An Alberta clipper will track into Minnesota this morning and then continue southeastward to Lake Huron by Friday morning. Snow associated with this system will spread over Western Lake Superior early this morning.

Though Lake Superior is mostly ice covered, added moisture from the lake is expected to boost total snowfall amounts slightly along the northwestern and northern shores into the 10 to 15 cm range. In addition, local blowing snow will be possible with gusty easterly winds. A snowfall warning (issued when 15 cm falls within 12 hours) is not expected, however conditions will be monitored closely.

The snow is expected to taper off Friday morning.

Travellers are urged to exercise caution as heavy snow and blowing snow could result in sudden reductions to visibility.
