The episode as NWS SGF wrote it up.
Little rain fell in September, further impacting the drought that began in August. The 30/60/90 Day precipitation amounts continued to decline with Severe (D2) drought expanding across portions of the Ozarks. Low stream flows were noted on some area rivers and KBDI indices rose indicating enhanced fire weather concerns. Some indication in the agricultural community were beginning to occur with some farmers starting feeding hay about a month early.
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 Springfield, MO wrote its last area forecast discussion before the first event at Aug 31, 10:46 PM CST, 1 hour 15 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 1146 PM CDT Mon Aug 31 2020 .SHORT TERM...(This evening through Tuesday) Issued at 223 PM CDT Mon Aug 31 2020 Cold pool from convection earlier today has made through to all but our southwest counties. Another disturbance is expected to move ene from eastern KS/OK late tonight into Tuesday. Expect elevated convection to increase in coverage and intensity, mainly after midnight along a slow moving weak sw-ne frontal boundary from northeast OK/southeast KS into central MO. MUCAPE values of 2500 j/kg and PWATS increasing to around two inches will support some strong-severe storm potential (wind/hail) with areas of heavy rain. Hard to be precise where the heavy rain will occur, but in general our western counties will have the best overall chances and the rain is needed there with D0-D1 drought. Do not plan to issue a flash flood watch at this time. Expect the convection to shift fairly quickly to the east late tonight into Tuesday morning. The left over convective boundaries and diffuse frontal boundary may serve as a focus for scattered late afternoon/evening storms on Tuesday, but the smaller mesoscale picture by that time will be muddy (i.e. low confidence). .LONG TERM...(Tuesday Night through Monday+) Issued at 223 PM CDT Mon Aug 31 2020 Better chances for convection will shift southeast with time still affecting our eastern counties Tuesday night into Wednesday. Overall, rainfall amounts are progged to be highest over southern MO, but overall excessive rain chances look slight/limited. Does bear watching while we still have quite a bit of moisture in place today through early Wednesday. By late in the week guidance continues to point to a dip in the mid latitude westerlies that will be favorable for Canadian air mass frontal passages. A cold front will move through Thursday but with very limited moisture in place. Weak sfc high pressure will build in with a cooler/drier Canadian air mass for Friday and early Saturday. A warming trend will briefly occur Sunday with south winds kicking back in ahead of another Canadian sfc cold front. Some potential for storms with that frontal passage will occur during the Sunday night-Monday time frame. Beyond Monday, temperatures look to be much cooler than normal, more fall like, with continued rain chances at times. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1144 PM CDT Mon Aug 31 2020 For the 06z TAFS...Convection has been holding to the southwest of the area across OK all evening. Should start to see this area of showers and embedded thunder move into southern Missouri overnight and begin to affect the forecast terminal locations. Will start to see ceilings/visibility lower into the MVFR category with the showers/storms and potentially into some IFR. The rain chances will continue into Tuesday, especially over far southern MO. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...DSA LONG TERM...|DSA AVIATION...Lindenberg
