Near term

(Rest of tonight and Thursday) Issued at 1006 PM CDT Wed Oct 28 2026

High cirrus east of I-65 can be seen on satellite tracking east with clear skies filtering in over NW AL. This combined with light winds will allow for good radiational cooling tonight, bringing lows to the lower 40s to near 50 degrees. Given current dewpoints in the mid to upper 40s, we do think patchy dense fog will develop tonight but there is uncertainty regarding how widespread the fog will be. We do not plan to issue a dense fog advisory at this time, but will keep a close eye should conditions be met tonight.

High pressure will remain anchored across the southeastern US on Thursday, resulting in another day of warm and dry conditions. Highs will rise to the mid to upper 70s under mostly sunny skies. Moisture will gradually begin to increase across the area ahead of an approaching system, but models may be overdoing the strength of this advection this early in the forecast. Therefore, dewpoints may need to be adjusted downward in future forecast updates.

Short term

(Thursday night through Saturday) Issued at 1006 PM CDT Wed Oct 28 2026

Similar to tonight, patchy dense fog will need to be monitored again tomorrow night into Friday morning but there are uncertainties regarding cloud cover. Moisture will continue to increase on Friday as the remnants of tropical storm Vance track northeast and embed into a broader troughing pattern. While this won't result in any rain, expect to see an increase in cloud cover throughout the day, especially during the afternoon. Highs will top out in the upper 70s/lower 80s with lows in the 50s.

Moisture still appears to be limited with this system and rainfall totals have trended downward significantly over the past few days. Most likely amounts now look to be less than 0.5" across most of the area with the highest amounts south of the TN River. With a limited thermodynamic environment along with stronger synoptic forcing well to our north, no severe weather is expected.

Long term

(Saturday night through Wednesday) Issued at 1006 PM CDT Wed Oct 28 2026

Light to moderate rain (and perhaps some embedded drizzle) will persist into Sunday as the shortwave trough drops southeast of the TN Valley. Temperatures will remain on the cool side as a result of the clouds and precipitation, with readings staying in the 60s. Dew points will remain in the lower to middle 50s. Temperatures will moderate into the lower to middle 70s Monday and Tuesday. A stronger upper low/trough will move into the Plains Tuesday and lower MO Valley through the western Gulf states on Wednesday. This will spread increasing upper level divergence and UVVs into the MS and TN Valleys. Low level southerly flow will increase substantially ahead of the system, allowing dew points in the 50s to advect northward. A slower progression of the trough and cold front may delay arrival in the TN Valley until Wednesday and it remains unclear if the trough will become more sheared out to the northeast and not dig deeper into the Gulf states and southeast. In either case, medium to high PoPs are warranted in the forecast by Wednesday. At this early stage, instability looks to be quite meager with low probability of SBCAPE of 200 J/kg or higher, so the threat of severe weather remains low, but we will continue to assess trends as we move forward.

Aviation

(18Z TAFS) Issued at 417 PM CDT Wed Oct 28 2026

VFR flight weather conditions are forecast. There is a low chance of patchy BR/FG from 08-13Z over and near bodies of water.
