DENVER (AP) — The jet stream hunkered to the south Wednesday, promising to bring nearly a week of temperatures that could dip to 20-below or worse in the northern midsection of the country, and forcing much of the rest of the nation to deal with unexpectedly cool temperatures. In Minnesota, the cold has forced Salvation Army bell ringers inside and cancelled holiday parties, while dense, cold air sunk into Rocky Mountain valleys and kept some lower elevations below freezing in the West.
HARTFORD, Conn. (AP) — As gunfire boomed over and over in the background, a janitor begged a 911 dispatcher to send help, saying, "There's still shooting going on! Please!" A woman breathlessly reported seeing a gunman run down a hall. And a teacher said she was holed up in her classroom with her children but hadn't yet locked the door.
