Sunshine and dry conditions are expected to continue in New England on Friday as a dry air mass from Canada moves off the coast this weekend.
Farther south and west, a slow-moving storm is expected to spread clouds, rain and thunderstorms from the middle and lower part of the Mississippi Valley to the Ohio and Tennessee Valleys, the central and southern Appalachians, the Carolinas and much of the Mid-Atlantic. Some storms may be severe over the Midwest and the South, with possible damaging winds, hail and isolated tornadoes. Most of the storms in the South will develop near and north of Interstate 20, along with spotty storms over the Florida Peninsula.
Much of the Plains and the upper Great Lakes can expect dry weather. Scattered thunderstorms will affect eastern Colorado late in the day. The storms will move east at night, bringing heavy rain to parts of the central and southern Plains.
Showers and thunderstorms are expected to dampen the northern Rockies and the northern High Plains, while much of the West will be dry. Heat is projected to build over the interior Southwest.
FOCUS: Storms To Occur This Weekend in East
Showers and thunderstorms are forecast from the Tennessee Valley to the Northeast this weekend. Flash flooding may occur in spots. Sunday’s storms will develop ahead of a cold front, which will bring drier air over the Northeast and Mid-Atlantic early next week.
