953 FXUS64 KHUN 160400 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 1100 PM CDT Wed Oct 15 2025 ...New AVIATION... .KEY MESSAGES... Updated at 939 PM CDT Wed Oct 15 2025 - High chances for showers return Saturday night into Sunday with low chance of strong to severe storms. - Gusty winds 20-25 mph are expected Sunday afternoon. && .NEAR TERM... (Rest of tonight and Thursday) Issued at 939 PM CDT Wed Oct 15 2025 The upper level pattern has a large amplitude ridge over the Central CONUS with a trough across the Northeast. Underneath the ridge, high pressure centered over the western Mississippi River Valley continues to be the main influence in our local weather pattern across the Tennessee Valley. As a result, expect another tranquil evening with clear skies and light winds with overnight lows dropping down into the low to mid 50s. The development of fog is not anticipated given winds remaining around 5mph through the night. Not much change in the weather pattern as we head into Thursday with high pressure dominating the local weather conditions. Clear skies will warm temperatures in the afternoon up into the lower 80s, which is near to slightly above climatological normals for this time of year. && .SHORT TERM... (Thursday night through Saturday) Issued at 939 PM CDT Wed Oct 15 2025 We begin a gradual pattern shift as we move through the end of the workweek into the start of the weekend. As the upper level ridge pushes towards the East Coast, a short wave trough begins to dig down across the Upper Plains. Closer to home, southerly flow returns on Friday allowing for moisture advection off the Gulf to occur. Since there is a lot of dry air in place across the Tennessee Valley, dry weather continues through Saturday afternoon with highs Friday and Saturday rising into the low to mid 80s . However, it will feel a bit more humid with dewpoints rising into the lower 60s on Saturday. && .LONG TERM... (Saturday night through Wednesday) Issued at 939 PM CDT Wed Oct 15 2025 Our long stretch of dry weather comes to end Saturday night as a sfc low pressure system moves across the Midwest with a cold front draped to its south that is forecast to swing through the Tennessee Valley. Expect high chances for showers to begin late Saturday night into Sunday with the cold front passage. Chances for thunderstorms remain low and the probabilities for strong to severe storms appears very low at this time. If any strong storms do develop along the front, gusty winds will be the primary concern given good deep layer shear. However, forecast instability remains quite low limiting the likelihood of deep convection. Flooding threat appears low as well given the quick movement of the front and the antecedent dry conditions. As the front passes through the area, expect gradient winds to increase 20-25 mph on Sunday. These will be ushering in another Fall airmass with temperatures expected to drop Sunday night into the low to mid 40s. The Fall weather pattern continues through the middle of next week with afternoon highs topping out in the 70s Monday through Wednesday. Model guidance is suggesting another weak cold front passing through the area on Tuesday night/Wednesday which may bring a low chance for showers, but confidence remains low in precip given the lack of moisture return ahead of the front. && .AVIATION...
