( CNN ) -- Tornado watches stretched from the Texas Panhandle to central Nebraska on Wednesday as another wave of storms put portions of the Plains states and Midwest squarely in the bull's-eye again . It was the latest round of severe weather to settle over America 's heartland as warm moist air from the Gulf of Mexico saturated the area , bringing with it the risk of twisters , large hail and damaging winds . Though radar indications triggered sporadic warnings for a handful of counties in Texas , Kansas and Nebraska , no tornadoes or damage had been reported by Wednesday evening . However , a severe thunderstorm warning posted for the Kearney , Nebraska , area said golf ball-sized hail that could damage vehicles , roofs and crops was possible as the storm swept northward . In Macksville , Kansas , about 100 miles west of Wichita , residents reported wind gusts up to 80 mph , the National Weather Service said . The watches also covered most of western Oklahoma and Oklahoma City and its suburbs . One of those , Moore , was hit May 20 by a top-scale , mile-wide tornado that killed 24 people . The weather service issued a severe thunderstorm warning for the area Wednesday evening , saying hail and wind gusts up to 70 mph were possible . The threat covers more than half the country , stretching from the Canadian border to the Gulf coast and from the Eastern Seaboard to the Intermountain West . This will most likely occur in the form of severe thunderstorms , though the forecast notes there 's also a greater probability than usual of large hail , damaging winds and tornadoes . Opinion : Tornado risk goes beyond the 'Alley ' The powerful storms have been dumping heavy rain across the region , especially on portions of Kansas , Missouri , South Dakota , Illinois and Indiana , where flood warnings were in place , the Weather Service said . Multiple tornadoes were spotted across Kansas on Tuesday evening . One touched down near the north-central town of Corning , striking six farms , one of which was destroyed , according to Nemaha County emergency manager Todd Swart . But there were no reports of injuries or deaths : `` I imagine there are some dead hogs , '' Swart said . Justin Strathman saw the twister first-hand , catching the video on his cell phone . `` It was amazing , '' he told CNN affiliate KSHB . `` It was scary . I ai n't gon na lie . '' A tornado 's heading your way : Now what ? Later Tuesday , strong winds -- which National Weather Service reports said may have been a tornado , though local police said they were more likely potent straight-line winds -- caused damage near Waterford , Pennsylvania . This northwestern Pennsylvania town is about 15 miles south of Erie . CNN 's Matt Smith , Greg Botelho and Carma Hassan contributed to this report .
