1. I posted a map below of the snow and ice for the rest of the day. The most snow will fall across the Northeast where the cold air is thicker allowing the precipitation to stay all snow. South of the snow area, it remains a wintry mix until the warm air can come in. All these areas will get warm by Wednesday before the next blast of cold air comes in for the later part of the week and weekend. Another weak system will come through this weekend to produce light snow once again. More on that later.
2. The next big weather event will be the severe weather that will begin Tuesday afternoon and last into Wednesday evening. We should see a squall line form late Tuesday that will move east producing wind damage, hail and even a few tornadoes. The best chance of tornado activity will be from Arkansas to eastern Texas late Tuesday. The squall line will continue into the Southeast and could extend north in the D.C. area as well Wednesday.
It's going to be a stormy period across the country, but the models seem to differ on the outcome.
The storm that is coming into the Plains will produce a wide range of weather including snow, ice and flooding rains.
The holiday time will be stormy in the Plains and Front Range of the Rockies. Travel will be impacted by the weather.
A swath of moderate to heavy snow to move from the Midwest through the Great Lakes.
A storm will streak out of the Rockies into the Great Lakes producing a swath of a snow along its path.
