Area forecast discussion, Apr 22, 3:15 AM PDT, 11 hours 32 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
315 AM PDT TUE APR 22 2008
.SYNOPSIS...AN AREA OF LOW PRESSURE OFF THE PACIFIC NORTHWEST COAST
WILL MOVE INLAND WEDNESDAY AND BRING ANOTHER ROUND OF WIND TO THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN. THE WIND WILL
SUBSIDE LATER IN THE WEEK...AND TEMPERATURES WILL RISE TO SEVERAL
DEGREES ABOVE NORMAL OVER THE WEEKEND.
&&
.SHORT TERM...WATER VAPOR LOOP SHOWS SHORTWAVE TROUGH THAT UNDERCUT
BLOCKING HIGH OVER THE GULF OF ALASKA BEING ABSORBED BY DEEP UPPER
LOW OFF THE PACIFIC NORTHWEST COAST THIS MORNING. FOR THE PAST WEEK
MODELS HAVE HAD A GOOD HANDLE ON THE LONGWAVE PATTERN. TROUGH WILL
START MOVING EAST TOWARD THE OREGON COAST TODAY WITH SOUTHWEST FLOW
INCREASING ACROSS THE AREA. MODEL 700 MB WINDS NOT AS STRONG AS
SHOWN YESTERDAY SO DID TONE DOWN THE WIND GUSTS. WEAK SHORTWAVE
EJECTS EAST ACROSS THE GREAT BASIN TONIGHT AND WITH INCREASING
ONSHORE FLOW IN CENTRAL CALIFORNIA LEFT IN A SLIGHT CHANCE OF
SHOWERS SPILLING OVER THE SIERRA CREST INTO INYO COUNTY. KEPT THE
LOW POPS FOR THE MOUNTAINS OF NORTHERN LINCOLN COUNTY WEDNESDAY AS
MAIN PORTION OF THE TROUGH MOVES ACROSS NORTHERN NEVADA. SURFACE
PRESSURE GRADIENT AND WINDS ALOFT INCREASE ACROSS THE MOJAVE DESERT
WEDNESDAY. STRONGEST WINDS WILL BE ACROSS WESTERN SAN BERNARDINO
COUNTY AND WE WILL LIKELY NEED A WIND ADVISORY IN THE AFTERNOON AND
EVENING. WIND GUSTS WILL BE STRONG ENOUGH ALONG WITH DRY CONDITIONS
THAT A FIRE WEATHER WATCH HAS BEEN ISSUED FOR MUCH OF CLARK...MOHAVE
AND SAN BERNARDINO COUNTIES. WARMING OF THE 850 MB TEMPERATURES AND
BETTER MIXING THIS AFTERNOON WILL GIVE A DECENT BOOST TO HIGH
TEMPERATURES. SLIGHT COOL DOWN WEDNESDAY AND THURSDAY FOLLOWING
TROUGH PASSAGE.
.LONG TERM...A LOOK AT 00Z MODEL OUTPUT FOR NEXT WEEKEND DID LITTLE
TO DETER THIS FORECASTER FROM REMAINING WITH THE STATUS QUO. THE
LATEST GFS HAD A DRAMATICALLY DIFFERENT TAKE ON THE EVOLVING WEATHER
PATTERN FOR THE WEEKEND. IT NOW FORECASTS AN INSIDE SLIDER MOVING
FROM WASHINGTON STATE FRIDAY INTO UTAH SATURDAY AND THEN CLOSING OFF
A LOW OVER THE FOUR CORNERS REGION SUNDAY. A SHARP COLD FRONT IS
DRAWN ACROSS THE AREA SATURDAY AND SUNDAY RESULTING IN MUCH...MUCH
COOLER TEMPERATURES THAN IS CURRENTLY FORECAST AND WHAT WAS
FORECASTED BY THE MODEL JUST 24 HRS AGO. IN ADDITION...IT FORECASTS
A LOT MORE WIND. THE GFS ENSEMBLE MEMBERS WHICH WERE PREVIOUSLY
SHOWING DECENT AGREEMENT ARE NOW BASICALLY SPREAD BETWEEN TWO CAMPS
WITH SOME MEMBERS SUPPORTING THE WARMER SOLUTION OF YESTERDAY AND
OTHER MEMBERS SUPPORTING THE NEW COOLER SOLUTION. THE NEW MEN TEMP
GUIDANCE BEARS THIS OUT WITH 17 DEGREES OF SPREAD BETWEEN HIGH AND
LOW MEMBERS ON SATURDAY AND 20 DEGREES ON SUNDAY. LOADING THE RAW
TEMPERATURE DATA INTO THE GRIDS FROM THE 00Z GFS GAVE A 72 FOR
SATURDAY VS A 91 WHEN USING YESTERDAY/S DATA. ALTHOUGH THE GFS WAS
DISCOUNTED...THE MAJOR CHANGE DEPICTED BY THIS SOLUTION MERITS
MENTIONING SINCE IT WOULD REQUIRE A DRAMATIC CHANGE TO THE FORECAST
WERE IT TO PAN OUT. BUT FOR NOW...THE ECMWF/GEM PROVIDED A GOOD
COMPROMISE SINCE THEY ACKNOWLEDGE THE SHORTWAVE MOVING INTO THE
PACIFIC NW COAST FRIDAY BUT KEEP THE TRACK WELL NORTH AND EAST OF
THE AREA. THE RESULT IS TEMPERATURES THAT ARE JUST SLIGHTLY COOLER
THAN WHAT WAS FEATURED IN THE PREVIOUS FORECAST PACKAGE. IN
SHORT...THE FORECAST STILL CALLS FOR DRY CONDITIONS WITH A WARMING
TREND THROUGH EARLY NEXT WEEK. HOWEVER...CHECK BACK OVER THE NEXT
DAY OR TWO FOR UPDATED FORECAST TRENDS...ESPECIALLY BEFORE MAKING
OUTDOOR PLANS FOR THE WEEKEND.
&&
.FIRE WEATHER...A FIRE WEATHER WATCH HAS BEEN ISSUED FOR PARTS OF
THE AREA BETWEEN 11 AM AND 8 PM WEDNESDAY. SOUTHWEST WINDS AROUND 20
MPH WITH GUSTS AROUND 35 MPH IN CLARK AND MOHAVE COUNTIES...OVER 40
MPH IN WESTERN SAN BERNARDINO COUNTY WILL DEVELOP WEDNESDAY
AFTERNOON. POOR RELATIVE HUMIDITY RECOVER IS EXPECTED ONCE AGAIN
TONIGHT MEANING HUMIDITY READINGS WILL EASILY FALL BELOW 15 PERCENT
BY LATE MORNING. DUE TO THE LACK OF ANY PRECIPITATION OVER THE PAST
SEVERAL MONTH FINE FUELS ARE VERY DRY AT ELEVATIONS BELOW 7000
FEET. &&
.AVIATION...FOR MCCARRAN...LIGHT WINDS IN THE MORNING ARE EXPECTED
TO INCREASE THIS AFTERNOON...BECOMING 10-15 KTS WITH GUSTS OVER 20
KTS AS A STORM SYSTEM APPROACHES THE AREA. SOME HIGH LEVEL CLOUDS
ARE POSSIBLE BUT WILL NOT BE SIGNIFICANT TO AIRPORT OPERATIONS. THE
STORM THEN MOVES ACROSS THE AREA WEDNESDAY BRINGING STRONGER WINDS
TO THE AIRPORT.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...AN INCREASE IN SOUTHERLY WINDS EXPECTED THIS AFTERNOON
AS A PACIFIC STORM SYSTEM APPROACHES THE AREA. SOME HIGH LEVEL CLOUD
COVER EXPECTED TO ACCOMPANY THE SYSTEM. THE STORM WILL MOVE ACROSS
THE REGION WEDNESDAY BRINGING WIDESPREAD WINDY CONDITIONS TO THE
AREA.
