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 Wichita, KS wrote its last area forecast discussion before the first event at Sep 3, 2:19 AM CST, 2 hours 15 minutes earlier.
Area Forecast Discussion National Weather Service Wichita KS 319 AM CDT Mon Sep 3 2018 .SHORT TERM...(Today through Wednesday night) Issued at 319 AM CDT Mon Sep 3 2018 Water vapor imagery shows a slow moving piece of shortwave energy near the four corners region with a very moist mid and upper connection extending down into the eastern Pacific. Not much in the way of features to lock onto at the surface, with moist southeasterly flow across the central and southern Plains. Main concern for today and tonight will be another round of heavy rainfall. Water vapor imagery also shows an impulse approaching the Arklatex region that is expected to lift northwest today and tonight. There is good model agreement in PW values increasing to over 2" as this wave approaches late this afternoon. Current thinking is that current showers and storms will slowly wane as sunrise approaches. Should see a lull in activity this morning into the early afternoon hours with an increase in showers and storms around or after 20z in the same overall area we have seen storms the last couple of days, which is generally west of Highway 14. It appears the main driver allowing showers and storms to keep regenerating in this area is a southerly upper jet that hasn't moved in a few days, which places areas west of I-135 in the right entrance region. Severe storm chances don't look as good this afternoon and this evening as they did the last couple of days, as we lose the extreme instability and deep layer shear drops off slightly. So feel heavy rain and flooding will be the main threat. Showers and storms should increase in coverage overnight as the upper impulse lifting out of the Arklatex region helps increase and focus mid level moisture transport. Activity should slowly work east late tonight, at least making it as far as the Turnpike. Scattered showers and storms are expected to remain in place for Tue as mid-upper level moisture connection remains in place along with plenty of upper diffluence. There is good model agreement that a shortwave trough will slide across southern Canada and will allow a cold front to push south into the central Plains Tue night. Front is expected to extend from eastern Nebraska into west-central KS by 06z Wed and will keep high shower and storm chances around. Front is expected to try and move through the forecast area Wed but confidence is low on how far south the front makes it. Nevertheless, this boundary will keep showers and storms around Wed into Wed night .LONG TERM...(Thursday through Sunday) Issued at 319 AM CDT Mon Sep 3 2018 Both GFS and ECMWF agree on tracking another slow moving impulse out of the 4 corners region and across KS Fri into Sat. This feature will keep likely POPS around for Thu into Fri with a gradual decrease from west to east on Sat. By Sat afternoon, only southeast KS should be seeing rainfall. Not out of the question additional flash flood watches maybe needed as confidence increases on where the more intense showers and storms will setup. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1219 AM CDT Mon Sep 3 2018 Convective trends are still the main issue. VFR conditions expected outside of storms. Main swath of SHRA/TSRA will continue to affect the area between KGBD-KHUT and KSLN for the first several hours of the forecast. Consensus suggests that precipitation should wane around daybreak. Weak capping should result in isolated storms in the afternoon once again with coverage increasing in the evening. Unfortunately, there is little if any model consensus exactly where/when this be, making it challenging to fine tune the later part of the forecast period. -Howerton && .PRELIMINARY POINT TEMPS/POPS...
