TULSA, OKLA — Expect a quiet night across Green Country with a few clouds and overnight lows falling into the upper 60s and low 70s.
Wednesday afternoon, the summer heat begins to intensify as highs reach the mid-90s with a heat index above 100°. A few isolated storms are still possible, mainly over the higher terrain of southeast Oklahoma and northwest Arkansas, but most locations will stay dry.
Thursday is expected to be the hottest day of the week. High temperatures will soar into the mid to upper 90s, and when combined with the humidity, heat index values will climb to around 105° in the afternoon. Anyone spending extended time outdoors should stay hydrated, take frequent breaks, and limit strenuous activity during the hottest part of the day. A few cooling showers may occur late in the day.
Looking ahead, a weak front is expected to approach the region late Thursday into Friday. While confidence in the exact timing is still low, the front should increase the chances for scattered showers and thunderstorms from late Thursday through the weekend. Several rounds of rain and t-storms are possible.
The approaching front should also knock temperatures back closer to normal if not even below average for a few days the wrap up the weekend and start next week. We'll gradually warm back up through the end of the next week.
