GosselinWhat forecasters said that day
The local office's own words before this river flood warning went out, 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 this river flood warning went out at Jun 18, 6:08 AM CDT, 5 hours 35 minutes earlier. Its key messages:
- Aside from isolated/scattered showers today, largely dry conditions are expected through Friday.
- Opportunities for showers and thunderstorms exist Saturday through early Monday, with the highest chance on Sunday accompanied by a low threat of locally heavy rainfall.
- Temperatures will vary from near to below average through mid- next week.

Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 608 AM CDT Thu Jun 18 2026 .KEY MESSAGES... - Aside from isolated/scattered showers today, largely dry conditions are expected through Friday. - Opportunities for showers and thunderstorms exist Saturday through early Monday, with the highest chance on Sunday accompanied by a low threat of locally heavy rainfall. - Temperatures will vary from near to below average through mid- next week. && .SHORT TERM... (Through Late Friday Afternoon) Issued at 319 AM CDT Thu Jun 18 2026 A few showers and thunderstorms are expected to continue at times through daybreak across southeastern MO/southwestern IL until the front departs by around mid-morning, but weak convergence and displacement from the LLJ will limit coverage. A combination of weak mid-level isentropic ascent and strengthening FGEN will force additional isolated to scattered post-frontal showers, perhaps a rumble of thunder, late morning through the afternoon that sweep through the area. However, low-level advection of a drier and much cooler airmass will limit how much precipitation reaches the ground and is measurable. The highest chances of (light) measurable rainfall per the HREF are 20 to 40 percent near the I-70 corridor. Associated cloud cover and this cooler airmass will result in much cooler (10 to 15 F) high temperatures compared to Wednesday, in the mid-70s to low-80s F for most areas. A surface high pressure center will migrate into the CWA late tonight through Friday beneath gradual mid-level height rises. Resulting mostly clear skies and calm/light winds will allow low temperatures Friday morning to reach the mid-50s to low-60s. Patchy radiation and/or steam fog, mainly in river valleys, is possible with these temperatures flirting with forecast crossover temperatures and around 20 F cooler than river water temperatures. High temperatures will be warmer on Friday and around 80 to the mid- 80s F given strong insolation expected through only thin upper-level clouds, despite an absence of WAA during the day. Pfahler && .LONG TERM... (Friday Night through Wednesday) Issued at 319 AM CDT Thu Jun 18 2026 Late Friday through early Monday, upper-level northwesterly flow will transition to quasi-zonal across the Mid-Mississippi River Valley, providing one or more additional opportunities for showers and thunderstorms as moisture slowly returns with incremental northward advancement of a front and a series of upper-level shortwave troughs/perturbations pass. Ensemble model guidance has the greatest support for showers and thunderstorms in the late Saturday night through Sunday evening timeframe coinciding with a more prominent shortwave trough. There are also mixed signals for an MCS to initiate across the Central Plains late Saturday, arriving in the Mid-Mississippi River Valley or Ozarks on Sunday. Lower resolution global models have been struggling to resolve this MCS and its associated MCV partially due to suspected convective feedback issues, which introduces significant uncertainties on the longevity, track, and timing of the MCS and the influence of those factors on the overall surface and upper-level pattern. With the aforementioned uncertainties, the NBM interquartile high temperature range is also nearly 10 F on Sunday, spanning the low-70s to mid-80s F. It is also worth mentioning that although the chances of showers and thunderstorms are 70 to 90 percent throughout Sunday, it is unlikely that it will rain the entire day. With PW projected to exceed the 90th climatological percentile in addition to a potentially favorably oriented front and aforementioned MCS, there is at least a low threat of locally heavy rainfall Saturday night into Sunday. This threat is supported by a signal in the ECMWF EFI/SOT for extreme rainfall, but it has been highly variable from run to run and highest values are generally to the west of the CWA. Additionally, there could be some threat of severe weather, but this threat appears even more conditional and with lower confidence. Monday through mid-next week, global model guidance is in agreement that the front will shift back south of the CWA as upper-level flow also becomes northwesterly once again. As a result, temperatures will return back to below average and largely dry conditions will prevail. Pfahler && .AVIATION... (For the 12z TAFs through 12z Friday Morning) Issued at 608 AM CDT Thu Jun 18 2026 Dry and VFR flight conditions will exist most of the TAF period. Scattered showers are expected late this morning into the afternoon, mainly along/just north of the I-70 corridor. However, confidence is low in any categorical reductions at the terminals, although a stray lightning strike or two is possible. Late tonight/Friday morning, conditions could become favorable for some patchy river valley fog but confidence is not high enough to include at the juncture.
