The episode as NWS TSA wrote it up.
Scattered, high-based showers and isolated thunderstorms developed across portions of northeastern Oklahoma during the late evening of the 15th and early morning of the 16th, as an upper level disturbance approached the region. Isolated damaging wind occurred with a few of the thunderstorms.
Strong non-thunderstorm wind gusts occurred with some of the showers. The ASOS at the Tulsa International Airport measured wind gusts up to 69 mph, and large tree limbs were snapped across Tulsa County by non-thunderstorm wind.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tulsa, OK wrote its last area forecast discussion before the first event at May 15, 10:34 PM CST, 21 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Tulsa OK 1134 PM CDT Fri May 15 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1133 PM CDT Fri May 15 2026 -Low thunderstorm chances tonight through Sunday. Limited severe risk Sunday afternoon and evening. - A more active weather pattern is expected early next week including the risk of higher-end severe weather and heavy rainfall. && .SHORT TERM... (Through Saturday) Issued at 1133 PM CDT Fri May 15 2026 Elevated storms have decreased in coverage but winds remain gusty near and north of where the activity has been weakening. A short- term wind advisory will be issued to cover areas along and north of I-44 for the gusty winds beneath the decaying showers/storms. This activity has been occurring ahead of a shortwave trough that shows up on WV imagery to our west. An MCS is weakening as it progresses east near the Red River and vicinity, but is in the process of leaving an MCV behind. This MCV is expected to track across SE OK and NW AR during the morning and midday hours on Saturday, in tandem with the broader shortwave trough. Given the steep lapse rates aloft as the previous shift mentioned, this forcing will result in other round of elevated/high-based showers and isolated storms moving east across the region tonight into Saturday. Once this wave/MCV passes Saturday afternoon, there will be a lull in activity. Chances of storm development on the dryline out west are minimal Saturday afternoon. Lacy && .LONG TERM... (Saturday Night through Friday) Issued at 1133 PM CDT Fri May 15 2026 Aside from a low chance of showers from the ArkLaTex up into NW AR in the deep-layer moist plume, the focus on Sunday will continue to be to the west of the forecast area on the dryline. Isolated storm development is possible, with any storms that survive into eastern OK carrying a higher-end severe risk. A strong upper trough is expected to emerge into the central Plains Monday. By Monday afternoon, a sharp dryline will lie over western OK extending north to a triple point over KS where it intersects a southeastward-surging cold front. There will be a more pronounced increase in low level moisture east of the dryline with dewpoints climbing into the 70s. There is some disagreement on how capped the warm sector will be, with the EC showing some capping and the GFS showing an uncapped airmass. This could affect warm sector quality. With at least a glancing influence from the ejecting shortwave trough, storms are expected to develop off the dryline and will carry the highest severe threat potential for this forecast into eastern OK Monday afternoon and evening. The models today continue with a more aggressive southward push to the cold front. Current progs have the front sliding south across the forecast area Monday night into Tuesday. The front would focus storms and some severe threat as well as it moves through. Depending on the speed of the front, there could be some severe weather and locally heavy rainfall potential Tuesday afternoon and evening over SE OK and NW AR. While some chance for showers and storms will persist over the region through Thursday in advance of a shortwave trough, the greater severe weather potential will shift south of the region with the front. Rain/storm chances will persist through the end of next week as moisture returns, but we lose the flow aloft, thus severe potential will be limited. Lacy && .AVIATION... (00Z TAFS) Issued at 641 PM CDT Fri May 15 2026 Isolated to scattered showers and sprinkles (with occasional lightning) continue to stream across eastern OK and northwest AR early this evening. These widespread spotty and brief showers will persist overnight and into tomorrow morning. Hi-res model data show radar echos intensifying some around midnight and continuing through daybreak. Included some PROB30 groups for low thunder chances at KMLC, KXNA, KROG, KFYV, and KFSM when the best chances of thunder will occur, though timing confidence is fairly low. Regardless, aviation impacts should be low to none through the period. Mid and high level clouds will continue to prevail through the forecast period. A robust LLJ will create LLWS for most TAF sites. Overall, VFR is expected to prevail through the period. Mejia && .PRELIMINARY POINT TEMPS/POPS...
