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 Jun 30, 2:08 AM CDT, 3 hours 39 minutes earlier.
Area forecast discussion, Jun 30, 2:08 AM CDT, 3 hours 39 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 208 AM CDT Fri Jun 30 2017 .DISCUSSION... Strong to severe MCS continues to push southeast through north- central Oklahoma and southeast Kansas. This activity will likely move into northeast Oklahoma before sunrise with the threat for damaging winds/marginal hail. Overall severe threat should begin to diminish east of highway 75 and especially southeast of I-44 as storms move into a more stable airmass with weakening wind fields aloft. Morning convection will likely produce an outflow boundary that will provide the focus for additional strong to severe thunderstorms this afternoon as atmosphere becomes moderately unstable with surface heating. One or more thunderstorm clusters will likely push south into southeast Oklahoma/west-central Arkansas tonight with mainly a heavy rain threat, although a few marginally severe storms could remain possible. Frontal boundary stalls across southeast Oklahoma/west-central Arkansas with additional shower/thunderstorm development along stalled front Saturday and possibly into Saturday night although precipitation coverage should be less. Another weak upper wave will move into the Central Plains Monday into Tuesday. Lingering precipitation chances will continue across far northeast Oklahoma and northwest Arkansas, however main thunderstorm activity is expected to remain north of area in association with stronger forcing. Scattered showers/thunderstorms will remain possible through the remainder of the work week as another weak front stalls across the area. && .PRELIMINARY POINT TEMPS/POPS...
