The episode as NWS SHV wrote it up.
Scattered to numerous showers and isolated thunderstorms developed throughout the day on June 5th, ahead of a stationary cut off upper low pressure system over Central Texas. Daytime heating contributed to moderate instability within a very moist air mass in place. These showers and thunderstorms were very efficient rainfall producers as they moved slowly and often trained over the same areas over a given period of time. Showers and thunderstorms containing heavy rainfall developed over much of Panola County during the late afternoon through the evening, with widespread rainfall amounts of 4-8 inches falling over this area. These amounts fell over already saturated grounds from heavy rainfall which fell a day prior, with two day totals of 6-12 inches observed. This resulted in widespread flash flooding across Southern and Eastern Panola County, where multiple roads were covered in high rushing water, including Highway 59 just south of Carthage. These showers and isolated thunderstorms finally diminished during the late evening hours.
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 Shreveport, LA wrote its last area forecast discussion before the first event at Jun 5, 6:30 PM CST, 1 hour 1 minute earlier.
Area Forecast Discussion National Weather Service Shreveport LA 730 PM CDT Sat Jun 5 2021 .AVIATION... For the 06/00Z TAF period, a mixed bag of cigs starting out this period with mostly VFR and MVFR conditions, and expect further deterioration through the overnight hours. Vsbys have also been reduced at times due to robust convection across most terminals this afternoon with ongoing showers and thunderstorms through the evening hours. A general decrease in convection should come after midnight, but expect a near repeat on Sunday as heating enhances development of more showers and storms. MVFR/IFR cigs will likely prevail through much of Sunday with some possible improvement by late in the TAF period. Otherwise, look for winds to maintain a general SE component with speeds between 5-10 kts on average. /19/ && .PREV DISCUSSION... /issued 216 PM CDT Sat Jun 5 2021/ SHORT TERM.../Tonight through Tomorrow Night/ At the synoptic level, hardly anything has changed regarding the overall pattern in the short-term period. Now under greater influence from the upper-level wind regime, the low pressure is now moving north/northeast. This process will continue, eventually speeding up as ridging aloft near NE Mexico provides an extra boost. As such, shower and thunderstorm chances will remain pretty steady over the next 36 hours. Most of this activity is diurnally driven, so rain chances will slightly diminish during the overnight, but pick right back up into tomorrow. Observed PWAT values are now starting to push two inches under the stout Gulf flow, which will help any of these storms to be rather efficient rain producers. As such, poor drainage areas and the usual problem spots will be susceptible to flash flooding. Overnight low temperature will continue to be well below average under cloud cover and a very wet airmass. Lows both tonight and tomorrow night will range from the upper 60s to low 70s. Due to limited sunlight tomorrow, afternoon highs will only get up into the upper 70s north, and low 80s south. /44/ LONG TERM.../Monday through Saturday/ As we begin the upcoming work week, unfortunately, the weather pattern will have changed very little. We are still dealing with a very wet pattern across the entire Four State Region, due in part to a stubborn upper level trough parked across N TX. The good news is that by late Tuesday, the remnants of this trough should begin to slowly fill and lift out to the north and northeast. This should limit storm coverage somewhat as we move into the middle part of the work week and especially by the end of the work week with the aid of upper level ridging that will try to nudge its way into our region from the south and west. By next weekend, there are some indications that ridging will setup to our north across the Southern Plains with somewhat of a shear axis south of this feature or across our region. If this were the case, then we would have to contend with at least scattered diurnally driven convection even into the upcoming weekend as well with at least the GFS trying to show something tropical rapidly moving north and northwest towards the upper Texas Coast. Lots of time to watch this pattern play out or not but the 00z run of the ECMWF, while showing the increasing upper ridging from the southwest by late week, does not show anything tropical in the Gulf for next weekend. What the progs do agree on is an uptick in temperatures for the end of the work week into next weekend as precipitation coverage decreases which is to be expected for the second week of June. 13 && .PRELIMINARY POINT TEMPS/POPS...
