KEY MESSAGES

Issued at 1210 AM CDT Fri Apr 24 2026

- Another round of potentially severe weather will occur south of I-40 this afternoon and evening. - Additional severe storms are expected Saturday afternoon and evening. Severe storms may also occur Sunday but confidence is lower.

- Drier weather is expected to briefly return to the area Monday into Tuesday before an active pattern resumes.

SHORT TERM

(Through tonight ) Issued at 1207 PM CDT Fri Apr 24 2026

A west-to-east boundary is present across the middle of the forecast area. It is in the process of merging a weak cold front from the north with existing outflow from previous convection. Scattered showers and thunderstorms will continue to develop near the boundary. Daytime heating and somewhat deeper moisture will result in a reinvigoration of storms mid to late afternoon south of the boundary. Most CAMs agree that scattered supercell formation is likely. Shear in the boundary layer looks relatively low, and the boundary layer will have decent vertical depth, so hail should dominate initially. Hail up to the size of tennis balls may occur. With that said, isolated tornadoes and strong wind remain possible. Over time, storms will consolidate into a line as they move southeast, with wind and perhaps QLCS tornadoes becoming more likely into the late evening. Wind gusts of up to 70 mph may occur.

Areas north of the boundary will see a partly sunny day with some northerly breezes. Overnight, tonight temperatures will cool more effectively than last night, with 50s expected for most spots. Rain chances will be very low overnight.

LONG TERM

(Tomorrow through Friday) Issued at 1207 PM CDT Fri Apr 24 2026

Saturday morning will see the old boundary surge back north as a warm front. CAMs disagree on how far north it will go, but this is critically important for identifying where the severe potential will maximize. Currently the most likely corridor appears to be somewhere between McAlester and Henryetta, angling east-southeast into west- central Arkansas. But some guidance pushes this corridor further north. Areas near and just north of the boundary will see the best severe weather potential. CAMs are in surprisingly good agreement on what will happen even if they aren't sure where it will happen, which is multiple discrete right moving supercells capable of all severe hazards, but very large hail in particular. As typically occurs, these cells will favor congealing into an MCS over time, with more of a wind and rain threat later on.

Sunday will feature a very unstable and sheared atmosphere with the dry line west of the area and warm sector overhead. The question will be convective initiation. If storms can get going, the atmosphere will support the potential for significant severe weather. But as of now, some models show storm activity and some do not. Those that do show it being most likely near the OK-KS-MO triple point, and propagating south to southeast from there. This will need to be watched closely, but ultimately likely depends on what happens on Saturday. Monday will be warm with just a slight chance of a few showers or storms before the cold front moves through. The best chance of precipitation will be the higher terrain in the eastern half of the forecast area.

Behind the front there will be a temporary reprieve from storm activity, but rain chances will return to portions of the area by Tuesday afternoon (mostly the southeast half of the forecast area). Slight chances of showers and storms continue into Wednesday and beyond. High temperatures will fall into the 70s beyond the front with lows in the 50s.

AVIATION

(00Z TAFS) Issued at 635 PM CDT Fri Apr 24 2026

Additional thunderstorm impacts will remain possible at FSM/MLC for the first two to three hours of the valid TAF period, although the greatest potential will shift south and east of those sites prior to 00Z. Some improvement in ceilings should occur through the evening, except at MLC/FSM, with potential for MVFR to locally, IFR fog and another round of MVFR ceilings late tonight into tomorrow morning. Wind speeds should increase from the south and east tomorrow afternoon, with the E OK sites most likely to see additional thunderstorm impacts prior to the end of the TAF period. W AR sites will see increased potential for these impacts after the valid TAF period.
