CONDITIONS A GOOD BET WITH THIS SYSTEM...ESPECIALLY FOR RIDGES AND
EAST TO WEST ORIENTED CANYONS/PASSES WITH THE PASSAGE OF THE COLD
FRONT ON FRIDAY MORNING. THIS SYSTEM HAS THE POTENTIAL TO BRING
SNOW AND BLOWING SNOW ADVISORY CRITERIA TO MANY PORTIONS OF THE
FORECAST AREA OUTSIDE OF THE WINTER STORM WARNING AREA. THE SEELEY
LAKE/POTOMAC AREA...THE BITTERROOT AND SAPPHIRE MOUNTAINS...ALONG
WITH THE SOUTHERN CLEARWATERS AND HIGHER ELEVATIONS OF SOUTHWEST
MONTANA WILL LIKELY BE IMPACTED BY THE SNOW AND WIND ON FRIDAY BUT
WILL LET LATER SHIFTS TAKE A CLOSER LOOK. UPGRADED THE HIGH WIND WATCH
FOR THE CAMAS PRAIRIE AND HELLS CANYON AREA GIVEN THE GOOD
POTENTIAL FOR 60-65 KNOT WINDS JUST ABOVE MOUNTAIN TOP LEVEL TO
MIX DOWN INTO THE GRANGEVILLE AREA/CAMAS PRAIRIE AND GOOD TERRAIN
CHANNELING COMBINING WITH A STRONG SURFACE PRESSURE GRADIENT FOR
THE HELLS CANYON AREA. THE POTENTIAL FOR A SIGNIFICANT SNOW
BANDING EVENT OVER NORTH CENTRAL IDAHO AND WEST- CENTRAL MONTANA
EXISTS FOR FRIDAY NIGHT/EARLY SATURDAY MORNING. INCREASED PRECIP
CHANCES AND SNOWFALL AMOUNTS OVER THIS AREA AS A RESULT.

SATURDAY THROUGH WEDNESDAY...GLOBAL MODELS IN FAIRLY GOOD
AGREEMENT WITH A SEASONABLY COLD AIRMASS REMAINING IN PLACE
THROUGH THE BEGINNING OF THE WORK WEEK. THE MOUNTAINS THEN
GRADUALLY WARM MONDAY THROUGH WEDNESDAY BUT VALLEY TEMPERATURE
INVERSIONS WILL LIKELY KEEP MANY OF THE LOWER AND MIDDLE ELEVATION
VALLEYS BELOW AVERAGE THROUGH AT LEAST WEDNESDAY.

&&

.AVIATION...ISOLATED RAIN AND SNOW SHOWERS CONTINUE TO OVER NORTH
CENTRAL IDAHO AND WESTERN MONTANA OCCASIONALLY OBSCURING MOUNTAINS
AND REDUCING VISIBILITIES. A WARM FRONT AND THE LARGE AREA OF
STRATIFORM PRECIPITATION ASSOCIATED WITH THE FRONT WILL MOVE INTO NORTH
CENTRAL IDAHO THIS MORNING AND THEN INTO WESTERN MONTANA DURING
THE AFTERNOON. MOUNTAINS AND MOUNTAIN PASSES WILL BE OBSCURED WITH
MAINLY MVFR CEILINGS AND LOCAL IFR CEILINGS AND VISIBILITY IN
LIGHT TO MODERATE SNOW AND RAIN FROM SOUTHWEST TO NORTHEAST DURING
THE DAY. STRONG WINDS AREA EXPECTED TO DEVELOP OVER NORTH CENTRAL
IDAHO THIS EVENING.
