SOUTHWEST AND NORTH CENTRAL MONTANA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
230 AM MST SAT DEC 8 2001
.SHORT TERM...STRONG WINDS HAVE INCREASED ALONG THE ROCKY MOUNTAIN
FRONT THIS MORNING WITH GUSTS JUST BELOW HIGH WIND WARNING CRITERIA.
WINDS DO DIMINISH LATER THIS MORNING AND THEN PICK-UP AGAIN THIS
AFTERNOON. MODELS ARE SHOWING A WEAKER PRESSURE GRADIENT PATTERN AND
WEAKER 850MB WINDS FOR THIS AFTERNOON. HOWEVER...700MB WINDS ARE
STRONGER AND ARE OUT OF A MORE FAVORABLE DIRECTION THE WEST-
SOUTHWEST. BELIEVE THAT 850MB WINDS WOULD BE STRONGER IF WE WERE ABLE
TO MIX UP TO THE 700MB LEVEL...THEREFORE PLAN ON LETTING THE WATCH
EXPIRE AND NOT UPGRADE TO A WARNING.
WARM CONDITIONS WILL PERSIST TODAY AHEAD OF THE NEXT TROUGH THAT
MOVES THROUGH THE AREA SUNDAY. WILL KEEP THE SLIGHT CHANCE OF SNOW
SHOWERS IN THE FORECAST FOR SUNDAY. ATMOSPHERE LOOKS TO BE A LITTLE
UNSTABLE SUNDAY AFTERNOON BEHIND THE COLD FRONT. ALSO THE MESOETA IS
SHOWING A LITTLE QPF OVER THE EASTERN ZONES. SURFACE HIGH PRESSURE
SETS IN SUNDAY NIGHT OVER THE SOUTHWEST BRINGING SOME COLD OVERNIGHT
LOWS. THEN FOR MONDAY A WEAKER TROUGH MOVES ACROSS THE CWA RESULTING
IN A CHANCE OF SNOW FOR THE MOUNTAINS. MEIER
.EXTENDED...BROAD TROUGH OVER REGION TUESDAY GIVES WAY TO CHINOOK
WINDS WEDNESDAY AND THURSDAY. VIGOROUS WARM FRONT CROSSES THE AREA
LATE WEDNESDAY/EARLY THURSDAY WITH ANOTHER HIGH WIND EVENT POSSIBLE.
MRF PUTS TEMPERATURES INTO THE 40S...WITH ECMWF NOT QUITE AS WARM.
SYSTEM TO WATCH IS ON FRIDAY...WHEN MRF/ECMWF PUT A SURFACE LOW OVER
MONTANA. WILL LEAVE OUT MENTION OF PRECIP FOR NOW...BUT IF LOW SETS
UP FURTHER SOUTH SNOW WOULD BE INEVITABLE. WILL NOT TINKER WITH
PREVIOUS PACKAGE EXCEPT TO REFLECT LIKELIHOOD OF WARMER TEMPS IN SOME
ZONES FOR WEDNESDAY AND THURSDAY. POMEROY
