START OUT HIGH AROUND 9000 FEET TONIGHT...IT WILL HAVE A TREMENDOUS
AMOUNT OF MOISTURE TO WORK WITH. SNOW LEVELS ARE EXPECTED TO LOWER
TO AROUND 8000 FEET BY WEDNESDAY AFTERNOON AND LOWER FURTHER TO
AROUND 6500 FEET BY THE MORNING OF THANKSGIVING. ALTHOUGH THE BULK
OF PRECIPITATION IN ASSOCIATION WITH THIS SYSTEM WILL FALL IN THE

STILL EXIST ACROSS THE AREA FROM WEDNESDAY AFTERNOON INTO THURSDAY
MORNING THAT A HEAVY ACCUMULATION OF SNOW IS POSSIBLE...ESPECIALLY
ABOVE 8500 FEET. SNOW IS EXPECTED TO TAPER OFF ACROSS THE REGION
ON THANKSGIVING DAY AS THE SYSTEM DEPARTS TO THE EAST.

THOSE WITH TRAVEL OR RECREATIONAL PLANS TO THE SPRING MOUNTAINS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1015 AM PST MON NOV 24 2008

.SYNOPSIS...A DRAMATIC CHANGE IN THE WEATHER IS IN STORE TUESDAY
THROUGH THANKSGIVING WEEKEND. THE FIRST IN A SERIES OF PACIFIC
STORMS WILL REACH THE WEST COAST TUESDAY THEN MOVE INLAND TUESDAY
NIGHT AND WEDNESDAY...BRINGING WIDESPREAD RAIN TO THE VALLEYS AND
SNOW TO THE MOUNTAINS WEDNESDAY INTO THANKSGIVING DAY. A BRIEF BREAK
BETWEEN STORMS IS EXPECTED THURSDAY NIGHT BEFORE A SECOND PACIFIC
SYSTEM BRINGS ANOTHER CHANCE OF RAIN AND SNOW TO THE REGION NEXT
WEEKEND.
&&

.UPDATE...THE TRENDS TODAY LOOK OKAY THOUGH PERSISTENCE AND 12Z
MOS GUIDANCE INDICATE FORECAST TEMPERATURES THIS AFTERNOON MAY BE A
COUPLE DEGREES ON THE HIGH SIDE. THE 12Z GFS AND NAM SOLUTIONS ARE
LINED UP QUITE WELL WITH THE DETAILS OF THE INCOMING PACIFIC SYSTEM.
THEY BOTH SHOW A PRELIMINARY BAND OF MID LEVEL MOISTURE CROSSING THE
AREA TUESDAY WHICH COULD PRODUCE SOME LIGHT RAIN. MORE
SIGNIFICANTLY...THEY BOTH SHOW A BULLSEYE OF MOISTURE COMBINED WITH
STRONG ASCENT OVER SOUTHERN NEVADA AND THE COLORADO RIVER VALLEY
AROUND 18Z WEDNESDAY. ALSO...FORECAST SOUNDINGS INDICATE SNOW
LEVELS...QUITE HIGH...AROUND 8500-9000 FEET FOR THE SOUTHERN NEVADA
MOUNTAINS WEDNESDAY WHEN THE MAJORITY OF THE PRECIPITATION SHOULD
FALL. THE FORECAST TRENDS ARE ON TRACK...BUT SNOW LEVELS WILL NEED
TO BE RAISED AND POPS COULD PROBABLY BE INCREASED ANOTHER 10-20
PERCENT. THESE DETAILS WILL BE IMPLEMENTED IN THE NEXT ROUTINE
FORECAST PACKAGE. -ADAIR-
&&

.PREV DISCUSSION.../330 AM PST MON NOV 24 2008/

.SHORT TERM...SATELLITE CLEARLY SHOWS THE MAIN PLAYERS IN THE SHORT
TERM. THE FIRST IS A CUTOFF LOW PRESSURE SYSTEM NEAR 35N 135W
/FORMERLY THE SOUTHERN PART OF A FULL LATITUDE TROUGH WHICH SPLIT
SUNDAY/. THE SECOND IS A NORTHERN STREAM SHORTWAVE TROUGH JUST SOUTH
OF THE ALEUTIAN ISLANDS. THE THIRD IS AN AREA OF SUBTROPICAL
MOISTURE BEGINNING TO GATHER NEAR 20N 122W. YET AGAIN...THE MODELS
SHOW SIGNIFICANT DIFFERENCES IN THE EVOLUTION OF THESE FEATURES. AS
HAS BEEN THE CASE FOR A FEW DAYS NOW...THE 00Z RUN OF THE GFS WAS
FASTER THAN THE 00Z ECMWF BRINGING THE CUTOFF LOW INTO CALIFORNIA.
IN SITUATIONS INVOLVING CUTOFF LOWS...THE ECMWF IS FREQUENTLY THE
SLOWEST MODEL...AND THE GFS FREQUENTLY TRENDS TOWARDS THE ECMWF OVER
TIME. NO SUCH TREND WAS SEEN FOR THE PAST FEW DAYS...AS THE MODELS
HAVE HAD EXCELLENT RUN TO RUN CONSISTENCY. HOWEVER...THE 06Z GFS HAS
THROWN AN INTERESTING TWIST INTO THE PLOT...AS IT HAS TRENDED
DRAMATICALLY SLOWER...EVEN SLOWER THAN THE 00Z ECMWF. THE 06Z AND
18Z RUNS HAVE BEEN KNOWN TO DO ODD THINGS WHICH DO NOT PERSIST INTO
THE NEXT RUNS...SO WILL NOT JUMP ONTO THIS IDEA YET. FORECAST GRIDS
STILL LEAN TOWARD THE 00Z GFS. WOULD PREFER TO LEAN MORE TOWARD THE
SLOWER ECMWF...BUT AM SOMEWHAT CONSTRAINED BY NEIGHBORING OFFICES.
THE 00Z GFS SLOWLY MOVES THE LOW CENTER ACROSS 130W TONIGHT...WHILE
THE PLUME OF SUBTROPICAL MOISTURE GETS ENTRAINED INTO THE SOUTHEAST
QUADRANT. THE ALEUTIANS SHORTWAVE ZIPS BY TO THE NORTH
TUESDAY...LEAVING THE CUTOFF LOW BEHIND RATHER THAN PHASING WITH IT
AS WAS SHOWN IN THE MODELS LAST WEEK. THE 00Z GFS SEEMS TO SPLIT THE
SUBTROPICAL MOISTURE PLUME INTO TWO FINGERS...ONE OF WHICH RACES OFF
TO THE EAST OVER ARIZONA...AND ONE OF WHICH DEVELOPS INTO A BAND OF
HEAVY PRECIP THAT TARGETS THE SOUTHERN CALIFORNIA COASTAL AND
MOUNTAIN AREAS TUESDAY NIGHT. THIS FINGER OF MOISTURE STILL HAS THE
POTENTIAL TO BRING SIGNIFICANT PRECIP TO THE SIERRA...AND SNOW
LEVELS WILL FALL AS THE LOW MOVES INLAND...SO THE WINTER STORM WATCH
STILL LOOKS GOOD. THE LOW CENTER SLUGGISHLY MOVES OVER CALIFORNIA
AND CENTRAL NEVADA WEDNESDAY INTO THANKSGIVING MORNING AS NORTHERN
STREAM RIDGING DEVELOPS OVER BRITISH COLUMBIA AND ALBERTA...WITH
PRECIP CHANCES CONTINUING AND TEMPERATURES TAKING A TUMBLE. THE
ECMWF IS ABOUT 6-12 HOURS SLOWER AND ABOUT 200 MILES FARTHER SOUTH
WITH THE LOW TRACK DURING THIS PERIOD...MEANING LOWER THAN NORMAL
CONFIDENCE IN THE DETAILS. THE OVERALL MESSAGE REMAINS THE
SAME...BIG CHANGES ON THE WAY.

.LONG TERM...QUICK LOOK AT 24/06Z GFS PUTS IT CLOSER TO THE 24/00Z
ECMWF IN PLACING THE UPPER LOW OVER SOUTHERN NEVADA THURSDAY MORNING
WHILE OLDER 00Z RUN HAD IT FURTHER NORTH. IN ANY CASE STICKING CLOSE
TO SLIGHTLY FASTER GFS SPEED OF THE OLDER 00Z RUN. I DID LOWER POPS
SOME ON THURSDAY AND FRIDAY MORNING AS SYSTEM EXITS THE AREA. WRAP
AROUND AND LINGERING MOISTURE WILL STILL LEAVE A SLIGHT CHANCE TO
CHANCE OF PRECIPITATION OVER CWA WITH BEST AREA BEING MOHAVE COUNTY.

IT IS THE SECOND SYSTEM DUE TO APPROACH THE REGION FROM THE NORTH
FRIDAY AFTERNOON AND EVENING THAT IS THE TOUGHER FORECAST. MODELS
STILL FAR APART ON SOLUTION INITIALLY BUT THE GFS IS STILL DRAWING
CLOSER TO THE ECMWF SOLUTION...WHICH IS MOSTLY AN INSIDE SLIDER
SYSTEM THAT IS DRIER AND MORE OF A WIND PROBLEM FORECAST. FOR NOW
HAVE LEFT THE POPS ALONE FOR FRIDAY AFTERNOON AS GFS STAYING
CONSISTENT ON BRINGING A BIT OF MOISTURE TO THE AREA EVEN WITH ITS
LATEST FURTHER EAST TRAJECTORY. HOWEVER...AFTER A QUICK LOOK AT 06Z
RUN AND IF THE NEXT RUN CONTINUES THE EASTWARD MOVEMENT OF SYSTEM
WILL NEED TO LOWER POPS. DID UP THE WINDS FRIDAY AND SATURDAY AS
BOTH MODELS INDICATE HIGH PRESSURE MOVING IN BEHIND LOW/TROUGH AND
TIGHTENING GRADIENTS. DID NOT INCREASE TO BREEZY LEVELS. IF ECMWF
DOES LOOK TO BE THE BETTER SOLUTION STRONGER WINDS WILL LIKELY BE
NEEDED IN GRIDS AND IN TEXT VERBIAGE FOR FRIDAY/SATURDAY WITH THE
DRIER INSIDE SLIDER ECMWF SCENARIO.

SUNDAY ONWARDS THEIR IS SOMEWHAT BETTER MODEL AGREEMENT AS LOW DROPS
SOUTH OF OUR CWA. ECMWF HAS IT FURTHER SOUTH AND OVER GULF OF
CALIFORNIA WHILE GFS IS OFF THE WEST COAST OF BAJA. IN ANY CASE IT
WILL MAKE FOR LOWER POPS IN OUR AREA AND A SLOW WARMING TREND BEGINS.
&&

.AVIATION...FOR MCCARRAN...LIGHT SOUTHWEST WINDS THIS EARLY MORNING
WILL GIVE WAY TO LIGHT AND VARIABLE WINDS LATER THIS MORNING AND
AFTERNOON. CHANGE STILL ON TAP BEGINNING TONIGHT AS CLOUD COVER
INCREASES. TUESDAY NIGHT WILL SEE CEILINGS LOWER TO NEAR 5000 FEET
AND SEE RAIN SHOWERS AROUND THE VALLEY ON INTO WEDNESDAY. THURSDAY
AND EARLY FRIDAY WILL SEE A REPRIEVE BEFORE ANOTHER SYSTEM LATE
FRIDAY BRINGS A CHANCE FOR MORE RAIN AND LOWER CEILINGS... BUT
UNCERTAINTY IS HIGH AS TO HOW MOIST IT WILL BE.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...GENERALLY LIGHT AND VARIABLE WINDS ALONG WITH HIGH
LEVEL CIRRUS TO CONTINUE THROUGH TODAY. CHANGE STILL ON TAP
BEGINNING TONIGHT AS CLOUD COVER INCREASES. TUESDAY NIGHT WILL SEE
CEILINGS LOWER TO NEAR 5000 FEET AND SEE RAIN SHOWERS AROUND THE
