IN THE WAKE OF THE MOST RECENT MULTI-DAY STORM SYSTEM THAT

AS A STRONG NOR'EASTER, MUCH MORE TRANQUIL WEATHER IS EXPECTED
OVER THE NEXT THE NEXT COUPLE OF DAYS FOR THESE LOCATIONS WHICH

THIS WILL FOSTER HEAVY SNOW OVER THE HIGHER ELEVATIONS WHICH WILL
INCLUDE NOT ONLY THE CASCADES AND THE SIERRA NEVADA, BUT ALSO THE
NORTHERN ROCKIES WHERE COLDER TEMPERATURES FILTERING SOUTH FROM
CANADA WILL HELP FACILITATE A MORE WIDESPREAD HEAVY SNOWFALL
THREAT. SOME FAVORED TERRAIN OF THE NORTHERN ROCKIES WILL INCLUDE
THE SAWTOOTH, BITTERROOTS, TETONS, AND ABSAROKA RANGE. LOCALLY AS
MUCH AS 1 TO 3 FEET OF NEW SNOW WILL BE POSSIBLE ACROSS ALL OF
