AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
930 AM PDT TUE OCT 9 2007

.SYNOPSIS...HIGH PRESSURE OVER THE AREA WILL ALLOW FOR THE WARMING
TREND TO CONTINUE TODAY. A PACIFIC NORTHWEST STORM WILL PUSH ACROSS
THE SOUTHERN SIERRA LATE TONIGHT AND INTO NORTHERN NEVADA ON
WEDNESDAY...BRINGING THE POSSIBILITY OF WARNING LEVEL WINDS ACROSS
INYO COUNTY ZONES...AND LOCALLY BREEZY BUT CONTINUED DRY CONDITIONS
ELSEWHERE.
&&

.UPDATE...BASED ON 12Z MODELS SO FAR...INHERITED PACKAGE LOOKS GOOD.
NO UPDATE WILL BE MADE THIS MORNING. HIGH WINDS ARE STILL EXPECTED
ACROSS INYO COUNTY ZONES LATE TONIGHT AND TOMORROW MORNING...AND THE
WATCH WILL BE REPLACED BY EITHER A WARNING OR ADVISORY WITH THE
AFTERNOON PACKAGE.

&&
.AVIATION...FOR MCCARRAN...MAINLY CLEAR SKIES TODAY. EAST TO
SOUTHEAST WINDS UNDER 10 KTS INTO EARLY AFTERNOON WILL BECOME SOUTH
AROUND 10 KNOTS BY MID AFTERNOON. SOUTHWEST WINDS UNDER 10 KNOTS ARE
EXPECTED TONIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY CLEAR SKIES WITH LIGHT WINDS THROUGH THE
MORNING. SOUTHERLY WINDS WILL DEVELOP IN THE AFTERNOON WITH HEATING
AND GUSTS BETWEEN 20 AND 25 KNOTS ARE EXPECTED AT BIH AND DRA.

&&
.PREV DISCUSSION FROM 930 AM PDT TUE OCT 9 2007...A WEAK CIRCULATION
AS SEEN ON WATER VAPOR OVER NORTHERN BAJA CAUSING SOME HIGH LEVEL
MOISTURE TO DRIFT NORTHEAST IN SOUTHWEST FLOW ALOFT...BUT OVERALL
EXPECTED SUNNY SKIES ACROSS THE CWA TODAY. NEXT SHORT WAVE TROUGH
WITH CENTER CURRENTLY NEAR 44N/134W TO SHIFT INTO NORTHWEST NEVADA
OVERNIGHT WITH INCREASED SOUTHWEST GRADIENTS INTO THE SOUTHERN
SIERRA BY 12Z WED. MAIN CONCERN FROM THIS SYSTEM WILL BE THE
POSSIBILITY OF STRONG WINDS OVER THE SOUTHERN SIERRA CREST AND
DOWNSLOPE WINDS INTO THE OWENS VALLEY. WILL CONTINUE WITH THE HIGH
WIND WATCH FOR LATE TONIGHT INTO WEDNESDAY FOR THIS AREA. REMAINDER
OF THE CWA WILL SEE LOCALLY BREEZY CONDITIONS ON WEDNESDAY AS TROUGH
SHIFTS ACROSS THE NORTHERN PORTION OF THE CWA...BUT LITTLE ELSE AS
MAIN ENERGY REMAINS WELL NORTH OF THE AREA. BY LATE WEDNESDAY INTO
THURSDAY SOUTHWEST FLOW ALOFT RETURNS AND REMAINS ACROSS THE AREA
INTO THE LONG TERM. EVEN WITH THE TROUGH PASSING TO THE NORTH ON
WEDNESDAY...LITTLE CHANGE EXPECTED IN HEIGHTS/THICKNESS. THUS
TEMPERATURES TO RISE A FEW MORE DEGREES TODAY AHEAD OF THE SYSTEM
AND THEN BE FAIRLY CONSTANT BOTH WEDNESDAY AND THURSDAY...WITH MOST
READINGS BEING NEAR NORMAL.

.LONG TERM...ACTIVE PATTERN CONTINUES TO BE IN THE CARDS FOR OUR
AREA FROM SATURDAY INTO THE MIDDLE OF NEXT WEEK. MODELS REMAIN IN
GOOD AGREEMENT THAT A SYSTEM CURRENTLY SOUTH OF THE ALEUTIANS WILL
MOVE INTO THE ROCKIES STARTING FRIDAY AS AN ASSOCIATED TROUGH SWINGS
INTO NEVADA. SHOWERS ARE STILL EXPECTED TO BE CONFINED TO FAR
NORTHERN PORTIONS OF THE CWA SO WIND WILL REMAIN THE BIG IMPACT FOR
THE AREA. THINKING IS THAT THE POSITION OF THE TROUGH WILL BRING THE
BEST WINDS TO THE SOUTHERN THIRD OF THE CWA WHERE A JET MAX OF
AROUND 100 KTS WILL BE LOCATED. THERMAL GRADIENT AT 700 MB
STILL REMAINS AROUND 10 DEGREES BETWEEN KLAS AND MEDFORD ON THE
EUROPEAN WHICH WOULD GIVE US THE POTENTIAL FOR GUSTS TO AROUND 30KTS
AT KLAS. TEMPERATURES BY SATURDAY WILL COOL AROUND 10 DEGREES FROM
HIGHS ON THURSDAY AS THE TROUGH PASSES AND SWITCH OVER TO THE
NORTHWEST. MEN AND MEX NUMBERS STILL SEEM TOO WARM FOR HIGHS SO WENT
WITH VALUES BELOW GUIDANCE. CONDITIONS WILL IMPROVE ON SUNDAY AS A
WEAK RIDGE BUILDS IN BEFORE THE NEXT SYSTEM CRASHES INTO CALIFORNIA
ON MONDAY. THIS ONE BEARS WATCHING AS THE EUROPEAN BRINGS A FAIR
AMOUNT OF MOISTURE WITH IT TO THE ENTIRE CWA. DID GO WITH AT LEAST
10 POPS OUT ON DAY 8 TO REFLECT THE POTENTIAL AND WENT WITH 20 POPS
FOR FAR WESTERN LOCATIONS.
