Brief Cold Snap Invades East

A winter-like cold snap that blasted the Nation`s Midsection has invaded the Tennessee Valley to the Southeast and Mid-Atlantic this morning. This blast of Canadian air will grip the eastern Seaboard today, with below-normal afternoon highs.

In the wake of a powerful spring cold front, lows have dropped to very chilly 20s and lower 30s this morning from the Mississippi Valley to the Mid-Atlantic. As a result, Freeze Warnings and Frost Advisories are in effect. Jackson, Miss., Little Rock, Ark., Nashville and Memphis, Tenn., Atlanta and the Washington, D.C., and Baltimore Interstate 95 corridor are included in these cold weather alerts. In some cases, the 24 hour temperature drops have been 30 to nearly 40 degrees compared to Tuesday morning.

Due to massive Canadian high pressure in place across the eastern U.S., unseasonably cold highs will be the norm despite abundant sunshine today. Below-average 40s and 50s will grasp the populated Interstate 95 corridor from Richmond, Va., to Boston. Slightly more seasonable 60s and 70s await the Southeast and Florida.

Although not as cold, several spots in the eastern Tennessee Valley, central Appalachians, and Mid-Atlantic will dip below freezing again tonight into Thursday morning. Therefore, Freeze Warnings and Frost Advisories are in effect. Charlotte and Raleigh, N.C., Richmond, Va. and the Washington, D.C., and Baltimore Interstate 95 corridor are included. These cold temperatures will not only threaten the growing season underway in the Carolinas, but will also threaten or even kill sensitive vegetation and early-blooming vegetation as far north as the Mid-Atlantic. Make sure to protect plants by bringing them inside or covering them with a blanket.

A more seasonal weather trend will begin for the Mid-South to Mid-Atlantic later in the work week as the cold high pressure slides off the coast and takes the Arctic air with it. The warm-up will continue into the weekend for many areas from Florida to the Northeast.
