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 St. Louis, MO wrote its last area forecast discussion before the first event at Jul 6, 5:42 AM CST, 4 hours 3 minutes earlier.
Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 642 AM CDT WED JUL 6 2016 .SHORT TERM... (Through Late This Afternoon) Issued at 357 AM CDT Wed Jul 6 2016 Ongoing MCS to our north with its eastern section moving thru northern IL dropping to the south-southeast. Current indications are that this should hold together long enough to impact our far northern CWA and much of the CWA in Illinois during the early to mid morning hours. Severe threat should be minimal with this but will continue to monitor. Another MCS over in KS also bears watching, with the MCV from this activity expected to track eastward into our region later this morning and thru the afternoon. HRRR and our local WRF models picked up on this feature the best and supports likely PoPs or greater for much of our region from late morning thru much of the afternoon as it tracks west to east. Temperatures will be very conditional on the rain and become increasingly uncertain with time but should peak in the eastern CWA around midday or early afternoon with dropping temps with the increasing clouds and approaching rain, while will be stunted in the west this morning with some recovery in the mid to late afternoon. Favored max temps on the cool side of MOS. Heat index values look to edge around 100F for many areas near and south of Interstate 70 at some point today but not enough for an Advisory given what looks to be the very brief likelihood of the attainment of these heat index values and uncertainty. TES .LONG TERM... (Tonight through Tuesday) Issued at 357 AM CDT Wed Jul 6 2016 Tonight - Thu Precip assoc with MCV should exit sthrn IL this evng with much of the overnight prd dry. Subtle short wave embedded in the zonal flow will move out of the nthrn Plains this aftn and into IA/MN this evng. This should initiate TSTM dvlpmnt to our NW. This activity will drop SE overnight and may approach the nthrn FA well after midnight. The eventual sthrn extent of this activity and assoc outflow bndry will determine convective trends on Thu since the area will be largely void of any other forcing mechanisms. Any activity that does dvlp is expected to be sparse due to a substantial cap with 700mb temps of +13C to +15C. A dvlpng short wave across the Dakotas will be our next WX maker for the end of the week. Thu should be the hottest day of the week. 850mb temps of +22C to +25C support high temps in the mid 90s to near 100. I think plenty of BL moisture will help keep temps from getting out of hand and am expecting highs in the low/mid 90s...though there is the potential for temps to be a category higher. Regardless...highs in the 90s and Dps in the mid 70s will produce HIs above 100 across the entire area and possibly 105+. A headline may very well be needed. Thu Night - Fri Night Any convection that was able to dvlp drng the aftn should fade after 00Z. The aforementioned short wave will track from the Dakotas on Thu to the wrn Grt Lks Thu night into Fri mrng. This feature will lift a SFC low from IA Thu night to the Grt Lks by Fri night. A cold front assoc with the SFC low will drag thru the FA from Thu night thru Fri. There are timing differences...but the general scenario is for convection to fire along the front to our N/NW drng the late aftn and evng and then sink S/SE along with the front or at least what will become the effective front. Expect this activity to move into the wrn/nthrn CWA around midnight. Convection should continue to move SE drng the early mrng and then should slowly fade away towards 12Z. Front should progress to the I44 corridor in MO and I70 in IL by 18Z before addntl convection dvlps drng the aftn. Front is expected to clear the far sthrn zones across SE MO Fri evng...tho precip chances will continue for SE MO due to proximity to the bndry. SFC high centered across Hudson Bay builds into the region overnight. Temps on Fri could be tricky depending on evolution of mrng convection. Residual cloud cover...outflow bndrys and frontal timing will play an important roles. Sat - Sat night Fri's FROPA will introduce a cooler and drier air mass for the wknd. Upper heights begin to rise as a ridge progresses E from the Plains. This will cause the front to stall along the AR/MO border over the wknd so shtrn zones will continue to have diurnally driven precip chances. Guidance has come into better agreement depicting what appears to be an MCV traversing sthrn MO Sat. There is still some discontinuity on exact track of vort max but it appears to have shifted S/SW some. Potential clouds and precip may limit high temps...esp across the far sthrn CWA on Sat. Sun - Tue Upper ridge will be well established early next week. Sthrly flow will begin by Sun. This will allow normal summer time conditions to return as the air mass slowly modifies with limited chances for diurnally driven convection. 2% && .AVIATION... (For the 12z TAFs through 12z Thursday Morning) Issued at 642 AM CDT Wed Jul 6 2016 First batch of storms from the north edging UIN currently and ability to edge the STL metro sites looking more doubtful with western edge eroding as it pushes south. Will need to be monitored but due to it being in doubt currently, have no mention for this. Second batch of storms from the west are filling in a bit more of late and are still on track to move thru COU between 15-18z and STL metro sites between 17-20z, with UIN again being on the northern edge. After this, storm chances look small, small enough to preclude mention in the TAFs, but indications continue to favor another storm complex dropping from the northwest at the very end of the valid period or just beyond. Otherwise, southerly surface winds and mainly VFR conditions will prevail at the TAF sites thru the valid period. TES && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX
