Weather Synopsis

There was an upper level trough to our east today with a ridge to our southwest.  The ridge to our southwest will build over the upper Midwest through Tuesday with high pressure covering the upper Great Lakes.

Will have mainly clear skies across the Northland tonight through Tuesday night.  Expect areas of low clouds and fog to redevelop later tonight before it burns off by mid morning Tuesday, the greatest potential for low clouds and fog will be near Lake Superior especially along the South Shore, west toward the Twin Ports.

Lows tonight will be in the 40s to lower 50s but some 30s are expected mainly in parts of eastern Minnesota and northwest Wisconsin.  Highs Tuesday will warm into the 70s and lower 80s again with cooler 50s and 60s near Lake Superior.

Note:  A chance for showers and perhaps a few thunderstorms returns to the Northland for the Wednesday-Thursday time frame as a weak system approaches from the west.  Temperatures will remain on the mild side though with Wednesday likely warmer than Thursday the way it looks now.
