AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
309 PM PST THU DEC 20 2007

.SYNOPSIS...A STRONG COLD FRONT WILL SWEEP SOUTHEAST ACROSS SOUTHERN
NEVADA AND THE LOWER COLORADO RIVER VALLEY TONIGHT. GUSTY SOUTHWEST
WINDS WILL CONTINUE TO OCCUR AHEAD OF THE COLD FRONT WITH BLUSTERY
NORTH WINDS EXPECTED ON FRIDAY. A BRIEF PERIOD OF HEAVY SNOW IS
POSSIBLE IN LINCOLN COUNTY THIS EVENING. OTHERWISE ISOLATED TO
SCATTERED SHOWERS WILL ACCOMPANY THE FRONTAL PASSAGE. BELOW NORMAL
TEMPERATURES AND DRY CONDITIONS CAN BE EXPECTED THROUGH THE WEEKEND.
&&

.SHORT TERM...TIME WAS SPENT FOCUSING ON THE NEXT 24-30 HOURS AS
REST OF THE WEEKEND LOOKS RELATIVELY QUIET. STRONG COLD FRONT
CURRENTLY RUNNING FOR WENDOVER-TONOPAH-BISHOP. 12Z/18Z NAM HAS BEEN
CONSISTENT INDICATING SEVERAL HOURS OF FOCUSED LIFT ALONG AND JUST
BEHIND THE COLD FRONT AS IT SWEEPS THROUGH LINCOLN COUNTY THIS
EVENING. DEEP ENOUGH CONVECTION OCCURRING ALONG COLD FRONT OVER
WHITE PINE COUNTY THIS AFTERNOON THAT SEVERAL LIGHTNING STRIKES HAVE
BEEN DETECTED. WILL NOT MENTION THUNDER FOR NORTHERN LINCOLN COUNTY
THIS EVENING AS BELIEVE IT WOULD BE VERY ISOLATED. CONVECTIVE ALONG
THE FRONT DOES LEAD TO THE POTENTIAL OF BRIEF HEAVY BURSTS OF SNOW
AND WILL KEEP SNOW ADVISORY POSTED WITH THE GREATEST ACCUMULATIONS
OCCURRING NORTH OF A LINE FROM RACHEL-PIOCHE-SPRING VALLEY STATE
PARK. NEXT CONCERN FOR THE SHORT TERM IS WIND. WIND ADVISORY PANNING
OUT SO FAR FOR WESTERN SAN BERNARDINO COUNTY AS I HAVE SEEN A FEW
SITE REPORTING GUSTS OVER 40 MPH. GUSTY SOUTHWEST-WEST WINDS WILL
CONTINUE AHEAD OF THE COLD FRONT THEN ABRUPTLY SHIFT TO THE NORTH.
FRONTAL PASSAGE WILL OCCUR LATE THIS AFTERNOON IN THE NORTHWEST
ZONES...AROUND 10 PM FOR LAS VEGAS...AND AROUND 3 AM PST FRIDAY
MORNING AT NEEDLES. ADVISORY LEVEL NORTH WINDS EXPECTED BEHIND THE
COLD FRONT SO HAVE ISSUED A NUMBER OF WIND ADVISORIES RUNNING FOR
LATE THIS AFTERNOON THROUGH LATE TOMORROW AFTERNOON FOR THE COLORADO
RIVER ZONES. WEAK RIDGE WILL BE OVER THE AREA SATURDAY FOLLOWED BY
THE NEXT SYSTEM MOVING ACROSS THE NORTHERN GREAT BASIN AND INTO UTAH
SUNDAY. TEMPERATURES WILL REMAIN WELL BELOW NORMAL THROUGH THE
WEEKEND.

.LONG TERM...MODELS AGREE ON A SERIES OF TROUGHS TO PASS THROUGH IN
THE MONDAY THROUGH THURSDAY TIME FRAME. THERE IS DISAGREEMENT ON THE
TRACK THE SYSTEMS TAKE AS THEY DROP SOUTH INTO OUR AREA AND THIS
LEAD TO LOWERED CONFIDENCE IN THE PRECIPITATION FORECAST. MONDAY
MORNING WILL SEE THE BACK SIDE OF A DEPARTING TROUGH TO THE EAST AS
ANOTHER IS RIGHT ON ITS HEELS AND DROPPING SOUTH. ECMWF AND GEM WANT
TO BRING THIS SYSTEM AND CLOSE IT OFF OVER THE CWA WHILE THE GFS AND
DGEX HAVE IT FURTHER TO THE EAST EARLY TUESDAY. FOR NOW KEPT MOST
POPS SILENT AND/OR NONE DUE TO DOUBT OF TRACK WHICH WOULD FAVOR WET
IF ECMWF VERIFIES AND DRYER IF GFS DOES. IN ANY CASE ALL AGREE ON
THIS BEING A FAST MOVER AND YET ANOTHER TROUGH TO DROP DOWN FROM THE
NORTHWEST ON WEDNESDAY AND THURSDAY TIME FRAME. HERE THE
DISAGREEMENT IN GREATER ON HOW FAR EAST OR WEST THE TRACK WILL BE.
DID KEEP IN THE POPS INHERITED FOR MUCH OF THE CWA THEN AS I FAVORED
THE ECMWF FORECAST WHICH HAS IT OVER THE CWA AND MOISTER. IN ALL
SCENARIOS THESE SYSTEMS WILL BRING BREEZY OR STRONGER NORTHERLY
WINDS BEHIND THEM AND THEIR ASSOCIATED FRONTS.
&&

.AVIATION...FOR MCCARRAN...THE GUSTY SOUTHWEST WINDS WILL CONTINUE
UNTIL THE FRONT PASSES THROUGH THE VALLEY IN THE 05Z-07Z TIME FRAME
THIS EVENING. THEN THE WINDS WILL SWITCH TO THE NORTHWEST TO NORTH
AND INCREASE IN SPEED WITH GUSTS TO AROUND 40KTS. THESE WINDS WILL
CONTINUE THROUGH THE REST OF NIGHT AND UNTIL 18Z FRIDAY MORNING.
WINDS WILL STAY NORTHERLY THE REST OF FRIDAY BUT GREATLY REDUCED IN
SPEED. CEILINGS WITH THE FRONTAL PASSAGE WILL DROP DOWN TO THE 6000
TO 8000 FT RANGE AND THEN GO SCT TO FEW BEFORE SUNRISE.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A STRONG COLD FRONT IS MOVING SOUTHEAST THROUGH THE
GREAT BASIN AND INTO THE MOHAVE DESERT TONIGHT. ALONG THE FRONT IN
LINCOLN COUNTY AND PART OF CENTRAL NYE COUNTIES WIDESPREAD IFR
CONDITIONS EXPECTED ALONG WITH SNOWFALL TONIGHT. SOUTH OF THE FRONT
GUSTY SOUTHWEST WINDS UP TO 40 KNOTS CAN BE EXPECTED. BEHIND THE
FRONT NORTHWEST TO WEST WINDS GUST UP TO 40 KNOTS CAN BE EXPECTED.
THIS WILL SET UP FOR TURBULENT CONDITIONS AREA WIDE THIS EVENING AND
THROUGH FRIDAY AFTERNOON.
