The episode as NWS EAX wrote it up.
On consecutive afternoons and evenings of October 8 and 9, several mini or low-topped supercells formed across NW Missouri. These storms did not produce much in the way of severe weather, aside from some weak and brief tornadoes. The damage was relegated to powerlines and tree damage.
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 Oct 8, 2:25 PM CST, 2 hours 29 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 325 PM CDT Mon Oct 8 2018 .Discussion... Issued at 324 PM CDT MON OCT 8 2018 The historically wet pattern that has persisted across the area since late last week is taking a bit of a breather this afternoon as the focus for showers and thunderstorms has shifted a bit further west into NE/KS/OK in the vicinity of a stationary front. A 35-40kt southerly LLJ has been persistent in that area today and has allowed storms to continue to fire out there. The storm motion has been from south to north mimicking the orientation of the LLJ. This should continue to be the case through the remainder of the afternoon keeping the bulk of precipitation to the west of the CWA (although Atchison Co. Kansas and northwestern Missouri will see the chance for thundershowers to sneak into those areas). Tonight the LLJ begins to veer to the SW and even shifts further east brings the chance for showers and thunderstorms back into the area. The western CWA will definitely see precipitation...heavy at times whereas the eastern CWA will see little if any precipitation overnight. Tomorrow into Tuesday night and Wednesday morning we will see a similar set up to today. The LLJ that moves into our area overnight will weaken during the morning with showers weakening in turn. The LLJ will then ramp up again late morning across eastern Kansas and showers and thunderstorms will begin redeveloping over those areas. Again, the western CWA will see the best chance for precipitation during the late morning and afternoon. As we get into tomorrow evening a upper level jet rounding the base of a upper level trough that will be moving into the western High Plains forcing a surface cold front toward the CWA. Strong forcing along the front will allow thunderstorms to develop. These storms are expected to quickly grow linear and given the shear there is the chance for storms capable of damaging winds. What is certain, is these storms will be efficient as PWATs will again be in the 1.75" range which is in the 99th percentile for the beginning of October. Rainfall totals for the remainder of the event will be between 2 to 3 inches along and west of I-35 and 1 to 2 inches east of I-35. As such, a flood watch has been issued for areas west of I-35 in northwestern Missouri and northeastern Kansas. The cold front should clear the area by Wednesday afternoon and a period of dry weather should prevail as surface high pressure moves into the region. Temperatures behind the front will be very fall- like with highs in the 50s by Thursday and Friday with lows in the mid 30s to lower 40s. Frost may be an issue but Wednesday and Thursday night. The next strong signal for rain approaching the area will be on Saturday and again rainfall could be heavy fortunately this system will be progressive and it will not be a prolonged rain event. Dry conditions should return for the second half of the weekend will cool temperatures continuing to prevail with highs in the 50s. && .Aviation...(For the 18Z TAFS through 18Z Tuesday Afternoon) Issued at 1230 PM CDT MON OCT 8 2018 A warm front is lifting north thru the terminals this afternoon bringing winds out of the SSE around 10kts. This will also force the showers north of the terminals and conds should remain dry thru midnight.
