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 2, 1:44 PM CST, 1 hour 17 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 244 PM CDT Wed Jun 2 2021 .DISCUSSION... Tonight and Tomorrow... An upper level trough centered across the plains with an associated frontal boundary has brought the ArkLaMiss a very moist set-up. This is a summertime like pattern that we are in and this unstable pattern will stick around through tomorrow as well. Showers and storms(some with embedded thunder) will be the case through this evening. There is a chance for a strong storm or 2 to occur across the south/east before the day is over with but widespread strong to severe storms are not anticipated. With the atmosphere being as moist as it is, there is a chance that some storms and or as rainfall moves through the area, pockets of heavy rainfall will be possible. Unlike yesterday where some areas out west received almost 2 inches, places across the south and east have not seen as much rain fall so even if heavier rainfall occurs, flash flooding is not a major concern. Rain will continue into the overnight hours but should be light. By tomorrow, the upper-level trough will swing across the Mid and Deep South however, rain and storm chances will be confined to the south and some parts of the east as the previous mentioned boundary pushes through the region. Rain will start to tapper off from the south to the east by tomorrow afternoon through early evening. Highs tomorrow will range from the mid to upper 80s./JNE/ Thursday night through Next Wednesday... For the Thu Night to Wed period our region will continue to see the general flow regime featuring "cut off" energy and slow evolution before E conus ridging builds. What does this mean in an overall sense? For temps, look for near normal to slightly below normal conditions. For precip, there will be a wet several days mixed in where some flooding may become an issue. Right now that appears to be in the Sun-Tue timeframe. Taking a closer look, the "cut off" upper low pattern continues to build support from the overall guidance. As a result, the trend we discussed yesterday for lower PoPs continued and some values are down a bit more from the prev forecast. This is mainly in the Thu Night to Sat periods. This will have some impact on temps and the warmer trend is still supported. The latest 12z guidance did warm a bit from the prev run, but I trended closer to climo for most areas with MaxT for both Fri & Sat. Friday morning the N half will be on the cool side with low/mid 60s as a weak boundary will sag S more into the area. We may see some fog develop due to sufficient clearing/cooling and proximity to the boundary. Right now, not confident enough to add into the official forecast. By Sun, we should see the upper low begin to open up a bit and lift out as a larger system enters the Pac NW. The E conus response to this larger system will promote ridging and our lifting upper low will be slow to do so and likely try and lift with more of a N/NNE trajectory. This will likely spell a longer duration precip event for most or part of our forecast area. Based on various operational guidance and ensemble data, the Sun-Tue period seems to be primary timeframe at this time. This is more of a heads up mention of the potential as details this far out and with such a system are tough to get right 4- 6 days out. Temps during this time will likely remain below normal with a day or so a good bit below normal. With more mid/upper level ridging taking shape for mid to late week, look for precip chances to lower and temps to trend warmer to more seasonal readings. /CME/ && .AVIATION... 18Z TAF discussion: VCSH, VCTS, SHRA, and -RA will affect all sites except for GWO at some point through out the TAF period. Ceilings will toggle back and forth between VFR and MVFR. Rain coverage will continue throughout the day but is expected to diminish tonight. However low clouds will still be on tap and sites MEI, HBG, and PIB will drop down to IFR briefly before daybreak tomorrow morning but conditions will improve shortly after. Winds will be out of the SSW and breezy during the day today, up to 10kts with possible gusts up to 20kts for sites across the central and eastern parts but winds should subside come early evening./JNE/ && .PRELIMINARY POINT TEMPS/POPS...
