KEY MESSAGES

Updated at 150 AM CDT Thu Jun 11 2026

- Severe thunderstorm risk on Thursday evening. Damaging wind gusts and large hail are the primary hazards.

- Hot & muggy conditions continue on Thursday and again by Saturday, with heat indices near and above 100-105 degrees in the afternoon and evening. - Active pattern continues into the weekend, with additional chances for rain and storms. Locally heavy rain/flooding possible.

NEAR TERM

(Through Thursday) Issued at 150 AM CDT Thu Jun 11 2026

Despite introducing a frontal passage to the forecast today, hot and humid conditions and chances for storms will persist. Broad upper troughing remains positioned across the western two-thirds of the CONUS, with early morning water vapor showing a maturing upper system moving quickly eastward across the Northern Plains.

While the most significant impacts from this system will remain displaced to the north, a trailing surface boundary is forecast to move slowly from northwest-to-southeast through the day, approaching the I-44 corridor by this evening. A prominent thermal ridge and pre-frontal "torching" will combine with high surface dewpoints to yield another afternoon with heat indices >105F. The epicenter of heat risk will shift south-east (into more of central/southwestern Oklahoma) compared to prior days. A Heat Advisory has been initiated, centered along the I-44 corridor, from 1 PM to 6 PM today.

The arriving front will also introduce a greater overall chance for showers and storms this afternoon, evening and night. This includes a risk for strong-to-severe thunderstorms with potential for damaging downburst wind gusts and perhaps intermittent large hailstones with any more dominant/sustaining updraft.

SHORT TERM

(Thursday night through Saturday night) Issued at 150 AM CDT Thu Jun 11 2026

An occasionally stormy period will continue into Friday morning, as modest ascent continues atop the sagging frontal zone. While severe weather chances are currently forecast to diminish dramatically after 10-11 PM on Thursday, the risk for locally heavy rainfall and flooding looks to increase by this time, particularly across southeast Oklahoma.

A modified airmass and lingering clouds/light precipitation will make for a notably "cooler" day (heat indices in the low-90s) north of the Red River on Friday. Depending on the ultimate position of the front/moisture axis, >100F heat indices remain possible for portions of far southern Oklahoma and western-north Texas. The forecast remains generally drier for Friday afternoon and evening, though will monitor low-amplitude upper waves moving eastward across the southern High Plains for low rain/storm chances late.

A predominately dry period will be rather short-lived, as another active period of rain/storm chances looks to return by Saturday afternoon and continue into Sunday, coincident with the passage of a stronger surface front. Some risk for strong-severe storms and locally heavy rainfall leading to flooding appear evident across the region. Another hot and humid afternoon is expected prior to storms on Saturday, especially across northern Oklahoma just ahead of the front.

LONG TERM

(Sunday through Wednesday) Issued at 150 AM CDT Thu Jun 11 2026

Rain and storm potential will linger into Sunday, especially across the southern one-half of Oklahoma and north Texas. Coverage/chance looks to slowly end from south-to-north by Monday. The stronger front/more modified post-frontal airmass will also yield much cooler conditions by Sunday into next week, with low to mid-80s highs and lower humidity.

AVIATION

(06Z TAFS) Issued at 1007 PM CDT Wed Jun 10 2026

While the last set of TAFs were kind of benign and fairly straightforward, this set definitely is not. Over the next several hours, no issues at all, other than the occasional report of haze along the Red River, but even that isn't coming with low visibilities. While there might be a few high clouds moving into Oklahoma from the storms in Kansas, cloud cover won't be much of an issue until nearly 00Z tomorrow.

Cold front will begin to make its way into Oklahoma as early as 18Z at KWWR, the remaining terminals will be affected between 20 and 23Z Thursday afternoon. As the front moves in, there could be a few showers or thunderstorms along the front, the better chances come a few hours later behind the front. Thunderstorm chances increase for most of the sites between 23Z and 06Z tomorrow.
