MAIN CHALLENGE THIS MORNING WILL BE TEMPERATURES. SFC ANALYSIS
SHOWS LOW PRESSURE MOVING FAIRLY RAPIDLY SE FROM SD...WITH PCPN
ENDING AND WINDS DECREASING. TEMPERATURES NEAR THE CANADIAN BORDER
LOOK TO DIP BELOW ZERO IN COLD ADVECTION BUT CLOUD COVER REMAINS
OVER THE AREA AND LOOKS TO KEEP VALUES FROM DROPPING FARTHER.
SHORT TERM MODELS IN AGREEMENT TO HOLD CLOUD COVER EARLY BEFORE
BECOMING PARTLY CLOUDY LATER IN THE DAY. WINDS GRADUALLY
DECREASING THROUGH THE MORNING HOURS AND...COMBINED WITH
ENDING SNOWFALL...HAS ALLOWED VISIBILITIES TO RISE. THUS...HAVE
CANCELED THE WINTER WEATHER ADVISORY.

TONIGHT INTO THURSDAY...CANADIAN HIGH PRESSURE AGAIN SLIDES OVER
THE FCST AREA. WITH CLEARING SKIES...COOLER AIR AND FRESH
SNOW...EXPECT OVERNIGHT LOWS ACROSS MOST OF THE AREA TO APPROACH
10 BELOW ZERO...BRINGING THE COLDEST TEMPERATURES OF THE SEASON SO
FAR. HOWEVER...FOR THANKSGIVING...LOOKING FOR HIGH PRESSURE TO
SLIDE SE. RETURN FLOW BEHIND THE RIDGE WILL ALLOW TEMPERATURES TO
REBOUND AHEAD OF THE NEXT SYSTEM FORECAST TO CROSS THE REGION
THURSDAY NIGHT AND FRIDAY.

.LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 359 AM CST WED NOV 26 2014

THURSDAY NIGHT THROUGH FRIDAY NIGHT...ANOTHER SYSTEM IS FORECAST
TO CROSS THE AREA...WITH MODELS IN GOOD AGREEMENT ON PLACEMENT OF
SURFACE FEATURES. RETURN FLOW AHEAD OF THE SYSTEM WILL ALLOW HIGH
TEMPS TO REBOUND BACK INTO THE 20S. FOR THIS SYSTEM...THE
BAROCLINIC ZONE IS EXPECTED TO SET UP A LITTLE FARTHER
NORTH...BRINGING MOST OF THE NEW SNOW ACROSS NRN PORTIONS OF THE
REGION...WITH 2 TO 4 INCH AMOUNTS ANTICIPATED ATTM. WILL MONITOR
PROGRESSION OF THE SYSTEM AND REFINE THE FORECAST AS NEEDED.

FOR SAT THROUGH TUESDAY...THERE WILL BE THE CHANCE FOR SOME LIGHT
SNOW SAT AHEAD OF THE NEXT COLD FRONT. TEMPS WILL COOL WELL BELOW
NORMAL BY SUNDAY...WITH HIGHS IN THE SINGLE DIGITS. MONDAY MORNING
LOWS COULD BE WELL BELOW ZERO...WITH A 1040MB HIGH OVERHEAD AND
FRESH SNOW FOR MOST OF THE REGION. TEMPS WILL MODERATE BY NEXT TUE
AS 850MB TEMPS CLIMB ABOVE 0C. THERE COULD BE STRONGER SOUTHERLY
