AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
ISSUED BY NATIONAL WEATHER SERVICE FLAGSTAFF AZ
925 AM PST WED NOV 10 2010

.SYNOPSIS...A LOW PRESSURE SYSTEM MOVING THROUGH THE GREAT BASIN
TODAY AND TONIGHT WILL KEEP TEMPERATURES BELOW NORMAL AND WILL ALSO
BRING A CHANCE OF RAIN AND SNOW SHOWERS MAINLY TO LINCOLN COUNTY.
BREEZY NORTH WINDS WILL DEVELOP TONIGHT AND VETERANS DAY AS THE LOW
PRESSURE SYSTEM MOVES INTO THE FOUR CORNERS REGION. A COOL NORTHWEST
FLOW WILL PERSIST OVER THE REGION THROUGH THE COMING WEEKEND.

&&

.SHORT TERM...AN UPPER LEVEL TROUGH WAS CENTERED OVER NV THIS
MORNING WITH CLOUD COVER WITH RAIN AND SNOW SHOWERS AFFECTING
NORTHERN LINCOLN COUNTY AND CENTRAL NYE COUNTY. SURFACE OBSERVATIONS
IN THE AREA AND RADAR INDICATE ONLY LIGHT AMOUNTS SO FAR DUE TO
LIMITED MOISTURE AT THE SOUTHERN END OF THIS SYSTEM. EXPECT SHOWERS
TO SPREAD SLIGHTLY FARTHER SOUTHWARD THIS TODAY AND INTO THIS
EVENING BEFORE TAPERING OFF OVERNIGHT AS THE TROUGH MOVES
SOUTHEASTWARD TOWARD THE FOUR CORNERS AREA. MODELS CONTINUE TO
INDICATE NEGATIVE LIFTED INDICES IN THE NORTHEASTERN LAS VEGAS
FORECAST AREA...SO A SLIGHT CHANCE OF THUNDERSTORMS ACCOMPANYING
SHOWERS STILL LOOKS GOOD. THE CURRENT FORECAST FOR TODAY WITH DRY
CONDITIONS NEAR AND SOUTH OF LAS VEGAS RANGING TO A CHANCE OF LIGHT
SNOW ACCUMULATIONS LESS THAN 2 INCHES OVER NORTHERN LINCOLN COUNTY
LOOKS GOOD AND NO UPDATES ARE PLANNED THIS MORNING.

A DRY BUT COOL NORTHWEST FLOW WILL BE OVER THE AREA THURSDAY THROUGH
FRIDAY NIGHT. NORTHERLY WINDS WILL PICK UP BEHIND THE TROUGH TONIGHT
AND WILL BE LOCALLY GUSTY THROUGH THURSDAY. OVERALL IT LOOKS LIKE
WINDS WILL STAY BELOW ADVISORY CRITERIA BUT WE WILL HAVE TO WATCH
FOR POSSIBLE LAKE WIND ADVISORY LEVEL WINDS DOWN THE COLORADO RIVER
VALLEY ON THURSDAY. WITH THE TROUGH MOVING THROUGH TODAY AND THE
NORTHERLY WINDS BEHIND IT...TEMPERATURES WILL REMAIN BELOW NORMAL
THROUGH FRIDAY.

.LONG TERM...SATURDAY THROUGH TUESDAY...NORTHWEST FLOW TO CONTINUE
AS A STRONG RIDGE WILL BE IN THE EASTERN PACIFIC AND A DEEP TROUGH
OVER THE CENTRAL CONUS. STILL LOOK FOR A MINOR TROUGH TO PASS
THROUGH THE AREA SATURDAY. WITH THE LATEST MODEL RUNS THE MOISTURE
LOOKS EVEN SKIMPIER IN THE NORTHEAST PART OF THE FORECAST AREA HAVE
LOWERED POPS MORE THERE. THE MAIN IMPACT WILL BE INCREASED NORTH
WINDS IN THE AREA AS HIGH PRESSURE BEHIND IT TIGHTENS THE PRESSURE
GRADIENT SATURDAY AND SUNDAY. THE NEXT WAVE IN THE NORTHWEST FLOW IS
LOOKING WEAKER IN THE ECMWF COMPARED TO LAST NIGHTS RUN WHILE THE
GFS CONTINUES TO HAVE IT WEAK AND FURTHER EAST. FOR NOW WILL NOT
MAKE ANY CHANGES TO THE FORECAST FOR SUNDAY WHEN IT PASSES. WILL
KEEP THE VERY LOW POPS IN NORTHEAST LINCOLN COUNTY AND NORTH WINDS
CONTINUING OVER THE AREA AND A BIT REFRESHED IN STRENGTH SUNDAY AND
EARLY MONDAY. THE STRONGEST WINDS WILL BE IN THE COLORADO RIVER
VALLEY AND THE MOUNTAINS OF INYO AND CLARK COUNTIES. NOT EXPECTING
ANY ADVISORY LEVEL WINDS FOR THEN. FOR THE REST OF THE EXTENDED
STARTING MONDAY EXPECT CONTINUED NORTHWEST FLOW WITH NO SIGNIFICANT
WEATHER OF NOTE.

&&

.AVIATION...FOR MCCARRAN...LIGHT AND VARIABLE WINDS WILL CONTINUE
THIS MORNING INTO THE EARLY AFTERNOON. IN THE 01-04Z TIME FRAME
EXPECT A WEAK FRONT TO PASS THROUGH THAT WILL SWITCH THE WINDS TO
THE NORTHWEST WITH WIND SPEEDS OF 10 TO 20 KNOTS THROUGH THURSDAY
MORNING. HIGH LEVEL CIRRUS WILL BE INCREASING IN THE AFTERNOON
BECOMING CEILINGS THIS EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...NORTHWEST WINDS AROUND 10-25 MPH WILL DEVELOP THIS
AFTERNOON OVER ESMERALDA AND INYO COUNTIES AS THE FRONT PUSHES
SOUTHWARD ACROSS THE AREA. EXPECT WESTERLY WINDS...20 TO 30 KTS...TO
CONTINUE OVER SAN BERNARDINO COUNTY THROUGH THE AFTERNOON. THE COLD
FRONT WILL PUSH THROUGH THE REST OF THE REGION THROUGH WEDNESDAY
NIGHT BRINGING GUSTY NORTH WINDS OF 15-25 KNOTS. MOSTLY CIRRUS LEVEL
CLOUDS ARE EXPECTED TO SPREAD OVER THE AREA FORM THE NORTH THIS
AFTERNOON AND EVENING.
