The radar
The Jackson/Brandon,MS radar (KDGX), 10 km from the middle of the area, began a volume at 23:20 UTC, the scan nearest the moment this went out.

Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

GRGWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 22, 4:35 PM CDT, 1 hour 42 minutes earlier.
Area forecast discussion, Jun 22, 4:35 PM CDT, 1 hour 42 minutes before
Area Forecast Discussion National Weather Service Jackson MS 435 PM CDT Fri Jun 22 2018 ...SEVERE THUNDERSTORMS POSSIBLE THROUGH EARLY THIS EVENING OVER PORTIONS OF THE REGION... .DISCUSSION... Through the day Saturday: Solid convective cluster has finally taken shape over the northwest portion of the forecast area in the last few hours, with this cluster advancing steadily southeast toward the heart of the region. Throughout the day convection has shown a tendency to "back-build" into an impressive nose of warmth and moisture advection aloft anchored over the Arklamiss Delta. Lately this advection feature has opened up a bit and is less focused, aiding the ability of convection to start propagating southeast. Meanwhile, the cold pool from persistent convection over northwestern zones throughout the day has generally advanced well southwest of most vigorous convection, thus ensuring the bulk of storms were "elevated" above the surface, reducing their respective potential to produce severe weather. Anyway, latest trends are increasing severe potential once again into early this evening, especially over the western two-thirds of current SVR watch # 197. The main risk through early this evening will be damaging wind gusts, although some hail (and even a stray and brief tornado) cannot be ruled out owing to seasonably impressive low level shear. The SVR watch currently is set to expire at 7 pm, but given trends it is certainly possible it may have to be extended in time a few hours, at least south of I-20. Flooding was a large concern north of I-20 over the Arklamiss Delta, but the trend toward forward-propagation (i.e., movement) is somewhat reducing the threat of at least major flooding. Thoughts are that the convective cluster should exit the region to the south/southeast by mid to late evening with a good deal of the shower and storm ending in its wake. However, latest expectations are that composite moisture convergence and advection will increase well upstream (to the west/northwest) of our region this evening in advance of another vigorous storm cluster developing toward the Red River Valley. There is some potential either this cluster, or another batch of thunderstorms induced by this cluster, will progress east/south down the re-orienting baroclinic zone and pass in the vicinity of our northern zones late tonight through tomorrow morning. A MARGINAL risk of severe thunderstorms was included in the graphics and HWO to handle this threat, but due to a high degree of uncertainty in this chaotic convective regime, there is some chance the threat will be either removed later or even upgraded. Tomorrow, by midday any storms passing through northern zones should be largely to our east or lifting to the north, leaving are region partly cloudy, seasonably breezy, and very humid. High temperatures getting into the lower 90s (and approaching the mid 90s in a spot or two) should yield heat index value near or exceeding the century mark over the majority of the area by the afternoon. Currently thinking heat advisory thresholds will not be met tomorrow so will continue to just highlight the heat stress in the graphics and HWO. /BB/ Saturday night through the work week... The story of the weekend into the work week will be that of increasing heat and humidity. The upper trough will be to our east, which will leave zonal flow and/or broad ridging across the area. With moisture left in place, this will allow for heat stress issues to begin to be a concern for much of the area on Sunday. In addition, capping should allow for a decrease in shower/storm activity. This heat concern will continue through much of the week for entire area as high pressure will expand west from the Atlantic. As heights rise, temperatures will also be increasingly warmer with some locations seeing highs in the mid 90s. This, combined with dewpoints in the mid 70s, will bring heat indices near 105 degrees. In some instances, this threshold will be exceeded. Heat advisories may be likely this week. One caveat to this may be the increased potential for diurnal showers and storms through the week. For residents planning outdoor activities, it will be wise to continue to monitor the potential for higher heat indices through the week. /28/ && .AVIATION... 18Z TAF discussion: Most ceilings (at least away from the midst of thunderstorm activity) have improved to VFR at this point although there remain lots of scattered to broken decks near or above 3 kft around the region. Main thunderstorm activity is training southeast across SE AR, NE LA, and SW MS, and will continue to do so through the afternoon hours. Other pockets of more isolated storms will also tend to pop up through the day. Any locations impacted by storms could experience very gusty winds and temporary IFR conditions through early this evening. Most activity will diminish by late evening with low level ceiling issues, mainly in the VFR range, expected to build in again late tonight in most areas. There is potential for additional thunderstorm activity to approach from the northwest late tonight and may impact GLH/GWO/CBM/GTR corridor late tonight through Saturday morning. Otherwise, expect surface winds away from thunderstorms to be mainly from the southwest at 10 to 15 mph and occasionally gusty. /BB/ && .PRELIMINARY POINT TEMPS/POPS...
