694 FXUS63 KPAH 122249 AAA AFDPAH Area Forecast Discussion...UPDATED National Weather Service Paducah KY 549 PM CDT Tue Aug 12 2025 .KEY MESSAGES... - Typical summer-time heat and humidity will continue through the work week. Daily highs will primarily be in the upper 80s to lower 90s through Thursday. - Showers and thunderstorms are expected through Wednesday night for most areas, before decreasing chances on Thursday focused on mainly the southern half of the region. - Dry weather is expected Friday through Monday with temperatures warming into the mid 90s. Heat index values will rise into the triple digits. && .DISCUSSION... Issued at 304 PM CDT Tue Aug 12 2025 Upper level troughing extends across the north central U.S. this afternoon and is resulting in scattered showers and storms across portions of the area. Can`t rule out brief gusty winds in some of the stronger storms but severe weather is not expected this afternoon. The upper trough and a surface boundary across the region on Wednesday will support continued chances of rain/storms. By Thursday, the front will move east of the area with northerly winds as high pressure builds in from the north. Most of the area will likely remain dry with slight chances across mainly the southern half of the region. Heights build across the region late in the week and especially over the weekend leading to increasing temperatures and dry conditions. High temperatures over the weekend will rise into the mid 90s with heat indices likely climbing into the triple digits. Localized heat indices may approach 105 degrees Saturday and Sunday. Towards the end of the extended period, the ridge shows signs of breaking down. This may lead to a slow increase in convection but temperatures will still remain hot with highs remaining in the mid 90s. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 548 PM CDT Tue Aug 12 2025 Scattered convection will remain a factor through the next hour or two, but should start to decrease quickly after sunset. A stray shower or two is possible in the overnight as a weak front moves in from the northwest but operational impacts appear too unlikely for TAF mention with this package. Moisture is pooled ahead of the front in a way that would support fog formation but mid and upper level cloud cover may prohibit sufficient cooling. VFR conditions then appear likely through the day Wednesday. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. && $$ DISCUSSION...AD AVIATION...JGG
