...Northern Minnesota and Northern Great Lakes...
Day 1...

An Alberta Clipper will cross ND this morning and northern MN this
afternoon before weakening as it crosses Lake Superior this
evening. However, the continental airmass its working with and
lack of upper dynamics to allow further surface development will
limit snowfall over northern MN with rates generally half inch or
less per hour. There will be some enhancement off Lake Superior
(particularly now that the track is a bit more south) to allow up
to 6" of snow to fall.

Southerly flow ahead of the wave will result in a long duration
fetch across Lake Michigan and will produce enhanced LES on the
northern side of the lake across the eastern U.P. between
Manistique and Mackinaw City late this afternoon and evening. WPC
probabilities for over 6" remain moderately high and with snow
fall rates likely exceeding 1"/hr at times this evening, localized
8" are possible.


The probability of significant icing is less than 5 percent.
