SATURDAY WITH GUSTY SW WINDS SPREADING EAST ACROSS MUCH OF NORTH
CENTRAL MT WITH GUSTS TO 50 MPH POSSIBLE ACROSS PORTIONS OF GLACIER
COUNTY BY SATURDAY AFTERNOON. WINDS AND WARMING ALOFT WILL
SIGNIFICANTLY MODERATE THE AIRMASS ACROSS THE FORECAST AREA WITH
MOST LOCATIONS SEEING MAX TEMPS IN THE TEENS AND TWENTIES BY
SATURDAY AFTERNOON. THERE WILL BE A PERIOD TONIGHT WHEN TEMPS ARE
STILL COLD AS WINDS DEVELOP FOR VERY LOW WIND CHILLS ACROSS MUCH OF
NORTH CENTRAL MT AND WILL HAVE A WIND CHILL ADVISORY FROM MIDNIGHT
TONIGHT THROUGH SATURDAY MORNING. CONCERN THEN SHIFTS TO BLOWING
SNOW POTENTIAL AS WINDS INCREASE FURTHER BY SATURDAY AFTERNOON WITH
SIGNIFICANT BLOWING AND DRIFTING EXPECTED...ESPECIALLY IN THE
GLACIER COUNTY AREA AND WILL HIGHLIGHT THIS WITH A WINTER WEATHER
ADVISORY FOR BLOWING SNOW FOR MOST OF NORTH CENTRAL MT TOMORROW.
WINDS DECREASE BUT WILL REMAIN BREEZY SATURDAY NIGHT INTO SUNDAY
WITH TEMPERATURES CONTINUING TO WARM BUT REMAINING BELOW SEASONAL
AVERAGES. HOENISCH

SUNDAY NIGHT THROUGH FRIDAY NIGHT...MODELS ARE IN FAIRLY GOOD
AGREEMENT TONIGHT FOR THIS PERIOD. A MOIST WESTERLY FLOW ALOFT WILL
REMAIN OVER THE TFX CWA SUNDAY NIGHT THROUGH MONDAY NIGHT. A COLD
FRONT WILL DEVELOP ALONG THE CANADIAN BORDER SUNDAY NIGHT...KEEPING
THE BEST CHANCE FOR PRECIPITATION IN THE WESTERN MOUNTAINS AND ALONG
THE FRONTAL BOUNDARY. TEMPERATURES WILL MOSTLY REMAIN NEAR SEASONAL
AVERAGES...EXCEPT FOR 5 TO 10 DEGREE BELOW NORMAL LOWS ALONG THE
FRONTAL BOUNDARY. THIS COLD FRONT WILL THEN MOVE SOUTH OVER THE
PLAINS OF NORTH CENTRAL AND CENTRAL MONTANA MONDAY AND MONDAY
NIGHT...SHIFTING SURFACE WINDS MORE NORTHERLY AND UPSLOPE. THIS WILL
USHER IN MUCH BELOW NORMAL TEMPERATURES FOR THIS AREA BY MONDAY
NIGHT AND TUESDAY...ALONG WITH AN INCREASED CHANCE OF SNOW.
HOWEVER...THE COLD AIR WILL REMAIN EAST OF THE ROCKIES...KEEPING THE
VALLEYS OF SOUTHWEST MONTANA NEAR NORMAL TEMPERATURE-WISE. THE MOIST
WESTERLY FLOW ALOFT WILL LIKELY KEEP SNOW IN THE WESTERN MOUNTAINS
AS WELL DURING THIS TIME...AND THIS SITUATION WILL NEED TO BE
MONITORED FOR POSSIBLE WIND AND/OR WINTER WEATHER HIGHLIGHTS. THE
CHANCE FOR SNOW WILL DECREASE OVERALL TUESDAY AND TUESDAY NIGHT AS
AN UPPER LEVEL RIDGE OF HIGH PRESSURE BUILDS INTO THE AREA. THIS
WILL ALSO MODERATE TEMPERATURES CLOSER TO NORMAL BY WEDNESDAY. AN
UPPER LEVEL TROUGH OF LOW PRESSURE WILL THEN DEEPEN OVER THE PACIFIC
COAST STATES WEDNESDAY NIGHT INTO THURSDAY...FOR AN INCREASING
CHANCE OF SNOW AGAIN OVER THE MOUNTAINS OF WESTERN AND CENTRAL
MONTANA. HOWEVER...TEMPERATURES WILL CONTINUE TO WARM TO
NEAR/SLIGHTLY ABOVE NORMAL ACROSS THE AREA THROUGH THURSDAY. THE
UPPER LEVEL TROUGH WILL THEN MOVE INTO THE AREA THURSDAY NIGHT
THROUGH FRIDAY NIGHT...BRINGING ANOTHER CANADIAN COLD FRONT INTO THE
AREA WITH A CONTINUED CHANCE OF SNOW. TEMPERATURES EAST OF THE
ROCKIES WILL FALL SLIGHTLY BELOW NORMAL AGAIN...WHILE TEMPERATURES
REMAIN NEAR NORMAL ACROSS SOUTHWEST MONTANA.  COULSTON

ADJACENT PLAINS. WINDS WILL BECOME VERY STRONG AND GUSTY BY MID
MORNING...ESPECIALLY ALONG THE LEE SLOPES OF THE ROCKIES. THIS WILL
CAUSE AREAS OF BLOWING SNOW WITH RESTRICTED VISIBILITIES. VFR CONDS
