AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
300 AM PST WED NOV 11 2009
.SYNOPSIS...TWO STORM SYSTEMS WILL AFFECT THE REGION THROUGH THE
WEEKEND. THE FIRST WILL BRING A CHANCE FOR STRONG DOWNSLOPE WINDS ON
THE EASTERN SLOPES OF THE SIERRA AND SPRING MOUNTAINS TONIGHT AND
THURSDAY...FOLLOWED BY COOLER TEMPERATURES AND CHANCES FOR RAIN AND
MOUNTAIN SNOW MAINLY IN THE SOUTHERN GREAT BASIN THURSDAY INTO
FRIDAY MORNING. THE SECOND STORM WILL BRING GUSTY NORTH TO NORTHWEST
WINDS AND ADDITIONAL COOL AIR OVER THE WEEKEND. QUIET WEATHER IS
EXPECTED FOR THE FIRST HALF OF NEXT WEEK WITH TEMPERATURES WARMING
BACK TO NEAR NORMAL.
&&
.SHORT TERM...LOTS OF ISSUES THIS MORNING SO WILL HIT THE HIGH
POINTS. HIGH RESOLUTION ARW MODEL SHOWS GOOD DOWNSLOPE WIND
POTENTIAL ON THE EAST SLOPES OF THE SIERRA AND SPRING MOUNTAINS
TONIGHT INTO THURSDAY...SO HOISTED HIGH WIND WATCHES FOR THESE
AREAS. INCLUDED THE OWENS VALLEY DUE TO POTENTIAL FOR HIGH WINDS
SPILLING DOWN TO THE VALLEY FLOOR. THE WEST SIDE OF THE LAS VEGAS
VALLEY COULD SEE SOME STRONG WINDS AS WELL...BUT CHOSE NOT TO
INCLUDE THAT AREA IN THE WATCH DUE TO ISOLATED NATURE OF THREAT. NEW
MODELS HAVE REDUCED THE PRECIP THREAT THURSDAY AND THURSDAY NIGHT
QUITE A BIT...WITH MUCH LESS SOUTHWARD PENETRATION THAN SHOWN IN
EARLIER RUNS. TRIMMED BACK POPS TO REFLECT A COMPROMISE BETWEEN THE
PREVIOUS FORECAST AND THE NEW RUNS. PRECIP THREAT SHOULD END FRIDAY
MORNING...THEN AS THE SHORT TERM ENDS FRIDAY NIGHT...ANOTHER STORM
SYSTEM WILL BE DIGGING THROUGH THE NORTHERN ROCKIES. THE ASSOCIATED
COLD FRONT COULD ALREADY BE INTO OUR NORTHERN ZONES BY EARLY
SATURDAY MORNING.
.LONG TERM...SATURDAY MORNING THROUGH TUESDAY...ANOTHER FRONT WILL
MOVE TROUGH THE AREA SATURDAY TO KEEP TEMPERATURES BELOW NORMAL FOR
THE WEEKEND. WENT WITH A BLEND OF GFS AND EC AS GFS IS STARTING TO
GET IN SYNC WITH THE EC AND ITS OWN ENSEMBLE MEAN. KEPT IN THE LOW
POPS FOR OUR FAR NORTH HIGH ELEVATION ZONES AS IT STILL LOOKS TO BE
A LIMITED MOISTURE SYSTEM. ONE ITEM OF CONCERN IS THE POTENTIAL FOR
STRONG POST FRONTAL WINDS IN THE COLORADO RIVER VALLEY LATE SATURDAY
AND SUNDAY MORNING AS THE PRESSURE GRADIENT GETS TIGHT IN SOUTHERN
NEVADA THEN. THE POTENTIAL IS THERE FOR LAKE WIND ADVISORY LEVEL
WINDS. FOR THE REST OF THE EXTENDED PERIOD THERE IS PRETTY DECENT
MODEL AGREEMENT IN HAVING RIDGING MOVE IN AS THE SATURDAY SYSTEM
MOVES EAST QUICKLY. A WARMING TREND WILL ENSUE WITH THE RIDGE.
&&
.AVIATION...FOR MCCARRAN...TYPICAL LIGHT DIURNAL WINDS TO CONTINUE
THROUGH TODAY AND THIS EVENING. HIGH LEVEL CIRRUS CEILINGS WILL
CONTINUE THROUGH TODAY AND INTO THURSDAY. TOWARDS MIDNIGHT TONIGHT
AND INTO THURSDAY AFTERNOON THERE IS THE POTENTIAL FOR HIGH WINDS
OVER THE WEST SIDE OF THE LAS VEGAS VALLEY IN ADVANCE OF A FRONT
EXPECTED TO MOVE THROUGH LATE THURSDAY. THIS MAY SET UP SOME
TURBULENT CONDITIONS AND POSSIBLE WIND SHEAR PROBLEMS.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...TRANQUIL CONDITIONS EXPECTED THROUGH TODAY WITH
CONTINUED LIGHT DIURNAL WINDS. HIGH LEVEL CIRRUS CEILINGS WILL
CONTINUE THROUGH WEDNESDAY. A COLD FRONT WILL SWEEP ACROSS THE AREA
ON THURSDAY...RESULTING IN INCREASED WINDS...INCREASED CLOUD
COVER...AND PRECIPITATION IN THE FORM OF VALLEY RAIN SHOWERS AND
MOUNTAIN SNOW...PRIMARILY ACROSS INYO COUNTY CALIFORNIA...NORTH OF
LAS VEGAS IN NEVADA...AND IN NORTHERN MOHAVE COUNTY AZ THURSDAY
AFTERNOON AND EARLY FRIDAY. THE SIERRA AND SOUTHERN NEVADA MOUNTAIN
RANGES COULD POSSIBLY EXPERIENCE STRONG DOWNSLOPE WINDS ON THEIR
EAST SIDES LATE WEDNESDAY NIGHT AND THURSDAY MORNING.
