NEW YORK (Reuters) - Killer tornadoes in the U.S. Southeast and historic subzero cold as far south as Texas were blamed on Tuesday for seven deaths and massive power outages that canceled COVID-19 inoculations and threatened to disrupt vaccine supplies.

Treacherous weather will maintain its grip on many parts of the United States from Tuesday through Friday, with up to 4 inches of snow and freezing rain expected from the southern Plains into the Northeast, forecasters said.
