A developing storm system is expected to deliver widespread rain, damaging winds, severe storms, and even snow to the eastern half of the US this weekend. The Fox Forecast Center expects a disruptive storm that will impact millions of Americans, creating travel trouble and leading to power outages along the East Coast. The storm comes as a trough of low pressure rolls out of the western US on Friday, triggering the development of a surface low over the central Plains. This initial low will kick off the event with widespread rain and some snow in the Upper Midwest by Saturday.
