NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jul 8, 2:29 AM CST, 1 hour 1 minute earlier.
Area Forecast Discussion National Weather Service Saint Louis MO 329 AM CDT FRI JUL 8 2016 .SHORT TERM... (Through Tonight) Issued at 308 AM CDT Fri Jul 8 2016 A number of questions remain regarding thunderstorm evolution thru the period. A cdfnt continues to approach the region early this morning. Ongoing convection is expected to gradually sink swd as the LLJ continues to veer early this morning. While the main effective boundary shud be south of the CWA this afternoon, enuf instability is expected along and ahead of the cdfnt to pose a threat of redevelopment. With the lack of better forcing, have kept only slight chance PoPs along the cdfnt for now. More uncertainty remains for this evening as mdls suggest that a s/w resulting from ongoing convection over the central Plains will push ewd today. Guidance is in fairly good agreement with any convection dissipating before reaching the CWA this afternoon, but any resultant outflow may provide a focus for redevelopment tonight. Location and timing is uncertain attm and have kept PoPs on the lower end for now. As for temps, have trended twd the warmer guidance for most of the area today. The bulk of the convection shud exit the area this morning with clouds dissipating leaving ample insolation for this afternoon. Tilly .LONG TERM... (Saturday through Thursday) Issued at 310 AM CDT Fri Jul 8 2016 (Saturday through Sunday) The cdfnt shud push south of the CWA by Sat, however, not very far. Will keep chance PoPs across the srn portions of the CWA because of this. NW flow aloft returns with MCS activityreturning Sat night and into Sun. Have kept PoPs low for now due to uncertainty in placement, but if trends continue, will need to increase across the srn third of the CWA. Temps will be cooler thru the weekend with 850mb temps in the mid to upper teens. (Monday through Thursday) Mdls suggest a fairly active pattern will continue thru the extd period. Mdls are in good agreement with upper ridge building into the region early in the period, before becoming zonal by mid week or so. The above mentioned cdfnt will lift back nwd as a wrmfnt with the thermal ridge building into the area. Mdls do prog 850mb temps in the 20-22C range during this time, but have kept temps in the lower 90s due to a weak cap and mdls suggesting precip possible each day. Chances for a cdfnt arriving over at least nrn portions of the CWA increase mid week and beyond. Have increased PoPs for the remainder of the forecast period. Tilly && .AVIATION... (For the 06z TAFs through 06z Friday Night) Issued at 1147 PM CDT Thu Jul 7 2016 Scattered showers and thunderstorms wil affect areas mainly along and south of I-70 for the rest of the night. Some isolated storms are possible further north, but they should be few and far between. Any storm that directly impacts an airport will be capable of producing brief heavy rain which will likely reduce the visibility to 2 miles or less. Additionally, if the sky clears out after the storms move through a particular area, fog is likely to develop. Don't have a lot of confidence that there will be much fog due to extensive high cloud cover from storms west of the area...but it is possible. Any fog that develops should dissipate within an hour or two of sunrise. Specifics for KSTL: Scattered showers and thunderstorms will be in the vicinity of the terminal for at least the next 3 to 4 hours. Any cell to directly impact the terminal could produce IFR vsbys in heavy rain. Think the more widespread rain currently over central Missouri will miss the terminal to the south. Should see VFR flight conditions prevail outside of thunderstorms. There could be some fog before sunrise if the sky clears out, but I think this is unlikely.
