AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
232 PM MST WED FEB 15 2006

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT. EXTREME COLD AND
WIND TO ENTER THE REGION STARTING LATE THIS EVENING AND TONIGHT.
THIS IS A DANGEROUS STORM AS WIND CHILLS BY THURSDAY INTO THURSDAY
NIGHT COULD REACH 25 TO 35 BELOW ZERO FOR SEVERAL HOURS...MAINLY
IN WESTERN MONTANA. HIGH PRESSURE WITH THIS BITTERLY COLD AIR IN
CENTRAL CANADA WILL MOVE INTO THE GLACIER PARK REGION AROUND
MIDNIGHT THEN USHER INTO MOST OF NORTHWEST MONTANA BY THE MIDDLE
OF THE NIGHT AND INTO THE MISSOULA REGION BY DAYBREAK. SNOWFALL
WILL BE LIMITED WITH THIS SYSTEM...BUT THERE WILL BE ENOUGH SNOW
THROUGH MIDDAY THURSDAY TO CAUSE TRAVEL CONCERNS AS WIND WILL BLOW
SNOW ENOUGH TO REDUCE VISIBILITIES TO NEAR ZERO AT TIMES. THUS
BLIZZARD WARNINGS HAVE BEEN ISSUED IN THE FLATHEAD/MISSION VALLEYS
AND GLACIER NATIONAL PARK. THIS INITIAL PUSH OF BLIZZARD
CONDITIONS WILL BE BRIEF. OUTDOOR ACTIVITIES ARE DISCOURAGED IN
THESE AREAS.

THE MAIN PROBLEM WHICH WILL LAST THROUGH WESTERN MONTANA THROUGH
THURSDAY NIGHT WILL BE EXTREMELY LOW WIND CHILLS...THUS WIND CHILL
WARNINGS HAVE BEEN POSTED.

CENTRAL IDAHO WILL NOT SEE THE EXTREME COLD...BUT THE FRONTAL
BOUNDARY WILL STALL OVER CENTRAL IDAHO AND WEST CENTRAL MONTANA
ENOUGH TO PRODUCE SOME ACCUMULATING SNOW. THIS COMBINED WITH THE
WIND HAS PROMPTED A SNOW AND BLOWING SNOW ADVISORY. GREATEST SNOW
ACCUMULATIONS OF 3-7 INCHES WILL BE IN CENTRAL IDAHO.

.LONG TERM...FRIDAY THROUGH WEDNESDAY...BITTERLY COLD TEMPERATURES
EXPECTED FOR FRIDAY AND SATURDAY WITH MANY LOCATIONS EXPERIENCING
RECORD LOWS FOR THE DATE AND A HANDFUL OF SITES LIKELY SEEING
ALL-TIME FEBRUARY LOWS. COLDEST TEMPERATURES ANTICIPATED AROUND
SUNRISE SATURDAY MORNING. VALLEYS TEMPERATURES MODERATE/WARM A FEW
DEGREES EACH DAY WITH THE RELATIVELY HIGH SUN ANGLE THIS TIME OF YEAR.
MOUNTAIN AREAS SHOULD SEE A MORE RAPID WARM UP BY SUNDAY AS RELATIVELY
WARMER AIR ALOFT MOVES IN. GLOBAL MODELS IN GOOD AGREEMENT REGARDING
SUNDAY NIGHT THROUGH WEDNESDAY AS THE STRONG HIGH PRESSURE ALOFT
MOVES WESTWARD AND WE TRANSITION INTO A MOIST AND ENERGETIC
NORTHWESTLY FLOW ALOFT. THIS IS A GOOD SNOW PRODUCING PATTERN FOR
THE VALLEYS OF WESTERN MONTANA. EUROPEAN MODEL INDICATING A MORE
AMPLIFIED PATTERN AND MORE IN THE WAY OF SNOW FOR NEXT WEEK BUT
THIS A NEW SOLUTION SO WILL WAIT FOR BETTER MODEL RUN TO RUN
CONSISTENCY BEFORE RAISING PRECIPITATION CHANCES VERY MUCH. EITHER
SOLUTION LOOKS LIKE AT LEAST A WEEK OR TWO OF WINTER WEATHER FOR
THE WESTERN STATES.

&&

.AVIATION...VERY WINDY CONDITIONS ASSOCIATED WITH A STRONG COLD
FRONT IN CANADA ARE EXPECTED IN WEST CENTRAL MONTANA FROM MIDNIGHT
THROUGH THE DAY THURSDAY. BLOWING SNOW WILL REDUCE VISIBILITIES TO
LESS THAN A MILE AT TIMES AFTER MIDNIGHT...SEE APPROPRIATE TAFS
AND TWEBS.
