AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LAS VEGAS NV
955 AM PST MON FEB 13 2006

.SYNOPSIS...A WEAK LOW PRESSURE SYSTEM WILL DRAG SOME HIGH CLOUDS
ACROSS THE REGION TODAY BUT TEMPERATURES ARE EXPECTED TO WARM
SEVERAL DEGREES. A DRY WESTERLY FLOW WILL DEVELOP BEHIND THIS SYSTEM
TONIGHT AND TUESDAY BEFORE A STRONG LOW PRESSURE SYSTEM STARTS TO
DROP DOWN FROM THE PACIFIC NORTHWEST ON WEDNESDAY. THIS SYSTEM WILL
BRING COOLER TEMPERATURES AND WINDY CONDITIONS TO THE REGION FOR THE
LATTER HALF OF THE WEEK.
&&

.UPDATE...BAND OF HIGH CLOUDS OVER THE SOUTHERN PORTION OF THE
FORECAST AREA THIS MORNING. THESE CLOUDS LOOK TO BE THIN ENOUGH TO
JUSTIFY A MOSTLY SUNNY FORECAST AND NO UPDATES PLANNED THIS MORNING.
&&

.PREV DISCUSSION...345 AM PST MON FEB 13 2006
.SHORT TERM...A WEAK AREA OF LOW PRESSURE CONTINUES TO SPIN OFF THE
CENTRAL CALIFORNIA COAST THIS MORNING WITH SOME HIGH LEVEL
CLOUDINESS SPREADING ACROSS THE REGION. THIS SYSTEM IS FORECAST TO
MOVE INTO THE COAST THIS EVENING AND THEN ACROSS THE CWA TUESDAY
MORNING...SO OCCASIONAL HIGH CLOUDS LIKELY THROUGH EARLY TUE AFT.
UNDER THE RIDGING/WESTERLY FLOW...TEMPERATURES WILL WARM TO WELL
ABOVE NORMAL BOTH MONDAY AND TUESDAY. A MAJOR WEATHER PATTERN CHANGE
WILL BE UNDERWAY MID WEEK FEATURING STRONG LOW PRESSURE OVER HUDSON
BAY NORTH OF ONTARIO CANADA AND STRONG PACIFIC RIDGING EXPANDING AND
BUILDING NORTHWARD INTO ALASKA. AIR FLOW AROUND THE HIGH WILL FORCE
THE JET STREAM NORTHWARD WELL INTO THE POLAR REGIONS WHERE IT WILL
DRIVE A POLAR AIRMASS DOWN THE FRONT SIDE OF THE HIGH AND INTO THE
NORTHWESTERN/CENTRAL CONUS. THE FIRST IN A SERIES OF STORM SYSTEMS
ROTATING AROUND THE HUDSON BAY VORTEX WILL FEATURE THIS POLAR AIR
AND IMPACT THE NORTHERN GREAT BASIN/ROCKIES TUESDAY AND THEN THE
NORTHERN CWA WEDNESDAY. WINDS WILL BE THE MAIN CONCERN WEDNESDAY AS
THEY BECOME STRONG AND GUSTY AS SHORTWAVE ENERGY MOVES TOWARD THE
AREA. THE SYSTEM IS MAINLY DRY BUT INCREASING DYNAMICS MAY CREATE A
SHOWER WEDNESDAY AFT...MAINLY OVER CENTRAL NYE AND NORTHERN LINCOLN
COUNTIES. A LITTLE EARLY TO MAKE A CALL ON ADVISORIES OR WATCHES BUT
THE POTENTIAL EXISTS FOR WINDS TO BE STRONG ENOUGH FOR A WIND
ADVISORY OVER PORTIONS OF THE SOUTHERN CWA WEDNESDAY AFTERNOON.
THERE WILL ALSO BE FIRE WEATHER CONCERNS BUT REACHING RED FLAG
CRITERIA WILL BE TRICKY AS MOS DATA SHOWING INCREASING DWPTS AND
DECREASING TEMPS. CURRENT THINKING IS THAT ARIZONA 101 WILL BE THE
MOST LIKELY PLACE FOR A WATCH BUT WILL HOLD OFF AND TAKE A LOOK AT
THE NEXT COUPLE OF MODEL RUNS. AFTER THAT...THE NEXT SYSTEM BEGINS
TO TAKE FORM OVER THE PACIFIC NW WEDNESDAY NIGHT AND IS FORECAST TO
IMPACT THE AREA DURING THE EXTENDED PERIOD.
&&

.LONG TERM...CONFIDENCE WITH DETAILS/TIMING OF PRECIPITATION LATE IN
THE EXTENDED FOR THE AREA STILL LOW AS MODELS CONTINUE TO EXHIBIT
DIFFICULTY WITH EVOLUTION OF LONGWAVE TROUGH OVER NORTH AMERICA
DOWNSTREAM OF BLOCKING RIDGE OVER THE GULF OF ALASKA/NORTHWEST
TERRITORIES. PAST SEVERAL DAYS THE MODELS HAVE BEEN CONSISTENT IN
DEVELOPING AN UPPER LOW OVER THE PACIFIC NORTHWEST AROUND FRIDAY AS
SHORTWAVES DIG SOUTHWEST ACROSS WESTERN CANADA DUE TO STRONG
NORTHEASTERLY JET. THE FINE DETAILS/TIMING OF INDIVIDUAL SHORTWAVES
AND POTENTIALLY UPPER LOW ITSELF MOVING EASTWARD ACROSS THE AREA
NEXT WEEKEND REMAIN THE CHALLENGE. LATEST 00Z GFS/ECMWF AND GFS
ENSEMBLE MEAN KEEP MAIN LOW OVER THE NORTHWEST STATES THROUGH NEXT
SUNDAY. IF ANYTHING MODELS HAVE BEEN DELAYING MOVEMENT OF MAIN LOW
EAST ACROSS THE AREA. DUE TO UNCERTAINTY WILL MAKE NO CHANGES TO
POPS AND LEAVE SLIGHT CHANCE IN FOR LATE SATURDAY NIGHT AND SUNDAY.
WITH COLD FRONTAL PASSAGE WEDNESDAY...TEMPERATURES WILL LOWER TO
SLIGHTLY BELOW NORMAL THURSDAY THEN STAY NEAR NORMAL THROUGH
SUNDAY.
&&

.AVIATION...TAF ADEQUATELY COVERS EXPECTED WEATHER CONDITIONS AT
KLAS.
&&

.VEF WATCHES/WARNINGS/ADVISORIES...
