AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
355 AM PST TUE FEB 15 2011

.SYNOPSIS...THE AREA WILL CONTINUE TO EXPERIENCE ABOVE NORMAL
TEMPERATURES TODAY AS WE AWAIT THE ARRIVAL OF A PACIFIC STORM.
SOUTHWEST TO WEST WINDS WILL INCREASE ON WEDNESDAY LEADING TO WINDY
CONDITIONS AREAWIDE. THE EASTERN SIERRA SLOPES WILL SEE WINTER STORM
CONDITIONS WEDNESDAY WITH A COMBINATION OF HEAVY SNOW AND STRONG
WINDS. ELSEWHERE WIDESPREAD MOUNTAIN SNOW AND SCATTERED VALLEY
RAIN WILL OCCUR WEDNESDAY THROUGH THURSDAY MORNING. ANOTHER PERIOD
OF UNSETTLED WEATHER STARTS AGAIN FRIDAY AND CONTINUES INTO THE
WEEKEND AS THE MAIN STORM SYSTEM SLOWLY MOVES ACROSS THE REGION.
&&

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT...SATELLITE SHOWS
EXTENSIVE AREA OF COLD AIR ENCOMPASSING THE EASTERN PACIFIC
ASSOCIATED WITH LONGWAVE TROUGH. ALONG THE SOUTHERN PERIPHERY OF
TROUGH...VARIABLE MID/HIGH CLOUDS WILL CONTINUE TO STREAM OVERHEAD
TODAY WHILE TEMPERATURES REMAIN MILD. COASTAL AREAS FROM NORTHERN
CALIFORNIA NORTHWARD WILL BE UNDER THE GUN TODAY WITH WIDESPREAD
PRECIPITATION OCCURRING IN ASSOCIATION WITH A COLD FRONT AND MOIST
ONSHORE FLOW.

THE AREA OF PRECIPITATION WILL GRADUALLY BE DRIVEN SOUTH TONIGHT
INTO CENTRAL CALIFORNIA/LAKE TAHOE AREA TONIGHT AS A SHORTWAVE
APPROACHES THE CALIFORNIA COAST. OVER THE PAST 24 HOURS MODELS NOT
DIGGING THIS WAVE AS FAR SOUTH AND SHIFT THE SHORTWAVE ACROSS
CENTRAL NEVADA WEDNESDAY NIGHT. DUE TO THE WESTERLY TRAJECTORY OF
THIS SHORTWAVE AND INFLUX OF MOISTURE THE WESTERN SLOPES OF THE
SIERRA WILL RECEIVE MUCH OF THE PRECIPITATION WITH THE GREAT BASIN
AND MOJAVE DESERT GETTING ONLY SOME LEFTOVERS. GREATEST SNOWFALL
RATES WILL OCCUR WEDNESDAY MORNING BEFORE TAPERING OFF IN THE LATE
AFTERNOON HOURS. THE SNOW LEVEL WILL START OUT ABOVE 7000 FEET EARLY
WEDNESDAY MORNING AND FALL TO 4000 FEET WEDNESDAY AFTERNOON. WILL
CONTINUE WITH THE WINTER STORM WATCH TO COVER FOR THE HEAVY SNOW AND
STRONG WINDS. THE HIGHEST ELEVATIONS COULD SEE 12 TO 18 INCHES. AS
FOR THE SPRING MOUNTAINS/SHEEP RANGE AND MOUNTAINS IN LINCOLN COUNTY
IT APPEARS A LOW END ADVISORY EVENT IS POSSIBLE WITH 3 TO 5 INCHES.
HERE SNOW LEVELS WILL START OUT AROUND 7000 FEET AND FALL TO THE
VALLEY FLOORS OF LINCOLN COUNTY WEDNESDAY NIGHT. FOR THE SPRING
MOUNTAINS THE SNOW LEVEL WILL FALL TO 5000-5500 FEET AS AGAIN COLDER
AIR WILL NOT BE DRIVEN AS FAR SOUTH.

THE MORE SIGNIFICANT IMPACT WILL LIKELY BE THE WIND ON WEDNESDAY AS
ALL AREAS WILL EXPERIENCE WINDY CONDITIONS. HOISTED A HIGH WIND
WATCH WITH THIS PACKAGE AS MODELS SHOWS A BAND OF 50-60 KNOT 700 MB
WINDS RUNNING FROM WESTERN SAN BERNARDINO/INYO COUNTIES NORTHEAST
ACROSS SOUTHERN NYE AND LINCOLN COUNTIES. GUSTS IN EXCESS OF 60 MPH
POSSIBLE. AT ANY RATE A WIND ADVISORY WILL LIKELY BE NEEDED FOR THE
ENTIRE AREA TOMORROW WITH A FEW ZONES POTENTIALLY BEING UNDER A HIGH
WIND WARNING.

THE WIND AND PRECIPITATION WILL START TO WIND DOWN SOME AFTER
MIDNIGHT THURSDAY AS THE SHORTWAVE MOVES EAST INTO UTAH. A BOUNDARY
LEFT ACROSS SOUTH CENTRAL NEVADA ON THURSDAY MAY THE FOCUS FOR
ADDITIONAL SHOWERS THURSDAY WHILE THE REMAINDER OF THE AREA WILL BE
DRY BUT STILL BREEZY. THURSDAY STILL LOOKS TO BE THE COOLEST DAY
WITH HIGH SOME 6 TO 12 DEGREES BELOW NORMAL.

.LONG TERM...BY FRIDAY OUR ATTENTION WILL TURN TO AN UPPER LOW THAT
IS SHOWN TO DIVE SOUTHWARD ALONG THE WEST COAST TOWARDS CALIFORNIA.
THE MODELS ARE IN EXCELLENT AGREEMENT ON THIS FEATURE EXISTING BUT
STILL SHOWING SOME SPREAD IN THE TIMING OF ENERGY ASSOCIATED WITH
IT. THE INITIAL ISSUE AND ONE THAT HAS BEEN A BIG CHALLENGE THE PAST
FEW NIGHTS IN FORECASTING IS HOW QUICKLY DOES THE PRECIPITATION
SPREAD INTO OUR AREA WITH THIS FEATURE. THE ECMWF IS THE FASTEST AT
SPREADING PRECIPITATION IN WITH THE GFS MUCH SLOWER. GIVEN THE ECMWF
HAS BEEN MORE CONSISTENT FROM RUN TO RUN WITH QPF PLACEMENT AS WELL
AS THE LOOK OF HOW IT HANDLES THE ENERGY ASSOCIATED WITH IT ON THE
00Z RUN I HAVE OPTED TO FOLLOW IT MORE AND AS A RESULT KEPT IN POPS
FOR FRIDAY AND FRIDAY NIGHT OVER THE NORTHERN AND WESTERN CWFA. FROM
LAS VEGAS SOUTH AND EAST IT LOOKS DOUBTFUL MUCH PRECIPITATION WILL
MATERIALIZE ON FRIDAY IN THE LATE MORNING AND AFTERNOON AND THUS I
DELAYED ANY POPS HERE UNTIL FRIDAY NIGHT. GIVEN THE SOMEWHAT SLOWER
ARRIVAL OF THIS SYSTEM INHERITED FORECAST HIGHS FOR FRIDAY WERE TOO
LOW AND THUS I RAISED THEM ALONG WITH LOWS FOR FRIDAY NIGHT.

BY SATURDAY INTO SATURDAY NIGHT THE LATEST MODELS ARE ALL IN GOOD
AGREEMENT WITH DROPPING A CLOSED UPPER LOW DOWN TOWARDS POINT
CONCEPTION AND DRIVING A POTENT 150 KT JET STREAK AT 250 MB RIGHT UP
I-15. PAST LOCAL STUDIES HAVE SHOWN THIS TO BE A GOOD SET UP FOR
HEAVY PRECIPITATION IN THE COLD SEASON AND GIVEN THE DECENT PLUME OF
SUBTROPICAL MOISTURE THAT LOOKS TAPPED WITH FORECAST PWATS OFF THE
GFS EXCEEDING A HALF AN INCH ACROSS THE AREA THERE IS THE POTENTIAL
FOR HEAVY PRECIPITATION OVER SOME PART OF OUR AREA ON SATURDAY
AFTERNOON AND NIGHT. POPS WERE RAISED DRAMATICALLY IN THIS TIME
FRAME AS PVA WILL BE PRESENT AND THE MOISTURE IS THERE. ALSO ADDING
SUPPORT FOR THIS WAS THE GFS ENSEMBLE MEAN WAS INDICATING A CHUNK OF
OUR AREA IN THE 80-100 PERCENT PROBABILITY OF SEEING AT LEAST A
TENTH OF AN INCH OF PRECIPITATION. GIVEN THE SUBTROPICAL TAP SNOW
LEVELS WILL START OUT AT 3500-5000 FEET BEFORE FALLING ON SATURDAY
NIGHT AS THE CLOSED LOW APPROACHES. BY THE TIME THE CLOSED LOW
APPROACHES SATURDAY NIGHT PRECIPITATION WILL BECOME MORE SCATTERED
AND CONVECTIVE IN NATURE AND IF WE SEE A THUNDERSTORM OR TWO THIS
WILL BE WHEN IT OCCURS COURTESY OF THE COLD POOL ALOFT MOVING IN.
SNOW LEVELS WILL ALSO DROP THEN TO 3000-3500 FEET AND IF WE GET
SNOW IN ANY LOWER VALLEYS THIS WOULD BE THE BEST TIME FOR IT.

SCATTERED SHOWERS WILL LINGER INTO SUNDAY AS THE LOW MOVES ACROSS
THE AREA AND TAPER OFF BY SUNDAY AFTERNOON INTO SUNDAY NIGHT AS THE
LOW DEPARTS. THE LATEST MODELS HAVE BACKED OFF SOMEWHAT ON THE COLD
FOR MONDAY AS THEY FLATTEN THE FLOW ALOFT OUR MORE BUT I STILL DON'T
BUY IT ENTIRELY GIVEN THE COLD LOW THAT IS STILL EXITING AND AS A
RESULT UNDERCUT MEX AND GFS ENSEMBLE GUIDANCE FOR LOWS. AFTERWARDS
ANOTHER UPPER TROUGH LOOKS TO DROP SOUTHEASTWARD MONDAY NIGHT INTO
TUESDAY BRINGING THE POTENTIAL FOR MORE PRECIPITATION TO THE AREA
ESPECIALLY THE NORTHEASTERN PORTIONS AS WELL AS GUSTY WINDS.
TROUGHING REMAINS OVER THE WEST OUT TOWARDS THE END OF NEXT WEEK AND
YET ANOTHER SYSTEM WILL LIKELY BE IN THE WORKS BY THEN.
&&

.AVIATION...FOR MCCARRAN...SOUTH-SOUTHWEST WINDS AT 4-8 KTS WILL
CONTINUE UNTIL JUST BEFORE DAYBREAK. FROM DAYBREAK THROUGH 18Z OR SO
WINDS WILL BECOME LIGHT AND VARIABLE BEFORE INCREASING OUT OF THE
SOUTH AT 8-12 KTS BY TUESDAY AFTERNOON. VARIABLE AMOUNTS OF CLOUDS
AOA 18K FEET ARE EXPECTED THROUGH TONIGHT. AN ACTIVE WEATHER
PATTERN WILL BRING STRONGER SOUTHWEST WINDS TO THE AREA ON WEDNESDAY
FOLLOWED BY SEVERAL PERIODS OF PRECIPITATION FROM WEDNESDAY THROUGH
SUNDAY MORNING. LOWER CIGS AND VSBY WILL BE POSSIBLE IN THIS TIME
FRAME.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...SOUTH TO SOUTHWEST WINDS WILL INCREASE TO BETWEEN 15
AND 25 KTS ACROSS MUCH OF THE REGION TUESDAY AFTERNOON. SCT-BKN
CLOUDS MAINLY AOA 15K-18K FEET THROUGH TONIGHT. AN ACTIVE
WEATHER PATTERN WILL BRING STRONG WINDS TO THE AREA WEDNESDAY ALONG
WITH PERIODS OF PRECIPITATION FROM WEDNESDAY THROUGH SUNDAY. LOWER
CIGS INCLUDING MOUNTAIN OBSCURATIONS AS WELL AS LOWER VSBY WILL BE
LIKELY IN THIS TIME FRAME WITH CONDITIONS DROPPING TO MVFR OR LOWER.
