The episode as NWS JAN wrote it up.
Afternoon heating combined with abundant moisture produced severe thunderstorms.
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 Jun 3, 5:40 PM CST, 15 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 640 PM CDT Wed Jun 3 2020 .UPDATE... Updated for 00Z aviation discussion && .AVIATION... 00Z TAF discussion: Ongoing SHRA/TSRA this evening will bring lowered vis and ceiling restrictions below VFR. Once storms pass and outside of storms, VFR conditions should occur. Given increasing low level moisture in place over the region, stratus should be a concern overnight through daybreak. This will lead to MVFR to IFR ceilings for most TAF sites. Ceilings should improve mid to late morning but additional showers and storms will be possible tomorrow afternoon and evening. These will reduce ceilings and vis once again to MVFR or lower. /28/ && .DISCUSSION... Tonight and tomorrow... Unsettled weather will continue showers and thunderstorms through the evening and again tomorrow as the weather pattern remains warm and moisture laden over the region. Diurnally enhanced showers and thunderstorms will slowly weaken and become less widespread later on this evening, though continued shower development will be possible sporadically through the evening. Precip chances return again tomorrow...increasing in coverage through the afternoon hours. A general risk of diurnal convection will get an assist from the remnants of an MCS that moves into the mid Miss River Valley tomorrow afternoon. A marginal risk for severe storms exists mainly for northern MS and southeastern AR...with the main threat being gusty winds and large hail. Overnight tonight, plenty of cloud cover and muggy air will keep the early morning lows in the upper 60s/lower 70s. Tomorrow, high temperatures will climb into the upper 80s for much of MS...and lower 90s west of the Miss River and in portions of the Delta north of I-20. Tomorrow night through Wednesday... The forecast starts off tomorrow night with a belt of northern stream westerlies across the Northern Plains with a southern stream closed low off the California coast and a mid-level ridge over far northern Mexico. Weak troughing will be in place across the southern states with Tropical Storm Cristobal meandering over the Yucatan Peninsula well to our south. A few showers and storms may be ongoing at the start of tomorrow night, but will quickly wane through the evening hours with loss of daytime heating. Another round of diurnally driven showers and storms is expected on Friday with warm afternoon highs in the upper 80s and low 90s. Attention quickly turns to Tropical Storm Cristobal as we head into the weekend. Cristobal will finally start making northward progress on Friday and will be nearing the northern Gulf coast on Sunday morning. The aforementioned closed low off the California coast is progged to evolve into an open wave as it moves onshore and phases with a larger northern stream trough over the Pacific Northwest. At the same time, the mid-level ridge will shift northeast and become centered over the Middle Mississippi River Valley. Uncertainty still exists with regards to eventual track and any impacts to the ArkLaMiss region. Current global guidance indicates a brief slow down in forward motion owing to the ridge before the tropical storm slides northwest and into a weakness between the departing ridge and shortwave trough ejecting out of the Rockies. Confidence is also low with respect to intensity as the system will be fighting vertical wind shear over the northern Gulf of Mexico. Regardless, tropical moisture will begin to overspread southern portions of the area on Saturday with the greatest rain chances and coverage Sunday through Tuesday. It is still too early to try and iron out any impacts due to the inherent uncertainty in both track and intensity, but at least a localized flooding threat appears possible. /TW/ && .PRELIMINARY POINT TEMPS/POPS...
