624 FXUS64 KHUN 191444 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 944 AM CDT Thu Sep 19 2024 ...New NEAR TERM... .NEAR TERM... (Rest of Today) Issued at 944 AM CDT Thu Sep 19 2024 The on-going forecast appears to be on track, as weak and broad surface high pressure situated across the eastern third of the CONUS controls the sensible weather. After a mild, and foggy start in a few spots, area temperatures have risen into the low/mid 70s. Under generally sunny skies, a warm late summer day remains in the forecast, with highs warming into the mid/upper 80s with light winds. No changes were needed at this time. && .SHORT TERM... (Tonight through Sunday) Issued at 215 AM CDT Thu Sep 19 2024 Through the short term forecast mid level ridging will build in from the SW maintaining high pressure as the dominating weather feature. This will support a gradual warming trend through the weekend with highs building from the low 90s on Friday to the low to mid 90s Saturday and Sunday. Continued subsidence from high pressure will promote mostly clear skies and calm winds making for a nice, if a little warm, weekend. && .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... (12Z TAFS) Issued at 541 AM CDT Thu Sep 19 2024 Trends are showing fog beginning to form along the TN River, have included a tempo group at MSL from 12-14Z for lower visibilities, yet left it out of HSV due to lower confidence. Fog should clear out after 14Z with VFR conditions prevailing for the duration of the TAF period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
