Widespread subzero lows are expected north of the Ohio River by this time, and subfreezing highs are expected well into the Deep South. reaches the Gulf of Mexico & develop a wave of low pressure along it. Moisture flowing north over the boundary will create interesting weather to say the least for the Deep South and into the Southeast U.S. for Tuesday and Wednesday.
