAIN IN PLACE TO JUSTIFY SLIGHT CHANCE TO LOW END
CHANCE POPS MAINLY OVER THE HIGHER TERRAIN OF THE NORTHERN AND
EASTERN ZONES. TEMPERATURES WILL COME DOWN A LITTLE MORE...BUT STILL
REMAIN ABOVE NORMAL.

.LONG TERM...MONDAY THROUGH WEDNESDAY...A DRYING TREND IS EXPECTED
TO GET UNDERWAY ON MONDAY AS A SHORTWAVE TROUGH MOVES ALONG THE
U.S./CANADIAN BORDER AND TURNS THE FLOW FROM SOUTHERLY TO WESTERLY
OVER OUR AREA. KEPT SLIGHT CHANCE POPS OVER EASTERN LINCOLN AND
MOHAVE COUNTIES TO ACCOUNT FOR UNCERTAINTY IN THE EXTENT OF THE
DRYING...BUT IF THE OPERATIONAL MODELS ARE RIGHT...EVEN THESE SMALL
POPS COULD BE OVERDONE. MOISTURE COULD GET PULLED BACK INTO MOHAVE
COUNTY BY THURSDAY AS A TROUGH OF LOW PRESSURE APPROACHES THE
CALIFORNIA COAST. TEMPERATURES WILL RISE A COUPLE OF DEGREES IN
RESPONSE TO THE DRYING...REMAINING ABOVE NORMAL BUT BELOW EXCESSIVE
HEAT WARNING LEVELS.

SCATTERED AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED TODAY
WITH DRY LIGHTNING AND GUSTY WINDS THE PRIMARY CONCERN. THE AREAL
EXTENT OF THE DRY LIGHTNING...HOWEVER...IS NOT ENOUGH TO WARRANT ANY
ADDITIONAL FIRE WEATHER PRODUCTS. A WEAK TROUGH MOVING INTO THE

INTO THE WEEKEND BRINGING SLIGHTLY COOLER TEMPERATURES TO THE AREA.
THE DIURNAL CYCLE OF THUNDERSTORMS COULD BRIEFLY DRAW TO A CLOSE
EARLY NEXT WEEK AS DRY AND STABLE CONDITIONS ARE FORECAST.
