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 Jun 9, 11:41 AM CST, 1 hour 54 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 1241 PM CDT Sat Jun 9 2018 ...Update to Aviation Discussion for 18Z Tafs... .SHORT TERM...(Today and tonight) Issued at 157 AM CDT Sat Jun 9 2018 Isolated showers and storms will be possible today mainly across the eastern Ozarks generally east of Highway 65. A weakening upper level ridge will push eastward through the day with a few weak short waves moving through the upper level flow. The combination of the shortwaves, the moist airmass in place and daytime heating will be the fuel for any storms that can develop. Afternoon temperatures will again climb into the upper 80s to lower 90s. No organized storms are expected but a strong storm would be possible. One limiting factor will be the southwesterly surface flow that will begin to bring some slightly drier air originating from west Texas. This is the primary reason storm chances are much smaller across the Western Ozarks and southeast Kansas. The drier air will continue to filter into the region tonight and push rain chances eastward as it does. The ridge will also help with shifting the rainfall east. .LONG TERM...(Sunday through Friday) Issued at 157 AM CDT Sat Jun 9 2018 Sunday into Monday morning looks dry as the upper ridge and dry airmass remain over the area. This may be the only period for next week that does have near zero chances for rain however. A cold front will move across the plains and through the Ozarks Monday evening into Tuesday morning. This will bring chances for showers and storms to the area. The front lift will be weak however and strong to severe storm development will be limited at best. The good part is that most of the area could see some rain. As the front sags south, it will stall and hang up along the Missouri/Arkansas line. The upper level flow is also expected to become zonal or west to east once the front begins to stall. This combination will allow for a period of wet weather across the region through the end of next week as any short waves moving through the upper level flow would help to develop showers and storms. There appears to be several shortwaves in the models through the week with a least slight chances for rain every day. The later in the week the chances are less confident as models do begin to have diverging solutions, but the general trend for rainfall remains. Temperatures will remains in the upper 80s to lower 90s each day for highs Through this weekend and into next weekend as the overall flow, both surface and upper level keep the region summer like despite the chancing upper level flow and a more southerly vs southwesterly surface flow. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1240 PM CDT Sat Jun 9 2018 South to southwesterly winds and VRF conditions will occur across the area through the the TAF period. Isolated storms will be possible this afternoon, but this activity should remain east of the TAF sites. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
