KEY MESSAGES

Updated at 629 AM CDT Wed May 13 2026

- Very low rain chances tonight along the Kansas and Missouri borders.

- Low chances of showers and thunderstorms for the weekend, with a limited severe weather potential during the period.

- Temperatures near to above mid May normals forecast through the weekend.

SHORT TERM

(Through Wednesday) Issued at 1112 PM CDT Tue May 12 2026

A slow-moving front continues to sag southward toward the area late this evening. There have been a couple of recent attempts at shower development near the boundary across parts of Kansas, similar to that consistently depicted in this evening/s HRRR runs. Will keep POPs early Thursday morning just below mentionable levels in most spots but have increased them to slight chance across the far northeast corner of Oklahoma given the aforementioned HRRR data. Overall, it should not be a big deal. Cloud cover that has developed across southeastern Kansas ahead of the front will continue to sag southward with time and with the movement of the front, with periods of partly to mostly cloudy skies into Wednesday. About a 10 degree difference in afternoon temperatures remains expected from northern parts of the forecast area to areas near the Red River, given the expected frontal passage timing.

LONG TERM

(Wednesday Night through Tuesday) Issued at 1112 PM CDT Tue May 12 2026

The front will begin to move back to the north and northeast Wednesday night into Thursday, with warm advection shower and thunderstorm potential focusing across northeast Oklahoma and northwest Arkansas toward and just after daybreak Thursday. Gusty southerly winds will develop Thursday, spurring good moisture return into mainly eastern Oklahoma by Thursday night. A disturbance along the Kansas border Thursday night into early Friday may spark a few showers and thunderstorms in northern Oklahoma, but current expectations are for those to remain west of the forecast area, with a mention left out of the forecast for now. Friday will be another breezy and warm day. The NBM initialization for highs on Friday is more reasonable than in past days, given the expectations for cloud cover, and as such will not be modified for this forecast. Low chances for thunderstorms will exist Friday evening across the northwest fringes of the forecast area with better potential for storms that develop to the west, in response to another disturbance, to move eastward into parts of mainly northeast Oklahoma and northwest Arkansas through Saturday morning. The well above normal temperatures from late this week will continue into Saturday and Sunday, possibly into Monday, although that is not a given.

A stronger storm system remains on track to impact the area early next week, dragging a cold front southeastward as the energy ejects into the Central Plains. A greater chance for showers and thunderstorms will focus along the front that looks to linger across the region into at least the middle of next week. Heavy rain potential will be a focus during the period given the amount of precipitable water forecast to be near climatological maxes. Severe storm potential will also exist.
