548 FXUS64 KHUN 161800 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 100 PM CDT Mon Sep 16 2024 ...New NEAR TERM, SHORT TERM... .NEAR TERM... (Tonight) Issued at 100 PM CDT Mon Sep 16 2024 Dry air is finally working its way into the area this afternoon and is helping to dissipate cloud cover across the region, making for a pleasant rest of the day. Winds will decouple overnight and the combination of these very light winds and the clear sky will allow for good radiational cooling as temperatures fall back into the upper 50s to lower 60s. Additionally, moist boundary layer conditions from the recent rainfall may allow for some patchy fog development in sheltered river valleys and across the Bankhead National Forest. && .SHORT TERM... (Tuesday through Thursday) Issued at 100 PM CDT Mon Sep 16 2024 The Tennessee Valley will remain wedged between a building ridge to the west that will attempt to push into the area by midweek and the remnant potential tropical system meandering over the Carolinas. The end result will be a continued dry forecast, with a gradual warming trend taking shape by Wednesday/Thursday as highs climb back into the mid to upper 80s. Continued clear/calm conditions and saturated soils due to recent rainfall (especially in northwest Alabama), patchy fog will likely remain in the forecast each night during this timeframe. && .LONG TERM... (Thursday night through Sunday) Issued at 250 AM CDT Mon Sep 16 2024 The upper ridge will shift even farther east by Friday, and will result in temps nearing 90 degrees as we head into the weekend. At the sfc, high pressure will sink southeast through the Ohio Valley and will further enforce a dry forecast through Sunday. The next feature to watch will be an upper low that will shift west into SC and GA by the end of the weekend, and could result in an increase in clouds. Low level northeasterly flow will also result in slightly cooler temperatures on Sunday, topping out in the low to mid 80s. Overnight lows will range from the low to mid 60s each night. && .AVIATION... (18Z TAFS) Issued at 1139 AM CDT Mon Sep 16 2024 VFR conditions will be the predominant flight category at each terminal through the period, with gusty easterly winds ending by sunset. Clear/calm conditions overnight may lead to some light MVFR fog at both terminals between 08-12z. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
