.DISCUSSION... Issued at 203 PM CDT Tue Sep 16 2025
Upper ridging will maintain a mainly dry forecast through much of Friday. However, there is a weak inverted trough that is producing a few isolated showers and storms across the south half of the region this afternoon. Looks less likely for this on Wednesday, but can`t be completely ruled out.
An upper level wave across Wyoming today will gradually slide eastward and into the Midwest by Friday. Models vary on the evolution and placement by late week though, with the ECMWF further south and GFS/Canadian further north. The further north solution would likely mean less coverage and lighter QPF for the weekend if realized. Regardless of which solution pans out, it doesn`t look to be a drought buster by any means. Looking at the 72 hour probability from the LREF only gives us a 20-40% chance of >0.50" through Sunday night. Most likely outcome as it looks now is for most areas to remain in the 0.10" to 0.25" range, with localized higher amounts.
Additional rain chances may continue early next week, but model agreement isn`t great lending to less confidence. The ECMWF AIFS in particular is bullish hanging up a trough oriented from the Ark-La- Tex into the lower Ohio Valley and ramps up moisture transport giving us 1-2" of rain. This is the outlier solution at this point though.
Temperatures remain toasty through Thursday, although humidity levels remain tolerable so heat index values will be similar to or even a degree cooler than the actual temperature. Increased clouds on Friday should keep us several degrees cooler, although we may still reach hit 90 in some areas. This would be the 9th consecutive day of 90 in Paducah, which would be 1 shy of the September record of 10 straight days. Above normal temperatures continue this weekend into early next week, but generally in the mid to upper 80s. Looks like true Fall weather will remain on hold for a while longer.
