 Oklahoma is one of 25 states that will be under heat advisories for the next two days. Forecasters say the heat index could soar up to 112 degrees. An extreme heat warning is already in effect for eastern Oklahoma. The good news is there's a cold front on the way that should arrive late Tuesday night or early Wednesday, which could bring severe storms but a much-needed cool down with temperatures in the 80s and 90s. A fact check of statements by State School Superintendent Ryan Walters range from misleading to false.
