The local office's own words before this special weather statement went out, 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 this special weather statement went out at Jun 20, 6:31 PM CDT, 1 hour 29 minutes earlier.
Area forecast discussion, Jun 20, 6:31 PM CDT, 1 hour 29 minutes before
Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 631 PM CDT MON JUN 20 2016 .Discussion... Issued at 246 PM CDT MON JUN 20 2016 Frontal boundary sagging south into the forecast area this afternoon and evening should provide the focus for scattered thunderstorm activity especially across northern Missouri. Although shear is weak sufficient instability in place for a few severe thunderstorms although coverage should be limited. Frontal boundary forecast to slow and stall near I70 overnight. Focus of LLJ will be mainly west of forecast area overnight, however with boundary extending across the region threat for storms will linger across northern Missouri for much of the night. Tomorrow morning the boundary begins to lift northeast as a warm front which should bring threat for convection gradually to an end during the day on Tuesday. Depending on progression of boundary on Tuesday afternoon there is a chance that thunderstorms could redevelop over far north central and northeast Missouri tomorrow. Otherwise upper ridging builds back into the area Tuesday afternoon and especially into the day on Wednesday. Wednesday should be the hottest day of the week as H8 temperatures >= +24C nose into northwest Missouri. Looks like a decent chance that heat index values will approach advisory levels on Wednesday particularly over the western part of the forecast area, so will need to see how convection over the next 24-36 hours plays out and then re-evaluate. Another upper level system moves across the northern Plains on Thursday dragging a surface cold front into the region. As a result a bit cooler conditions along with scattered thunderstorms can be expected for the end of the work week. Into the weekend a stronger upper level storm system will move through the northern Plains once again flatting the upper ridge somewhat and providing the threat for scattered convection. Temperatures this weekend should remain above normal for this time of year but not excessively hot. && .Aviation...(For the 00Z TAFS through 00Z Tuesday Evening) Issued at 630 PM CDT MON JUN 20 2016 Areas of storms pushing through KSTJ will depart the terminal within the next hour, and should stay east of all KC area terminals as they push south southeastward this evening. Opted not to mention even VCTS at KMCI/KMKC/KIXD for that reason; however, the frontal boundary the storms are associated with may drift near KC later this evening and make winds a bit variable for a few hours before returning to the south southeast. Areas of storms may redevelop after 09z tonight and could have a better propagation into the KC area, but due to the limited probability of these storms developing and making it south, have stuck with VCTS for now during the window that storms would be most probable if they do occur. Otherwise, mainly VFR conditions are expected. && .EAX Watches/Warnings/Advisories... KS...None. MO...None. && Discussion...Mitchell Aviation...Laflin
