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 6, 5:53 PM CST, 3 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 653 PM CDT Wed Aug 6 2014 .SHORT TERM...(This Evening through Friday Night) Issued at 402 PM CDT WED AUG 6 2014 Water vapor satellite imagery this afternoon shows a rather messy upper level pattern in place across the Nation with negative height anomalies to our east and positive height anomalies to our west, down stream from a ugly little cutoff circulation --shear axis?-- spinning over the Great Basin. Closer to home a shortwave trough is noted slowly shifting east through the northern and central Plains. An associated surface low is in central Kansas with a warm front extending east into Missouri; roughly along a St Joseph to Moberly line. Currently, convective activity is bubbling in eastern Kansas and is expected to spread east into Missouri late this afternoon and evening. For this evening and through tonight...the shortwave moving east across Kansas has bumped into an axis of high instability across eastern Kansas, where MUCAPE values of 3000+ J/KG are present. This has sparked storms in eastern Kansas, but limited shear -- 0-6KM values struggling to reach 30 knots-- has left the storms pulsing up and down. This should limit primary hazards with storms late this afternoon to damaging winds as individual storm cells collapse. This activity is expected to spread east late this afternoon and into the evening hours across western Missouri with the wind threat diminishing later in the evening. The slowly veering jet under the shortwave might be able to keep moisture focused across the Kansas-Missouri state line tonight, which could result in redeveloping storms across northeast Kansas and/or northwest Missouri late tonight. This could result in repeated rounds of rain, and with precipitable water values over 1 inch torrential rain may lead to some localized flooding issues. However, have held off on any kind of Flood Watch product though as basins in the region could stand to take a bit of rain before flooding. Thursday...convection is expected to be ongoing that morning as the left over complex of storms slowly slides east. This could keep a mix of showers and embedded thunderstorms percolating across Missouri through at least the first half of Thursday. More storms may bubble up through the day, but the focus for activity looks like it will have moved into eastern and southern Missouri likely resulting in castoff showers and storms through the afternoon as the upper level shortwave --to our west today-- finishes moving to our east. Friday...still more storms are forecast, but have backed off the POPs considerably. By Friday we should be west of the shortwave driving the activity tonight thru Thursday. This will leave the frontal boundary sweeping through today wallowing around to our south, so have trimmed POPs for the day Friday as isolated coverage is all that looks possible at this time. .LONG TERM...(Saturday through Wednesday) Issued at 402 PM CDT WED AUG 6 2014 Second half of the weekend remains unsettled as upper flow remains zonal with embedded shortwave troughs moving across the central plains. Deep moisture will continue streaming in from the Gulf of Mexico and models agree that additional shortwave troughs will ripple through the flow through the weekend. As we move into next week...the upper ridge over the Rockies will amplify and increase the meridional flow over the CWA. This will keep temperatures below normal early to middle next week and decrease the moisture and thus precipitation chances for Tuesday and Wednesday. && .AVIATION...(For the 00Z TAFS through 00Z Thursday Evening) Issued at 649 PM CDT WED AUG 6 2014 Thunderstorms and rain are ongoing at the terminals at this time, with more thunderstorms to the west of the terminals expected to effect them tonight. Occasional rain will prevail at the terminals for the next couple of hours before the next line of storms role in from the west. Have estimated time for the next round between 02Z and 04Z, though activity may last past 04Z. More storms may develop early Thursday morning, but confidence is too low to include in the TAF at this time. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE.
