A quick update before one of the busiest travel days of the year tomorrow. Looks like we are still in store for a clipper moving across northern Minnesota and another shortwave trough cutting across southern Minnesota and Wisconsin.
The southern storm track for tomorrow continues trending further south along the Iowa/Minnesota bordre, while the northern branch looks to stay mostly north in Canada. Because of this, it looks like the highest amounts will fall in central Minnesota, mostly west of the Twin Cities, and should startup right before daybreak and continue into the early evening hours with amounts varying from about 2-4" in most areas. Just enough to give some great Thanksgiving Eve/Day skiing across central Minnesota and Wisconsin.
As for lake effect on the South Shore and UP will kick in after the storms move off to the east quickly during Wednesday evening. So should see lake effect snow showers pick up in ernest Wednesday evening and throughout Thanksgiving day. However, because of a lack of solid winds and moisture, amounts should be modest, only in the 3-6" range.
As for the rest of the area for Thursday and Friday, most areas should see a break in the action before the next clipper moves through on Thursday night into Friday. This one looks to cut right across northern Minnesota and Wisconsin, so most areas should see at least snow showers Friday morning and an increase in lake effect snow showers for the UP. However, during the past model runs the clipper has looked drier and faster moving that the beginning of the week, so not looking super impressive in terms of snow amounts.
For the weekend, it looks like we could see another clipper on Saturday night before the extremely cold air starts digging in deeper with the large trough that's been sitting over the area for the past two weeks. A quick look ahead to Sunday and Monday shows our first good chance of widespread below zero temperatures as we flip the calendar over to December.
