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 Kansas City, MO wrote its last area forecast discussion before the first event at Sep 30, 10:52 PM CST, 1 hour 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 1152 PM CDT SUN SEP 30 2012 ..UPDATED AVIATION DISCUSSION... .DISCUSSION... /334 PM CDT Sun Sep 30 2012/ In split upper flow, broad trough continues to slowly drift northeastward out of the Arklatex region this afternoon. This feature will slightly deepen through Monday as a strengthening upper jet rounds its base, though any precip will be to the east of the upper trough axis, well to the east of the forecast area. Meanwhile a large area of upper diffluence to the northwest of the upper trough will continue to bring a surge of thick cirrus to the region overnight, so overnight lows were raised a degree or two. For Monday, northern stream shortwave will track across the Upper Midwest, with an associated tropospheric PV anomaly that will dive southeastward and gradually phase with the one over the Mid South. The result will be a weak cold front that will track through the area mid to late morning Monday. A lack of deep moisture and instability still looks to be the main prohibiting factor behind any kind of appreciable precip with this front, so continued to keep PoPs limited to slight chance for now. However, if BL moisture can increase enough, as suggested by the NAM, then modest frontal convergence within a seasonably deep boundary layer should allow for at least scattered showers and possibly a thunderstorm in the afternoon, so will need to see if PoPs should be increased in later forecasts. Aforementioned phasing of the upper tropospheric PV anomalies on Tuesday will lead to a deeper upper trough digging into the Midwest and Ohio Valley, and a slower eastward progression of this trough than models had indicated earlier. Therefore held on to cloud cover a bit longer Monday night and Tues and had to drop temps several degrees on Tues due to a later onset of return southerly flow into the area. A very brief period of ridging on Wednesday should still allow temps to climb into the upper 70s and lower 80s before a much deeper trough and associated cold front move into the Plains early Thursday. Medium range models, which were earlier in decent agreement with this feature, have taken diverging solutions now with the ECMWF trending quite a bit weaker and faster with this system while the GFS has been holding on to a deeper and more meridional trough. This introduces quite a bit of uncertainty into the forecast for the end of the week with the ECMWF holding on to quasi-zonal upper flow and an active precip pattern while the GFS points to deep high pressure across the Plains. Will therefore hold on to a blended solution for now bringing slight chance to low-chance Pops into the area Friday night and Saturday on account of the ECMWF. Either way temps next weekend look rather cool with highs on Saturday that may not make it out of the 50s. Hawblitzel && .AVIATION... For the 06Z TAFs...VFR conditions will continue. Extensive high level cloud cover associated with large upper trough over the Lower MS Valley will remain in place into Monday. A cold front will push through the terminals around noon time. Northerly winds will increase with gusts lagging a few hours after frontal passage. The gusty winds will linger into early Monday evening before subsiding. MJ && .EAX WATCHES/WARNINGS/ADVISORIES...
