AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
834 AM MST FRI DEC 14 2007

.DISCUSSION...AN AREA OF LIGHT SNOW IS IMPACTING PORTIONS OF THE
NORTHERN CLEARWATERS EASTWARD ACROSS THE NORTHERN BITTERROOTS AND
SAPPHIRES THIS MORNING...WHICH IS VERY SIMILAR TO THE THURSDAY SYSTEM.
FORECASTS HAVE BEEN UPDATED TO REFLECT SNOW MANY OF THESE AREAS.
HOWEVER...AMOUNTS SHOULD BE GENERALLY LIGHT. EARLIER...WE EXPECTED
DRYER AIR TO QUICKLY MOVE OVER THE REGION THIS AFTERNOON.
HOWEVER...THERE APPEARS TO BE SIGNIFICANTLY MORE MOISTURE
IMMEDIATELY UPSTREAM THAN THE MODELS INDICATE. AS SUCH...WE MAY
ALSO UPDATE FOR LESS SUN AND SOME LINGER FLURRIES THIS AFTERNOON.

&&

.AVIATION...A WEATHER DISTURBANCE WILL CONTINUE TO PRODUCE TERRAIN
OBSCURATIONS ACROSS THE CLEARWATERS INTO THE NORTHERN BITTERROOT
AND SAPPHIRES THROUGH MIDDAY TODAY. GRADUAL IMPROVEMENT CAN BE
EXPECTED THIS AFTERNOON AS WEAK HIGH PRESSURE STARTS TO RETURN.

&&

.PREV DISCUSSION... /ISSUED 333 AM MST FRI DEC 14 2007/

DISCUSSION...ONGOING SNOWFALL ACROSS NORTHWEST MONTANA AND NORTH-
CENTRAL IDAHO HAS BEEN VERY LIGHT AND ACCUMULATIONS SHOULD BE
MINIMAL THROUGH THE MORNING. THIS AFTERNOON SOME DRIER AIR STARTS
TO MOVE IN ALOFT DECREASING CLOUD COVER. DOWNSLOPING WINDS
DEVELOPING IN THE VALLEYS SHOULD BE ENOUGH TO BREAK UP THE CLOUD
COVER.

LATE FRIDAY NIGHT AND SATURDAY BRING THE CHANCE OF SOME
SIGNIFICANT SNOWFALL AND STRONG WINDS ACROSS THE AREA. A PACIFIC
STORM SYSTEM WILL MOVE THROUGH WASHINGTON FRIDAY NIGHT AND BRING
SNOWFALL TO IDAHO AND MONTANA BY EARLY SATURDAY. A TIGHT SURFACE
PRESSURE GRADIENT WILL CREATE STRONG WINDS THAT WILL MIX WITH THE
FALLING SNOW TO CREATE BLOWING AND DRIFTING SNOW THAT COULD MAKE
DRIVING CONDITIONS HAZARDOUS. WINTER STORM WATCHES ARE CURRENTLY
IN EFFECT FOR FRIDAY NIGHT THROUGH SATURDAY AFTERNOON. STRONG
SOUTHERLY WINDS ARE LIKELY FOR THE SALMON RIVER CORRIDOR UP TO
THE CAMAS PRAIRIE LATE FRIDAY NIGHT INTO SATURDAY MORNING.

A WEAK RIDGE OF HIGH PRESSURE WILL BUILD OVER THE NORTHERN ROCKIES
THE REST OF THE WEEKEND CAUSING A DECREASE IN SHOWER ACTIVITY. THE
MODELS ARE INDICATING ANOTHER STRONG SYSTEM MOVING THROUGH THE
REGION BY MONDAY. THIS SYSTEM WILL BRING MORE WIDESPREAD SNOW TO
WESTERN MONTANA AND NORTH CENTRAL IDAHO WITH SOME LOCATIONS
RECEIVING SIGNIFICANT SNOW. THE EXACT TIMING AND STRENGTH IS STILL
NOT QUITE CERTAIN. THE REMAINDER OF THE WEEK WILL BE UNDER AN
EXTREMELY ACTIVE WEATHER PATTERN WITH A FEW STRONG SYSTEMS MOVING
THROUGH...BUT THE TIMING IS UNCERTAIN. SO HAVE LEFT THE POPS ABOVE
CLIMATOLOGY.

AVIATION...A WEAK DISTURBANCE WILL CONTINUE TO MOVE THROUGH THE
NORTHERN ROCKIES TODAY CAUSING WIDESPREAD SNOW SHOWERS. ONCE AGAIN
THE MOUNTAINS AND PASSES WILL BE OBSCURED AT TIMES. THE SNOW
ASSOCIATED WITH THIS SYSTEM HAS BEEN EXTREMELY LIGHT SO ONLY
EXPECTING SIGNIFICANT REDUCTION IN VISIBILITIES NEAR HEAVIER
SNOWFALL CORES.
