Here is some additional information on the weekend storm:
Tornadoes and Severe Thunderstorms
Here are the expected snows before 6am Saturday.
The computer models continue to be all over the place for the potential weekend snow storm. This is the U.S. NWS's GFS model which snows nuisance snows from northeast Missouri to Flint, Mich.
However, the ECMWF continues to snow a major snow storm:
The snow would be falling on Oklahoma and Kansas Saturday and moving east on Sunday.
Interesting all of the models show it snowing at Chicago on Sunday. If you plan to fly to or through O'Hare or Midway you might want to think about moving the flight up a day.
This is what we know right now.
