.SYNOPSIS...ISOLATED TO SCATTERED THUNDERSTORMS WILL BE
POSSIBLE...PRIMARILY OVER THE HIGHER TERRAIN OF INYO
COUNTY...SOUTHERN NEVADA AND NORTHWEST ARIZONA OVER THE WEEKEND.

&&

.UPDATE... LARGE AREA OF MAINLY LIGHT TO MODERATE SHOWERS MOVING
NORTHWEST THROUGH THE SOUTHERN HALF OF THE FORECAST AREA. SO FAR
LIGHTNING HAS BEEN MINIMAL AND CLOUD TOPS HAVE BEEN FAIRLY LOW. LAPS
DATA SHOWS FAIRLY STABLE CONDITIONS ACROSS NORTHERN SAN BERNARDINO
COUNTY INTO INYO COUNTY SO DO NOT EXPECT ANYTHING SIGNIFICANT TO
DEVELOP. MOST OF THIS HAS BEEN IN AREAS WHERE WE HAD LITTLE TO MO
POPS IN THE GRIDS SO MADE A FEW UPDATES TO POPS. WITH THE EXTENSIVE
CLOUD COVER OVER THE SOUTHERN HALF OF THE AREA AND IT LOOKS LIKE IT
COULD REMAIN MUCH OF THE NIGHT WE ARE LOOKING AT ANOTHER FAIRLY WARM
OVERNIGHT LOW. WENT AHEAD AND RAISED LOW TEMPERATURES. UPDATES OUT
SHORTLY.

252 PM PDT FRI JUL 3 2015

.SHORT TERM...SHOWERS AND THUNDERSTORMS HAVE BEEN PRIMARILY LIMITED
WITH A EASTERN HALF OF LINCOLN COUNTY...NORTHERN MOHAVE COUNTY AND
THE MOUNTAINS OF CLARK COUNTY THIS AFTERNOON. DRIER AND MORE STABLE
AIR HAS MADE SIGNIFICANT PROGRESS TO THE EAST OVER THE PAST 24
HOURS. A WEAK SYSTEM WILL MOVE UP FROM ARIZONA ON SATURDAY AND
TEMPORARILY REVERSE THE FLOW TO A MORE SOUTHEASTERLY
FLOW...PROVIDING A SHORT WINDOW ENHANCED MOISTURE AND CHANCES FOR
THUNDERSTORMS ON SATURDAY. THE AREAS MOST LIKELY TO SEE
THUNDERSTORMS ON SATURDAY WILL ONCE AGAIN BE LINCOLN...MOHAVE AND
THE MOUNTAINS OF CLARK COUNTY. AS THE SYSTEM PUSHES INTO NORTHERN
NEVADA AND UTAH SATURDAY NIGHT...SOUTHWESTERLY FLOW WILL BEGIN TO
RETURN...PROVIDING DRIER AIR INTO MUCH OF THE AREA. THIS WILL REDUCE
THUNDERSTORM CHANCES A BIT MORE EACH DAY.

.LONG TERM...BY TUESDAY AFTERNOON A RIDGE OF HIGH PRESSURE WILL BE
CENTERED JUST TO THE EAST OF THE FOUR CORNERS AREA WITH AN UPPER LOW
OFF OF THE NORTHERN CALIFORNIA COAST. THE WILL CONTINUE TO PROVIDE
DRIER SOUTHWEST FLOW ACROSS THE AREA. THERE WILL ONLY BE A SLIGHT
CHANCE OF THUNDERSTORMS ALONG EXTREME NORTHERN AND EASTERN FRINGES
OF OUR FORECAST AREA. BY WEDNESDAY...THE DRIER AIR SHOULD ELIMINATE
THE POTENTIAL OF THUNDERSTORMS ACROSS THE ENTIRE FORECAST AREA. AS
THE LOW MOVES SLOWLY INLAND LATER IN THE WEEK...SOUTHWEST WINDS WILL
INCREASE AND TEMPERATURES WILL DECREASE. TEMPERATURES WILL BE
SEVERAL DEGREES BELOW NORMAL BY MIDWEEK AND LAST INTO THE WEEKEND.
&&

.AVIATION...FOR MCCARRAN...SOUTH TO SOUTHWEST WINDS SHOULD CONTINUE
THROUGH THE EVENING. THUNDERSTORM CHANCES WILL BE QUITE LIMITED
THIS EVENING...WITH THE BEST OPPORTUNITY OVER THE MOUNTAINS. WINDS
WILL DIMINISH OVERNIGHT...BUT THE SOUTHERLY WINDS WILL RETURN ON
SATURDAY AFTERNOON BETWEEN 22 AND 23Z. ISOLATED THUNDERSTORMS WILL
BE POSSIBLE SATURDAY AFTERNOON/EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS THIS AFTERNOON AND
SATURDAY AFTERNOON MAINLY OVER MOHAVE AND LINCOLN 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.
