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 19, 6:21 PM CST, 9 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 721 PM CDT Sat Jun 19 2021 .UPDATE... Updated for 00Z aviation discussion && .AVIATION... 00Z TAF discussion: In the wake of a tropical system, some remnant shra and low clouds persist in the eastern terminals. Although VFR will be possible for much of the central and western CWA, enhanced llvl moisture for the Pine Belt and the eastern TAF sites will result in a more pessimistic forecast with IFR cigs through early morning. Conditions should improve through the day, with vcsh in the east through the afternoon. && .DISCUSSION... Tonight and Sunday: At mid afternoon local radars showed the center of Tropical Storm Claudette over east central Mississippi. Claudette will weaken as it moves east northeast tonight into Alabama and the rainfall will taper off from the west. Most of the measurable precipitation will end in our CWA a little after midnight. The gusty winds over east Mississippi will diminish this evening as well. has moved into the southern portions of our CWA, the main threat for strong gusty winds, heavy rainfall, and brief tornadoes has shifted east of Mississippi and we have cancelled the Flash Flood Watch and Wind Advisory that was in effect for our CWA. Claudette is expected to track northeast today and slowly weaken. Rain chances and some gusty winds will continue over east Mississippi this afternoon before tapering off this evening. Come Sunday morning wl still have a moist airmass in place and our low level winds will become southerly again. A weak mid level trough also linger over our region. Daytime heating is expected to result in the development of isolated to scattered showers and thunderstorms from the south during the afternoon. With considerably less cloud cover than today, temperatures will top out close to normal in the lower 90s. /22/ Sunday night through Wednesday: Any diurnal precip activity on Sunday looks to taper down by Sunday evening, though southerly flow will continue to advect a humid airmass back into the area. A mid/upper trough will bring a cold front toward the region Monday. Scattered airmass showers and storms will be possible through the day, becoming more numerous into the afternoon with increasing instability from daytime heating and the increasingly moist airmass. The front will dip into our area Monday night into Tuesday, with the highest rain chances Monday night into Tuesday morning. There is some potential for more potent convection developing along the front to our northwest then moving toward the Delta Monday night, but given forecast marginal deep layer shear and the overnight timing resulting in diminishing instability, a severe threat remains uncertain and we have opted not to advertise such pending better support from guidance. We will also need to monitor the potential for flash flooding given the deep layer moisture pooling ahead of the front with PW forecast to surpass 2" (around the 90th percentile of model climatology with moisture transport in a similar range). Though the front looks to hang up over our area then retreat northward, we will see a brief intrusion of drier air Tuesday into very early Wednesday. The surface high in the wake of this front will be quick to shift eastward from the Ohio Valley into the Mid- Atlantic. Once again, moisture will modulate back northward by late Wednesday with more humid conditions beginning to return and isolated to scattered diurnal convection back in the picture mainly over southern portions of the area. Thursday into next Saturday: Typical summertime heat and humidity are anticipated heading into the end of next week, with daily diurnal convection around. A building ridge to our west will result in warmer and drier conditions over the western half of the area with not quite as warm conditions and somewhat greater diurnal convection farther east on Thursday and Friday. By Saturday, another upper trough over the northern Plains will begin to impinge upon the southern CONUS ridge axis, though model solutions vary with respect to how much. We could see rain chances increasing again next weekend if solutions with a deeper trough verify. /DL/ && .PRELIMINARY POINT TEMPS/POPS...
