685 FXUS64 KHUN 171315 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 815 AM CDT Tue Sep 17 2024 ...New NEAR TERM... .NEAR TERM... (Rest of Today) Issued at 815 AM CDT Tue Sep 17 2024 Morning fog is quickly dissipating now that heating is well underway and mostly clear conditions are prevailing across most of the area. One thing we`ll have to watch for today is some blow- off mid/high cloud cover from an area of low pressure over the Carolinas. Some of this cloud cover will work it`s way into areas generally east of I-65 and create partly to perhaps mostly cloudy conditions. For this reason, have tweaked cloud cover up slightly in our eastern zones. Despite this, good heating this morning will likely still warm most locations back into the mid to upper 80s by the afternoon. The only exception may be far eastern areas which could be a couple degrees lower if the clouds settle in sooner. && .SHORT TERM... (Tonight through Friday) Issued at 157 AM CDT Tue Sep 17 2024 The overall pattern will remain mostly unchanged through the short term forecast. The tropical low will begin to push back towards the Atlantic and maintain our high pressure influence both aloft and at the surface. This will support clear and dry conditions each day. A gradually warming trend will take place through the remainder of the week with temps rising into the low 90s by Friday. The clear and calm conditions paired with the saturated grounds from recent rainfall will support a fog concern for the next several nights. Conditions will be monitored each night should a Dense Fog Advisory be warranted. && .LONG TERM... (Friday night through Monday) Issued at 157 AM CDT Tue Sep 17 2024 High pressure will remain the dominating feature through the long term forecast. Mid level ridging will build in from the SW and remain through the weekend. While the overall trend will be clear and dry conditions with temps in the high 80s to low 90s, we will be monitoring any impacts from an upper low tracking east across the CONUS. Being on the eastern periphery of high pressure will place us in a NW flow regime marking a favorable pattern for SE expansion of clouds and rain from the parent low. While the current forecast is dry, we will be monitoring how these two features interact (NW flow from high pressure and low pushing east) over the next several days for any forecast changes. && .AVIATION... (12Z TAFS) Issued at 550 AM CDT Tue Sep 17 2024 Light winds and mostly clear skies will support VFR conditions through the day today. Late tonight after 6Z winds will calm and visibility reductions from fog is likely. Subsequent issuances of the TAFs will refine timing and intensity of fog. && .HUN WATCHES/WARNINGS/ADVISORIES...
