Milder, wetter days ahead for the Heartland
A storm system crossing the south-central U.S. will reach the southern Atlantic Coast on Thursday.
Two-day rainfall totals across the Deep South could reach 1 to 3 inches or more (except for mostly dry weather in southern Texas and peninsular Florida), while Southern thunderstorms will continue to produce local wind damage and isolated tornadoes.
Subsequently, the storm will begin to merge with a disturbance over the Great Lakes region. The ensuing low-pressure system will intensify on Friday and Saturday well east of the Atlantic Seaboard, generating windy weather and snow showers across the Northeast.
Cold air will briefly trail the storm into the southern and eastern U.S., but temperatures will quickly rebound to above-normal levels by early next week. In contrast, cooler air will overspread much of the West, but bitterly cold conditions will remain mostly north of the Canadian border. Some frigid air may edge across northern Plains by late in the weekend and early next week.
Elsewhere, widespread but generally light and disorganized precipitation will develop across the western U.S., starting on March 6-7, spreading as far east as the Mississippi Valley by early Monday.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of near- or above-normal temperatures and precipitation across most of the country.
In fact, cooler- and drier-than-normal conditions should be limited to the Pacific Northwest.
