MAIN CHALLENGE IS WINDS FOR TODAY. SFC LOW PRESSURE IS SITUATED
OVER THE GREAT LAKES...WITH NORTHERLY WINDS AND COLDER AIR
FILTERING SOUTH OUT OF CANADA. THE CENTER OF HIGH PRESSURE IS
SITUATED IN SE SASKATCHEWAN AND IS FORECAST TO SHIFT E LATER IN

LEVEL SUPPORT. THE RESULT WILL BE A TIGHTENING GRADIENT THROUGH
THE AFTERNOON...INCREASING WINDS WITH GUSTS UP TO 40 MPH...SO
CONTINUED THE WIND ADVISORY FOR THE RED RIVER VALLEY WEST TOWARD
THE DVL BASIN. AS THE LOW DEPARTS NE ACROSS ERN ONTARIO AND THE

FOR TUESDAY NIGHT INTO WEDNESDAY...ANOTHER CLIPPER IS FORECAST TO
CROSS THE REGION...BUT MODELS OVER THE LAST FEW RUNS KEEP
INDICATING A MORE SOUTHERLY TRACK...AND ADJUSTED POP AND WX GRIDS
ACCORDINGLY. GENERAL SNOWFALL AMOUNTS WILL BE A BIT HIGHER IN THE
DVL BASIN WITH AROUND 2-3 INCHES...WITH LESSER AMOUNTS OVER THE
REST OF THE AREA. TEMPS WILL DROP AGAIN BEHIND THE SYSTEM WITH A
QUICK SHOT OF COOLER AIR...KEEPING TEMPS FOR THE MOST PART BELOW
SEASONAL NORMS.

FOR THANKSGIVING THROUGH SUNDAY...TEMPERATURES SHOULD REMAIN
BELOW NORMAL WITH A FEW CHANCES FOR SOME LIGHT SNOW. THERE COULD
BE A BAND OF WAA INDUCED LIGHT SNOW THU NIGHT INTO FRIDAY IN THE
NORTH AHEAD OF THE NEXT COLD FRONT BY SAT. THERE ARE STILL SOME
MODEL DIFFERENCES WITH REGARDS TO TIMING/PLACEMENT...AND WILL
CONTINUE TO UTILIZE THE MODEL BLENDED SOLUTIONS. MODELS WARM TEMPS
