WINTER STORM WATCH IN EFFECT, THE DETAILS...

A late week storm will bring the threat of several inches of snow and some ice Friday afternoon and night to many parts of the central Midwest.

These are the latest snowfall forecasts on the models. Right now the GFS and Canadian are substantially heavier and what I would consider to be outliers unless the cold air can hold longer.
