The episode as NWS JAN wrote it up.
A mid-level shortwave trough moving across the Southern Plains triggered a line of thunderstorms to develop across Arkansas and Louisiana on June 10th. As these storms intensified and spread east into Mississippi during the afternoon hours, additional scattered strong to severe storms developed in the unstable air mass over Mississippi. These thunderstorms produced hail and wind damage including some swaths of significant wind damage associated with microbursts.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 10, 11:38 AM CST, 17 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 1238 PM CDT Sat Jun 10 2023 ...New AVIATION... .DISCUSSION... Issued at 401 AM CDT Sat Jun 10 2023 Today and Tonight: early morning water vapor imagery/RAP analysis had the large closed low that has been over the New England states the last couple of days, north of Maine and into Canada. The upper level trough axis associated with this low will continue shifting east today and our northwest flow aloft early this morning will become more zonal by afternoon. A shortwave trough within this nearly zonal flow aloft will move over our CWA during peak heating and enhance convection; some of which may become strong to severe. The 00Z Saturday JAN sounding had a PWAT of 1.68in and PWATs are expected to increase above an inch and three quarters this afternoon. Early morning surface analysis showed dew points in the upper 60s to lower 70s. Surface analysis had a weak ridge across the Gulf coast from the east that is expected to result in a light southerly wind today that will help maintain low level moisture through the afternoon. Together these features are expected to lead to a greater coverage of mainly afternoon and evening convection. CAMs suggest that convection across our CWA will increase by noon and to our west as the shortwave trough approaches. By mid afternoon the convection to our west may become more organized and spread into our CWA. This activity will bring a risk for damaging winds and perhaps hail to quarter size. This activity is expected to continue spreading east southeast across our CWA during the evening and should dissipate or shift southeast of our southeast most zones before midnight. Temperatures are expected to make it into the lower 90s at most locations before getting knocked down by convection. Our lows tonight will run warmer than normal. /22/ Sunday through Monday... The system should begin to track east out of Mississippi by Sunday morning as a another closed low tracks south from Central Canada into the Ohio River Valley. This should allow for a cold front to push into our CWA by Sunday night. Some strong storms could occur ahead of this front mainly along and north of the I-20 corridor. With SBCAPE near 2500 J/kg, steep mid-level (700mb-500mb) lapse rates around 6.5 C/km, and PWAT values near 1.62 inches, the environment looks favorable for isolated severe convection. Because of this, we will continue advertise a "Marginal" Risk for isolated severe storms. Damaging wind gusts up to 60 mph along with hail up to quarter size will the main hazards with this system. At the moment, current model ensembles show a weak QPF signal stretching across our forecast area. Overall, rainfall amounts should remain on the lighter side across most of central Mississippi. Areas north of I-20 could see rainfall amounts up to a half an inch where localized downpours will be possible. As the cold front shifts further south and stalls across the lower Mississippi Valley late Monday afternoon, there is a possibility that thunderstorms could redevelop south of I-20. After collaborating with the Storm Prediction Center (SPC), we will advertise a "Marginal" risk for isolated severe storms with damaging wind gusts and quarter size hail being the primary hazards. The closed low should begin to slowly track northeastward along with the cold front and clearing out of our forecast area by late Monday evening. Tuesday through the weekend... Out towards the west, a low pressure system centered across California is slowly pushing eastward across the southwest CONUS. In response to this, a ridge axis is tracking east across the Southern Plains towards the southeast US. This should allow for warm gulf air to settle across our CWA leading to increasing temperatures and diurnal convection. Wednesday through Friday looks to be the hottest days with afternoon highs forecasted to peak in the mid to upper 90s across the southeast region. A couple of locations could see heat indexes reaching 105. In response to this, we will continue to advertise a "Limited" risk for heat stress mainly for the southwest portion of our CWA. Make sure to stay hydrated and take frequent breaks if working outdoors. /CRJ/ && .AVIATION...

A few trees were blown down near MS Highway 492 and its intersection with Conehatta-Prospect Road and Kitchner Road.
A severe thunderstorm interacted with cold outflows from preceding thunderstorms and produced widespread wind damage in a swath beginning near the Hinds County line and Interstate 55 northeast toward the Deerfield Golf Club at Old Canton Road and Yandell Road. A tree was blown down onto and blocked County Line Road, and some trees were blown down in the parking lot of the Renaissance at Colony Park near the beginning of the swath. Intermittent damage to trees was noted apart from the swath, but a more significant corridor of damage across southern and central Madison County was consistent with downburst winds estimated winds at 75 to 85 mph. The main part of the downburst event appears to have originated in the vicinity of Bruce Campbell Field in Madison where minor damage was observed to awnings and gutters at a church on Ridgecrest Drive. Tree falls and overall impacts were maximized just north of the airfield in the vicinity of Strawberry Patch Park and adjacent areas near Hoy and St. Augustine Roads. Numerous trees were downed generally from south to north, and some minor damage to sheet metal awnings, carports, and shingles occurred. In this vicinity, several homes, outbuildings, and power poles and lines sustained damage from falling trees. It is this area where winds were estimated to be the strongest - around 75 mph. To the south and east, tree falls were generally west to east with relatively minor structural impact and decreasing tree fall density. Only downed large branches were noted along the Natchez Trace two miles southwest of the Highway 43 intersection. To the north, tree falls remained generally south to north with similar reductions in frequency and severity of vegetative damage with northward extent. Most notably, areas north of the Quail Hollow and Clarkdale Road vicinity saw increasingly isolated instances of damage. Areas where fencing was oriented perpendicular to the gusty southerly winds were damaged as far north as eastern portions of Gluckstadt. The length of this damage swath was around ten miles long and four miles wide.
A road sign down along Interstate 55 South and Lakeland Drive was blown down, and a large tree was blown down onto a home near Canton Mart Road.
Several trees and power lines were blown down near Caney Church Road and Prospres Ridge Road.
