The episode as NWS TSA wrote it up.
Strong to severe thunderstorms developed across southeastern Kansas, northeastern Oklahoma, and northwestern Arkansas during the late afternoon of the 14th, as a cold front approached the area. The thunderstorms moved east across the region through the evening hours. The strongest storms produced damaging wind gusts.
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 Nov 14, 9:23 PM CST, 2 minutes earlier.
Area Forecast Discussion National Weather Service Tulsa OK 923 PM CST Sat Nov 14 2020 .DISCUSSION... Scattered low-topped supercells continue over parts of western Arkansas near the nose of 700mb jet in unstable pre-frontal environment, and will continue to pose a severe threat for a couple more hours. Cold front currently located near Checotah to Gravette and will continue to sweep through the remainder of the area by Midnight. Front is forcing a broken line of storms, however updrafts quickly being undercut and as such, these storms pose little severe threat. Gusty northwest winds immediately in the wake of the front have been enhanced by convective cells immediately behind it, with brief gusts in the 40-45 mph range noted. Severe threat will end once the front clears the forecast area. Additional updates will mainly be to clear more counties from tornado watch behind the front...and have also upped wind speeds behind the front for tonight. && .PREV DISCUSSION... /Issued 506 PM CST Sat Nov 14 2020/ AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. The main concern with the potential for thunderstorms to impact the western Arkansas sites through 06z as a cold front sweeps through the region rather quickly. After 6z... the gusty northwest winds will be concern as ceilings clear out. PREV DISCUSSION... /Issued 145 PM CST Sat Nov 14 2020/ DISCUSSION... Primary concerns will be the convection trend the remainder of the afternoon and into the evening. Current visible satl imagery shows the back edge of the clouds over the part western parts of the forecast area, with considerable breaks in the overcast noted across parts of southeast into far eastern OK. If these trends continue, then afternoon instability may a bit higher than earlier anticipated. Recent runs of the HRRR appear to latch on to this idea, with scattered pre-frontal convection developing along OK/AR border around 21-22Z. A few of these storms could become severe, with forecast wind fields showing the potential for rotating storms. This activity would likely shift east of the area by early evening, although expect additional development as the cold front enters northwest AR around 03-04Z. This activity may pose a small severe threat, with storms quickly exiting the area by midnight. Will keep an eye on wind gusts over the next few hours, but anticipate leaving the current Wind Advisory as is. Sunday will be seasonally cool and dry, although temperatures will bounce back to above normal readings next week as mid-level heights rise. Went a touch above NBM guidance, with afternoon temps likely pushing the mid 70s in some spots by Thursday and possibly into Friday. Shower and thunderstorm chances look to increase next weekend as the upper flow becomes southwesterly and a cold front approaches. && .PRELIMINARY POINT TEMPS/POPS...
