MAIN UPPER WAVE IS MOVING THROUGH MANITOBA...WITH ANOTHER WEAK
SHORTWAVE APPROACHING FROM THE WEST. SURFACE MAP SHOWS HIGH
PRESSURE PUSHING INTO THE CWA. RADAR INDICATES A BAND OF VERY
LIGHT SHOWERS CONTINUING TO TRACK EASTWARD THROUGH CENTRAL SD.
UNDER PARTLY TO MOSTLY CLOUDY SKIES...WINDS ARE GENERALLY
NORTHERLY AROUND 10 KTS...AND TEMPS ARE IN THE 70S.

WEAK UPPER FORCING AND SOME 850-700 MB FRONTOGENESIS MAY ALLOW

SHRA/TSRA LATE IN THE WEEK AS THE STRONGER UPPER-LEVEL FLOW MOVES 
EAST AND BRINGS BETTER CHANCES OF SHORT-WAVE TROUGHS THAT WILL 
AFFECT THE CWA. THE MAIN PUSH OF COOLER AIR SHOULD COME SATURDAY 
THROUGH SUNDAY. THE ECMWF IS MUCH SLOWER THAN THE GFS IN EJECTING 
THE UPPER LOW ACROSS THE NRN PLAINS SUNDAY THROUGH MONDAY...WHICH
