What forecasters said that day
The local office's own words before this flash flood watch went out, 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 this flash flood watch went out at Jun 9, 1:08 AM CDT, 2 hours 55 minutes earlier.
Area forecast discussion, Jun 9, 1:08 AM CDT, 2 hours 55 minutes before
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 108 AM CDT Wed Jun 9 2021 .UPDATE... Updated for 06Z aviation discussion && .AVIATION... 06Z TAF discussion: A band of TSRA was noted on radar just north of HWY 82 and should remain north of GLH-GWO-GTR tonight. IFR cigs have developed over east MS while VFR conditions were still being observed elsewhere. MVFR to IFR cigs are expected to develop areawide by 09Z and prevail until after 16Z when VFR conditions are expected to prevail areawide again. Scattered to numerous TSRA are expected to develop during the afternoon along and north of I-20 with more isold coverage across the south. /22/ && .DISCUSSION... A few straggling storms remain across the Highway 82 corridor and north. One has become severe but others might produce locally heavy rainfall. Much of the region should be quiet overnight but hi res guidance indicates some convection lingering just to the north of the forecast area. POPs have been adjusted accordingly and going forecast is otherwise in decent shape. /28/ Prior discussion below: Tonight & Wednesday: Tonight: Some flash flooding potential could linger into the early evening hours. Closed low aloft will become less organized & progged to slowly move E-NE out of the Ozarks into the Mid-Upper MS Valley. This will help drive a southern stream shortwave trough axis west of the MS River around midnight & right along the MS River by daybreak. With subtle ascent, high PW/low-level Theta E in the cloud bearing layer, heavy downpours can't be ruled out. Due to this, kept the current HWO graphic/threats as is, but most should end by early evening. With high PWs & HREF guidance indicative of MCV potential but limited coverage, convective potential will be tricky overnight. Flash Flood Watch is only going to go through 9PM, due to lower confidence in convective redevelopment. Severe potential looks less likely, but can't rule out some stronger storms with any redevelopment. Lows will remain above normal due to clouds & high low-level moisture. Wednesday: Trough axis will propagate across the region on Wednesday, leading to increased low-level convergence & ascent. Any lingering rain & storms will become more robust as heating increases. Scattered-numerous rain & storms are expected, mainly across the Hwy 82 & Hwy 45 corridors. Expect any convection to become robust into the afternoon. Lapse rates & minor-moderate destabilization will lead to some efficient cold pool potential, but vertical totals will be less than today. Best wind potential will again will be segments bowing more to the E. Some strong to isolated severe storms, with gusty winds, can't be ruled out but will be more diurnal & mesoscale driven. Any MCV, which continues to be depicted in HREF CAM suite guidance, could help coverage to pick up. In addition, high moisture laden air could help convective coverage to pick up by mid-morning. With being highly mesoscale driven & less microburst potential, will hold off mention for now. Heavy downpours are again possible, but coverage will be a little more scattered & less focused over the same area with wet antecedent conditions. Will hold off any mention in the HWO for now. Highs will again near normals, but slightly cooler in the N & E where more rain/storms will reside. Some heat stress from warmth/humidity is possible, with heat indices into the upper 90s. /DC/ Wednesday night through Monday night: the mean trough position will shift a bit more to the northeast of the ArkLaMiss as we finish up the week and go into the weekend, while ridging increases over the Southern Plains to our west. Cyclonic flow aloft should continue to support a considerable amount of thunderstorm activity, and it may not necessarily peak during the afternoon/evening. There could be a sneaky heavy rain threat with this sort of pattern as a persistent moisture convergence may attempt to set up with northwest flow aloft along the eastern edge of the increasing ridge. Looking ahead to early next week, we should see hotter weather and decreasing rain chances overall with the ridge expanding more into the ArkLaMiss region. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
