Winter Storm Watch in effect from late tonight through late Monday night for the counties shaded in blue on map.
This includes the Counties of Southern St. Louis and Carlton in northeast Minnesota, and Douglas, Bayfield, Ashland and Iron Counties in northwest Wisconsin.
Note: Upgrade to a warning or advisory will occur sometime this afternoon. And other parts of the Northland will likely be in a winter weather advisory for this event from late tonight thru Monday.
Here’s my snowfall potential map for this next storm
Some shifts in the snowfall areas (north or south) are possible by later this afternoon, stay tuned.
We will get some phasing to occur with the northern and southern branches of the jet stream during the next 24 hours, but not a complete phasing between the two with the stronger southern low (over Arkansas) staying well SE of our area as it heads NE toward the Ohio Valley on Monday.

…Sunday morning weather update…
•Snow event for Sunday night through Monday night remains on track.
•Potential for a 2 to 6 inch snowfall across northeast Minnesota and northwest Wisconsin.
•Some uncertainty on when the snow will start, and where the heavier bands of snow will setup, but in general it looks like will see some light snow at times across northern Minnesota today-this evening, then snow will expand farther south later tonight.
•This snow should be a little fluffier (drier) compared to the cement that fell on Thursday.
•Winds gusting 15 to 30 mph on Monday with areas of blowing snow possible, especially near Lake Superior.
•Potential for periods of lake enhanced snow on Monday along the South Shore of Lake Superior, extending west to Duluth, and possibly north to Two Harbors. Surface winds will start out from the E-NE but quickly back to the N-NE during the day on Monday, while winds at 850mb remain out of the E-NE thru Monday evening. 850mb temperatures start out relatively mild for lake enhanced snow, but cool nicely on Monday, down to around -10C, and will cool further Monday night to -12 to -15C, but by that time the threat for lake enhanced snow will have shifted to the South Shore, east of Duluth and Superior. Snow totals of 6 to 8 inches (or more) are a possibility along the South Shore of Lake Superior, and possibly as far west as Duluth depending on how long winds remain favorable for lake enhanced snow in the Twin Ports area.
More updates later today
