The National Weather Service (NWS) says heat index readings in Grayson County could reach as high at 105 on Wednesday afternoon.
The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature, according to the NWS.
“August sun helping temperatures into the lower 90s, and a humid air mass will lead to elevated heat index readings Wednesday afternoon, likely peaking between 100 and 105 degrees,” the NWS said in its alert.
Officials recommend drinking plenty of water if outside during the afternoon hours, and “spend as much time in the shade as possible.”
Do not leave children or pets inside vehicles.
The air temperature will be 88 degrees by around noon on Wednesday and the low 90s by 2:00 p.m. The humidity is expected to be 80-plus percent.
