The remnants of Tropical Cyclone Gordon have moved out of the region, so the Flash Flood Watch for a portion of south central Illinois has been cancelled. As Gordon moved through the region, it brought up to 6" of rain to some locations, and widespread areas over 3". The cold front that brought additional areas of rain to the forecast area over the last several days will remain in place this afternoon and into the evening. This has resulted in additional areas of light to moderate rain, which should also last into the evening. Up to an additional 1/4" of rain is possible with these showers, but no flash flooding is expected. All rain should end by Sunday morning. $$ BSH

The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Sep 6, 12:21 AM CDT, 3 hours before
Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 1221 AM CDT Thu Sep 6 2018 .UPDATE... Issued at 839 PM CDT Wed Sep 5 2018 Have updated PoPs overnight based on latest mdl guidance. Believe that ongoing SHRA over NE MO into west central IL will diminish slightly over the next couple of hours as low level forcing weakens. However, as the LLJ increases across portions of central MO around Midnight, expect precip to refocus over this region and spread newd into NE MO and west central IL and persist into Thurs morning. A concern for overnight will be precip amounts. While expecting a nearly continuous rain is expected from portions of central into NE MO and west central IL, it appears that thunder will be fairly limited overnight. This shud reduce the threat for heavy rainfall. This in turn will be offset by training. Do not feel confident enuf in a Flash Flood threat to go with a watch at this point. However, the rainfall overnight will certainly prime the region for a flood threat later this week in addition to the current river flood threat. Tilly && .SHORT TERM... (Through Late Thursday Afternoon) Issued at 403 PM CDT Wed Sep 5 2018 The cold front extending SW from a surface low in SE Canada continues it's march toward the Mid-Mississippi Valley. The front is just beginning to push into the CWA, and is generating widespread showers and scattered thunderstorms. The front will stall out across NE MO and west central IL this evening, and will remain the focus for precip chances through the night. Meanwhile, isolated to scattered convection across east central MO and SW IL will persist through the afternoon, tapering off as we lose diurnal heating. Upper level flow will remain fairly weak tomorrow, keeping the baroclinic zone laid out across NE MO and west central IL. Meanwhile, Tropical Depression Gordon will continue its push NW, allowing for deep moisture to build into the region, pushing PWATs toward 2" across the area. The front and Gordon will likely result in a couple of focuses for precipitation on Thursday. First of all, precip should continue along the stalled front across NE MO/WC IL. Secondly, increasing column moisture coupled with the outer reaches of Gordon should allow precip chances to increase in SE MO/SW IL. CAPE is somewhat limited, but certainly sufficient to support embedded storms. BSH .LONG TERM... (Thursday Night through Next Wednesday) Issued at 403 PM CDT Wed Sep 5 2018 Upper level flow will turn a bit more southwesterly on Friday as a broad trough moves into the Great Plains. Meanwhile, Gordon will continue to push to the NW while high pressure simultaneously pushes south into the Upper Mississippi Valley, shunting the weakening baroclinic zone a bit farther south. The combination of increasingly dynamic upper level flow, the stationary front, and the remnants of Gordon will keep precip chances in place across the area. From 06-18z Friday, both WPC guidance and superblend are painting over 2" of QPF, where as the raw synoptic models top out around half that much. With PWATs around 2" during that period, efficient rain makers are expected and I'm fairly certain the model amounts will be exceeded. That said, 2" seems a little excessive for that period, so I tried to split the difference between WPC/superblend and the raw models. The previously mentioned upper trough will continue its push east, catching the TD Gordon as it reaches NW AR/SW MO early Saturday morning. At that point, Gordon's track will curve to the NE and move through southern MO on Saturday. 12z GFS, NAM, and Euro bring the center of Gordon just south of St Louis on Saturday night, with highest precip totals focused north and west of the low track. At this moment, confidence is high that quite a bit of rain will fall between 06z Saturday and 06z Sunday, and this will be when the greatest chance for flash flooding will occur. That said, uncertainty remains with regards to where the heaviest axis of precipitation will occur, so we will hold off on a flash flood watch for the time being. High pressure will build into the region for the early part of next week, resulting in mostly dry conditions. Temperatures will be quite a bit cooler than what we've see lately, with highs in the upper 70s on Monday, pushing into the low to mid 80s by Wednesday. BSH && .AVIATION... (For the 06z TAFs through 06z Thursday Night) Issued at 1210 AM CDT Thu Sep 6 2018 Main updates were to delay onset of lower cigs at KCOU/KUIN. A fair amount of uncertainty exists regarding cigs, especially at KCOU. IFR cigs currently exist just west of KCOU. Believe at least some MVFR cigs will develop into KCOU before lifting north of the area overnight as the precip pulls northward. At KUIN...once the lower cigs move into the area, these cigs shud remain in place until Thurs morning. The timing of these cigs lifting may be too quick as well. SPECIFICS FOR KSTL/KSUS/KCPS: Little change overall. Light winds expected. Dry and VFR expected, although, isod to sct TSRA are expected Thurs afternoon. Coverage is too low to go with more than a VCTS attm. Tilly && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX
