(CNN) There is some nasty weather out there and the potential for more. As night fell there were tornado warnings in Oklahoma and Texas while states like Kansas and Kentucky were getting blasted by thunderstorms, radar showed. A flash flood warning has also been put in effect for western parts of Kansas City through early Wednesday morning. At least one tornado was confirmed spotted in Texas -- north of Dallas in Grayson County, according to the National Weather Service. Matthew Day, a meteorologist with the National Weather Service office in Norman, Oklahoma, told CNN there were two circulations in northeast Oklahoma City, but the darkness prevented spotters from confirming if either was a tornado.One tornado confirmed in TexasOklahoma City appears to have avoided major damage, emergency official says
