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 May 17, 2:52 AM CDT, 2 hours 32 minutes earlier.
Area forecast discussion, May 17, 2:52 AM CDT, 2 hours 32 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 252 AM CDT Wed May 17 2017 .DISCUSSION... Band of showers/thunderstorms continues to make progress into the eastern fringes of our forecast area early this morning. Leading edge of convection has produced sporadic 40-55 mph gusts...although expect a gradual decrease in storm intensity over the next several hours as convection moves into more stable air. This activity will weaken further by late morning into far eastern OK/western AR...with only slight chance PoPs remaining in the afternoon forecast across western AR. South to southwest winds will push wind advisory criteria across parts of northeast OK...although will hold off on any headlines at this time. Day shift can monitor morning conditions and issue if necessary. The dryline should temporarily move through a large portion of eastern OK this afternoon before retreating west overnight as breezy south winds persist. Thursday should remain convection free as the dryline retreats farther west to near the TX panhandle/western OK border. Storms are expected to develop in this area by late afternoon/early evening...with upscale growth into the overnight hours as storms move into parts of eastern OK. Severe weather will be a possibility with this activity. The active pattern will continue into late week as a secondary upper wave swings around the primary central Rockies cyclone. This will result in yet another round of dryline convection moving east into the area late Friday into Friday night...with storms lingering into at least Saturday night before the synoptic front finally shifts southeast of the region. Severe weather along with heavy rainfall will be possible for much of the area. && .PRELIMINARY POINT TEMPS/POPS...
