  • For the next six to ten days, much of the country will see below average temperatures. An area stretching from Montana to West Virginia and as far south as parts of Louisiana will be colder than normal.

  • Early this week, heavy showers will impact travel in the southeast. The downpours will give way to only isolated flooding, since much of the region has been suffering an extended period of dry conditions.

  • The northeast region will start the week very cold, with temperatures falling into the teens and 20s by early Tuesday as far south as Pittsburgh and Columbus, Ohio. By the middle of the week, some warm, milder air will be creeping up the east coast, peaking with temperatures in the 70s in many areas by Friday. The weekend outlook at this point is potentially much more stormy.
