AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
928 PM PST WED NOV 16 2011

.SYNOPSIS...DRY WEST TO NORTHWEST FLOW WILL PERSIST OVER THE AREA
THROUGH THURSDAY WITH VARYING AMOUNTS OF HIGH CLOUDINESS. EXPECT
LIGHT WINDS WITH NEAR NORMAL TEMPERATURES. AN APPROACHING STORM
SYSTEM WILL BRING GUSTY WINDS AREA WIDE FRIDAY AND A CHANCE OF
SHOWERS OVER NORTHERN AND CENTRAL LINCOLN AND NYE COUNTIES FRIDAY
NIGHT. MUCH COOLER TEMPERATURES SATURDAY AND SUNDAY CAN BE EXPECTED
ALONG WITH READINGS ABOUT 10 DEGREES BELOW NORMAL.
&&

.UPDATE...TRANQUIL WEATHER WILL CONTINUE THROUGH THURSDAY AFTERNOON
THEN THE INFLUENCE OF THE BROAD UPPER LOW CURRENTLY ALONG THE
BRITISH COLUMBIA COAST WILL BEGIN TO BE FELT AS IT SLIDES TO THE
SOUTHEAST. WINDS WILL INCREASE ACROSS THE SIERRA THURSDAY NIGHT
THROUGH FRIDAY. THE LATEST LOCAL HIGH RESOLUTION MODELS INDICATE
GOOD POTENTIAL FOR DOWNSLOPE WINDS FOR THE EASTERN SIERRA SLOPES AND
AREAS OF THE OWENS VALLEY FRIDAY MORNING THROUGH FRIDAY EVENING. A
HIGH WIND WATCH LOOKS WARRANTED DURING THIS PERIOD. THE 00Z GFS/NAM
SOLUTIONS KEEP THE BASE OF THE LOW FROM DIGGING TOO FAR INTO THE
SOUTHERN GREAT BASIN AND HAVE NOT CHANGED TOO MUCH FROM THE 12Z/18Z
RUNS. THE REST OF THE FORECAST TRENDS DETAILED BELOW LOOK OKAY.
&&

.PREV DISCUSSION...
315 PM PST WED NOV 16 2011

.SHORT TERM...DRY NORTHWEST FLOW REMAINS OVER THE AREA TODAY AS HIGH
PRESSURE REMAINS SITUATED OFF THE CALIFORNIA COAST. SURFACE HIGH
OVER UTAH PRODUCED ENOUGH GRADIENT TO BRING LOCALLY BREEZY
CONDITIONS DOWN THE COLORADO RIVER TODAY...BUT GRADIENTS ARE
WEAKENING AND WINDS ARE EXPECTED TO BECOME LIGHT BY THIS EVENING.
COLD LOW PRESSURE SYSTEM CURRENTLY OFF THE SOUTHWEST CANADIAN COAST
WILL SLOWLY PUSH SOUTH AND TURN INLAND OVER WA/OR BY FRIDAY MORNING.
THIS WILL TURN THE FLOW MORE SOUTHWESTERLY AND BRING INCREASING
WINDS TO THE AREA. LOOKS LIKE A BELT OF STRONGER WINDS WILL SET UP
ACROSS SAN BERNARDINO...CLARK AND MOHAVE COUNTIES WITH THE STRONGEST
WINDS OVER WESTERN SAN BERNARDINO COUNTY. ALL THE SHORT TERM MODELS
ARE INDICATING THAT THE COLD FRONT THAT WILL PUSH THROUGH NORTHERN
NEVADA FRIDAY EVENING IS EXPECTED TO BE SLOWER AND NOT FORECAST TO
MOVE INTO OUR CWA UNTIL LATE FRIDAY AFTERNOON OR EARLY EVENING. DID
BACK OFF AND REMOVE NEARLY ALL THE POPS BEFORE FRIDAY EVENING. IT
ALSO LOOKS LIKE THE COLD FRONT WILL BE WEAKER AND MAINLY AFFECT
NORTHEAST NEVADA WITH THE BEST CHANCE OF PRECIPITATION...SO AGAIN I
DID LOWER POPS OVER MOST AREAS...EXCEPT NORTHEAST LINCOLN. IT DOES
LOOK LIKE TEMPERATURES WILL COOL SIGNIFICANTLY OVER THE WEEKEND WITH
TEMPERATURES FALLING NEARLY 15 DEGREES FROM FRIDAYS HIGH
TEMPERATURES. ANOTHER SYSTEM DROPPING SOUTH OFF THE NORTHERN
CALIFORNIA COAST SUNDAY AFTERNOON IS EXPECTED TO STAY OFF SHORE AND
KEEP MOISTURE WEST OF THE AREA.

.LONG TERM...THE AREA OF LOW PRESSURE OFF THE SOUTHERN CALIFORNIA
COAST WILL CONTINUE TO DROP SOUTH BEFORE TURNING EAST LATE SUNDAY
AND MONDAY. HAVE REMOVED THE VAST MAJORITY OF PRECIPITATION FROM THE
FORECAST FOR SUNDAY AS THE LOW WILL BE TOO FAR SOUTH AND WEST TO
HAVE MUCH IMPACT ON THE FORECAST AREA. SUNDAY NIGHT AND
MONDAY...THERE IS STILL A SLIGHT CHANCE OF PRECIPITATION ACROSS THE
SOUTHERN EDGE OF THE FORECAST AREA AS THE LOW TRANSITIONS EAST...BUT
IF MODELS KEEP TRENDING WEAKER AND FARTHER SOUTH WITH THE LOW...WILL
HAVE TO ELIMINATE PRECIPITATION COMPLETELY.
SOUTHWESTERLY FLOW WILL RETURN BY TUESDAY IN RESPONSE TO ANOTHER
SHORTWAVE HEADING TOWARDS THE COAST. THIS WILL RESULT IN A MINOR
WARMING TREND.
&&

.AVIATION...FOR MCCARRAN...NO SIGNIFICANT WEATHER IS EXPECTED UNTIL
FRIDAY WITH LIGHT DAYTIME WINDS GENERALLY UNDER 5KTS AND SOUTHWEST
DRAINAGE WINDS AT NIGHT RANGING FROM 6-9KTS. OCCASIONAL CIRRUS WILL
MOVE THROUGH THE AREA THROUGH THURSDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...IN GENERAL...VARIABLE HIGH LEVEL CLOUDINESS IS EXPECTED
THROUGH THURSDAY. WINDS WILL GENERALLY BE LIGHT FOLLOWING LOCAL
DIURNAL PATTERNS THROUGH WEDNESDAY WITH AN INCREASE IN SOUTHERLY
WINDS ACROSS THE NORTH ON THURSDAY.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
NV...NONE.
AZ...NONE.
CA...HIGH WIND WATCH FROM FRIDAY MORNING THROUGH FRIDAY EVENING
     FOR CAZ519-520.
