KEY MESSAGES

Updated at 459 AM CDT Wed Apr 29 2026

- A widespread round of rain is expected Thursday into Friday, but could be limited to locations near and south of I-40.

- Severe storms look unlikely over the next week.

- Cool temperatures are expected through Saturday, then warming.

NEAR TERM

(Through Wednesday) Issued at 206 AM CDT Wed Apr 29 2026

For the first time in a week, we do not have a risk of severe storms somewhere over the forecast area today. The cold front has pushed south into central Texas and has pushed any instability away from the area. A surface ridge is our main weather story today as a 1023 mb high shifts from Nebraska into northern Kansas this morning. High temperatures today will generally be 5 to 10 degrees below average for the date. Zonal flow aloft continues to push enough upper- level moisture over the area for areas of cirrus today.

SHORT TERM

(Wednesday night through Friday night) Issued at 206 AM CDT Wed Apr 29 2026

A upper-level storm system over the Pacific around 30N/130W is projected to open up as it approaches the Baja California coast on Thursday and then continue to move east toward the southern Plains Friday. Ahead of this system, some isentropic lift will develop across Texas and will potentially reach into southern Oklahoma on Thursday, although the models are generally seeming to back off on how far north or how widespread this convection will be into our forecast area. Showers and thunderstorm chances will persist into Friday as the upper-level storm system moves through the southern Plains, although again there is a question on how far north the convection will spread with the primary lift with this storm system primarily to the south in Texas. Farther northwest, easterly upslope low-level flow will aid in shower development across the New Mexico and west Texas High Plains, but it is unclear how much of that convection will move into western Oklahoma.

Despite high precipitation chances (primarily south), the front that moved through yesterday has displaced instability to the south, so severe weather is unlikely Thursday/Friday.

Clouds and precipitation associated with the approaching storm system and the continued cool post-frontal airmass will keep temperatures cool through the remainder of the week.

LONG TERM

(Saturday through Tuesday) Issued at 206 AM CDT Wed Apr 29 2026

The storm system moves east of the forecast area Friday night/Saturday with upper ridging developing in the western United States bringing a northwesterly flow aloft to the area this weekend. Saturday is expected to be cool again, but then southwesterly low-level flow redevelops by Sunday and temperatures begin to warm again. This weather pattern is a generally dry pattern with no precipitation chances through at least Monday.

AVIATION

(12Z TAFS) Issued at 459 AM CDT Wed Apr 29 2026

Northeast to east winds will persist today, becoming a bit gustier during the mid morning to late afternoon period. VFR conditions are expected to prevail outside of a low chance for MVFR ceilings at KDUA for a few hours this morning.
