277 FXUS64 KHUN 191745 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 1245 PM CDT Thu Sep 19 2024 ...New AVIATION... .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... (18Z TAFS) Issued at 1245 PM CDT Thu Sep 19 2024 Surface high pressure over the region should continue producing light winds at the terminals. Generally clear skies tonight along with light winds could result in patchy fog forming in the predawn. Confidence for fog is lower at KHSV than at KMSL. Any fog that forms should dissipate shortly after sunrise Fri AM, with VFR weather expected for the rest of the TAF. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
