"Forecasters warn of a bizarre spring pattern that is expected to sweep unseasonably raw weather east of the Rockies. The arctic plunge could shatter dozens of records and notch temperatures chillier than Christmas Day in some cities.
Overall, highs will hover around 10 to 25 degrees below average Friday into Sunday in the East.
"This is certainly a powerful shot of arctic air and will bring the coldest Mother's Day weekend in quite some time," CNN meteorologist Taylor Ward said.
A frost is possible as far south as the Carolinas and Southeast, according to the Weather Channel, and wet snow is likely Friday night and Saturday in parts of the Northeast. Lake-effect snow is possible around the Great Lakes.
The extreme weather is fueled by two high-pressure systems – one near Greenland and another "omega block" pushing north from the West Coast – that will force the jet stream to dive southward over the Great Lakes and Northeast, the Weather Channel said. "
