AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1255 AM PDT SAT JUL 4 2015

.SYNOPSIS...ISOLATED TO SCATTERED THUNDERSTORMS WILL BE
POSSIBLE...PRIMARILY OVER THE HIGHER TERRAIN OF INYO
COUNTY...SOUTHERN NEVADA AND NORTHWEST ARIZONA THIS WEEKEND. A
DRYING TREND IS THEN EXPECTED THROUGH MUCH OF NEXT WEEK ALONG WITH
TEMPERATURES RUNNING A FEW DEGREES BELOW NORMAL.
&&

.SHORT TERM...TODAY THROUGH MONDAY NIGHT.

LIGHT RAIN SHOWERS CONTINUE TO OCCUR OVER THE FAR SOUTHERN HALF OF
THE FORECAST AREA AND ARE EXPECTED TO CONTINUE THROUGH THE EARLY
MORNING HOURS. THESE SHOWERS ARE NOT REALLY PRODUCING MUCH RAINFALL
AND AS THEY CONTINUE TO MOVE NORTHWEST THROUGH CLARK AND SAN
BERNARDINO COUNTIES THEY ARE RUNNING INTO DRIER AND MORE STABLE AIR
AND WEAKENING. THERE WILL STILL BE ENOUGH MOISTURE AND INSTABILITY
IN PLACE TO GENERATE MORE ISOLATED THUNDERSTORMS THIS AFTERNOON OVER
MAINLY THE HIGHER TERRAIN OF MOHAVE AND LINCOLN COUNTIES ALONG WITH
THE SIERRA. WE DO HAVE FAIRLY WIDESPREAD CLOUD COVER OVER MUCH OF
THE CWA THIS MORNING WHICH COULD HAMPER CONVECTIVE DEVELOPMENT THIS
AFTERNOON...BUT THE MODELS DO INDICATE SOME BREAKS IN THE CLOUDS.
THESE CLOUDS COULD ALSO HAVE AN AFFECT ON AFTERNOON HIGH
TEMPERATURES ACROSS THE REGION. SOME MOISTURE AND WEAK INSTABILITY
WILL REMAIN IN PLACE SUNDAY AND MONDAY AFTERNOON FOR A CONTINUED
CHANCE OF ISOLATED AFTERNOON AND EVENING THUNDERSTORMS. WITH LOW
PRESSURE MOVING INLAND DRIER AIR SHOULD KEEP THE STORMS CONFINED TO
MAINLY THE EASTERN HALF OF THE AREA. LAS VEGAS NEEDS ONE MORE DAY OF
105+ TEMPERATURES TO BREAK THE ALL TIME CONSECUTIVE DAYS RECORD OF
21. THIS WILL BE CLOSE. CURRENT FORECAST FOR TODAY IS 105 AND IF WE
SEE SOME SUN THIS AFTERNOON WE SHOULD BREAK THAT RECORD. HOWEVER IF
THE CLOUDS ARE TOO THICK WE MAY FALL JUST SHORT. BEYOND TODAY THE
TEMPERATURES LOOK TO COOL A FEW DEGREES AND BE SLIGHTLY BELOW NORMAL
BY MONDAY.

.LONG TERM...TUESDAY THROUGH SATURDAY.

AN UPPER LOW OFF OF THE NORTHERN CALIFORNIA COAST WILL KEEP A RIDGE
OF HIGH PRESSURE CENTERED WELL TO OUR SOUTHEAST, WITH DRY AND STABLE
SOUTHWEST FLOW ALOFT OVERTAKING THE FORECAST AREA. THERE IS STILL A
SLIGHT CHANCE OF THUNDERSTORMS ALONG EXTREME NORTHERN AND EASTERN
TERRAIN OF OUR FORECAST AREA TUESDAY. HOWEVER, BY WEDNESDAY, THE
DRIER AIR SHOULD ELIMINATE THE POTENTIAL OF THUNDERSTORMS ACROSS THE
ENTIRE FORECAST AREA. THE LOW WILL GRADUALLY SHIFT INLAND LATE IN
THE WEEK. SOUTH-SOUTHWEST WINDS WILL INCREASE ACROSS THE FORECAST
AREA, ESPECIALLY WEDNESDAY THROUGH FRIDAY. AS THE LOW MOVES INLAND,
TEMPERATURES ALOFT WILL SLIGHTLY DECREASE, WHICH WILL CAUSE SURFACE
TEMPS TO TREND COOLER FROM MIDWEEK INTO THE WEEKEND.
&&

.AVIATION...FOR MCCARRAN...SOUTH TO SOUTHWEST WINDS THROUGH 16Z WITH
GENERALLY LIGHT EASTERLY WINDS DURING THE LATE MORNING AND
AFTERNOON. ISOLATED THUNDERSTORMS WILL BE POSSIBLE THIS
AFTERNOON/EVENING. FEW CLOUDS AROUND 15K FEET WITH SKIES REMAINING
BKN AROUND 25K.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS AGAIN THIS
AFTERNOON OVER MAINLY LINCOLN AND MOHAVE COUNTIES ALONG WITH THE
HIGHER TERRAIN OF SOUTHERN NEVADA. WINDS WILL GENERALLY REMAIN BELOW
10KTS...BUT WEST WINDS OVER THE WESTERN PORTIONS OF THE MOJAVE
DESERT WILL BE 15-20 KTS DURING THE LATE AFTERNOON AND EVENING HOURS
THE NEXT COUPLE OF DAYS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTERS ARE ENCOURAGED TO REPORT
ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.
