Area Forecast Discussion National Weather Service Morristown TN 107 PM EDT Sat Aug 2 2025 ...New DISCUSSION... ...New AVIATION DISCUSSION... .DISCUSSION... Issued at 106 PM EDT Sat Aug 2 2025 Key Messages: 1. Seasonably cool temperatures continue through the first half of next week. We'll be close to normal by the back half though. 2. Rain chances continue through much of the forecast period as a broad mid/upper trough lingers over the eastern U.S. Discussion: Broad troughing overhead or slightly to our north, along with an inverted surface trough across the TN valley, will continue through the weekend lending itself to continued rain chances for much of the area and continued below normal temperatures. Mid level flow remains weak, so some isolated flash flooding will continue to be of concern due to slow moving storms, but severe chances are low overall. Regarding Sunday PoPs, the inverted trough shifts west some, and SELY H85 flow becomes more pronounced over the CWA. These factors could act to dry things out locally and shift the focus of rain further west, so PoPs may be somewhat overdone. However, it seems most probable that rainfall would shift more towards the plateau and away from our Virginia counties and far northeast TN, as opposed to completely out of our CWA. As such, left the NBM output in the forecast for now. Monday through the midweek timeframe a sharp upper trough develops over the mid and lower Mississippi Valley then shifts east into the middle Tennesse area, remaining there through the end of the period. There's some hints of rising heights over the northeastern part of the CWA in some guidance as the trough digs over the Mississippi valley, which could mean that PoPs are overdone at least in parts of our area Mon/Tue. But the general trend of keeping rain chances in the forecast through the end of the period for most of the CWA seems to be the right call. That upper trough isn't particularly strong and doesn't lead to any kind of frontal passage and air mass change, so at the very least we'd have diurnally forced convection. Temperatures should remain slightly cooler than normal through the first half of the week, then closer to normal for the back half. && .AVIATION...
