Continuing to watch the middle of next week for a storm that could develop and impact the Upper Midwest and Western Great Lakes with rain and accumulating snow.  One thing that looks pretty certain in the computer models is a return to colder temperatures after next Tuesday, winter is not over, but then again its only March.
