AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
310 PM PST WED FEB 25 2004
.SYNOPSIS...A STRONG PACIFIC STORM PRODUCING HEAVY SNOW IN THE
SOUTHERN SIERRA WILL BRING WIDESPREAD RAIN AND SNOW ACROSS THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN LATE TONIGHT AND THURSDAY.
A COLD AREA OF LOW PRESSURE WILL THEN SETTLE OVER THE GREAT BASIN
FRIDAY FOR SCATTERED RAIN AND SNOW SHOWERS AND BELOW NORMAL
TEMPERATURES. THE SYSTEM WILL EXIT TO THE EAST SATURDAY LEAVING
DRIER WEATHER FOR THE WEEKEND.
&&
.SHORT TERM...PRECIPITATION WAS BEGINNING TO SPREAD INTO WESTERN SAN
BERNARDINO COUNTY THIS AFTERNOON AFTER THE INITIAL PLUME OF MOISTURE
SLAMMED INTO THE SIERRA. THE PLUME OF LOW AND MID LEVEL MOISTURE
EXTENDS WELL OFF THE SOUTHERN CALIFORNIA COAST AND ENERGY ROUNDING
THE BASE OF THE BROAD CLOSED LOW WILL PRODUCE A GOOD COMBINATION OF
MOISTURE AND UPWARD FORCING SWEEPING EAST-SOUTHEAST ACROSS THE
FORECAST AREA TONIGHT AND THURSDAY MORNING. THE BEST FOCUS FOR
PRECIP ACROSS SOUTHEAST CALIFORNIA/SOUTHERN NEVADA SHOULD OCCUR
BETWEEN 4 AM AND NOON THEN SHIFTS ACROSS MOHAVE COUNTY DURING THE
AFTERNOON. THE 12Z/18Z ETA TRENDS WERE PREFERRED AND GENERALLY
FOLLOWED. DESERTS COULD SEE QUARTER TO HALF-INCH AMOUNTS OF QPF AND
THE MOUNTAINS STILL SHOULD SEE A FOOT OR SO OF NEW SNOW. WILL
UPGRADE THE WATCH TO A WARNING FOR THE SOUTHERN NEVADA MOUNTAINS AND
TO A SNOW ADVISORY FOR LINCOLN COUNTY. SINCE MOST OF THE PRECIP WILL
OCCUR DURING THE DAY OVER MOHAVE COUNTY...SNOW LEVELS SHOULD
GENERALLY BE ABOVE 6500 AND AMOUNTS OF 3-5 INCHES MAY FALL ABOVE
7000 FEET. WILL NOT ISSUE A SNOW ADVISORY THERE. THE COLD POOL OF
THE BROAD UPPER LOW THEN SETTLES OVER THE REGION FRIDAY FOR SHOWERY
WEATHER AND THEN PULLS EAST SATURDAY FOR A DRIER NORTHERLY FLOW AND
DIMINISHING PRECIP COVERAGE FROM WEST TO EAST.
&&
.LONG TERM...EXTENDED MODELS ARE BEGINNING TO DIFFER WITH THE SYSTEM
ON MONDAY WITH THE GFS SHOWING A DEEP TROUGH OVER THE WESTERN U.S.
INTO TUESDAY. THE GFS CONTINUES TO SHOW A DEEP TROUGH CARVING OUT
OVER THE WESTERN STATES MONDAY INTO TUESDAY. THIS IS IN RESPONSE TO
A STRONG NORTHERN STREAM SHORTWAVE WHICH THE ECMWF...UKMET...AND GFS
ALL SHOW SOUTH OF THE ALEUTIANS ON FRIDAY...BUT ONLY THE GFS RETAINS
A WELL DEFINED WAVE INTO MONDAY. THE ECMWF SHOWS NO HINT OF THE WAVE
ON MONDAY...WITH ONLY BROAD CYCLONIC CURVATURE OVER THE
INTERMOUNTAIN WEST ON TUESDAY...AND HEIGHTS 60-100 METERS HIGHER
THAN THE GFS. MODELS ARE SHOWING THAT THE BEST AREA FOR MOISTURE
WILL REMAIN OVER THE EASTERN HALF OF THE CWA LATE MONDAY INTO
TUESDAY AND HAVE GONE AHEAD AND LOWERED POPS SLIGHTLY OVER THE WEST.
ANOTHER SYSTEM IS FORECAST TO DROP INTO THE CWA THURSDAY AND WILL
CONTINUE WITH THE SLIGHT CHANCES THAT ARE ALREADY IN THE FORECAST. &&
.AVIATION...RAIN SHOWERS ARE EXPECTED TO MOVE INTO THE LAS VEGAS
VALLEY OVERNIGHT WITH THE GREATEST CHANCE EXPECTED BETWEEN 12Z AND
18Z THURSDAY. THERE WILL BE THE POTENTIAL OF CEILINGS LOWERING TO

TO TAPER OFF BY MIDDAY WITH ISOLATED SHOWERS THROUGHOUT THE
REMAINDER OF THE AFTERNOON.
