A sprawling storm that dumped buckets of rain on Kentucky and Tennessee on Saturday is spreading across the East Coast on Sunday and spraying a wintry blast of rain, snow, sleet and freezing rain.

The system is expected to continue unleashing dangerous weather into Monday. Power outages, downed trees and hazardous road conditions could disrupt daily life and upend travel plans.

Bob Oravec, a meteorologist with the Weather Prediction Center, called the system a “high-impact storm” and said that the most severe weather on Sunday was likely to occur in the Northeast, where snow could be consistently heavy or turn into sleet and freezing rain.

Precipitation is forecast to subside across the East Coast on Sunday afternoon into early Monday, but the storm will continue to hang on, with damaging winds up to 70 miles per hour expected and lake effect snow continuing to fall over the Great Lakes through late Monday, even into Tuesday.

Across many parts of the Northeast, the snow is set to turn into sleet and freezing rain through Sunday night.

“Ice accumulations up to a quarter inch are forecast for some areas, making driving conditions dangerous,” the Weather Prediction Center said.
