 but with an isolated chance for a shower or thundershower early in the day, most of that north of Tulsa. High temperature Friday, 97, Saturday up to 98. By Sunday, a return to the triple digits and the heat index expected to be above 105. We will stay in the triple digits early next week before we get some rain arriving later in the week.
