AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
259 AM MST WED JAN 11 2006

.SHORT TERM...THE MOIST PACIFIC WEATHER SYSTEM CONTINUES OVER
NORTH CENTRAL IDAHO AND WESTERN MONTANA. WITH THE VERY MILD
TEMPERATURES...MOST VALLEY LOCATIONS HAVE RECEIVED RAIN WHILE THE
MOUNTAINS HAVE GOTTEN SIGNIFICANT SNOWFALL TOTALS. A COLD FRONT
WILL PUSH ACROSS THE REGION EARLY THIS AFTERNOON. WHEN THIS
HAPPENS THE STEADY PRECIPITATION WILL CHANGE TO SHOWERS AND THE
VALLEY RAIN WILL MIX WITH SNOW AND AT MANY LOCATIONS CHANGE OVER
TO ALL SNOW. A WEST UPPER LEVEL FLOW WILL CONTINUE INTO THE
REGION FROM THE PACIFIC TONIGHT AND THURSDAY WITH A COLDER AND
UNSTABLE AIRMASS OVER WESTERN MONTANA AND NORTH CENTRAL IDAHO.
THEREFORE...WILL KEEP A CHANCE OF LIGHT SNOW AND RAIN SHOWERS IN
THE FORECAST THROUGH THURSDAY NIGHT.

.LONG TERM...FRIDAY THROUGH WEDNESDAY. THE TREND FOR ACTIVE AND
UNSETTLED WEATHER CONTINUES INTO NEXT WEEK. FRIDAY MORNING A
SHARP UPPER LEVEL TROUGH OFF THE PACIFIC COAST WILL PLACE THE
NORTHERN ROCKIES UNDER SOUTHWESTERLY FLOW. THIS FLOW PATTERN WILL
USHER IN WARM PACIFIC MOISTURE WHICH WILL LEAD TO A DECENT WARM
OVER-RUNNING PRECIPITATION EVENT ON FRIDAY AND SATURDAY. IT APPEARS
AS THOUGH ENOUGH COOLER AIR WILL SETTLE WITHIN THE LOWEST VALLEY
LOCATION ACROSS NORTHWESTERN MONTANA PRIOR TO THE MOISTURES
ARRIVAL. THIS WILL CREATE THE POTENTIAL MORNING FREEZING RAIN
WITHIN THESE VALLEYS. BY SATURDAY EVENING A SURFACE COLD FRONT
WILL MOVE THROUGH WESTERN MONTANA AND CENTRAL IDAHO. THIS WILL
ONCE AGAIN DROP THE SNOW LEVELS TO NEAR VALLEY FLOORS BY LATE
SUNDAY AS SCATTERED SNOW SHOWERS PERSIST ACROSS THE AREA.

MONDAY A WEAK UPPER LEVEL RIDGE BEGINS TO FORM AND AN ASSOCIATED
SURFACE HIGH PRESSURE SYSTEM BUILDS OVER THE INTER-MOUNTAIN WEST.
THIS WILL ALLOW FOR SOME ADDITIONAL COOLING IN THE MOUNTAINS
HOWEVER VALLEY INVERSIONS SHOULD REMAIN IN PLACE KEEPING
TEMPERATURES IN THESE LOCATIONS MODERATED. ANOTHER WARM PACIFIC SYSTEM
WILL APPROACH THE NORTHERN ROCKIES ON TUESDAY BRINING MOUNTAIN
SNOW AND A MIX OF RAIN AND SNOW TO THE VALLEYS. THERE COULD BE
ANOTHER CHANCE OF FREEZING RAIN OVERNIGHT MONDAY FOR NORTHWESTERN
MONTANA VALLEYS...HOWEVER IT IS TOO SOON TO TELL FOR SURE. THE
REMAINDER OF THE WEEK LOOKS UNSETTLED AS A LARGE BROAD SCALE UPPER
LEVEL TROUGH BEGINS TO FORMS ACROSS THE UNITED STATES AND HINTS OF
MORE SEASONAL WINTER TEMPERATURES SHOW THEMSELVES.

&&

.AVIATION...THE MOIST PACIFIC WEATHER SYSTEM WILL CONTINUE TO
IMPACT WESTERN MONTANA AND NORTH CENTRAL IDAHO THROUGH THIS
AFTERNOON. RAIN IN THE VALLEYS AND SNOW OVER THE MOUNTAINS ALONG
WITH GUSTY SOUTHWEST WINDS WILL PERSIST INTO EARLY AFTERNOON.
MOUNTAINS AND PASSES WILL BE OBSCURED PLEASE SEE APPROPRIATE TAFS
