A winter storm is expected to bring snow and ice to the Midwest and Northeast beginning Wednesday. Here's which states will be impacted.

Meanwhile, a swath of the Central and Eastern U.S. was under winter weather advisory, which the NWS issues "for any amount of freezing rain, or when 2 to 4 inches of snow (alone or in combination with sleet and freezing rain), is expected to cause a significant inconvenience, but not serious enough to warrant a warning."

A storm is expected to bring wintry precipitation to central Pennsylvania from just after midnight until Thursday morning.
