Tonight’s live update rundown: 1. A Heat Advisory is in effect for the ArkLaTex Wednesday. The heat index will again likely surpass 105 degrees. 2. Not much relief from the heat is on the way as daytime temperatures will stay slightly above normal. 3. Rain will be hard to find for most of the next week. There is some slight hope by the middle of next week. 4. We could crank up the heat even more during the last week of July. Some triple-digits appear in tonight’s 16-day ‘Grain of Salt’ outlook.
