The local office's own words before this special weather statement went out, 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 this special weather statement went out at Jul 14, 2:50 PM CDT, 2 hours 57 minutes earlier.
Area forecast discussion, Jul 14, 2:50 PM CDT, 2 hours 57 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 250 PM CDT Fri Jul 14 2017 .DISCUSSION... Residual cloud cover from the morning thunderstorm complex has helped to keep temperatures below normal across a good chunk of northeast Oklahoma and western Arkansas this afternoon. An outflow boundary produced by the complex stretches across southeast Oklahoma and into west central and southwest Arkansas. The weak and somewhat diffuse synoptic cool front remains north of the Oklahoma and Arkansas borders this afternoon but will move toward the south and west overnight and into tomorrow. Additional thunderstorms should develop along the front late tonight and early tomorrow morning, with locally heavy rain existing with the stronger, slow moving storms. The main thunderstorm axis will shift southward into tomorrow night and Sunday, as the front sags through the area. While widely scattered afternoon thunderstorms will be possible into early next week, especially in the higher terrain areas, the overall coverage should be low enough after Sunday to keep below mentionable levels for now. Behind the cool front, temperatures will be close to normal tomorrow and maybe a degree or two warmer for Sunday. Ridging will build back into the region next week, with above normal temperatures returning and likely peaking toward the mid to latter part of the work week. && .PRELIMINARY POINT TEMPS/POPS...
