A Heat Advisory is in effect through at least Sunday for all of Arkansas as the heat index will range from 105 to 110+ degrees. We have a slight chance for showers and storms today, but slightly better chances arrive Sunday, especially across southern Arkansas as a disturbance passes by your area. The ridge of high pressure will not be as dominate next week and this should allow for slightly lower temperatures next week along with greater storm chances during the heating of the day. Please stay hydrated, take frequents breaks, check on the elderly, and take care of your pets. Be sure to follow us on Twitter! @KATVNed, @KATVBarry, @KATVToddYak and @KATVMelinda.
