The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Huntsville, AL wrote its last area forecast discussion before the first event at Nov 18, 11:10 PM CST, 50 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 1110 PM CST Mon Nov 18 2024 ...New AVIATION... .NEAR TERM... (Tonight) Issued at 904 PM CST Mon Nov 18 2024 An upper trough axis has taken on a negative tilt as it shifts northeast into the Midwest/Upper MS River Valley region. With this comes an increase in divergent flow aloft while lower level pressure gradients tighten. We will continue to see an increase in S/SE winds overnight with sustained winds up to 15mph and gusts up to 30mph at times. A cold front currently stretching from central IA south through eastern AR will continue to track east overnight and will fuel heavy rain and thunderstorms across the Southeast. Have increased rain chances a little earlier over NW AL given current radar trends, with a few light showers seen over NE MS. Expect showers and embedded storms to make their way into NW AL closer to the 1-2AM timeframe and spread east through the early morning hours. Model soundings continue to indicate that any elevated instability will be limited at best, and therefore no severe weather is expected overnight. With that said, it would be a good idea to secure any loose outdoor items that could be easily blown away. Heavier and more widespread rain will arrive closer to sunrise, so be sure to grab a rain jacket before headed outdoors tomorrow. Overnight lows will be a good 10-15 degrees above seasonal norms, only falling into the mid 50s/60s. && .SHORT TERM... (Tuesday through Thursday) Issued at 302 PM CST Mon Nov 18 2024 This strong forcing continues to be seen Tuesday morning and pushes east more quickly this run of model suites. In latest guidance that stronger forcing pushes southeast of the area between noon and 2 PM. Not sure we will be able to see surface based instability develop before this happens, despite the strong low level flow ahead of the pre-frontal trough axis. Another limitation to the severe weather will be drier air being advected into the atmospheric profile around and above 700 mb. Combined with the lack of lift, thinking lingering light to moderate rain may be the extent of what we see later in the afternoon in the early evening hours. That being said, definite and decent rainfall will result from this system, given the strong forcing seen in guidance from 850 mb to 700 mb in the morning and the fairly high PWAT values in place. Expect a good half an inch to an inch in most locations. Lingering light rain will continue to be a possibility Tuesday evening, as weak lift remains in place ahead of the actual cold front lagging behind the pre-frontal trough axis, mainly east of the I-65 corridor. Lower dewpoints will work into the area behind the pre-frontal trough axis. Some light winds may develop as well ahead of the actual front late Tuesday night. This could allow lows to drop a bit lower in western areas. Lows in the upper 40s (west) to mid 50s (east) look reasonable. The main cold front looks to push into northwestern AL Wednesday morning and move east across the area during the day. Morning cloud cover and the cold air advection will help to make for a noticeable cooldown (highs in the upper 50s to lower 60s). Went a tad above guidance since some sunshine will likely be seen in the afternoon. It will be breezy, but 850 mb and 700 mb winds do not look strong enough for more than 10 to 20 mph winds with some gusts to around 30 mph at this time. A stronger re-enforcing cold front moves southeast Wednesday night into Thursday. Overnight thermodynamic structure doesn't look conducive for Wind Advisory conditions at this time. However, as we move into the morning hours on Thursday, 850 mb winds between 40 and 50 knots are seen that could be mixed up to. This would likely allow for sustained winds of 20 to 30 mph with gusts between 35 and 45 mph if 850 mb winds are that strong. The really chilly air moves into the area behind this re-enforcing front on Thursday Highs will be hard pressed to climb above the lower to mid 50s. With strong cold air advection continuing Thursday night, guidance hints at low dropping into the lower 30s. However, gradient winds will likely keep frost or freezing conditions from occurring. && .LONG TERM... (Friday through Sunday) Issued at 302 PM CST Mon Nov 18 2024 The pressure gradient finally relaxes on Friday night into Saturday as high pressure builds over and south of the area. To our west, an upper level ridge deamplifies and becomes more zonal through the weekend. This will present the opportunity for it to be pretty chilly overnight with some freezing or frosty conditions to occur through the weekend. The coldest day will likely be Friday into Saturday morning (highs in the lower 50s/lows in the upper 20s to lower 30s) A gradual warming trend is expect by Sunday into early next week with highs climbing back into the 60s. && .AVIATION... (06Z TAFS) Issued at 1110 PM CST Mon Nov 18 2024 Ceilings will lower to MVFR levels early Thursday morning as SHRA push in to the region with an advancing cold front. This front will also bring gusty winds between 15-20 kts out of the SE/SSE. By the afternoon, SHRA will become more widespread and ceilings will lower to IFR levels (potentially falling below 1 kft) for much of the day. These lower ceilings will continue this evening as low stratus settle in even as precipitation begins to be lighter and winds drop to under 10 kts. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
