AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
140 AM PST SUN NOV 29 2009

.SYNOPSIS...HIGH PRESSURE WILL BUILD OVER THE REGION TODAY BRINGING
DRY WEATHER THROUGH THE END OF THE COMING WEEK. 
&&

.SHORT TERM...TODAY THROUGH TUESDAY. AN UPPER LOW IS CURRENTLY
SITUATED OVER THE AZ/CA BORDER. THIS FEATURE HAS PUSHED FAR ENOUGH
SOUTH TO RID OUR CWA OF ANY CLOUD COVER WHICH HAS ALLOWED FOR GOOD
RADIATIONAL COOLING EARLY THIS MORNING AND TEMPS ARE 10-20 DEGREES
COLDER THAN AT THIS TIME YESTERDAY. A STRONG RIDGE OF HIGH PRESSURE
WILL CONTINUE TO BUILD OVER THE GREAT BASIN TODAY...PROMOTING DRY
CONDITIONS AND A CLOUD-FREE SKY. THERE WILL STILL BE ENOUGH OF A
PRESSURE GRADIENT BETWEEN THE UPPER LOW TO OUR SOUTH AND HIGH
PRESSURE BUILDING DOWN FROM THE NORTH TO CAUSE BREEZY CONDITIONS
ACROSS CENTRAL NV LATE THIS MORNING AND AFTERNOON. HIGHS TODAY WILL 
MAINLY BE IN THE 40S.

THE UPPER RIDGE WILL REMAIN OVER THE GREAT BASIN THROUGH TUESDAY
ALLOWING FOR THE DRY CONDITIONS TO CONTINUE WITH GENERALLY CLOUD-
FREE SKIES. HIGHS BOTH MONDAY AND TUESDAY WILL BE IN THE 40S AND
LOW 50S OR ABOUT 5 DEGREES ABOVE NORMAL. 

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY. MODELS ARE IN AGREEMENT
ONLY THROUGH WEDNESDAY 12Z. MILD RIDGING IS EXPECTED TO HOLD
THROUGH THAT TIME. ON WEDNESDAY...THE ECMWF IS SHOWING A SHORT
WAVE CUTTING THROUGH THE CWA WHICH COULD BRING SOME ISOLATED
SHOWERS WHILE THE DGEX AND GFS ARE RETAINING THE RIDGE THROUGH
FRIDAY 12Z. ON FRIDAY...THE REVERSE IS THE CASE...THE ECMWF IS
HOLDING ONTO THE RIDGE PATTERN WHILE THE DGEX/GFS RUNS ARE
DROPPING A LOW IN FROM DUE NORTH. TOO MUCH DISAGREEMENT TO MAKE
MANY CHANGES THIS MORNING.
&&

.AVIATION...WINDS ARE EXPECTED TO BE LESS OF A CONCERN TODAY AS LOW 
PRESSURE CONTINUES TO MOVE WELL SOUTH THROUGH ARIZONA. GUST SHOULD 
PEAK OUT AROUND 25 MPH IN CENTRAL NEVADA. SKIES WILL BE MAINLY CLEAR 
AS RIDGING TAKES CONTROL TODAY. VFR CONDITIONS SHOULD PREVAIL FOR THE 
NEXT SEVERAL DAYS.
&&

.LKN WATCHES/WARNINGS/ADVISORIES...NONE.
