I did a n update on the snow map for the current storm. Had to make changes in the Northeast where more snow will fall. We need to watch for a band of 1-4 inches of snow from Northern West Virginia to southern New Jersey this evening as snow setups along the frontal boundary. The snow in the Northeast will extend into Wednesday so the longer period of snow means heavier amounts. In the Midwest, the heavy snow band is setting up across Kansas into Nebraska and Iowa where a foot of snow will occur. Thunderstorms are feeding up the Tennessee Valley causing enhanced snow and ice from Illinois into Indiana this afternoon. Significant ice may occur prior to the change over to rain. The ice map is below.

I wanted to share the snowfall and icefall images from the NDFD model which basically is very similar to my forecast map. They did show a more detailed maps of the snow and ice forecasts for the storm coming. I am concerned that a a little more snow will occur across New England than predicted. GFS and NAM went north with the snow in current runs so I may have to may some changes to the Northeast in regards to snow tomorrow. Also, some areas will get snow followed by ice and freezing drizzle. Valley locations that go over to ice probably will not get out of the hole in regards to temperatures Tuesday.
