500mb analysis from late Tuesday afternoon. A potent trough pushing through the Great Lakes today helped to produce a few severe thunderstorms and even a report of a tornado in northern Ohio of all places in early January.
That is quite an impressive looking trough digging S/E through the Great Lakes today (Jan 8) per Goes-16 water vapor satellite imagery.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
Back to winter, I mean it is early January after all. Low pressure was off to our east today with high pressure to our west. NW flow and cold air advection occurred across our area today between the low to our east and high to our west.
Quite a change in the 850mb temps between yesterday and today — +2 to +4C Monday afternoon, down to -14 to -16C Tuesday afternoon, that will activate the wind machine!
Outside of a few wind driven flakes, tonight is looking mainly dry under partly to mostly cloudy skies. Lows will range from the single digits below zero to around 10 above, and throw in a gusty NW wind of 20 to nearly 40 mph, and yeah that will certainly get your attention.
Will maintain a gusty wind on Wednesday although they will start to decrease from W-E as high pressure builds into the upper Midwest. Should see some sun Wednesday but it will be cold with below normal highs (for a change) in the single digits to lower teens.
Note: Snow chances look to ramp up on Thursday mainly over far northern Minnesota and along the North Shore of Lake Superior as winds turn to the E-SE. Chances for some snow look to continue over parts of the area for Friday and Saturday with more significant snow possible along the North Shore of Lake Superior where lake effect snow could occur Friday and Saturday with winds out of the east.
