New York and surrounding areas face a multi-day weather rollercoaster this week. Widespread showers and thunderstorms spread eastward into the Ohio Valley and Mid-Atlantic from Wednesday with a severe weather and flash flood threat, according to the National Weather Service. Winter Storm Warnings have been issued from the Rocky Mountains to the Upper Midwest and parts of the Northeast, with heavy snow, strong winds, and mixed precipitation forecast through March 14.
The pattern is dramatic and fast-moving. One more day of well above average, record-tying or breaking heat for the eastern U.S. Wednesday before a cold front brings cooler, seasonable temperatures Thursday. In the South, a line of strong to severe storms will move across the area overnight and continue into tomorrow morning, with primary threats of damaging wind gusts, a brief spin-up tornado or two, and small hail.

Winter Storm Warnings were issued for several counties in northern Minnesota and northwestern Wisconsin, with snowfall totals of 10 to 20 cm (4 to 8 inches) forecast, with higher amounts of 15 to 30 cm (6 to 12 inches) possible in northern Iron County from 13:00 CDT March 12 to 13:00 CDT March 13. In New Jersey, NBC New York reports isolated severe weather threats today and possible snow tomorrow. Keep an eye on official forecasts as conditions shift rapidly through the weekend.
