A low pressure system is expected to travel across the Winnipeg River basin late this evening and into tomorrow. Because temperatures are low, precipitation is expected to fall as snow, with accumulation in the 10 to 20 cm (4 to 8 in) range. There is a chance for freezing rain along the border with Minnesota.
The current level of Lake of the Woods is 322.41 m (1057.8 ft), a 40th percentile level, in the normal range for this time of year.
