The episode as NWS JAN wrote it up.
A cold front and strong upper level low pressure system moved through the region on the 5th. As this combined with afternoon heating, an unstable airmass and plenty of wind shear, severe storms developed. These storms brought damaging winds, and hail to the region.

NWS Jackson, MS wrote its last area forecast discussion before the first event at May 5, 1:41 PM CST, 3 hours 12 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 241 PM CDT Thu May 5 2022 .DISCUSSION... Through Friday: A shortwave has initiated convection from near the MS River south of Memphis, WSW through south of Pine Bluff and extending from SE Arkansas into NE Texas. These storms will gradually converge into our Delta areas over the next few hours and progress east and northeastward through the evening. Some of these storms have already exhibited severe characteristics over the past hour or two, and as they move into a region of moderate to strong instability and strong deep layer shear over our northwestern zones this afternoon into this evening, severe weather will continue to be a threat. Given the more linear storm mode and weak directional shear, damaging wind gusts should be the primary threat, but with any discrete cells, large hail is possible, as we've already seen across AR this afternoon. The tornado threat is relatively low but can't be ruled out. While the greatest severe focus will be from northeast LA across into northwest and north MS, additional convection will spread across much of the remainder of the area through the evening. As it does so, it will likely become increasingly boundary-parallel which should generally limit the intensity of the storms with further southward and eastward extent as they become regularly undercut by the cold pool. Still, isolated instances of damaging wind gusts will remain possible into this evening, particularly for any line segments that are able to surge more. We may see a bit of a break behind the initial round of storms, with lagging shower activity and isolated thunder and a more stable airmass overspreading much of the region in the wake of this activity. Overnight, as the main cold front pushes across the area, redevelopment of convection is possible along and ahead of it. Given the limited instability and unfavorable time of day, severe storms appear unlikely at this time. However, we can't rule out just enough instability working back in across south/east MS for an isolated damaging wind gust early Friday morning through around daybreak. Lingering showers will decrease in the east through the morning, with clearing from west to east through the day. Westerly winds will be breezy at times during the day. /DL/ Saturday through Thursday: The prevailing influence on our weather for this weekend through the middle of next week will be an upper-level ridge of high pressure strengthening and building from Northern Mexico toward the Great Lakes. This will be as a low pressure system moves out over the Atlantic over the weekend and then cuts off and stalls off the East Coast, and as a deep trough develops over the Pacific Northwest and helps to amplify southwest flow from the Desert Southwest into the Plains. Surface troughing east of the Rockies and surface high pressure wedged down the East Coast will support continued warm, generally southerly flow over our area into the middle of next week. The effects of high pressure aloft should suppress convection, although heat and humidity will only be on the increase. High temperatures in the 90s are expected to be common by Monday, with forecasted MaxT's above the 90th percentile for early May. Peak heat index values will likely climb to around 100 degrees, which is just shy of thresholds for mentioning in the Hazardous Weather Outlook. But considering this will be the first round of summerlike heat for the season, it is still highly recommended to check on your neighbors and relatives to make sure they are prepared for the warm weather ahead. The pattern becomes less certain at the tail end of the forecast period, as models indicate the low pressure system off the East Coast may begin to retrograde and nudge better moisture and rain chances in from the east. Or it may also erode the eastern edge of the ridge enough to let an MCS run down toward the Gulf Coast from the Midwest at some point. /NF/ && .AVIATION... 18Z TAF discussion: VFR conditions prevail across the region early this afternoon, though S/SW winds are gusty in many areas. However, TS will increase this afternoon and early evening, initially in the GLH/GWO area, spreading south and east through the evening. Some gusts to 50 kt and large hail are possible, and tornadoes can't be ruled out with the highest potential for severe storms in the northwest/GLH area. MVFR ceilings and brief visibility reductions are possible in the heavier storms. VFR conditions may return in many areas overnight before MVFR or IFR low stratus return toward daybreak. Additionally, another round of SHRA or TS is possible early Fri morning as a cold front moves through. Conditions will begin to improve from west to east after sunrise, with VFR conditions returning in most areas by midday. West winds will be gusty at times tomorrow. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
