.SHORT TERM...(THIS EVENING THROUGH THURSDAY)

AT 400 PM...IT WAS FAIRLY QUIET ACROSS THE NORTHLAND. PERSISTENT
LOW CLOUDS AND FLURRIES CONTINUED THROUGHOUT THE AFTERNOON. THERE
WERE A FEW REPORTS OF DRIZZLE EARLIER...AS WELL AS A FEW SNOW
SHOWERS. TEMPERATURES RANGED FROM 28 AT KCKC TO THE LOWER TO
MIDDLE 30S ELSEWHERE. AN AREA OF MORE PRONOUNCED LIGHT SNOW WAS
MOVING EASTWARD ACROSS THE UPPER RED RIVER VALLEY.

THE SHORTWAVE MOVING THROUGH THE UPPER RED RIVER VALLEY WILL SLIDE
ACROSS SOUTH CENTRAL CANADA AND ALSO FAR NORTHERN MN OVERNIGHT.
HAVE MAINTAINED LIGHT SNOW MENTION ACROSS THAT AREA...AND WE COULD
SEE SOME VERY LIGHT ACCUMULATION ACROSS THE NORTH. ELSEWHERE...WE
SHOULD SEE SOME PATCHY FREEZING DRIZZLE AND FLURRIES.

ON CHRISTMAS DAY...EXPECT MORE OF THE SAME WE HAVE BEEN SEEING.
LOW CLOUDS...PATCHY FREEZING DRIZZLE AND LIGHT SNOW OR FLURRIES.
WE SHOULD SEE SOME LIGHT SNOW MOVING INTO THE FAR SOUTH AND
SOUTHWESTERN PORTIONS OF THE CWA. STILL LOOKS PRETTY GOOD FOR
TRAVEL ON CHRISTMAS DAY...ALTHOUGH ROADS COULD BE A BIT SLICK DUE
TO SOME PATCHY FREEZING DRIZZLE AND LIGHT SNOW SHOWERS.

A WEAK UPPER S/W AND ASSOCIATED SFC LOW WILL TRACK EWD ACROSS THE

LIGHT ACCUMULATING SNOW TO THE SRN TWO THIRDS OF THE FORECAST AREA.
THE INITIAL BAND OF SNOW WILL BE ALONG A STRONG MID-LEVEL BAROCLINIC
ZONE ORIENTED FROM ERN SOUTH DAKOTA TO LAKE SUPERIOR. THE SECOND
