A significant, disruptive coast-to-coast storm is going to impact millions of Americans this week, with heavy snow, ice, flooding and severe weather all possible. This multi-threat storm will begin on Tuesday east of the Rockies, ramp up on Wednesday, and last into early Friday. Some locations could see winter impacts for over 48 hours straight. #winterstorm #coasttocoast #coasttocoaststorm #snow #ice #flooding #severestorms #severeweather #us
