AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
237 PM PDT TUE JUL 5 2011

.SYNOPSIS...MONSOON MOISTURE WILL KEEP CHANCES FOR THUNDERSTORMS
OVER MUCH OF THE MOJAVE DESERT AND SOUTHERN GREAT BASIN THROUGH THE
WEEK. POCKETS OF HEAVY RAIN COULD LEAD TO LOCALIZED FLOODING.
TEMPERATURES WILL BE NEAR TO SLIGHTLY ABOVE NORMAL WHILE HIGHER
HUMIDITY WILL MAKE IT FEEL QUITE UNCOMFORTABLE...ESPECIALLY IN THE
LOWER DESERTS.
&&

.SHORT TERM...ACTIVE THUNDERSTORM DAY WITH THE TWO MAIN AREAS OVER
THE MOUNTAINS BETWEEN MOUNTAIN PASS CALIFORNIA AND MOUNT CHARLESTON
NEVADA...AND OVER THE MORONGO BASIN IN CALIFORNIA. OTHER STORMS WERE
APPROACHING SOUTHERN MOHAVE COUNTY FROM THE EAST AS OF 220 PM...AND
SOME LESS ORGANIZED STORMS WERE RUMBLING OVER NYE AND LINCOLN
COUNTIES. FORECAST REMAINS A DAY BY DAY SITUATION...WITH PLENTY OF
MOISTURE IN PLACE BUT NO LARGE SCALE FORCING. HEATING PLUS SMALL
SCALE LIFTING MECHANISMS SUCH AS OROGRAPHY AND BOUNDARY COLLISIONS
WILL DRIVE STORMS EACH AFTERNOON AND EVENING. VERY LITTLE CHANGE TO
THE PREVIOUS FORECAST SINCE THERE IS NO OBVIOUS FEATURE OF INTEREST
AT LEAST THROUGH TOMORROW EVENING.

.LONG TERM...MONSOONAL FLOW CONTINUES THROUGH THE END OF THE WEEK
WITH MODELS THEN SHOWING SOME DRIER AIR WORKING INTO THE AREA FROM
THE NORTHWEST OVER THE WEEKEND. MOST AREAS WITHIN THE CWA WILL HAVE
A CHANCE OF THUNDERSTORMS THURSDAY AND FRIDAY BUT THEN BECOMING MORE
ISOLATED OVER THE WEST HEADING INTO THE WEEKEND. WHETHER DRIER
CONDITIONS PUSH ENTIRELY THROUGH THE CWA NEXT WEEK AS MODELS ARE
SHOWING IS VERY UNCERTAIN. TO ACCOUNT FOR THE UNCERTAINTY...DID NOT
REMOVE TSTORMS ALTOGETHER BUT LINGERED THEM ACROSS THE EAST IN CASE
THE MOISTURE DOES NOT GET ENTIRELY FLUSHED. TEMPERATURES SHOULD WARM
TO AROUND NORMAL LEVELS EACH DAY BUT WILL BE DEPENDENT ON THE
THICKNESS AND TIMING OF CLOUD COVER. WINDS IN GENERAL ARE EXPECTED
TO BE LIGHT THURSDAY AND FRIDAY BUT COULD BECOME GUSTY FROM THE
SOUTHWEST OVER THE WEEKEND INTO EARLY NEXT WEEK IF A PACIFIC TROUGH
IS ABLE TO PUSH FAR ENOUGH INLAND AND FAR ENOUGH SOUTH.
&&

.AVIATION...FOR MCCARRAN...AWAY FROM ANY THUNDERSTORMS OR
THUNDERSTORM OUTFLOW BOUNDARIES WINDS WILL MAINLY BE SOUTH TO
SOUTH-SOUTHWEST AT 6-12 KTS. CLOUD COVER WILL MAINLY BE SCT AOA 8K
FEET AND BKN AOA 15K FEET THROUGH THIS EVENING. THERE COULD BE SOME
THUNDERSTORMS IN AND AROUND THE LAS VEGAS VALLEY INTO THE EARLY
EVENING WHICH COULD CREATE GUSTY AND ERRATIC WINDS AT TIMES. TSRA
WILL ALSO BE POSSIBLE IN ALL OF THE APPROACH CORRIDORS THROUGH THE
EARLY EVENING. THE THREAT OF TSRA WILL CONTINUE THROUGH AT LEAST
FRIDAY IN AND AROUND THE VALLEY AND AS WELL AS ALL OF THE APPROACH
CORRIDORS. CIGS AND VSBY WILL BE REDUCED IN AND NEAR ANY STORMS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...WINDS IN GENERAL ARE EXPECTED TO BE LIGHT AND FOLLOW
DIURNAL DIRECTIONAL TRENDS. THERE WILL BE A CHANCE OF THUNDERSTORMS
THROUGH MUCH OF THE WEEK WHICH COULD PRODUCE GUSTY...ERRATIC WIND
AND REDUCED VISIBILITY AT TIMES. MAINLY SCT-BKN CLOUDS AOA 7K-10K
FEET WITH LOWER CIGS AND VSBY IN AND NEAR ANY TSRA.
