Powerful storm to affect Midwest near Christmas

The powerful storm we've been watching has finally chosen a solution; and it's west. Rather than the east coast runner like the models were showing for several days, the models have all decided it will take a track through, or near, Chicago. This means mostly rain for Detroit and the eastern subarbs of Chicago. On the west side of the storm, a mix, ice, and heavy snow will be possible. Much of mid and northern Michigan will also stay all rain as the low will track up through Lake Superior.

We're still watching the models as there is still the possibility of another shift, either further west or east, and the next few runs of the GFS and then the NAM tomorrow, will be the outlier for where the system ends up.

At this time it is too early to call on what kind of snow accumulations will take place, so we'll have to continue to monitor the situation as needed.

Note: The map posted is preliminary. This is based on the latest models and what they are showing. Being 4+ days out still, there is a likelihood of small shifts.
