A powerful low pressure system will bring a chance of accumulating snow to the Upper Midwest this weekend, but the big question this far out is if it'll paint a stripe of deep snow across parts of Minnesota.
For starters, it'll be warm enough for light rain to fall much of the day Friday, but temps will be cold enough for mostly snow by the time the storm arrives, which right now appears likely to happen on Sunday.
Where the snow falls is unknown at this point, but the National Weather Service is favoring a southerly storm track that would bring the heaviest snow to extreme southern Minnesota, northern Iowa and southern Wisconsin.
Computer models vary on the storm's track as well. Here's one model that shows the storm hitting southern Minnesota and most of Iowa.
"A few [models] bring a swath of heavy snow across Minnesota into northern Wisconsin, several others take it south across Nebraska, Iowa, into southern and central Wisconsin," the NWS Twin Cities says in its Wednesday morning forecast discussion.
The NWS office out of La Crosse, Wisconsin is calling it a "major storm system" that is likely to hit the area on Sunday, pointing out that at least one computer model shows a "rather robust" band of snow possibly hitting the area.
Again, way too early to pin down any guaranteed impact areas, but this storm will definitely be one to keep an eye on over the weekend, especially if you have travel plans.
