The episode as NWS TSA wrote it up.
Slow moving showers and thunderstorms formed along a stalled frontal boundary across far northeast Oklahoma into far northwest Arkansas. This activity resulted in a prolonged period of heavy rainfall across the area and some localized flooding.
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 Jul 8, 10:50 PM CST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Tulsa OK 1150 PM CDT FRI JUL 8 2016 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Widespread convection ongoing across NW AR will persist with additional development possible across NE OK early this morning. Eventually higher storm chances will shift southward before coverage becomes more scattered by afternoon. Outside of any storms VFR conditions are expected to prevail. && .PREV DISCUSSION... /Issued 950 PM CDT FRI JUL 8 2016/ DISCUSSION... The earlier convection across eastern OK has weakened, while area of stratiform rain with isolated thunder continues to expand toward northeast. Subtle boundaries will remain in place overnight with continued chance of thunderstorm re-development. Model guidance continues to struggle with placement of additional storms overnight, though current trends point to area along and just south of i44 in the very near term. Only adjustments to POP forecast will be to incorporate latest short term trends. Updated products out shortly. PREV DISCUSSION... /Issued 628 PM CDT FRI JUL 8 2016/ AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Convection ongoing across Central OK and gradually spreading eastward will initially avoid terminal sites. Additional storms are likely later tonight and primarily impact NE OK into far NW AR through mid morning. Thereafter storm chances continue through the remainder of the day with any residual boundaries serving as a focus. Outside of convection VFR conditions are expected. PREV DISCUSSION... /Issued 220 PM CDT FRI JUL 8 2016/ DISCUSSION... The morning complex of storms has lifted into the MO Ozarks as of early afternoon. Remnant cloud cover and mid level clouds/showers/storms remain across NE OK and NW AR. Afternoon storms would be most likely along any residual boundaries to the south of the cloud shield. Looking toward the forecast for tonight, the hard to find synoptic front lies roughly from the MO Ozarks back along the KS border to NW OK. Redevelopment of storms is most likely near this boundary, with the latest operational HRRR and larger scale ECMWF suggesting another tstorm cluster will evolve across N OK tonight and will eventually shift into NW AR Saturday morning. Will keep the highest pops across NE OK/NW AR on Saturday and Saturday night near the residual synoptic front. Storm chances decrease Sunday as the boundary washes out and plan to go dry by Sunday night. Will plan to go dry for early to middle part of next week with some gradually rising mid level heights, aside from some small pops tuesday night near a stalling boundary to our NW. Another boundary will bring tstorm potential again for the latter part of the week as mid level ridging intensifies over the Desert Southwest. I made very little adjustment to the going temps. Relatively cooler temps this weekend, followed by a warm up early to mid part of next week. A cooling trend is possible toward the end of next week with the next front.
