The combination of temperatures in the low 90s and high relative humidity will lead to peak heat indices around or slightly above 100 degrees this afternoon. A few spots could approach brief heat indices near 105 degrees. Scattered storms will bring relief to some. Drink plenty of fluids, wear light and loose fitting clothing, stay in air-conditioning if possible, seek shelter from the sun, and check up on relatives and neighbors. Provide pets and other animals with shade and water.
