 Your Sunday will feature temperatures that were hotter than today with highs in the mid to upper 90s with heat index values making it feel anywhere from around 100 to 105 during the hottest part of the day. An approaching cold front tomorrow will also bring the chance for some showers and storms, some of which could be strong to severe with damaging winds being the primary threat.
