Updated at 111 AM EDT Mon Oct 6 2025 - A cold front Tuesday into Wednesday will bring chances of rain and storms back to the region. - Temperatures will continue to be unseasonably warm; 5 to 10 degrees above normal. More seasonal readings are anticipated by the latter half of the week. && .DISCUSSION... Issued at 111 AM EDT Mon Oct 6 2025 Upper level ridging will become suppressed today, replaced by troughing across the northern tier of the country. Increased return flow and persistent Gulf moisture unleashed northward, will bring rain chances back to western and middle TN today. It`s possible a stray shower or sprinkle, much like yesterday for some, could occur this afternoon. For most, it will be another dry day with increasing clouds, humidity, and continued warmth. The approaching lowering heights aloft will bring a welcomed cold front to the region Tuesday into Wednesday. One more day of highs in the 80s until the rest of the forecast reads in the 70s, especially in the valley. Rainfall amounts will be greatest closest to Kentucky and West Virginia. QPF totals drop closer to the Southern Appalachians and southeast TN. It`s possible over an inch of rain could be seen from the upper plateau, valley, and into upslope areas of southwest VA. Small parts of the forecast area exhibit D0 on the drought monitor released just before the end of last month. Following the FROPA, Thursday and Friday, additional shortwaves may keep rain chances around. Once past that, it`ll be another dry weekend with much lower humidity and cooler temperatures under strengthening NE US surface high pressure and a closed low overhead. && .AVIATION... (06Z TAFS) Issued at 1220 AM EDT Mon Oct 6 2025 There are low chances for fog mainly TYS and TRI late tonight, and low chances for a period of MVFR cigs at CHA mainly during the mid/late morning into early afternoon. However, at this time those probabilities look too low to warrant their inclusion in the forecast, so will continue the VFR forecast for the period all sites. && .PRELIMINARY POINT TEMPS/POPS...
