264 FXUS64 KHUN 160158 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 858 PM CDT Sun Sep 15 2024 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 858 PM CDT Sun Sep 15 2024 Stray showers continue to push northwestward through the TN Valley tonight, producing light precipitation through the I-65 corridor and into portions of NW AL. A low chance of showers (20% or less) continues overnight into the early morning hours for portions of Cullman, Morgan, Lawrence, Franklin (AL), Colbert, and Lauderdale counties. However, most locations are forecast to remain dry overnight into Monday. Low temperatures are forecast to drop into the low to mid 60s accompanied by winds around 5-10 mph with occasionally higher gusts. Despite clearing skies in northeast AL and portions of southern middle TN, winds should mitigate fog formation overnight. However, confidence in this is low and the forecast may need to be adjusted if winds decrease. No major changes were made to the previous forecast as it remains on track. && .SHORT TERM... (Monday through Wednesday) Issued at 123 PM CDT Sun Sep 15 2024 To start off the work week, the Tennessee Valley will be located in between the remnant convergence boundary to our west and a tropical like wave off the Carolina coast. As a result, subsidence in between these two features will allow for mostly sunny skies and dry conditions. Temperatures will be near climatological norms for this time of year with afternoon highs in the mid 80s and overnight lows in the upper 50s to lower 60s. A welcomed changed after the last several cloudy and rainy days. && .LONG TERM... (Wednesday night through Saturday) Issued at 223 AM CDT Sun Sep 15 2024 Sandwiched between weak troughing on either side at the mid levels, high pressure to our NE will remain the dominant feature through the long term forecast. This will continue our string of mundane weather with virtually no rain chances and clear skies each day supported by the high and dry airmass. With a mostly unchanged airmass in place through the duration of the long term, highs will remain in the mid to high 80s each day with lows gradually increasing from the low 60s to the high 60s by the end of the period. && .AVIATION... (00Z TAFS) Issued at 617 PM CDT Sun Sep 15 2024 Predominately VFR CIGS are expected at both terminals through the period. There is a low chance (~30%) that a light shower could impact either terminal, but only included VCSH at terminals (KHSV until 1Z and KMSL until 4Z. Winds will likely stay up a bit early this evening around 10 knots gusting to 15 knots. Leaving fog or any VSBY reductions due to fog out for now at both terminals, with low confidence concerning how much clearing we will see tonight into early Monday morning and expected winds. && .HUN WATCHES/WARNINGS/ADVISORIES...
