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 2, 9:25 PM CDT, 5 hours 6 minutes earlier.
Area forecast discussion, Jun 2, 9:25 PM CDT, 5 hours 6 minutes before
Area Forecast Discussion National Weather Service Jackson MS 925 PM CDT Sat Jun 2 2018 .UPDATE... Updated for evening discussion. && .DISCUSSION... Updated the forecast to reflect the current trends. Storms to the west continue to pound that area but weren't quite making much southward progress. Storms just ahead of the boundary were a little further away, so slowed the rain moving into the area. It looks like another hot and muggy night with mid to upper 70s likely. Could see one or two record low max records broken at Hattiesburg, Jackson or Meridian. Other than the timing of the rain, no really changes to the forecast./07/ && .AVIATION... 00Z TAF discussion: VFR flight categories will continue to prevail at all TAF sites into this evening. A complex of showers and storms are progged to rapidly drop south southeast into and through the area late this evening and during the overnight hours. Convection during this time will cause both ceilings and visibilities to drop to MVFR/IFR categories for at least a 1-4 hour period of time. Gusty northwest winds are expected with this complex, along with frequent lightning, and heavy downpours. Both ceilings and visibilities will quickly improve in the wake of this convection. Winds will subside to light from the west around 3-5 knots ahead of the complex. /17/19/ && .PRELIMINARY POINT TEMPS/POPS...
