Winter storm
January is in full swing in the eastern half of the United States where temperatures and wind chills are below zero in the Northern Plains and New England.

The arctic air spills all the way into the Mid-South where the wind chill is in the teens in Atlanta and Memphis this morning.

By tonight into Tuesday morning, the coldest air moves into central Florida where wind chill alerts have been issued and there are wind chills in the 30's in Orlando.

After this cold blast in the East our attention turns to a new cross-country storm to move from West to East this week with snow, ice and rain.
