CISCO, Texas (AP) — Forecasters say another round of severe weather could take aim at the Plains states and the Midwest today.

A strong line of storms has already moved through the Dallas-Fort Worth area this morning, pushing east and north into Oklahoma.

Several tornadoes touched down yesterday in a rural area about 100 miles west of Fort Worth, leaving one person dead and another in critical condition. The twisters damaged several structures near Cisco.

Farther north, heavy snow fell in parts of the Rockies, western Nebraska and western South Dakota.

The National Weather Service says 10 to 18 inches of snow fell in the Black Hills of South Dakota, and totals there could reach 20-24 inches by the time the system moves out.

Rapid City, South Dakota, had 8 to 11 inches, accompanied by 20-30 mph winds.

Nearly 18 inches of snow fell in southern Colorado, a state that also saw hail, flooding and tornado warnings this weekend.
