A spring storm packing tornadoes, heavy snow and rain tore through eastern Colorado and Kansas, damaging property and shutting down schools and roads.

In Texas, separate storms developed over the San Antonio area Thursday and moved north and east — dumping as much as 12 inches of rain. In Bryan, Texas, at least two homes were destroyed when a tornado moved through.

"Almost every roadway we have around here is under water," said Texas Department of Public Safety Trooper Eddie Carmon. Roads were closed in four counties because of flooding; the rain delayed or canceled some flights in Houston.

National Weather Service meteorologists said the Colorado and Kansas system spawned as many as a dozen twisters as it moved east across the two states on Wednesday night.

Up to 14 inches of snow were reported in parts of Rocky Mountain National Park in Colorado on Thursday. Jamestown, a mountain village about 20 miles south of the park, reported 10 inches of snow. Many foothills towns received about 5 inches.

No injuries were reported from any of the storms.

Randy Robbins and his wife, Linda, were working on their new home near Attica, Kan., Wednesday night when they saw a tornado approaching. They took refuge in the basement before the twister ripped off the roof and garage doors, broke windows and destroyed animal pens and a storage shed. A truck in the driveway was tossed about 50 feet.

"Everything got moved around except my tractor," Randy Robbins said.

Three homes east of Attica, in south-central Kansas, were damaged and a section of U.S. 160 was temporary closed because storm debris clogged an underpass. Rains flooded some low-lying areas in three Kansas counties.

In Colorado, wet, muddy roads prompted officials to close six school districts Thursday. Two twisters touched down Wednesday night, destroying a windmill and flattening trees near the Kansas line. Hail of up to an inch in diameter was reported.

Two tornadoes touched down Wednesday night in Cheyenne County, destroying a windmill and flattening trees near the Kansas line. The storm brought heavy rain and hail up to an inch in diameter.

Welcome rain fell on drought-parched lawns and fields on the eastern edge of the Colorado mountains. Rain ranged from half an inch at Fort Collins to 1.17 inches in the north Denver suburb of Northglenn by Thursday.
