018 FXUS64 KHUN 191041 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 541 AM CDT Thu Sep 19 2024 ...New AVIATION... .NEAR TERM... (Today) Issued at 215 AM CDT Thu Sep 19 2024 Fog, once again, will be the main focus of the near term forecast. Satellite observations show slightly moister air in place with mostly clear skies. With winds calming over the next several hours, fog is very likely as dew point depressions are already in the 0-2 degree range. While patchy fog will be possible everywhere, best chances of locally dense fog will be along and west of I-65, especially along the TN River. Any fog that does form will dissipate a few hours after sunrise. The remainder of the day will be rinse and repeat from the previous days as high pressure remains the dominating feature. Highs will be a few degrees warmer than yesterday in the mid to high 80s. Subsidence will greatly suppress any other impact with with skies mostly clear and very light wind through the remainder of the day. && .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. TN...None. && $$ NEAR TERM...RAD SHORT TERM....RAD LONG TERM....RAD AVIATION...RAD
