AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
740 PM PDT MON AUG 31 2015

.SYNOPSIS...DRY SOUTHWESTERLY FLOW WILL CONTINUE TO BRING DRY
WEATHER WITH BREEZY AFTERNOONS AND SEASONABLE TEMPERATURES THROUGH
THE WEEK. A FEW ISOLATED THUNDERSTORMS WILL REMAIN POSSIBLE THROUGH
TUESDAY AFTERNOON ACROSS THE MOUNTAINS OF MOHAVE COUNTY WITH JUST
PASSING HIGH CLOUDS EXPECTED ELSEWHERE.
&&

.UPDATE...ONLY VERY SLIGHT ADJUSTMENTS TO THE GRIDS THIS EVENING.
WITH THE EXCEPTION OF A FEW LIGHT SHOWERS NEAR COLORADO
CITY...SHOWERS ACROSS MOHAVE COUNTY HAVE EXITED THE REGION WITH
CLEARING SKIES EXPECTED THROUGH MIDNIGHT. THE FORECAST IS IN GOOD
SHAPE AND NO SIGNIFICANT UPDATES ARE PLANNED.

-OUTLER-

&&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY.

JUST A COUPLE ISOLATED SHOWERS SO FAR THIS AFTERNOON WITH NO
LIGHTNING DETECTED IN MOHAVE COUNTY AS OF 21Z. BROAD SOUTHWEST FLOW
HAS BROUGHT DRY CONDITIONS ACROSS THE REMAINDER OF THE SOUTHERN
NEVADA AND SOUTHEAST ARIZONA. NO SIGNIFICANT CHANGES WERE MADE TO
THE FORECAST THIS AFTERNOON...WITH CONDITIONS EXPECTED TO CHANGE
VERY LITTLE THE NEXT COUPLE DAYS. EXPECT DRY CONDITIONS...WITH
BREEZY AFTERNOONS AND AN EVERY SO SLIGHT (10-25 PERCENT) CHANCE OF
SHOWERS/TS OVER FAR NORTHEASTERN MOHAVE COUNTY THROUGH WEDNESDAY.
THE ONLY OTHER CONCERN CONTINUES TO BE SMOKE ACROSS THE NORTHWESTERN
FORECAST AREA FROM THE ROUGH FIRE ALONG THE WESTERN SLOPES OF THE
SIERRA.

.LONG TERM...THURSDAY THROUGH SUNDAY.

A PACIFIC STORM SYSTEM IS FORECAST TO DEEPEN AND MOVE ACROSS THE
PACIFIC NORTHWEST INTO THE NORTHERN ROCKIES DURING THIS TIME FRAME.
THIS SHOULD KEEP OUR FORECAST AREA UNDER A DRY SOUTHWEST FLOW WITH
TEMPERATURES NEAR OR JUST SLIGHTLY BELOW NORMAL. BREEZY TO WINDY
SOUTH TO SOUTHWEST WINDS ARE EXPECTED THURSDAY AND FRIDAY BUT SHOULD
DECREASE SOME OVER THE WEEKEND AS THE STORM MOVES INTO THE NORTHERN
ROCKIES. THE MODELS CONTINUE TO SHOW A TROPICAL SYSTEM JUST WEST OF
THE TIP OF BAJA THURSDAY MORNING AND GETTING PICKED UP BY THE
SOUTHWEST FLOW. IT LOOKS LIKE THE BULK OF THE ASSOCIATED MOISTURE
WILL TRACK JUST EAST OF OUR FORECAST AREA BUT COULD JUST CLIP MOHAVE
COUNTY. I DID NOT HAVE ENOUGH CONFIDENCE TO ADD ANY THUNDERSTORMS
CHANCES THERE YET BUT THAT CANNOT BE RULED OUT COMPLETELY FOR THE
FRIDAY/SATURDAY TIME FRAME PERHAPS.
&&

.AVIATION...FOR MCCARRAN...FAIR WEATHER EXPECTED WITH JUST SOME
PASSING HIGH CLOUDS EXPECTED NEAR THE TERMINAL. SOUTHEAST WINDS WILL
TRANSITION TO A SOUTHWEST WIND BETWEEN 21Z AND 23Z TODAY...WITH
GUSTS TO NEAR 20 KTS. WINDS WILL DECREASE OVERNIGHT. ISOLATED
THUNDERSTORMS AGAIN POSSIBLE NEAR THE PEACH SPRINGS CORRIDOR AND
WILL DISSIPATE EARLY IN THE EVENING. SIMILAR CONDITIONS EXPECTED
TUESDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...FAIR WEATHER IS EXPECTED ACROSS MOST OF THE REGION WITH
ONLY ISOLATED THUNDERSTORMS IN NORTHWEST ARIZONA TODAY AND TUESDAY.
SOUTHERLY WINDS MAY BECOME BREEZY AT TIMES IN THE AFTERNOONS WITH
GUSTS OF 20-25KTS. AREAS OF SMOKE CAN AGAIN BE EXPECTED IN THE OWENS
VALLEY AND NEAR KBIH.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER ACTIVATION WILL NOT BE
NECESSARY. HOWEVER...SPOTTERS ARE ENCOURAGED TO REPORT ANY
SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.
