NWS Paducah, KY wrote its last area forecast discussion before the first event at Aug 5, 12:17 PM CST, 4 hours 3 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Paducah KY 117 PM CDT Tue Aug 5 2025 .KEY MESSAGES... - Isolated to widely scattered thunderstorms will continue through late this afternoon. - Locally dense fog is possible early Wednesday morning. - Dry conditions are forecast Wednesday through this weekend, with a small (15-20%) chance of thunderstorms forecast Monday. - Temperature and humidity levels will remain close to seasonal averages through the forecast period. && .DISCUSSION... Issued at 116 PM CDT Tue Aug 5 2025 Upper-level troughing over the eastern CONUS will gradually shift east of the region as surface high pressure and mid- and upper- level heights increase from the west. This means the ongoing isolated to widely scattered convection across the region will likely be the last day with mentionable precipitation chances until early next week. One thing to watch tonight will be for locally dense fog development, as low temperatures across the region will fall near or below crossover temperature thresholds. Temperature and humidity levels will remain near typical values for August throughout the next seven days. As the surface high pressure translates east of the region late this weekend into Monday, small precipitation chances return to the forecast as model guidance hints at the arrival of some enhanced tropical moisture from the Gulf, which will aid in isolated thunderstorm development. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1204 PM CDT Tue Aug 5 2025 SCT-BKN low VFR to MVFR cumulus decks will gradually lift to VFR by 20-21z. Widely scattered showers and thunderstorm development will continue through this afternoon before diminishing. Fog development is likely again late tonight (mainly in the 06-13z window), with MVFR to IFR restrictions expected at all terminals. Winds will be light and variable this afternoon, becoming calm overnight. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. && DISCUSSION...DWS AVIATION...DWS
