Weather

A powerful nor’easter Thursday will bring heavy snow and gusty winds to northern New England. Accumulation is expected to reach 1 to 2 feet, with extensive blowing and drifting snow. Minor to moderate coastal flooding may occur at times of high tide. A second batch of heavy snow will fall over the Upper Midwest. Snow showers will extend from the Great Lakes to the central and southern Appalachians. The circulation of air around the storm will bring chilly conditions from the northern Plains to the East Coast and the eastern part of the Gulf Coast, despite the return of sunshine.

The Mississippi Valley to the Rockies and the Southwest can expect a dry day, with sunshine. Several areas of high pressure will extend from Utah to South Dakota and Louisiana.

A Pacific storm will produce drenching rain and mountain snow from Northern California to Washington and northern Idaho. Enough rain may fall along the coast, from western Oregon to western Washington, to cause flash flooding and mudslides. Snow will fall on the passes in the Sierra Nevada, making roads slippery. The snow should reach parts of western Montana later in the day.

A low-pressure system over the Pacific Ocean will approach California this weekend. Rain will fall across much of central and Southern California, mainly from Saturday afternoon into Sunday. Mudslides may develop in some of the recent burn areas.
