On the 8th, modest northwesterly flow aloft, including an embedded upper-level impulse, was present across the Southern Plains. This enhanced flow and lift contributed to scattered supercell thunderstorms from southern Kansas into portions of northern Oklahoma and the adjacent northeast Texas Panhandle.

The episode as NWS OUN wrote it up.
On the 8th, modest northwesterly flow aloft, including an embedded upper-level impulse, was present across the Southern Plains. This enhanced flow and lift contributed to scattered supercell thunderstorms from southern Kansas into portions of northern Oklahoma and the adjacent northeast Texas Panhandle. In addition to reports of large hail and isolated wind damage, a well-documented tornado occurred in northern Harper County, north of the community of Buffalo, Oklahoma.

NWS Norman, OK wrote its last area forecast discussion before the first event at Sep 8, 4:13 PM CST, 44 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Norman OK 513 PM CDT Mon Sep 8 2025 ...New AVIATION... .KEY MESSAGES... Updated at 509 PM CDT Mon Sep 8 2025 - Strong to severe thunderstorms are possible this afternoon and evening, primarily across western Oklahoma. - Mild weather continues today with above-normal temperatures likely by mid to late week. && .NEAR TERM... (Rest of today and tonight) Issued at 1236 PM CDT Mon Sep 8 2025 Thunderstorms have all but diminish across northwest/west central Oklahoma this morning with convective debris clouds remaining. These should gradually thin through the afternoon. Elsewhere, low clouds across parts of the Texas Panhandle and southwestern Oklahoma/western north Texas have scattered into more of a Cu structure. Convective-allowing models (CAMs) have trended with less coverage of storms this afternoon and evening near northwest/west central Oklahoma. However, water vapor imagery shows a well defined shortwave trough moving into northwestern Kansas with some cloud enhancement ahead of the feature. Lift associated with the approaching disturbance and daytime heating should result in at least isolated storms by late afternoon/early evening. Perhaps a better chance of boundary-layer convection will develop across the Panhandles within weak convergent flow. These storms should take a while to enter western Oklahoma. If showers/storms form over northern Oklahoma this afternoon they should be more elevated. With the effective shear around 35+ knots, and CAPE (1500-200 J/kg) this will support strong to severe storms with large hail and damaging winds. A low-level jet is expected to develop by late evening/overnight. The stronger winds tonight should be positioned farther east than last night and more veered. Although the mid-level winds will remain weak and not as westerly, isolated/widely scattered elevated showers and storms are possible. This may occur over parts of north central/central Oklahoma. It also appears a much better setup for organized convection will be to our north in parts of Kansas. However, models are not handling the ongoing convection in central Kansas very well. Given the veered jet and northwest flow, some of this activity may try and build into north central Oklahoma during the morning. There are also indications that a weak disturbance may approach western Oklahoma late tonight into early Tuesday. && .SHORT TERM... (Tuesday through Wednesday night) Issued at 1236 PM CDT Mon Sep 8 2025 Isolated showers and storms may be ongoing across mainly north central/central/far western Oklahoma early Tuesday morning. If another organized area of convection develops in Kansas will need to see if this activity may develop over or move into north central Oklahoma during the morning/early afternoon. Although the pattern will become unfavorable for storms by late Wednesday/Thursday (upper ridge builds over the southern Plains), another weak disturbance will result in low chances of storms Tuesday evening into Wednesday morning. These storms should mainly occur across western/northern Oklahoma. && .LONG TERM... (Thursday through Sunday) Issued at 210 AM CDT Mon Sep 8 2025 The mid-level ridge is forecast to remain entrenched across the Southern Plains through at least Saturday, which will likely result in continued above-normal temperatures and minimal rain chances. The probabilistic temperature forecast (derived from an ensemble of bias-corrected models) indicates a very high chance of above- normal temperatures given even the 10th percentile (the colder end of guidance) has slightly above-normal temperatures Thursday through Saturday. High temperatures will likely range from the upper 80s to mid 90s deg F. By late Saturday into Sunday, the mid-level ridge may weaken as a trough lifts into the Plains. As a result, there is at least a low chance of showers and thunderstorms the second half of the weekend. Mahale && .AVIATION... (00Z TAFS) Issued at 509 PM CDT Mon Sep 8 2025 A line of discrete severe thunderstorms have developed in southern Kansas and are propogating slowly to the south towards northern Oklahoma. Added TEMPO groups for storms at WWR and PNC this evening. Large to very large hail is possible for storms over northwest Oklahoma over the next few hours, with severe storms expected to diminish by midnight. Otherwise, low chances for showers/storms continue into Tuesday evening with southerly winds. Thompson && .PRELIMINARY POINT TEMPS/POPS...
