While dry conditions will persist along much of the Interstate 95 corridor Friday, snow and an icy mix are projected to extend from the Ohio Valley and the Great Lakes to the central Appalachians. Enough wintry mix may develop to result in slippery roads and sidewalks.
Gathering moisture will bring rain from the central Appalachians to the central and western Gulf Coast. Severe thunderstorms may also occur over the lower Mississippi and Ohio Valleys. The storms could produce a few isolated tornadoes.
The western Great Lakes to central Texas will be mainly dry, but conditions are expected to change in the central and northern parts of the region Friday night into Saturday. A storm will bring snow showers from the Great Basin to the northern and central Rockies. Rain showers farther south, over the Rockies, will gain strength as they move farther east this weekend. Heavy wind and snow may change to blizzard conditions in parts of the northern Plains, with a wintry mix over the central Plains.
While much of the Pacific Coast can expect a break from storms, a system will spread rain across the Washington, Oregon and Northern California coasts later in the day.
Focus: Weather Pattern Change Late Next Week
The weather pattern across North America will undergo another change during the middle of next week. Another round of cold weather is expected across the eastern half of the country, while the West Coast will turn warmer.
