It looks like the model guidance is in very good agreement on a major blizzard for the Midwest. It will start in Oklahoma tonight and spread into Missouri and Illinois Tuesday. The guidance is indicating some incredible snow totals, and over a foot is likely in a stripe from Tulsa to near Chicago.
The Plains have had a mild winter so far, with little snow, but that is about to change big time. If you have travel plans, in any of the affected states, change them. I suspect the Tulsa, St. Louis and Chicago airports will be shut down. Airports in Detroit and Indianapolis likely will have huge delays as well.
