A cold front will sweep through the eastern half of the country Sunday, bringing with it cooler air and wet weather.
Expect a soggy start to the day along the Interstate 95 corridor in New England, but drier and cooler conditions will follow in the afternoon. The wettest areas will be south of Pennsylvania in the Mid-Atlantic and the Southeast. Periods of rain and thunderstorms will be possible across much of the Florida Peninsula, bringing the threat for localized flash flooding. There will be some sunshine from Pennsylvania and Ohio on south and west to Texas and Oklahoma. However, clouds and a few snow showers will be downwind of the Great Lakes by the afternoon. Light snow is expected from the Dakotas to northern Missouri throughout the day.
High pressure in Nevada and Utah will create dry weather for the southern Rockies and across the Southwest into California.
A storm is expected to move into the Pacific Northwest, bringing periods of rain and snow from Washington and northern Oregon to Idaho and Montana throughout the day.
Focus: Cold and Stormy Conditions Return in February
After the second half of January turned mild for much of the nation, temperatures will plunge again in February. A major change in the weather pattern should allow arctic air to descend into the northern United States as several storm systems cross the country.
