Tonight
A shortwave trough will move just to our west and north tonight.
Soundings remain rather dry, so not anticipating much of a
chance of rain. Low temperatures will range from the mid-50s to
lower 60s.
Tuesday through Friday
A 500 mb ridge of high pressure will keep the area dry and
unseasonably warm (10 to 15 degrees above normal). High
temperatures will primarily range from the upper 70s to mid-80s.
There might be a small chance of showers just west and
northwest of the area on Wednesday night. Other than that the
Upper Midwest looks to remain dry.
Next Weekend
The 500 mb ridge slides just far enough east that some
shortwave troughs ejecting out of the western longwave trough
may bring some rain chance to the area. In addition, there are
some indications that a surface front may meander across the
region. High temperatures will range from mid-70s to mid-80s.

A shortwave trough will move to the west and north of the area
tonight. This system will produce some 3 to 15K foot clouds
west of the Mississippi River and 15-25K elsewhere tonight and
Tuesday morning. In addition, a well-mixed boundary layer should
inhibit the fog potential.
