GFS model and now the European model is beginning to show a more active pattern setting up around or after Christmas in parts of the Plains, upper Midwest and Great Lakes. This will be something to keep an eye on during the next few days to see if computer models continue to trend toward a stormier pattern, or if they flip to a quieter pattern. Stay tuned.
