With low temperatures again forecast to only drop into the upper 70s to lower 80s for much of the area Sunday, "feels like" temperatures will quickly climb after sunrise. The heat index may reach 100 degrees in some locations as early as 10-11 AM, peaking around 110-115 degrees most places in the afternoon.
It's important to know the signs of heat exhaustion and heat stroke. When someone is suffering from either, it's important to act fast!
Hot conditions will continue for the next 7 days with the highest heat index values generally Sunday and Monday. Rain chances will be low with only isolated to widely scattered showers and storms. Afternoon highs in the mid to upper 90s can be expected most places with overnight lows struggling to drop below the upper 70s early in the week.
