At least four people were killed in Pennsylvania on Tuesday and hundreds of thousands of customers were without power after severe weather that had torn across the High Plains and Upper Midwest earlier this week pushed into the Northeast and Canada.

Major storms left at least three people dead, caused extensive damage throughout the region, and left hundreds of thousands without power.

Severe storms caused widespread power outages and damage from Texas into the Northeast on Tuesday. In the Pittsburgh area, at least two people died as intense winds and rain brought down trees and power lines.
