FXUS64 KHUN 240350 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 1050 PM CDT Thu Oct 23 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1014 PM CDT Thu Oct 23 2025 - Medium to high chances for rain and a few thunderstorms return Sunday through Monday. - Low to medium chances for rain linger through mid-week. - Cooler temperatures arrive late next week. && .NEAR TERM... (Rest of tonight and Friday) Issued at 1014 PM CDT Thu Oct 23 2025 Clear and cool conditions are forecast once again tonight as sfc high pressure remains dominant over the local forecast area. With clear skies and light winds, there is a low chance patchy frost could form in higher terrain areas in southern middle TN tonight but confidence in this is not high enough to include in the official forecast with this update. The sfc high will slowly meander towards the east as we get closer to the weekend but temps and moisture will remain on the lower side through Friday. We may see a few passing clouds through the afternoon, but otherwise sunny and mild conditions are forecast to close out the work week with light east/northeasterly winds. Highs will top out in the upper 60s/lower 70s with dry dewpoints in the 30s to lower 40s. && .SHORT TERM... (Friday night through Sunday night) Issued at 1014 PM CDT Thu Oct 23 2025 Broadening upper ridging will begin to move in as we head toward the weekend and will result in warming temperatures and a gradual increase in moisture. We will maintain a dry forecast through Saturday but will see an increase in clouds especially toward the late afternoon and evening hours. Highs will top out in the low to mid 70s with winds veering to the southeast. An upper low will shift across the central Plains and into the mid MS River Valley on Sunday and will bring increasing chances for rain and a few thunderstorms on Sunday. The highest (50-70%) chances for rain will occur later in the day into the evening and overnight. Model soundings show decent shear aloft at this time but cooler low level temps will lead to poor lapse rates and will work to hinder instability. For that reason, severe storms are not expected but winds could feel breezy at times through the day on Sunday with periods of heavy rainfall as well. Temps will top out in the low to mid 60s with lows in the 50s Sunday night. && .LONG TERM... (Monday through Thursday) Issued at 1014 PM CDT Thu Oct 23 2025 Long term guidance tends to diverge pretty significantly as we get into next week regarding the evolution of an upper low/troughing over the eastern US. This will ultimately lead to cooler temperatures toward the end of the week, but rain chances remain a bit more uncertain due to disagreements on where the better forcing/moisture will line up. For now, we will keep low to medium rain and thunder chances in through Thursday, with the best chances Tuesday into Wednesday. The good news is that there is no strong signal for severe weather or flooding at this time. Highs will generally reach the 60s each afternoon with lows cooling throughout the week, beginning in the 50s but cooling to the 40s toward the later half of the week. It is still pretty early, but signs are pointing to cooler temperatures as we approach Halloween, so be on the lookout for future forecast updates when planning for outdoor activities. && .AVIATION...
