KEY MESSAGES

Updated at 127 PM CDT Tue May 26 2026

- Showers/thunderstorms continue to affect the area into tonight. A few strong to marginally severe storms are possible.

- Daily rain and storm chances will continue through next weekend across portions of the area. Strong to severe storms may be possible.

NEAR TERM

(Rest of today and tonight) Issued at 127 PM CDT Tue May 26 2026

There are two main features along with sfc heating that are causing scattered showers/storms across the fa today. One feature is the closed low that was in TX yesterday is now lifting northward across portions of eastern OK/AR. The other feature is a shortwave moving into the southern Plains providing large scale ascent to parts of the region.

A band of showers/storms associated with the shortwave has been moving across parts of west TX all morning. This band is expected to move into SW/W portions of the fa this afternoon and continuing to move across parts of the area tonight as the shortwave continues to move across the region and ascent spreads eastward. Meanwhile, in parts of OK and western north TX, scattered showers/storms have developed this morning into early afternoon. This activity is expected to continue into early evening with some decrease in coverage possible with the loss of heating and the main focus of showers/storms being closer to the shortwave. Some of the storms could become strong to marginally severe with hail and strong winds. Locally heavy rain will also be a concern, especially in parts of western north TX and southwest OK.

SHORT TERM

(Wednesday through Thursday night) Issued at 127 PM CDT Tue May 26 2026

The previously mentioned shortwave will continue to affect the area which will continue the chance for showers/storms Wednesday. Enough instability could develop that some of the storms become strong to severe Wednesday with large hail the main concern. Locally heavy rain will also continue to be a concern. However, there is also the potential for a risk for funnel clouds/landspouts to maybe develop across portions of the area Wednesday as well. The risk for such occurrences will be focused near a weak surface low, currently forecast to lift northward near or just west of the TX/OK state line through the day. As low level instability develops in conjunction with this area of mid/low-level spin, conditions could become favorable for funnel cloud and/or landspout development. Of course where this could develop will be dependent on the track of the low.

Showers/storms will continue to be possible into Thursday. Strong storms and locally heavy rain will remain concerns with hail and gusty winds possible.

The cloud cover and rain will lead to cooler temperatures Wednesday compared to today with highs in 70s to low 80s. Lingering cloud cover and rain will maintain the below average temperatures into Thursday with highs once again in the 70s to low 80s.

LONG TERM

(Friday through Monday) Issued at 146 AM CDT Tue May 26 2026

Another weak shortwave will move across the southern Plains Friday, which will provide enough lift for thunderstorms late Friday into Saturday (from west to east). Beyond Friday, there is a little more uncertainty regarding the pattern across the southern Plains. The larger scale trough across the western US is expected to lift into northern portions of the US. Across our area, there may be weak mid- level perturbations which will promote additional thunderstorm chances through the weekend. Other model solutions would suggest mid- level ridging, which promotes dry and warmer weather. For now, will keep the mention of thunderstorms through the weekend until models are in better agreement.

AVIATION

(18Z TAFS) Issued at 1200 PM CDT Tue May 26 2026

While most terminals will maintain VFR category into Tuesday evening, widely scattered diurnal convection will offer limited (~30%) potential for category reductions through sunset. By the mid- evening into early Wednesday morning, a more coherent band/arc of rain and storms will move from southwest-to-northeast across the area, introducing a more likely rainy/stormy period.

Low stratus is also expected to emerge during the predawn hours on Wednesday, with most likely IFR cigs expected at KWWR/KLAW/KCSM/KOKC/KOUN. At least limited rain and storm coverage will continue towards the end of the period across northern Oklahoma as well.

Safe travels!
