Thunder Bay – Snow ahead of a fairly intense Alberta clipper approaching from South Dakota is expected to move into the Lakehead area this morning. Cold easterly winds will pick up extra moisture from Lake Superior and as a result, the snow will be heavy at times with a general snowfall of 15 to 20 cm expected by the time the snow ends after midnight tonight.
Brisk easterly winds will also cause blowing snow in exposed areas. Motorists should be prepared for hazardous winter driving conditions due to accumulating snow on untreated roads and very low visibility in heavy snow and blowing snow.
