The episode as NWS OUN wrote it up.
Despite a rather volatile airmass for severe weather across Oklahoma and north Texas on the 26th, misaligned synoptic features (i.e., neutral-to-rising mid-level heights) and remnant convective inhibition limited the overall number/coverage of thunderstorms during the evening. The most significant storm was a slow-moving supercell storm near and north of Wichita Falls, Texas. This thunderstorm produced large to very large hail and yielded a pair of left-moving supercells that went on to produce hail into portions of adjacent southern Oklahoma. This included confirmations of baseball-size hail in areas east of Lawton, Oklahoma.

NWS Norman, OK wrote its last area forecast discussion before the first event at Apr 26, 4:17 PM CST, 36 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Norman OK 517 PM CDT Sun Apr 26 2026 ...New AVIATION... .KEY MESSAGES... Updated at 514 PM CDT Sun Apr 26 2026 - Conditional risk for severe storms this afternoon and evening. If storms occur, all severe hazards would be possible including very large hail, damaging wind gusts, and a low tornado risk. - Drier air moves in Monday, with elevated to near critical fire weather expected across western/northwestern OK. - Low storm chances across southeast OK Tuesday, better chances for showers and storms over the entire area Thursday into Friday. && .NEAR TERM... (Today and tonight) Issued at 1135 AM CDT Sun Apr 26 2026 A conditional severe risk with a complex set of meteorological features is in place for today. Warm air advection has been ongoing and has already produced a few weak storms in north central Oklahoma this morning. Most of this isolated to scattered activity is expected to remain weak, though a strong storm or two can't be ruled out as we get into the afternoon hours. Later this afternoon and evening, we'll see the potential for convection to focus in two main areas: along a dryline roughly near and west of highway 81 (mainly southern Oklahoma and north Texas), and in the warm front zone across northern Oklahoma. Dryline convection will be more dependent on daytime heating with upper support being quite distant. CAMs are inconsistent on whether there's enough forcing to get storms to form, but any storms that do form will have a risk for large to very large hail and tornadoes. The warm front may be a later show as the upper wave approaches. CAMs depict storms starting in northwest Oklahoma and moving eastward across the state. Again, there is some uncertainty in getting storms to form, but the chances are higher in this region. Similarly, large to very large hail and tornadoes are both potential hazards. The tornado risk may be most acute when the low level jet starts to ramp up this evening. This jet will also help storms persist into the overnight period. Day && .SHORT TERM... (Monday through Tuesday night) Issued at 1135 AM CDT Sun Apr 26 2026 Southwesterly / westerly low level flow will bring in much drier air on Monday, setting us up for elevated to near-critical fire weather across western portions of the forecast area. The low level thermal ridge is expected to set up across southwest Oklahoma into central Oklahoma, putting it out of sync with the highest ERCs in northwest Oklahoma. There will likely be some overlap to watch, but most areas outside of northwest Oklahoma have seen enough green-up to mitigate fire danger. Winds will be breezy (especially along the thermal ridge) and highs will be in the 80s and 90s. A weak cold front will enter northern Oklahoma Monday night, then stall roughly halfway across the forecast area on Tuesday (though there is still some uncertainty in this frontal position). This will provide a focus for showers and storms along and south of the front in south central Oklahoma Tuesday afternoon and evening. The front will also set us up with a temperature gradient ranging from highs in the lower 70s in northern Oklahoma to the low 90s in north Texas. Day && .LONG TERM... (Wednesday through Saturday) Issued at 200 AM CDT Sun Apr 26 2026 Dry/cooler conditions are forecast across the area on Wednesday as low amplitude ridging will be in place over the southern Plains ahead of another shortwave across the southwest US. Shower and thunderstorm chances will then increase Thursday and especially Friday as the wave draws moisture northward over the residual frontal zone. Extensive warm air advection and isentropic ascent is forecast could lead to heavy rainfall across portions of the area (currently most favored across southern OK and western north TX). The severe risk appears more uncertain and will depend on whether or not sufficient instability can return northward. Highs during this period will be below normal, mainly in the 60s to low 70s through the weekend. Ware && .AVIATION... (00Z TAFS) Issued at 514 PM CDT Sun Apr 26 2026 Showers and a few thunderstorms may impact portions of the area this afternoon and evening, primarily across western north Texas and southwestern Oklahoma, and northern Oklahoma. There is a little uncertainty into impacting TAF sites, but it may be close. LLWS will affect most TAF sites late tonight into early Monday morning. && .PRELIMINARY POINT TEMPS/POPS...
