The episode as NWS LSX wrote it up.
Isolated storms developed across the area. Some of the storms produced damaging winds. Also, a landspout type tornado briefly touched down in a field just south of Belleville, Illinois.

Area Forecast Discussion National Weather Service Saint Louis MO 410 PM CDT MON JUN 13 2016 .SHORT TERM... (Through Tuesday) Issued at 359 PM CDT Mon Jun 13 2016 (Tonight) Isolated to widely scattered showers and thunderstorms are expected to drift northeastward and slowly weaken this evening. Expect most of the late evening and overnight hours to be dry (similar to the past couple of nights) though activity may linger a bit longer due to some semblance of weak low-level warm/moist advection. Temperatures will be similar to the past couple of nights as well with much warmer conditions than normal for mid June. Lows in the 70s for nearly everyone with the exception of eastern Ozarks which should dip down into at least the upper 60s. (Tuesday) Unclear picture for tomorrow but in general should be less coverage of showers/storms as mid/upper level ridge rebuilds slightly into the mid-Mississippi Valley. Maintained some low PoPs for some areas mainly for continuity sake. Will be an unstable atmosphere with only small capping...but little to nothing to really focus any convection as weak warm front should be northeast of CWA. In addition...that boundary across the CWA today is fairly diffuse already and so far this afternoon has failed to produce much in the way of convective coverage. Main story for tomorrow will be the heat and humidity. Raised high temperatures a degree or two on Tuesday due to less expected cloud cover and chances of storms. In addition...dewpoints will be up a couple of degrees compared to this afternoon which will combine with highs in the low to mid 90s to produce max heat index values of 100-105 in some locations. Gosselin .LONG TERM... (Tuesday Night through Next Monday) Issued at 359 PM CDT Mon Jun 13 2016 A shortwave moving through the plains will bring a chance of SHRA/TSRA to the region on Tuesday night. Forecast instability and shear parameters are sufficient to support organized severe wx, although the chances of severe wx appear to be higher farther west of the CWA. 13/12z runs of the GFS/ECMWF/GEM remain similar to yesterday. The aforementioned shortwave plows into the upper ridge and then tracks southeastward through the Great Lakes towards the east coast. A slight westward shift was noted in the track of the mid/upper low compared to ydy's runs, and the 13/12z GFS output at 00z Thu now begins to resemble its previous solution which involved a cutoff low retrograding through the Ohio Valley towards AR/OK. The inter- and intra-model disagreement-- whether, when, and where the shortwave becomes cut off from the prevailing flow near or downstream of the ridge axis-- appears to be caused by slight shifts in both the track of the shortwave and the position of the upper ridge axis. These small shifts lead to slightly different solutions which make a big difference in the fcst temps and precip chcs for MO/IL. Following the solutions depicted by the current model suite, the central CONUS ridge builds into Canada during the middle of the week. The aforementioned shortwave which moves through the Great Lakes will also drape a boundary across the region. High pressure building into the Great Lakes behind the departing low pressure system will push cooler and drier air into the region, acting to sharpen the boundary and push it farther to the west. Meanwhile, the mid/upper ridge continues to build and eventually spans nearly coast to coast by 12z Sun, although it flattens in response to a series of disturbances moving through Canada. This means that warm and humid conditions will continue through at least Wed/Thu until the back-door cold front moves through on Friday, bringing a drier air mass into the region for next weekend. With warm and humid conditions expected to persist for most of the week, attention then turns to the potential for heat headlines. Heat Advisories may be issued for either 1) max heat index of 105+ F on a single day, or 2) max heat index of 100+ F for 4+ days. There are a handful of grid points with calculated heat index values of 105 on Tue and Wed, however these values are not widespread enough over any single county to warrant a Heat Advisory. Likewise, there are many locations which may reach 100+ F for three of the four days between today and Thursday (a different set of 3 days depending on location). No headlines will be issued with the afternoon forecast package. Kanofsky && .AVIATION... (For the 18z TAFs through 18z Tuesday Afternoon) Issued at 1237 PM CDT Mon Jun 13 2016 Getting some diurnal cumulus and some weak echoes now starting in the terrain of the eastern Ozarks. Expected further development over the next few hours though coverage looks isolated to widely scattered. Maintained VCTS for late this afternoon/early this evening at all terminals just pushed it back an hour. For late tonight and on Tuesday...expect dry weather though cannot rule out a few storms anytime but chances look less than this afternoon/evening. Specifics for KSTL: Maintained VCTS for late afternoon/evening at Lambert Field...just delayed an hour as cu has just developed across the eastern Ozarks over the past hour. Storms should gradually shift northeastward and weaken overnight so expect dry conditions after this evening through the day on Tuesday. Winds will be light/variable this afternoon before becoming light out of the SSE tonight and on Tuesday. Gosselin && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX
