A major southern storm will continue to move east into the start of next week. Rain is expected to expand east from the lower Mississippi Valley and central Gulf Coast to parts of the southern Eastern Seaboard. The rain may cause flash and urban flooding. Some of the thunderstorms near the Gulf Coast can be severe at the local level, with strong gusty winds and perhaps an isolated tornado. On the storm’s northern edge, ice and a wintry mix will glaze surfaces from parts of Tennessee to northern Arkansas and central and eastern Oklahoma.
Heavy snow is expected from central Oklahoma to parts of northwestern Texas, with possibly enough snow and ice to bring down trees and power lines. The storm will be heavier in western and central North Carolina and southwestern Virginia, from Saturday night into early Monday. The winter storm over the interior Southeast is most likely to severely impact travel and may cause widespread power outages.
Elsewhere, snow showers will riddle parts of the Great Lakes region and the interior Northwest. Much of the balance of the nation can expect dry weather and at least partial sunshine.
Focus: Dry Pattern for the North
A high-pressure system will dominate the weather pattern from the Midwest to the Northeast this weekend into the first half of next week. This will result in dry conditions across the region. There may be a few flurries near the Great Lakes.
