(CNN) -- A tornado touched down in south-central Texas on Monday, the National Weather Service said, as a slow-moving line of storms brought high winds, heavy rains and large hail as it swept eastward.
Parts of north, south and central Texas, including the Dallas-Fort Worth area, were under a tornado watch, while a tornado warning was in effect for southern sections of San Antonio through 10 p.m., the weather service said.
Around 8 p.m. Monday, one twister landed near Natalia, a town of about 1,400 residents southwest of San Antonio.
Laura Jesse, a spokeswoman for the Bexar County Fire Marshal's Office, said a short time thereafter there "are reports of damage to one home in southwest Bexar County" but otherwise the impact appears to be limited.
"This is a rural area, so it's not that populated," Jesse said.
The tornado is related to a weather system that's also triggered flash flood watches and warnings for sections of Arkansas, Oklahoma, Texas and Louisiana. The threat of heavy rain will continue across the area into Tuesday.
Meanwhile, much of the eastern two-thirds of the country continued to have unseasonably warm temperatures, a day before spring officially starts.
Parts of Arizona remained buried under snow Monday as a surprising late-winter onslaught paralyzed travel and closed schools.
The weather agency issued a winter storm warning for the mountains of central and eastern Arizona through early Monday. Another winter storm warning was issued Monday afternoon for parts of southeast Arizona.
The city of Flagstaff was still digging out of 10 to 14 inches of snow from the weekend, which prompted school closings in the city. The city of Prescott received 8 to 12 inches.
Brandon Neuman of Flagstaff produced a time-lapse video of about a foot of snow falling on his backyard deck in seven hours.
"The other day it was 65 degrees, next day it is snowing, so it's been crazy," Neuman said. "It killed a lot of people's travel plans because the highways are a mess."
But in eastern parts of the country, balmy conditions prevailed, with temperatures well above average from Texas and the Midwest all the way to the East Coast.
