( CNN ) -- Apparently , Mother Nature 's not a fan of Mother 's Day , and she 's letting some of us have it . At least one tornado touched down in Clay County , Nebraska , according to Loren Uden , emergency management coordinator for that county . He reported severe damage to the downtown business area in the town of Sutton . Roofs were torn off and windows were smashed . So far , just one injury has been reported there . A police officer in his cruiser on the edge of town suffered some minor cuts in his vehicle , Uden said . A farm in Sutton was reduced to rubble . `` I guess it just lifted up the house and slammed it back down , because it 's just in a pile of rubble right now , '' said McKenzie Gross , whose car was crushed by a tree in the severe weather . `` This was my cousin 's house . He and his wife lived there with their two kids . They were n't home . They got out in time . They went to my aunt 's house a couple of miles away . It 's freaky to see , '' she said . Missouri Gov . Jay Nixon declared a state of emergency Sunday as residents cleaned up from Saturday 's tornado that ripped through the small town of Orrick , east of Kansas City . The storm brought heavy rain , strong winds and hail to many areas of the state , causing significant damage to homes , vehicles and schools , and taking down trees and power lines . The National Weather Service has given the tornado a preliminary rating of EF-2 and is surveying the damage . In a statement , the governor urged residents to monitor conditions and heed weather alerts as another round of potentially dangerous weather is forecast for later Sunday . Nixon asked Missourians to `` stay alert , use caution and take shelter immediately '' if severe weather is headed their way . An area of low pressure stretching from Texas north to the Great Lakes region threatens to produce severe thunderstorms for much of the country late Sunday , CNN meteorologists warn . The storms have the potential to produce tornadoes , hail and damaging winds of 60 mph or greater . There was a moderate risk for severe storms across the Central Plains , including parts of Kansas , Nebraska and Missouri . A tornado watch has also been issued for parts of central and eastern Iowa , including the counties of Appanoose , Davis , Putnam and Van Buren and the towns of Cedar Rapids , Davenport , Dubuque and Iowa City . Shortly after the watch was issued , a tornado warning was issued along Interstate 35 , south of Des Moines . Behind the severe weather affecting the Plains , meteorologists are keeping a watchful eye on a snowstorm in the Rockies . Winter storm warnings and advisories have been issued for parts of Utah , Colorado , southern Wyoming and western Nebraska . Higher mountain elevations could see 1 to 2 feet of snow , with isolated pockets of up to 3 feet . Denver could see up to 5 to 10 inches of snow . Although snow might seem unusual this time of year , it 's actually not record-setting for the Mile High City . Denver received an inch of snow on May 11 , 2011 , and even recorded snow as late as June 12 in 1974 . The Southwest wo n't escape this wild weather either . Very strong , damaging winds will blow into parts of southern California , Nevada , Arizona and New Mexico with gusts up to 50 to 60 mph . Dry conditions mixed with gusty winds could spell a fire threat . Red flag warnings have been issued as far east as the Texas Panhandle . The only areas of the contiguous United States to escape Mother Nature 's wrath Sunday will be the Northeast and the West Coast . Most of the rest of the country will be dealing with some type of wind or storms . Maybe New York and Los Angeles remembered to send flowers ?
