NATIONAL WEATHER SERVICE BILLINGS MT
905 AM MST SUN JAN 7 2007
.SHORT TERM...VALID FOR MON AND TUE...
WINDS ARE PICKING UP IN THE GAP FLOW AREAS WEST OF BILLINGS AS
ANOTHER WAVE MOVES INTO ALBERTA. SYSTEM IS MOVING SO FAST THAT
PRESSURE FALLS OVER ALBERTA WILL GENERATE 24 MB DIFFERENCES
BETWEEN KLWT AND KIDA BY NOON AND THIS SHOULD ALLOW WINDS TO REACH
WARNING CRITERIA IN THE FAVORED AREAS. ELSEWHERE...LOOKS LIKE
WINDS WILL PICKUP AND CLOUDS WILL INCREASE AS MOISTURE FROM THE
WAVE SPREADS INTO THE AREA. DOES LOOK FAIRLY DRY AS DEWPOINTS ARE
IN THE SINGLE DIGITS FOR MUCH OF THE AREA...SO ANY SHOWERS THAT
REACH THE AREA WILL LIKELY BE LIMITED TO TRACE ACCUMULATIONS.
CURRENT FORECAST ON TRACK AND NO UPDATES ANTICIPATED. BORSUM
.LONG TERM...VALID FOR WED...THU...FRI...SAT...SUN...
FEW CHANGES MADE TO THE EXTENDED FORECAST TODAY AS MODELS
CONTINUE TO BE IN GOOD AGREEMENT FOR THE MOST PART.
WEDNESDAY STILL A VERY TRICKY DAY IN TERMS OF TEMPERATURES. THE
TIMING OF THE ARCTIC COLD FRONT IS STILL IN QUESTION. THE GFS
CONTINUES TO BE FASTER WITH THE FRONT THAN THE ECMWF. DID LOWER
TEMPERATURES A DEGREE OR TWO BUT NOT CONFIDENT ENOUGH TO DO
ANYTHING ELSE WITH IT. DID RAISE POPS ON WEDNESDAY ACROSS MUCH OF
THE AREA WITH SNOW LOOKING LIKE A GOOD POSSIBILITY. UPPER LEVEL
TROUGH STAYS OVER THE AREA THROUGH NEXT WEEKEND AND HAVE KEPT
SLIGHT CHANCE POPS FOR THAT ENTIRE PERIOD.
DID LOWER HIGH TEMPERATURES ON THURSDAY AND FRIDAY A FEW DEGREES
CLOSER TO GUIDANCE. LOWERED LOW TEMPERATURES DURING THIS PERIOD
QUITE A BIT AS 850 TEMPERATURES OF -25 DEGREES CELSIUS SHOULD
DROP TEMPERATURES WELL BELOW ZERO DURING THE NIGHT. LOW
TEMPERATURES OF -5 TO -15 DEGREES FAHRENHEIT ARE NOT OUT OF THE
QUESTION THURSDAY AND FRIDAY NIGHT. SOLUM
&&
.AVIATION...
SKIES WILL BECOME MOSTLY CLOUDY DURING THE DAY AS ANOTHER
DISTURBANCE APPROACHES THE FORECAST AREA. SNOW SHOWERS WILL BE
LIKELY OVER THE BEARTOOTH/ABSAROKA RANGE WITH MOUNTAIN
OBSCURATIONS LIKELY ALONG WITH MVFR CONDITIONS AT TIMES. A SLIGHT
CHANCE FOR A RAIN OR SNOW SHOWER WILL EXIST OVER THE PLAINS WITH
OCCASIONAL MVFR CONDITIONS WITH ANY SHOWER. IN ADDITION...STRONG
WINDS WILL DEVELOP ACROSS THE WESTERN ROUTES THIS AFTERNOON.
GUSTS UP TO 85 MPH WILL BE POSSIBLE IN THE LIVINGSTON AREA AND
ALONG THE FOOTHILLS OF THE ABSAROKA AND BEARTOOTH MOUNTAINS WITH
GUSTS TO 75 MPH ELSEWHERE ACROSS THE WEST. HOOLEY
