A strong upper level ridge will remain over the upper Midwest thru midweek, this ridge will keep the area dry and mild with light winds, but will also be dealing with areas of dense fog especially at night and into the morning hours.

Highs in northeast Minnesota and northwest Wisconsin topped out in the mid 60s to mid 70s today (Monday), and expect similar high temps over the next several days, or at least thru Saturday the way it looks now.

The pattern from late this week into much of next week is showing signs of becoming more active per long range model guidance.

A trough is forecast to setup over the western U.S.; with upper level ridging farther to the east. A southwest flow aloft will likely develop across the Plains and Great Lakes, while multiple low pressure systems lift NE out of the Rockies.

A wetter pattern could develop across the Northland late this week into next week, but how much rain we get around here will depend on the track of the individual systems ejecting out of the Rockies. There is even a chance we see a few thunderstorms at times especially Friday-Saturday as instability increases in a mild/humid environment.

Stay tuned!

The strongest signals for above normal precipitation for about the next two weeks is over the Rockies and Northern Plains, extending into portions of the upper Midwest (green colored areas on map).

Chances are increasing for some significant snowfall over the Rockies late this week, and also sometime during the early to middle portion of next week.
