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 May 13, 3:28 PM CST, 1 hour 13 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 428 PM CDT Fri May 13 2022 .DISCUSSION... Through Saturday: With the weather pattern featuring a large upper low over the southeast CONUS and an upper ridge to our west continuing to focus a persistent moisture convergence axis over the forecast area, we're seeing another round of strong to severe storms develop today. As described in previous discussions, these storms are efficient wind producers as they move into an anomalously hot boundary layer given steep lapse with low level lapse rates, and with drier air aloft resulting in DCAPE values ~1000 j/kg. Having said that, it appears the storms are beginning to run out of instability given the earlier start today, so these may not persist long into the evening. With the upper level pattern continuing to support substantial NNW flow, we'll maintain some rain chances overnight, and will also be monitoring for the potential for upstream MCV activity to initiate a convective system as we go into early Saturday. It is possible any early morning activity could supply boundary convergence for development later in the day with heating - confidence is low in how this scenario will play out, but the environment may be favorable again for a few downbursts with damaging wind gusts and perhaps some hail. /EC/ Saturday night through Friday: The forecast for the long term period will be a tricky one. The atmospheric pattern will be of a more summertime like meaning diurnal showers and thunderstorms will be possible mainly at the beginning of the period. Large troughing and an area of low pressure just off the MS/AL coast will help initiate perturbed flow through the ArkLaMiss Saturday. Scattered showers and thunderstorms will be possible mainly all day Saturday and through the evening hours. Troughing will begin to lift north and by Sunday morning, northwesterly flow will build in and we will remain dry for much of the day Sunday but can't rule out a light shower during the afternoon across the Pine Belt. Mid and upper level ridging will begin to approach the region from the west late Sunday night but not before a weak frontal boundary drops in from the north as the previous mentioned trough continues to pull north/northeast. The front is expected to stall across our north late Sunday night and therefore bringing the chance for rain and thunderstorms mainly north of I-20. While widespread organized storms aren't a concern, if we are able to destabilize enough, an isolated storm or two may become strong to severe with the main threats being damaging wind gusts and small hail. Will continue to advertise the Marginal risk across our north. Showers and a few rolls of thunder may linger into the day Monday but severe is not anticipated. Under this northwesterly flow regime, ridging will begin to build back into the region Monday evening. Dry and hot weather can be expected Tuesday through Friday. While the north may see some relief from the heat due to the rain Monday, temperatures will waste no time climbing back into the mid 90s the following days making next week another hot one! A particular long range model tries to hint at another weak disturbance pushing across the area Tuesday however as I stated at the beginnging, this forecast is a tricky one. While ridging will take place for much of the extended forecast there could be chances during evening hours where the ridge flattens just enough for a disturbance to sneak in and produce a few showers. Other models indicte other wise. Due to low confidence and spread within the models will continue with the dry trend Tuesday-Friday./JNE/ && .AVIATION... 18Z TAF discussion: A persistent weather pattern will bring more diurnally enhanced convective precipitation, and early morning LIFR category stratus/fog particularly over eastern/southern portions of the forecast area. Otherwise, outside of TSRA, VFR conditions and light wind will prevail. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
