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 Aug 9, 5:18 AM CST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 618 AM CDT Fri Aug 9 2013 .SHORT TERM...(Today through Sunday Afternoon) Issued at 324 AM CDT FRI AUG 9 2013 The overnight MCS parade continues albeit a bit further south then in previous nights. The current radar image shows a well developed complex of thunderstorms across much of northern Oklahoma and moving northeastward into southern Kansas. Model soundings over the area continues to show a dry wedge between 750mb-900mb. So, as this complex continues to push northeast towards the CWA this morning it will have to overcome this dry wedge. 00Z short and medium range model solutions do not appear to be handling the location of the MCS this morning. However, using hi-res short term models and the GFS which is handling this system reasonably well, have showers moving into the southern CWA this morning spreading slowly northward through the day. The best chance for showers will be across the southern CWA where chance to likely POPs reside. Further north along the I-70 corridor expect just occasional light showers so only have slights in the going forecast there. With copious cloud cover expected today, held highs mainly in the lower 80s. A cold front will drop into the area late this afternoon/evening. frontal passage should remain dry as moisture will continue to be pooling along the stationary boundary to the south extending from the southeastern MO to southeastern OK. It is this stationary boundary which again will be the focus for MCS development again tonight. This stationary boundary will keep the southern CWA in play for showers again tonight so continued slight chance to chance POPs there. Saturday's precipitation chances will hinge on the location of the stationary boundary to the south. Most activity will remain south of the area however model solutions that are furthest north with this boundary paints precipitation across the southern CWA. Also, of interest is surface of high pressure trying to build into the area from the Upper Midwest trying to undercut the precipitation. As such have continued slight chance POPs across the south on Saturday. Highs will be in the low to mid 80s with the warmer temperatures across northern Missouri where cloud cover will be more of a scattered nature. Sunday, skies should be mostly sunny as the stationary boundary will have shifted far enough south to not impact the area. However, an upper level shortwave will be moving into the Plains Sunday afternoon on the lee side of an upper level ridge which will reside over the Rockies. Sunday, however, should remain dry as this shortwave should hold off on impacting the area until Sunday night. Highs Sunday will be in the mid 80s. .LONG TERM...(Sunday Evening through Thursday) Issued at 324 AM CDT FRI AUG 9 2013 Forecast for next work week will see a combination of wet and dry days with below normal temperatures. Late in the weekend, Sunday night, another in a series of significant troughs that will drop through the Canadian Plains into a trough that will come to dominate the eastern CONUS by the middle of next work week. This prevailing pattern will keep a northwest flow in place across the northern and central Plains through next week. With a rather static pattern in place across the Plains, forecast expectations haven't changed much. The prevailing trough to our east should help keep occasional cool air intrusions heading south across the Lower Missouri River Valley through much of next week. This should keep temperatures running below normal for August, with highs ranging from around 80 to the mid 80s through much of the work week. Otherwise, best potential for rain in the dominate northwest flow currently looks confined to Sunday night through Monday as the Canadian shortwave trough digs into the east CONUS. The expansion of the east CONUS trough will likely send a weak boundary south into the Plains early Monday, which will settle to the south over the following days. && .AVIATION...(For the 12Z TAFS through 12Z Saturday Morning) Issued at 617 AM CDT FRI AUG 9 2013 Showers and isolated thunderstorms across east central Kansas and west central Missouri are continuing to lift slowly northeastward this morning. Showers will remain south of the terminals this morning however a few showers may develop this afternoon in the VC of MKC and MCI. Otherwise, cigs should remain VFR with bkn-ovc mid level clouds between 6-10kft through the TAF period. Winds through the period will be light out of the northeast. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && SHORT TERM...73 LONG TERM...Cutter AVIATION...73
