Counties affected...

Koochiching MN...Itasca MN...Cass MN...Aitkin MN...Pine MN...Carlton MN...St. Louis MN...Lake MN...Cook MN...Douglas WI...Burnett WI...Washburn WI...and Bayfield WI...

Discussion...

A cold front will move east out of the Northern Plains and will pass through Northeast Minnesota and Northwest Wisconsin Tonight and Tuesday Morning. Southerly winds along and ahead of this front will transport deeper moisture into our area and this combined with increasing amounts of instability could cause scattered showers and thunderstorms to develop from This Evening through early Tuesday.

The presence of a warm layer of air aloft may hinder thunderstorm development...but it is expected that the cap will lessen somewhat during the Evening and Overnight hours and that combined with some convergence/lift near the cold front should be able to cause a few thunderstorms to fo…
