433 FXUS64 KHUN 200502 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 1202 AM CDT Fri Sep 20 2024 ...New AVIATION... .NEAR TERM... (Tonight) Issued at 839 PM CDT Thu Sep 19 2024 High pressure promoting mostly clear and calm conditions overnight across the Tennessee Valley. Once again, this is a good setup for radiational cooling as temperatures fall back into the low to mid 60s in most locations. Late tonight into early Friday morning, patchy fog may also develop -- especially in sheltered river valleys around sunrise. Only minor tweaks were made to the forecast based on the latest obs/trends as everything remains on track. && .SHORT TERM... (Friday through Sunday) Issued at 235 PM CDT Thu Sep 19 2024 Dry conditions, with a warming trend will continue as we go into the upcoming weekend. As the general atmosphere stagnates and upper level ridging builds in from the SW, daily high and low temperatures should likewise rise. High temperatures on Friday should warm to around 90 degrees, and into the lower 90s during Saturday and Sunday. Lows in the period should range in the mid/upper 60s. Heat index readings on Sat/Sun into the low/mid 90s are expected. && .LONG TERM... (Sunday night through Wednesday) Issued at 215 AM CDT Thu Sep 19 2024 A slightly more active pattern will begin next week and an low pressure system pushes east across the CONUS. The shift will be gradual as the low pressure and associated front drifts towards the area. Through the long term rain chances will slowly build each day from about 10%-30% by Wednesday in response to the approaching front. In turn this will result in slightly more cloud cover and a gradual decrease in temps from the low 90s on Monday to the mid 80s on Wednesday. Models have yet to converge on exact details of the frontal passage regarding higher rain chances, have maintained blended guidance for now with subsequent forecast packages likely having a better idea as this moves into the short term. && .AVIATION... (06Z TAFS) Issued at 1202 AM CDT Fri Sep 20 2024 Light fog may develop early this morning, promoting a brief period of MVFR to localized IFR conditions around daybreak. Thereafter, VFR conditions will return through the remainder of the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
