NWS Tulsa, OK wrote its last area forecast discussion before the first event at Aug 3, 5:22 PM CST, 8 minutes earlier.
Area Forecast Discussion National Weather Service Tulsa OK 622 PM CDT Thu Aug 3 2017 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Band of showers and thunderstorms will continue to drop south through northeast OK and northwest AR this evening before weakening some later this afternoon. Expect areas of MVFR conditions along with gusty downburst winds. May also see some redevelopment of storms later tonight...especially across northeast OK. && .PREV DISCUSSION... /Issued 259 PM CDT Thu Aug 3 2017/ DISCUSSION... Scattered showers and thunderstorms have developed this afternoon in the vicinity of a cold front that is currently moving across southeast Kansas. Scattered showers and thunderstorms are expected to spread into northeast Oklahoma and northwest Arkansas late this afternoon and evening as the cold front pushes to the south. There is the potential for a few of these storms to become strong to marginally severe with gusty winds and hail possible. Scattered showers and thunderstorms will continue to be possible through the night and into Friday in the vicinity of the front as it moves to near the Red River Friday afternoon. After a quite Friday evening across the region, the chances of showers and thunderstorms return late Friday night with isentropic lift occurring to the north of the surface boundary as it retreats to the north as a warm front. The scattered showers and thunderstorms will continue on Saturday north of the warm front as it continues to move north. There is a chance that the POPs are overdone for Saturday depending on how far north the warm front advances. The ECMWF and NAM both suggest that the front surges north of the area on Saturday and most of the area stays dry. The chances of showers and thunderstorms really ramp up Saturday night into Sunday as an MCS and associated cold front move into the region. Some of the storms during this time-frame will be strong to severe with strong gusty winds and large hail the concern. Locally heavy rain will also be possible The threat for showers and thunderstorms will continue next week as the front stalls near the Red River early in the week and slowly returns north across the region as we move into the middle part of next week. Additional heavy rains could be possible during this time especially across southeast Oklahoma. Temperatures are expected to be below normal for much of the forecast period. Again, temperatures on Saturday could be several degrees warmer than forecast depending on how far the warm front surges during the day on Saturday. && .PRELIMINARY POINT TEMPS/POPS...

SEVERE THUNDERSTORM. RISK...Isolated. AREA...Northeast Oklahoma and far Northwest Arkansas. ONSET...Ongoing. DISCUSSION... Thunderstorms have developed over parts of Northeast Oklahoma late this afternoon ahead of a cold front expected to move into the region this evening and overnight tonight. Thunderstorm chances will spread southward across Northeast Oklahoma and Northwest Arkansas tonight as the frontal boundary pushes toward Interstate 40 by early Friday morning. Some of these storms could produce strong to marginally severe wind gusts of 60 mph and also some small size hail through the evening hours. Severe potentials should begin to decrease late this evening and overnight tonight. Across Southeast Oklahoma...isolated thunderstorm chances will remain possible mainly over the higher terrain locations into the evening hours before the loss of daytime heating. Additional thunderstorm chances will be possible overnight as the cold front moves toward Southeast Oklahoma. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. FRIDAY...Thunderstorm Potential. SATURDAY THROUGH MONDAY...Thunderstorm Potential...Heavy Rain Potential. TUESDAY AND WEDNESDAY...Thunderstorm Potential. EXTENDED DISCUSSION... Thunderstorms chances will continue during the day Friday across much of Eastern Oklahoma and Northwest Arkansas before the cold front pushes south of the Red River Friday evening. Storm chances quickly return late Friday night and Saturday as the frontal boundary tries to lift back northward. By Saturday night into Sunday storm chances become likely across the region ahead of another cold front forecast to push into the region Sunday night and Monday. A limited severe potential could be possible during the weekend...with a greater potential for periods of heavy rainfall over the region. Forecast rainfall amounts in the 2 to 4 inch range could be possible Saturday into Monday which could increase flash flooding concerns across Eastern Oklahoma and Northwest Arkansas. Thunderstorm chances will remain in the forecast into the middle part of next week as the frontal boundary looks to become nearly stationary near the Red River Valley. weather.gov/tulsa contains additional information.
