343 FXUS64 KHUN 302003 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 203 PM CST Tue Dec 30 2025 ...New NEAR TERM... .KEY MESSAGES... Updated at 145 PM CST Tue Dec 30 2025 - Cold today with afternoon high temperatures likely to remain only in the 30s and lows tonight in the low/mid 20s. - A warming trend will begin Wednesday and continue through early next week - Medium-high chances for showers and thunderstorms return on Friday/Saturday. && .NEAR TERM... (Tonight) Issued at 203 PM CST Tue Dec 30 2025 Despite the abundant sunshine, temperatures have only climbed to between 34 and 38 degrees in most locations. With NNW winds of 5 to 10 mph, wind chill values are still in the mid to upper 20s in many locations. So stay bundled up if outdoors. We will likely see them climb a few more degrees into the upper 30s (except in southern middle TN - where highs may remain in the mid 30s) with maybe a 40 degree high here or there. Dewpoints have been slow to drop, but we are starting to see some mixing down of dewpoints as temperatures reach the 35 to 38 degree range. We will likely see these drop more over the next 2 hours, possibly into the lower teens/single digits. This will likely drop RH values to between 25 and 30 percent in some areas. The clipper system forecast by models to affect the area later this evening with cloud cover is racing southeast and currently stretches from central Minnesota SSW into eastern Kansas. The further advancement of this front southeast today into the evening hours will bring some high cloud cover to the area this evening before pushing southeast of the area after midnight. Winds will likely drop off and decouple this evening. Given the dry air in place, do not think temperatures will be able to drop low enough for fog development, before winds increase just ahead of and behind this front late this evening. With evening clouds and calm winds early before picking up behind the front, thinking lows tonight will likely be just a tad below last night's, dropping into the 22 to 28 degree range in most locations. && .SHORT TERM... (Wednesday through Friday) Issued at 1056 AM CST Tue Dec 30 2025 With sunshine despite some brief on and off cloud cover, a general warming trend is expected starting Wednesday. The building upper level ridge over the Gulf coast states should help to warm things up with boundary layer westerly to weak southerly flow returning. Highs should finally warm back into the 45 to 51 degree range in most locations (47 to 51 degrees NW AL) by Wednesday with another quick shot of cloudy conditions moving across the area again late in the afternoon into the early evening hours, courtesy of a weak stalled frontal boundary. Lows should only drop into the upper 20s to lower 30s by Wednesday night. As the area of high pressure over the Gulf coast states builds further north, highs on Thursday under sunny skies should climb into the mid to upper 50s. A few lower 60s may be possible towards NW Alabama and Cullman county. Overall, a dry and seasonable to warm New Years Eve and New Years Day (Thursday) will be on tap for the Tennessee Valley, with an area of high pressure at the surface still the dominant weather feature, with zonal flow continuing aloft. && .LONG TERM... (Thursday night through Monday) Issued at 1131 AM CST Mon Dec 30 2025 Our next weather maker is set to move in on Friday as a shortwave digs into the Deep South and sfc low pressure tracks across portions of Alabama. Southwest winds boundary layer winds will keep temps on the warm side Thursday night into Friday as increasing low level moisture brings overcast skies to the area by Friday morning. Right now there is fairly decent agreement among models that the sfc low will track either over central AL or further south, keeping us outside of the risk for any severe weather but right along the axis of heavier rainfall where some locations may receive up to 1" (south of the Tennessee River). We will have to monitor trends with surface based instability to make sure it do not nose further northward Friday afternoon into the early evening hours, when better shear will still be in place. However, the fact that the shortwave is pushing southeast through NW flow upstream, not expecting this to occur. Also, localized flooding issues are not expected given the high flash flooding guidance values and the abnormally dry to moderate drought conditions over the area per the U.S. Drought Monitor. Enough elevated instability may be present to support a few thunderstorms Friday evening (again south of the Tennessee River) as the heaviest activity moves through but this should all come to an end by midnight on Friday night. Light to briefly moderate light rain could continue wrapping around the surface low through Saturday morning. After this, dry conditions are forecast beginning Sunday with warmer highs in the upper 50s/lower 60s and lows near 40 degrees as we head into the work week. && .AVIATION... (18Z TAFS) Issued at 1131 AM CST Tue Dec 30 2025 VFR conditions are expected through the TAF period. Winds will be lighter and this evening may become light and variable at the terminals. Winds should pick up though after 06Z to around 5 kts, behind a quickly moving an dry clipper system that may bring some high CIGS to the area towards and into the early evening hours. && .HUN WATCHES/WARNINGS/ADVISORIES...
