AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
245 PM MST THU DEC 30 2010

...VERY COLD TEMPERATURES ACROSS WESTERN MONTANA AND NORTH CENTRAL
IDAHO FOR TONIGHT AND FRIDAY NIGHT...

.DISCUSSION...

LATE THIS AFTERNOON THROUGH SATURDAY...EAST AND NORTHEASTERLY WINDS
ACROSS WESTERN MONTANA WILL SLOWLY DIMINISH DURING THE REMAINDER OF
TODAY...WITH THE WINDCHILL IMPACT DIMINISHING AS WELL. ARCTIC AIR
WILL SETTLE ACROSS VALLEY LOCATIONS OVERNIGHT...WITH SCATTERED TO
BROKEN MID LEVEL CLOUD COVER ALLOWING TEMPERATURES TO PLUMMET. MANY
VALLEY LOCATIONS NEAR THE CONTINENTAL DIVIDE MAY EXPERIENCE
TEMPERATURES AS LOW AS MINUS 30 DEGREES BY FRIDAY MORNING. LIGHT
NORTHERLY FLOW AND A RELATIVELY WARM FLATHEAD LAKE...SOME LAKE
EFFECT FLURRIES AND LIGHT SNOW ARE POSSIBLE ALONG THE SOUTHERN SHORE
OF THE LAKE...INCLUDING POLSON DURING THE OVERNIGHT TONIGHT.
CONSIDERING THAT HIGH PRESSURE WILL BE PRESENT OVER THE NORTHERN
ROCKIES ON FRIDAY...TEMPERATURES WILL STRUGGLE TO REACH THE SINGLE
DIGITS ABOVE ZERO DURING FRIDAY AFTERNOON. FRIDAY NIGHT THROUGH
SATURDAY MORNING WILL ALSO BE VERY COLD FOR WESTERN MONTANA...WHILE
IT WILL LIKELY THE COLDEST PERIOD FOR NORTH CENTRAL IDAHO DURING THE
NEAR TERM. SATURDAY AFTERNOON TEMPERATURES ARE EXPECTED TO WARM
SLIGHTLY OVER THOSE ON FRIDAY.

SATURDAY NIGHT THERE WILL BE A NORTHWEST FLOW OVER WESTERN MONTANA
AND NORTH CENTRAL IDAHO. A DISTURBANCE WILL MOVE ACROSS CENTRAL
MONTANA SUNDAY AFTERNOON AND NIGHT WHICH COULD BRING A FEW SHOWERS
TO WESTERN MONTANA...ESPECIALLY TO NORTHWEST MONTANA AND ALONG THE
CONTINENTAL DIVIDE. MONDAY AND TUESDAY WILL SEE A WEAK RIDGE OF
HIGH PRESSURE MOVE OVER IDAHO...BRINGING LESS CLOUDS AND
DECREASING CHANCE OF PRECIPITATION. BY THURSDAY ANOTHER PACIFIC
WEATHER SYSTEM WILL BE MOVING TOWARD WESTERN MONTANA...AND
SPREADING SOME SNOW IN FROM THE WEST.

&&

.AVIATION...FLYING CONDITIONS WILL IMPROVE DURING THE NEXT 24
HOURS...AS THE PREVIOUS STORM SYSTEM MOVES EAST OF THE NORTHERN
ROCKIES. SNOW WILL BE MOSTLY TERRAIN BASED AND SLOWLY DIMINISH
THROUGHOUT THE REMAINDER OF TODAY. MUCH OF THE VISIBILITY AND LOW
CEILINGS CONCERNS WILL BE DUE TO SNOW AND MOST CONCENTRATED ALONG
THE CONTINENTAL DIVIDE. THE AMOUNT OBSCURED TERRAIN WILL DECREASE
DURING THIS TIME ALSO. NORTHEASTERLY WINDS AT KGPI WILL REMAIN
FAIRLY CONSTANT THROUGH THIS EVENING AND DIMINISH SIGNIFICANTLY
AFTER SUNSET.
