KEY MESSAGES

Updated at 1007 AM CDT Thu Oct 29 2026

- Medium to high chances (60-80%) of showers and a few storms will return to the forecast late Saturday night into Sunday.

- Low to medium chances (30-50%) for showers and a few storms will return during the mid part of next week.

NEAR TERM

(Tonight) Issued at 256 PM CDT Thu Oct 29 2026

No major changes to the previous forecast besides lowering dew points slightly both the rest of the afternoon as well as tomorrow due to trends.

Previous Discussion: Dry weather continues today and tonight over the Tennessee Valley as an upper level ridge centered over the Gulf brings high pressure to the area. Highs today are forecast to warm into the mid to upper 70s under mostly clear skies with light, variable winds. Tonight, temperatures drop to around the mid 40s to low 50s. The risk of fog formation remains very low- especially over NW AL where cloud cover will gradually increase overnight.

SHORT TERM

(Friday through Saturday night) Issued at 1007 AM CDT Thu Oct 29 2026

Friday, the forecast persists with sfc high pressure continuing to allow dry conditions throughout the TN Valley. Highs will climb slightly higher than today, with temperatures reaching the upper 70s to lower 80s. Friday night, lows will be mild- dropping into the mid to upper 50s in most locations.

For those spending time outdoors trick-or-treating or otherwise on Saturday/Halloween, we continue to bring the good news that rain has been pushed later. Most of the heavier rainfall will not arrive until late Saturday night into Sunday. While we cannot rule out a sprinkle or very light shower, we can say it will likely be an overall pleasant but muggy evening as temperatures reside in the 60s to lower 70s during the core evening hours (4PM-8PM). These temperatures should remain mild overnight, with lows dropping into the 50s by early Sunday morning.

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.

(18Z TAFS) Issued at 1206 PM CDT Thu Oct 29 2026
