CHICAGO (AP) — The weekend snow, ice and rain in the Midwest and eastern parts of the U.S. is just the opening act. The main event is close behind.

Forecasters say the Red River Valley will be one of the first areas to feel the effects of Arctic temperatures that will spread over the next few days. Parts of the Midwest will see subzero temperatures with single-digit lows in the East. Cold weather is expected to reach as far south as New Orleans.

On Saturday, a mix of precipitation affected a swath from Oklahoma to southern New England. High winds, including a couple tornadoes, pelted parts of the South along with heavy rain.
