AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
310 AM MST MON DEC 3 2007

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...
NO PRECIPITATION TO MENTION IN THE PERIOD THROUGH TUESDAY
NIGHT...BUT WINDS WILL CONTINUE TO BE THE MAIN CONCERN WITH THIS
FORECAST PACKAGE. HAVE ALREADY VERIFIED CURRENT WARNING FOR PLATTE
COUNTY WITH BORDEAUX EXCEEDING CRITERIA FOR BOTH SUSTAINED WINDS
AND GUSTS SINCE MIDNIGHT. CARBON AND ALBANY COUNTY LOCATIONS ARE
ALSO NEARING WARNING CRITERIA EARLY THIS MORNING. THE SURFACE
PRESSURE GRADIENT CONTINUES TO SHOW SUPPORT FOR HIGH WINDS TO
CONTINUE OVERNIGHT TONIGHT...AND HAVE DECIDED TO EXTEND THE
EXISTING HIGH WIND WARNINGS OUT UNTIL 12Z TUESDAY. ADDITIONAL
SUPPORT FOR EXTENDING THE WARNINGS COMES FROM THE BUFKIT
SOUNDINGS AND MODEL TIME-HEIGHT PLOTS SHOWING 700 MB WINDS IN
EXCESS OF 50 KNOTS AND SUBSIDENCE FROM THE UPPER LEVEL RIDGE JUST
OFF TO THE WEST OF THE FORECAST AREA. THE SURFACE PRESSURE
GRADIENT SHOULD BEGIN TO DECREASE DURING THE DAY TUESDAY ALLOWING
SURFACE WINDS TO DECREASE SLIGHTLY. STRONG AND GUSTY WINDS WILL
STILL BE PRESENT...BUT FROM THE NORTHWEST AS THE GRADIENT ADJUSTS
TO THE SURFACE LOW MOVING QUICKLY FROM NORTHEAST MONTANA TO
WESTERN IOWA BY LATE IN THE DAY TUESDAY. WIND SPEEDS IN THE
NEBRASKA PANHANDLE SHOULD APPROACH THE 30 MPH SUSTAINED WIND
CRITERIA FOR ADVISORIES THERE BUT WILL HOLD OFF AND NOT ISSUE
ANYTHING FOR THE PANHANDLE TO LET THE DAY SHIFT HAVE ANOTHER LOOK.

WITH THE WINDY CONDITIONS IN PLACE...TEMPERATURES TODAY WILL BE 10
TO 15 DEGREES ABOVE NORMAL. AFTER A WARM START TO TUESDAY...HIGHS
ARE EXPECTED TO BE EVEN SLIGHTLY WARMER REACHING 15 TO 20 DEGREES
ABOVE NORMAL WITH A BIT MORE SUNSHINE PRESENT AHEAD OF THE WEAK
COLD FRONTAL PASSAGE LATE IN THE DAY. FAVORING THE GFS TIMING FOR
THE FRONT AND TUESDAY HIGHS...BUT THE LATEST WRF-NMM GUIDANCE IS
SUGGESTING TUESDAY TEMPERATURES WILL BE NEARLY EQUAL TO THOSE
EXPECTED LATER TODAY. CARPENTER

.LONG TERM...WEDNESDAY THROUGH SUNDAY...
NW FLOW WILL BE ALOFT WED AS AN UPPER TROUGH MOVES SE ACROSS THE
AREA WITH THE TROUGH AXIS EAST OF THE AREA BY 12Z THUR.  WINDY
CONDITIONS WILL PERSIST WED MORNING WITH A CHANCE OF SNOW ACROSS THE
AREA WED NIGHT AS MOISTURE INCREASES WITH THE PASSAGE OF THE UPPER
TROUGH.  FOR THUR...NW FLOW WILL CONTINUE ALOFT WITH A SERIES OF
DISTURBANCES MOVING ACROSS THE AREA.  MOISTURE WILL BE DECREASING
OVER THE AREA AS THE DAY PROGRESSES AND DOWNSLOPE WINDS OCCUR AT THE
SURFACE.  HOWEVER...WILL LEAVE A CHANCE OF SNOW IN THE FORECAST FOR
THE MOUNTAINS DUE TO THE NW FLOW AND LOW LEVEL MOISTURE OVER THIS
AREA.  FOR FRI...AN UPPER RIDGE WILL MOVE RAPIDLY ACROSS THE AREA.
BRISK CONDITIONS WILL DEVELOP IN THE AFTERNOON AS 700 MB AND SURFACE
GRADIENTS INCREASE.  A CHANCE OF SNOW SHOWERS WILL CONTINUE IN THE
MOUNTAINS WITH LOW LEVEL MOISTURE AND OROGRAPHIC LIFT.  ON SAT...THE
FLOW ALOFT WILL BECOME SW AS AN UPPER TROUGH MOVES INTO THE SW U.S.
AND AN UPPER LOW FORMS OVER SRN CA.  A SERIES OF DISTURBANCES MOVING
ACROSS THE AREA WILL KEEP A CHANCE OF SNOW SHOWERS IN THE
MOUNTAINS.  FOR SUN...SW FLOW WILL CONT AS THE UPPER TROUGH MOVES
ACROSS THE SOUTHERN ROCKIES.  UPSLOPE FLOW NEAR THE SOUTHERN
MOUNTAINS WILL KEEP THE THREAT OF SNOW SHOWERS IN AND NEAR THE
MOUNTAINS.  HIGH TEMPERATURES WILL BE FROM 5 TO 8 DEGREES ABOVE
NORMAL FOR WED...AROUND NORMAL FOR THUR AND FRI...AND 5 TO 8 DEGREES
ABOVE NORMAL FOR SAT AND SUN.
