WINNIPEG BACK TOWARDS CANDO SHOULD CONTINUE TRACK INTO NORTHWEST
ONTARIO THROUGH THE DAY TODAY...COINCIDENT WITH THE MID LEVEL

OF THE AREA ALONG AND NORTH OF HWY 200...WHILE SCT RAIN SHOWERS
ARE MORE LIKELY TO WRAP CLOSER TO THE LOW CENTER MAINLY NORTH OF
THE HWY 2 CORRIDOR. EXPECT SCT RAIN SHOWERS IN FAR NORTHEASTERN ND

MOVING INTO THE LAKE OF THE WOODS AND NORTHERN RED LAKES REGION IN
THE AFTERNOON.

LEVEL JET WINDS AND FOR A MORE NORTHWARD MOVEMENT IN MOISTURE
OVERTIME.

MOVES INTO THE PACIFIC NORTHWEST BY THE END OF THE PERIOD. ZONAL
