Extreme weather was Mother Nature’s harsh holiday present for the Midwest and Deep South this year, and more wild weather is expected in the East through Tuesday.

At least 43 people were killed as tornadoes, torrential rain and flooding ravaged Texas and the Deep South on Saturday and Sunday, part of a massive storm system that curled its way across the U.S. over the weekend.

Paths of destruction were carved through the Dallas-Fort Worth metropolitan area by at least nine tornadoes on Saturday, damaging nearly 1,500 homes near the Dallas suburb of Garland, Texas, and killing 11, according to the Associated Press.

One of the tornadoes, an EF-4 on the Enhanced Fujita Scale, blasted winds of more than 180 mph across the region, according to the National Weather Service.

At the same time, a blizzard socked in the Texas Panhandle while the same storm system dropped 12 inches of rain in eastern Oklahoma, creating severe flooding across the area.

About 18 inches of snow fell in Friona, Texas, southwest of Amarillo. El Paso received 9.5 inches, according to National Weather Service snow totals.

Parts of New Mexico saw even more snow. Between 12 a.m. Saturday and 8 a.m. Monday, Cloudcroft, N.M., in the southern part of the state, received 30 inches. Bonito Lake, about 150 miles southeast of Albuquerque, received 41 inches.

The massive low pressure system causing all the extreme precipitation was curling northward Monday morning, with widespread heavy rain and embedded thunderstorms drenching much of the Midwest.

The National Weather Service is forecasting heavy rain to move eastward into the Tennessee and Ohio river valleys and the southern Appalachians late Monday. A foot of snow could fall in the Great Lakes region Tuesday.

Heavy rain, snow and ice are expected throughout the Northeast on Tuesday as the system moves into New England, where northern Maine could see up to a foot of snow.

Meanwhile, the warmest-ever Christmas temperatures on the East Coast began to succumb to cooler temperatures in the Northeast on Sunday. The New York City metropolitan area could see its first winter weather of the season Tuesday.

The National Weather Service has issued a winter weather advisory for the northern part of the New York metro area, which could see some snow, sleet or freezing rain on Monday night and Tuesday before turning to rain.
