...SIGNIFICANT SNOW POSSIBLE ON CHRISTMAS EVE AND CHRISTMAS DAY...

LOW PRESSURE WILL MOVE THROUGH SOUTHERN IDAHO ON THE NIGHT BEFORE
CHRISTMAS AND CHRISTMAS MORNING...WITH ITS EFFECTS LINGERING INTO
CHRISTMAS AFTERNOON AND NIGHT. THE FORECAST TREND HAS BEEN FOR
COLDER TEMPERATURES CHRISTMAS DAY...AND SO WHAT WAS ONCE EXPECTED
TO BE A RAIN AND SNOW MIXTURE NOW APPEARS TO BE AN ALL-SNOW EVENT.

FOR THE LOWER ELEVATIONS OF THE SNAKE RIVER PLAIN AND EASTERN MAGIC
VALLEY...SNOW FALL IS EXPECTED TO START AS EARLY AS THE AFTERNOON
OF CHRISTMAS EVE AND CONTINUE THROUGH CHRISTMAS DAY. ACCUMULATION
TOTALS WILL BE MAINLY 1 TO 4 INCHES...WITH LOCAL BENCH AND
FOOTHILL LOCATIONS RECEIVING AS MUCH AS 8 INCHES TOTAL. CHRISTMAS
MORNING LOWS WILL BE MAINLY IN THE MIDDLE 20S UNDER CLOUDY SKIES
WITH AFTERNOON HIGHS STRUGGLING TO REACH THE LOW 30S. BREEZY TO
WINDY CONDITIONS IN THIS AREA ARE EXPECTED DURING THE MORNING.
THIS CAN CREATE SNOW DRIFTS ON HIGHWAYS AFTER THE ROAD HAS JUST
BEEN PLOWED...AND REDUCE VISIBILITY IN BLOWING SNOW.

FOR THE MOUNTAINS OF CENTRAL AND EASTERN IDAHO...MODERATE TO
HEAVY SNOW IS FORECAST. EXPECT WIDESPREAD SNOWFALL FROM WEDNESDAY
AFTERNOON THROUGH CHRISTMAS AFTERNOON TO BE 5 TO 10 INCHES.
HOWEVER...PLACES SUCH AS THE IDAHO WASATCH AND BEAR RIVER
RANGES...AND HIGH ELEVATION SUMMITS ON HIGHWAYS SUCH AS TETON PASS
AND GALENA SUMMIT...WILL RECEIVE IN EXCESS OF 12 INCHES OF SNOW
DURING THE PERIOD. AGAIN...DRIFTING AND BLOWING SNOW WILL ADD TO
THE HAZARD OF TRAVELING THROUGH OR TO THESE PLACES.

AN EARLY DEPARTURE WEDNESDAY MORNING...IF POSSIBLE...WILL AVOID
THE HAZARDOUS WEATHER. IF YOU CANNOT LEAVE WEDNESDAY MORNING...BE
PREPARED FOR WINTER DRIVING CONDITIONS...INCLUDING SLOWER SPEEDS
AND TEMPORARY ROAD CLOSURES IN THE HIGH MOUNTAIN PASSES.

FOR YOUR RETURN TRIP...MORE SNOW IS EXPECTED ON SATURDAY NIGHT AND
SUNDAY. ALTHOUGH NOT AS MUCH SNOW IS FORECASTED...SATURDAY WILL BE
A BETTER TRAVEL DAY.
