AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
200 AM PDT MON AUG 31 2015

.SYNOPSIS...DRY SOUTHWESTERLY FLOW WILL CONTINUE TO BRING DRY
WEATHER WITH 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. &&

.SHORT TERM...TONIGHT THROUGH WEDNESDAY.

CONDITIONS TODAY WILL CLOSELY RESEMBLE WHAT WE OBSERVED SUNDAY WITH
ISOLATED CONVECTION AGAIN PROBABLE ACROSS PARTS OF MOHAVE COUNTY.
HIGH CLOUD COVERAGE SHOULD BE A BIT LESS THAN OBSERVED SUNDAY BUT
PERIODS OF HIGH CLOUD COVER WILL CONTINUE TO BE POSSIBLE.
OTHERWISE...TEMPERATURES ACROSS THE REGION WILL HOVER WITHIN A FEW
DEGREES OF WHAT IS TYPICAL FOR THE END OF AUGUST.

ON TUESDAY...SOUTHWESTERLY FLOW REMAINS IN PLACE WITH THE BULK OF
MOISTURE AND INSTABILITY WHICH AS FUELED ISOLATED THUNDERSTORMS THE
PAST COUPLE DAYS FINALLY SHIFTING EASTWARD. SOME ISOLATED STORMS
WILL REMAIN POSSIBLE NEAR MT. TRUMBULL BUT OVERALL COVERAGE SHOULD
BE VERY SPARSE.  BY WEDNESDAY...DRY CONDITIONS UNDER A STRENGTHENING
SOUTHWESTERLY FLOW CAN BE EXPECTED AREAWIDE WITH TEMPERATURES
HOVERING TO NEAR NORMAL SEASONAL VALUES.

.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. A LIGHT EAST-
SOUTHEAST WIND COMPONENT MAY DEVELOP BY MID-MORNING THEN TRANSITION
TO SOUTH WITH GUSTS AROUND 20 KNOTS THIS AFTERNOON. ISOLATED
THUNDERSTORMS AGAIN POSSIBLE NEAR THE PEACH SPRINGS CORRIDOR AND
WILL DISSIPATE EARLY IN THE EVENING.

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 THIS AFTERNOON.
SOUTHERLY WINDS MAY BECOME BREEZY AT TIMES IN THE AFTERNOON 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.
