The episode as NWS JAN wrote it up.
Slow moving afternoon thunderstorms produced heavy rain and flash flooding in parts of southeast Arkansas.
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 Aug 9, 12:26 PM CST, 1 hour 19 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 126 PM CDT Tue Aug 9 2022 .UPDATE... Updated for 18Z aviation discussion. && .AVIATION... 18Z TAF discussion: An area of showers and thunderstorms has developed across parts of the forecast area, with TSRA likely to impacts several of the TAF sites before around 00Z Wednesday. A chance for SHRA or TSRA will continue after that time frame, but confidence in impacts to any one TAF site are low at this time. Any storms could cause brief periods of reduced visibility, variable ceilings, and gusty winds. Another round of showers or storms will develop and begin to affect the area TAF sites after 12Z Wednesday. There is a chance for some patches of low stratus or fog late tonight, but with rain chances around, confidence was low for inclusion in the TAFs yet. /NF/ && .DISCUSSION... Abundant moisture is in place across our forecast area today. Regional soundings analyzed PWAT values around 2.0 inches, with the potential for 2,000-4,000 J/kg of SBCAPE through the afternoon before convection overturns the atmosphere. Forecast soundings show a tall/skinny CAPE profile which, when combined with high PWATs and weak steering flow, would support the potential for localized heavy downpours. Storms today could produce some isolated flash flooding, especially given the recent rainfall around the region. Will introduce a "Limited" threat area for localized flash flooding into our HWO text and graphics through tonight to account for isolated heavy downpours. /NF/ Prior discussion below: Today through tonight...A tropical airmass prevails across the ArkLaMiss with PWATS ranging around 2.0 inches. This combined with afternoon heating will kick of afternoon thunderstorms once again. Expect scattered storms to develop by early afternoon and continue through much of the day. Lapse rates will be marginal today, ranging from around 5.2-5.7 C/KM along with very little flow. With light flow the main risk today will be heavy rainfall, but a strong storm or two cannot be ruled out. A frontal boundary will drift closer to the northern portions of the area tonight and this may help kick off a few storms across the Delta overnight. High temperatures will be cooler today, topping out around 90 degrees with overnight lows in the low 70s. /15/ Wednesday through Monday: Cooler than normal temperatures with above normal rain chances are expected Wednesday through Friday. A backdoor cold front will move through the CWA for the start of the weekend lowering rain chances in its wake. Temperatures will warm back to normal Sunday and Monday. Come Wednesday wl still have a tropical airmass in place with PWATs above two and a quarter inches. Our CWA will be in the weakness between a stout mid level high centered near the Four Corners region and a second a stout mid level high centered just off the southeast coast. The Four Corners high will expand a little eastward through Friday while the mid level high off the southeast coast weakens and allows upper level troughing to deepen down the east coast. This will help send a backdoor cold front into our northeast most zones Friday afternoon that looks to stall just south of our southern most zones by Saturday afternoon. In the wake of the cold front PWATs wl be knocked down below and inch and a half with surface dewpoints in the upper 50s to lower 60s over the northeast half of our CWA. Daytime heating of our moist airmass combined with lower heights Wednesday through Friday will lead to a decent coverage of storms each day. Rain chances will be more confined to our southern zones Saturday and Sunday. Temperatures will warm back to normal Sunday and Monday but Monday will also see a moisture return. Heat index values are not expected to be an issue until perhaps Monday afternoon over portions of our delta where peak heat index values may approach 105F again provided the deep moisture return occurs as anticipated. /22/ && .PRELIMINARY POINT TEMPS/POPS...
