KEY MESSAGES

Updated at 116 AM CDT Tue Jun 30 2026

- Hot and breezy conditions to continue this week.

- Excessive heating will return Friday & especially on Independence day with heat indices exceeding 105 degrees

- Some relief from the excessive heat Saturday night into Monday when our next opportunities for rain/storms chances return.

NEAR TERM

(Through Tuesday) Issued at 116 AM CDT Tue Jun 30 2026

Currently storms coming off the Texas Panhandle across parts of southwest Oklahoma will produce strong to low-end severe wind gusts across parts of southwest Oklahoma as they decay into a weaker less unstable environment during the early morning hours.

The Southern Plains remains between two weather patterns with an upper ridge & surface high across the Southeastern U.S. and deep amplitude trough across the Western U.S. A surface low lee of the Colorado Rockies will maintain a tight pressure gradient across our area maintaining windy conditions out of the south. Our low-level jet may weaken slightly this afternoon yet keeping wind gusts between 25-35 mph. Temperatures expected to heat into the upper 90s with a negligible heat index. By late afternoon into the evening hours, a series of shortwave disturbances in the mid-levels ejected downstream from the aforementioned trough may come up through western Texas over a surface boundary (trough/dryline) initiating severe convection up to supercells through the high plains. Although most of this storm complex should be stay well in the Southern up through Central High Plains a few of these elevated storms could stray into parts of far northwest Oklahoma which could produce strong to severe wind gusts and small hail.

SHORT TERM

(Tuesday night through Thursday night) Issued at 116 AM CDT Tue Jun 30 2026

Expecting any Tuesday evening storm activity across northwest Oklahoma to be decaying overnight. Wednesday & Thursday are near repeaters of Tuesday with another potential storm complex developing late in the Southern through Central High Plains late Wednesday although some model differences for late Thursday with only the ECMWF as the stormy solution. For now our western (as well as our entire) CWA remain POP-free for both days. Some of our Oklahoma counties will come very close to tying or even breaking their warmest low temperature daily record. Not expecting to be near breaking any temperature records south of the Red River across our Texas counties.

LONG TERM

(Friday through Monday) Issued at 116 AM CDT Tue Jun 30 2026

Our weather pattern does start to change on Friday as the upper troughing breaks down across the U.S. Southwest with ridging building and expanding eastward over much of the entire southern half of the country. The increasing pressure heights on Friday will start two days of excessive heating going into Independence Day (Saturday). As a result will see high temperatures rise to triple digits with heat indices exceeding 105 degrees especially on Saturday which could prompt our next Heat Advisory. By Saturday night could see a cold front push down at least through the Central Plains interacting with weak troughing in the ridging. This may initiate storm activity in Kansas going into northern Oklahoma Saturday evening and our entire Oklahoma/Texas area Saturday night into Sunday and Monday. The potential rain/storms Sunday & Monday should bring some temperature relief from the 2-day excessive heating trend with afternoon highs below triple digits.

AVIATION

(06Z TAFS) Issued at 1053 PM CDT Mon Jun 29 2026

VFR conditions are expected to continue through the TAF period.

Breezy southerly winds will continue with a modest (~50 knot) low-level jet resulting in low-level wind shear (LLWS) tonight.

A few showers/storms are ongoing in southwest Oklahoma and isolated to scattered thunderstorms in the Texas panhandle will approach western Oklahoma once again tomorrow evening. However, these thunderstorms will likely dissipate before they impact KWWR and KCSM both tonight and tomorrow night. Given the low probability, TSRA were not included in the TAFs at either terminal.
