 Fox 23 and KRMG meteorologist Mike Grogan on this Sunday morning. Hey, Mike. The heat is on for your Sunday up to 100 degrees this afternoon with the heat index over 105 with a southwest breeze. Tonight's low just 79. Up above 100 again Monday and Tuesday afternoon. By Wednesday, a likely chance of showers and storms with a cold front dropping us into the 80s for highs by Thursday. I'm certified meteorologist Mike Grogan for Fox 23 and 1023 KRMG Tulsa's News and Talk.
