A downstream Severe Thunderstorm Watch issuance appears unlikely given downstream stabilization. DISCUSSION...An MCS continues to progress eastward across central IA, and is approaching the eastern bounds of Tornado Watch 669. East of the watch bounds, surface temperatures have cooled into the lower 70s F, with buoyancy struggling to build farther to the east. Since severe gusts have also not been observed with the progressive portion of the line for the past one and a half hours, the current thinking is that the severe threat should diminish. Therefore, while a severe gust or two still cannot be ruled out, the threat should be isolated enough to preclude a downstream Severe Thunderstorm Watch issuance. ..Squitieri/Smith.. 09/15/2026 ...Please see www.spc.noaa.gov for graphic product...
