Strong late-season cold front surges across eastern U.S., with hard freeze and even snow for some.
A 20 to 30-degree drop in temperatures will bring a temporary pause to spring.
A strong cold front is sliding across the eastern United States, bringing a quick drop in temperatures that will press the pause button on spring. A hard freeze is possible in many spots, with even a taste of snow for some in the Northeast, before a gradual return to mild weather to start next week.
The same cold front was accompanied by 70 mph winds and “extreme” fire danger across many northern states, including in South Dakota, where areas west of Rapid City were evacuated and Mount Rushmore was shut down for a time on Monday.
Temperatures up and down the East Coast could fall by as much as 15 degrees in an hour as the front surges toward and across the Appalachians late Wednesday into Thursday, just in time for the start of Major League Baseball’s regular season, with the risk of flash flooding in spots and wintry precipitation farther north.
On Wednesday morning, the cold front stretched from near Toledo, to Memphis, to just east of the Dallas-Fort Worth area. It will strengthen as it approaches the Southeast by Wednesday afternoon. . .
The brisk late-season air mass and influx of dry air will spell a fleeting reprieve from the rounds of severe weather that have targeted the South and Southeast in the past several weeks; ahead of the front, however, pockets of very heavy rain and a few strong storms are expected, along with snow to the north.
