Tulsa Weather: One more storm chance before summer heat and humidity arrive

After a noisy night of severe storms and damaging winds, parts of Oklahoma face another round of thunderstorms Wednesday, followed by rising temperatures and heat index values topping 100° by late week.

Wednesday Storm Threats

A weak front will push across eastern Oklahoma and set up as a focal point for one more round of showers and storms across the area.

Scattered thunderstorms are likely to develop along this boundary Wednesday evening and into tonight, some of these could be severe.

Dry But Muggy Weather Thursday

A few isolated showers could continue to linger in far southeastern Oklahoma Thursday morning. But a mid-level ridge of high pressure will begin to influence most of the region Thursday and Friday, keeping the storm track north of Oklahoma and shutting down organized storm chances.

Combined with increasing low-level moisture from persistent south winds, this will result in muggy conditions. Thursday morning lows will be in the lower to mid-70s, with highs climbing into the lower 90s.

Heat index values on Thursday — Juneteenth — will range from 98 to near 104°.

Late Thursday night into early Friday morning, a very low-end chance for a few showers will remain across far southeastern Oklahoma into west central Arkansas as gusty south winds and low-level moisture stream across this area.

Do I Need Rain Gear This Weekend?

We should not need rain gear this weekend! From Friday through the weekend, the ridge will remain close enough to suppress storm development, but warm and humid weather will continue.

Morning lows will stay in the lower to mid-70s, with highs in the lower 90s. Heat index values will range from the upper 90s to as high as 103°. Gusty south winds will persist at 15 to 25 mph.

Next Week

Looking ahead to early next week, another boundary may approach the central Plains and could bring a few thunderstorm chances to parts of northern Oklahoma.
