AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
408 AM MST TUE NOV 16 2010
...STRONG POSSIBLY DAMAGING WINDS EXPECTED THIS MORNING...
...ACCUMULATING MOUNTAIN SNOWS OVER THE PASSES THIS MORNING...
.DISCUSSION...SEVERAL HAZARDOUS WEATHER EVENTS ARE ON-GOING OR
EXPECTED THIS MORNING DUE TO AN INTENSE LOW PRESSURE SYSTEM ENTERING
THE NORTHERN ROCKIES.
WIND...STRONG WINDS WILL BE THE IMMEDIATE HAZARD EARLY THIS
MORNING FOR THE MORNING COMMUTE. A LINE OF THUNDERSTORMS HAS
DEVELOPED AND IS CURRENTLY MOVING THROUGH CAMAS PRAIRIE IN NORTH
CENTRAL IDAHO. THIS LINE WILL MOVE THROUGH CENTRAL IDAHO THROUGH 4
AM MDT THEN SWEEP ACROSS WESTERN AND SOUTHWEST MONTANA FROM 5 TO 9
AM MDT. EXPECT STRONG SOUTHERLY WINDS AHEAD OF THE FRONT THEN
SHIFTING TO THE WEST/NORTHWEST BEHIND IT. WINDS ALONG THIS FRONT
ARE VERY STRONG. WIDESPREAD WIND GUSTS OF 40-50 MPH WITH LOCAL
GUSTS TO NEAR 60 MPH ARE EXPECTED ALONG THE FRONT. STRONG WINDS
ARE ANTICIPATED BEHIND THE FRONT TODAY. WIND IMPACTS THE REST OF
THE MORNING WILL BE IN THE BITTERROOT/MISSOULA VALLEYS AND THE
I-90 CORRIDOR FROM BUTTE TO DEER LODGE. PLEASE SEE GTFNPWMSO FOR
DETAILS.
MOUNTAIN SNOW WILL ALSO BE A MAJOR IMPACT THIS MORNING AND
CONTINUING THROUGH THE DAY. WIDESPREAD SNOWS ABOVE 6000 FEET
STARTED LAST EVENING. SNOW LEVELS WILL LOWER THIS MORNING TO PASS
LEVELS WHERE SEVERAL INCHES OF SNOW ARE EXPECTED BY MID MORNING.
STRONG WINDS WITH THIS SYSTEM WILL REDUCE VISIBILITIES AT TIMES
DUE TO BLOWING SNOW. PLEASE SEE GTFWSWMSO FOR DETAILS ON ALL
WINTER HIGHLIGHTS. VALLEYS WILL EXPERIENCE ALL RAIN THIS MORNING.
HOWEVER...SNOW LEVELS WILL LOWER TO THE VALLEY FLOOR DURING THE
AFTERNOON...BUT THE BULK OF PRECIPITATION WILL HAVE MOVED EAST OF
THE AREA LEAVING BEHIND SNOW SHOWERS WITH LITTLE OR NO
ACCUMULATIONS.
MEDIUM RANGE MODELS HAVE COME INTO BETTER AGREEMENT FOR THE
UPCOMING COLD WEATHER PATTERN INCLUDING A MOIST JET AND COLD FRONT
BEGINNING LATE WEDNESDAY. THE HIGH TERRAIN AND NORTHWEST MONTANA
WILL BE THE FIRST TO SEE IMPACTS FROM SNOW DURING THIS SYSTEM.
ASSOCIATED SURFACE COLD FRONT WITH THIS SYSTEM WILL MOVE SOUTHWARD
THROUGH THE REGION ON THURSDAY AND QUICKLY DROP SNOW
LEVELS...WHICH COULD ALLOW FOR SNOW ACCUMULATIONS AT ALL
ELEVATIONS BY LATE THURSDAY. IT STILL APPEARS THAT THE FRONT COULD
STALL OVER EAST CENTRAL IDAHO AND SOUTHWEST MONTANA ON FRIDAY AND
COULD LEAD TO A WIDE BAND OF PERSISTENT SNOW. THE MAIN TROUGH
ASSOCIATED WITH THE JET AND COLD FRONT WILL SAG SOUTHWARD ON
SATURDAY. COLD AIR SLOSHING ALONG THE CONTINENTAL DIVIDE WILL
EVENTUALLY WORK THROUGH INTO THE LOWER VALLEYS BRINGING MUCH
COOLER TEMPERATURES FOR THE COMING WEEKEND. THE FINER DETAILS OF
TIMING THIS FEATURE ARE STILL LACKING...BUT CONFIDENCE IN MODEL
GUIDANCE HAS FURTHER INCREASED IN A MUCH COOLER TEMPERATURE
FORECAST FOR THE WEEKEND AND EARLY NEXT WEEK.
&&
.AVIATION...A STRONG PACIFIC WEATHER SYSTEM WILL CONTINUE TO IMPACT
WESTERN MONTANA AND NORTH CENTRAL IDAHO TODAY AND INTO THIS EVENING.
STRONG SOUTHWEST WINDS WILL OCCUR IN MANY AREAS...ESPECIALLY FROM
THE BITTERROOT MOUNTAINS EASTWARD TO THE CONTINENTAL DIVIDE BEFORE
TRANSITIONING TO THE WEST MID TO LATE MORNING. LOCALLY STRONG MOUNTAIN
INDUCED WAVES/WIND STORMS MAY DEVELOP WITH SIGNIFICANT TURBULENCE
POSSIBLE...ESPECIALLY IN THE VICINITY OF KBTM AND KMSO. TERRAIN
OBSCURATIONS WILL BE WIDESPREAD TUESDAY MORNING AS PRECIPITATION
QUICKLY DEVELOPS ACROSS THE AREA. COOLER AIR ALOFT WILL CONTINUE
TO LOWER SNOW LEVELS....ALLOWING FOR PRECIPITATION TO TRANSITION
TO A SNOW-RAIN MIX LATER IN THE DAY.
