A lot of weather going on around the U.S. Today and for the next couple of days. The biggest story will be the Nor'easter/blizzard that affects portions of the Northeast U.S. This storm is already developing This Evening, aided by a powerful 120-140+ knot upper level jet which extends from northeast Minnesota to the Carolinas. Meanwhile, warmth continues across much of the western and parts of the southern U.S. with record heat in some spots Today. A new winter storm on Monday could target the deep south!
