Strong to severe thunderstorms developed along a southward moving outflow boundary from previous convection that moved south earlier during the predawn hours across Northeast Texas. These storms developed along a remnant cold pool outflow boundary and the atmosphere was unstable enough across this region that periodic wind damage occurred with the storms.

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 Shreveport, LA wrote its last area forecast discussion before the first event at Jun 23, 10:55 PM CST, 2 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Shreveport LA 1155 PM CDT Fri Jun 23 2017 .AVIATION... For the ArkLaTex, a line of convection with only occasional thunder now, is draped along a cold front over NE TX and along an intersecting outflow from KGGG to KAEX. The cold front will filter N/NE low level winds area wide just as the morning stratus is lifting after daybreak and additional convection may crop up toward daybreak and linger all morning. We will slowly ease back to VFR into the afternoon with drier air working in the area. /24/ && .PREV DISCUSSION... /issued 1114 PM CDT Fri Jun 23 2017/ DISCUSSION... Quick zone update just sent to make a few minor adjustments to pops tonight. The gust front from the earlier AR MCS continues to makes steady progress SW across NE TX/N LA attm, with additional sct strong to occasionally svr convection developing along this gust front as it intersects a weak sfc front extending across N TX just N of the DFW Metroplex E to just S of PRX to near TXK, and extreme Nrn LA, where it has been convectively reinforced from the earlier MCS. The air mass remains quite unstable ahead of the ongoing bndrys where SBCapes of 3000-4000+ J/Kg remains present across much of E TX/Wrn LA. However, weak mid level winds and and the lack of deep lyr forcing should keep this convection loosely organized, with the initial shortwave driving the earlier AR MCS having already dropped SE across the Delta region/Lower MS Valley where the air mass is more stable. However, the short term progs do hint at additional development occurring overnight across the middle Red River Valley as a second shortwave noted on the evening water vapor imagery over W TX/Cntrl OK helps to initiate additional sct/numerous convection as it spreads SE across the region. The only fly in the ointment is the fact that how much instability will remain and whether the existing gust front/cold front slow overnight, but could help to focus additional convection as forcing increases late with the approaching shortwave. The short term progs remain all over the place with where/how much convection will develop as only the 18Z NAM actually initialized best on the AR MCS, with the HRRR playing catchup all night and also lacking convective development over much of E TX. However, believe the svr threat will remain isolated given the weak overall forcing and especially as the gust front continues to propagate SW and cool/stabilize the air mass. In the update, did lower pops to chance across SE OK/SW AR, but maintained likely pops over much of E TX/N LA with the ongoing convection. Did not make any changes to forecast min temps, but will be dependent on the gust front/sfc front passage. Grids will be available shortly. 15 && .PRELIMINARY POINT TEMPS/POPS...

With the remnants of Tropical Storm Cindy having moved well north and east of our region today, much of the rainfall associated with Cindy will move north and east with her. However scattered showers and a few thunderstorms lingered across portions of southwest Arkansas and north central Louisiana late this morning, with a few storms approaching strong levels. A gradual eastward shift of the precipitation exiting the region will take place by this afternoon. The lack of scattered showers and thunderstorms will be temporary as a cold front will begin moving into the Middle Red River Valley of Northeast Texas, Southeast Oklahoma and Southwest Arkansas this evening. Along with this frontal boundary will be scattered to numerous showers and thunderstorms and this activity will build southward towards the Interstate 20 Corridor of Northeast Texas and Northern Louisiana late tonight. Some of these storms could become strong to severe overnight, with damaging wind gusts and large hail will be the primary threats. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Scattered to numerous showers and thunderstorms in association with a cold front will effect most of the Four State Region during the day Saturday before the activity tries to push southward and taper off Saturday Night into Sunday along with the cold front. Low chances for showers and thunderstorms will remain in the forecast through early Monday mainly along and south of the I-20 Corridor as well. Otherwise, we should see a drying trend through the early part of next week with low rain chances returning once again by the end of the upcoming work week. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators...and storm spotters may be needed tonight.
