AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
915 AM PDT SAT APR 15 2006

.SYNOPSIS...DRY WEST TO SOUTHWEST FLOW WILL BE OVER THE AREA TODAY
AND TONIGHT. A LOW PRESSURE SYSTEM WILL MOVE ACROSS CALIFORNIA AND
NEVADA LATE SUNDAY THROUGH EARLY MONDAY BRINGING BREEZY TO WINDY
CONDITIONS ALONG WITH A CHANCE OF SHOWERS TO THE SOUTHERN GREAT
BASIN.
&&

.UPDATE...LOW CLOUDS CONTINUING ACROSS MUCH OF CENTRAL NYE...LINCOLN
AND NORTHERN MOHAVE COUNTY THIS MORNING AS REMNANTS OF SHORT WAVE
CONTINUE TO SLOWLY DISSIPATE. EXPECT CLOUDS TO CONTINUE TO DISSIPATE
INTO THE AFTERNOON....WHILE MOSTLY CLEAR SKIES EXPECTED ELSEWHERE.
NEXT TROUGH STILL ON TRACK TO BEGIN MOVING INTO THE AREA SUNDAY AND
MONDAY WITH MAIN EVENT BEING WINDS ACROSS MUCH OF THE AREA. OVERALL
CURRENT FORECAST ON TRACK. UPDATE TO ZONES ALREADY SENT TO REFLECT
CURRENT CONDITIONS.
&&

.PREV DISCUSSION...245 AM PDT SHORT TERM...TROUGH EXITING TO THE
EAST WITH CLOUDS DECREASING EARLY THIS MORNING. DRY WEST TO
SOUTHWEST FLOW WILL BE OVER THE FORECAST AREA TODAY THROUGH MOST OF
SUNDAY. MOISTURE WILL INCREASE OVER THE SIERRA LATE SUNDAY AS AN
UPPER TROUGH MOVES TO THE NORTHERN CALIFORNIA COAST. SOUTHWEST FLOW
WILL INCREASE BY SUNDAY AFTERNOON RESULTING IN BREEZY TO WINDY
CONDITIONS MOST ZONES. THE TROUGH WILL MOVE TO NEAR THE CA/NV BORDER
SUNDAY NIGHT SPREADING A CHANCE OF SHOWERS ACROSS THE FAR NORTHERN
PORTION OF THE FORECAST AREA WITH BREEZY TO WINDY CONDITIONS
CONTINUING. TROUGH PROGGED TO MOVE ACROSS NEVADA INTO UTAH MONDAY
WITH THE BEST CHANCE OF SHOWERS OVER LINCOLN COUNTY IN THE MORNING
AND PRECIPITATION CHANCES ENDING ELSEWHERE ACROSS THE NORTH.
TEMPERATURES WILL BE COOLER BEHIND THE TROUGH AND ASSOCIATED COLD
FRONT ON MONDAY. LOOKING FOR A SHIFT TO NORTHERLY WINDS BEHIND THE
FRONT AS WELL.

.LONG TERM...BOTH THE GFS AND EURO SHOW A WEAK BAGGY TROUGH OVER THE
WESTERN U.S. WEDNESDAY AND THURSDAY...BUT OTHER THAN A FEW MID AND
HIGH CLOUDS AND SLIGHTLY BELOW NORMAL TEMPERATURES...NOT REALLY
EXPECTING MUCH. BIGGER CHANGES OCCUR ON FRIDAY WITH THE GFS DROPPING
A CUTOFF LOW THROUGH NORTHERN CA AND INTO SOUTHERN NEVADA BY FRIDAY
NIGHT. PREVIOUS GFS RUN KEPT THE LOW OFF SHORE AND BROUGHT MAINLY
BREEZY TO WINDY CONDITIONS TO THE AREA. WITH THIS NEW TRACK THE GFS
HAS INCREASED QPF OVER THE CWA ALONG WITH SIGNIFICANTLY COOLER
TEMPERATURES. THE EURO IS ALSO SHOWING A CUTOFF LOW...BUT IS KEEPING
IT WELL OFF SHORE. HAVE DECIDED TO LEAN MORE WITH THE EURO AND KEEP
THINGS AT A SLOWER PACE...BUT DID ADD SLIGHT CHANCE POPS FOR THE
HIGHER TERRAIN ON FRIDAY. DID NOT WANT TO TOTALLY DISCOUNT THE
GFS...BUT DID NOT WANT TO HIT ANYTHING TO HARD RIGHT NOW. KEPT
THINGS DRY ON SATURDAY AND SUNDAY...BUT THIS IS MAINLY DUE TO THE
FACT THAT THESE MODELS COULD SHOW SOMETHING COMPLETELY DIFFERENT ON
THE NEXT RUN.

.AVIATION...TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS... KVGT... KDRA...
KBIH... KDAG...KEED.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
