With the atmosphere particularly favorable for microbursts, widespread thunderstorm activity developed across the southern half of Mississippi during the afternoon of September 9th. Several microbursts and strong outflow boundaries produced wind damage as thunderstorms moved northward.

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 Jackson, MS wrote its last area forecast discussion before the first event at Sep 9, 12:40 PM CST, 1 hour 4 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 140 PM CDT Mon Sep 9 2019 .UPDATE... Updated for Increasing chances of strong afternoon thunderstorms. && .DISCUSSION... Some strong afternoon thunderstorms will be possible mainly in the southern portions of the region as a more moist, unstable airmass advects into the region from the south. The main threat with storms this afternoon will be damaging wind gusts. Prior discussion below: Another warm start to our region today as we continue to remain influenced by a stagnant upper ridge over the Southeast US. Temperatures are still expected to climb into the upper 90s for a good part of the region by this afternoon. However, showers and thunderstorms moving into the region from the Gulf should provide some relief to the scattered locations in the South and West. Late morning radar scans are already depicting showers and storms moving onto land in southern Louisiana. Expecting this trend to continue throughout the rest of the day, this forecast retains the PoPs added by the previous forecast. Prior discussion below: Today and tonight... The region will continue to remain under the influence of a ridge centered over the Southeast states with above normal warmth persisting. At the surface, a weak frontal boundary will continue to slide southwest from northern Alabama into northeastern Mississippi early this morning and through the day. Temperatures will not be noticeably cooler behind the boundary, but dewpoints are progged to drop into the low to mid 60s across northeast Mississippi. Meanwhile, on the other side of the boundary, moisture pooling will result in low 70s dewpoints across southern Mississippi into the ArkLaMiss Delta which will combine with temperatures in the mid to upper 90s resulting in heat index values nearing 105 degrees. A limited risk for heat stress will continue to be maintained in the HWO/graphics for this area with only slight adjustments to the area needed. In addition to the heat, scattered afternoon showers and thunderstorms are expected mainly along and south of the I-20 corridor and across portions of the ArkLaMiss Delta on the moist side of the aforementioned frontal boundary. PWATs nearing 2" will be sufficient to support deep moist convection and the 00z suite of hi-res CAM guidance continues to depict an active afternoon across this area. SBCAPE of 3500-4000 J/kg, vertical totals of 26-28 C and respectable mid-level lapse rates of 6-6.5 C/km will support the potential for a few of these storms to become strong with an isolated severe storm or two not out of the question. The main threat will be for a few instances of locally damaging winds with the strongest storms. Convective activity will gradually diminish after sunset as instability wanes with only a few lingering showers heading into the early evening hours. Overnight temperatures will be mild in the low to mid 70s with a few readings in the upper 60s possible in the Golden Triangle area. /TW/ Tuesday through the weekend... The heat will remain on through the week across the region as upper level ridging remains centered across the Southeastern United States. Temperatures will reach into the mid and sometimes upper 90s through much of the week. Heat indices could approach or even exceed 100 degrees at times but dewpoints could mix just enough to keep conditions tolerable. While there could be a few showers or storms during peak heating, most locations will remain dry through much of the period. The upper ridge will break down toward the end of the week and into the weekend as a front approaches the area from the north. Unfortunately, as the upper level system associated with this front tracks north and east into northeast Canada, the front will not make it into the region. Thus, no relief or hint of fall-like weather is in sight through the end of this forecast period. Some rain may be possible toward the latter portion of the weekend, especially in the southern parts of the forecast area in response to a disturbance in the Gulf moving west. /28/ && .AVIATION... 18Z TAF discussion: VFR conditions will continue to persist at most TAF sites throughout the 24hr TAF period. Scattered thunderstorms will be possible this afternoon into early evening near our southern and western most sites. This prompted the additions of VCTS at KGLH, KJAN, KHKS, KPIB, and KHBG. Visbys will be impacted at any site that is impacted by an afternoon storm. Coverage of storms should begin to decrease by 00z and widespread VFR will prevail through the rest of the period. && .PRELIMINARY POINT TEMPS/POPS...
