.NEAR TERM... (Tonight) Issued at 843 PM CDT Thu Sep 25 2025
Storms that moved in from NE Mississippi have dwindled down the past couple of hours, however, showers still exist along the I-65 corridor. These showers have a very low chance of producing lightning and are expected to continue weakening as they push into NE Alabama- possibly dissipating completely within the next 1-2 hours. While there are low chances (10% or less) for a few lingering showers overnight, the area should remain mostly dry through tomorrow afternoon. As skies clear overnight, there is a low chance of patchy fog development, especially in areas that received rainfall today as well as along large bodies of water.

.SHORT TERM... (Saturday through Monday) Issued at 843 PM CDT Thu Sep 25 2025
As the sfc low pressure system and subsequent cold front continue to move southeastward over portions of the Tennessee Valley, low to medium rainfall chances (20-40%) continue. These will primarily be along I-65 and eastward as the cold front stalls to our southeast through the first half of the weekend. A stronger storm cannot be ruled out Friday afternoon as instability remains sufficient (1200+ J/kg) along with decent low level lapse rates (7-7.5 C/km). Shear continues to be inadequate, eliminating the risk for any organized severe weather to occur.
Dry weather will return to the Tennessee Valley Sunday and continue through early next week. Highs during this time are forecast to be in the upper 70s to mid 80s with overnight lows dropping into the upper 50s to lower 60s.

.LONG TERM... (Monday night through Friday) Issued at 843 PM CDT Thu Sep 25 2025
A dry forecast continues through the first half of the work week as an upper level ridge and subsequent sfc high pressure filters into the Tennessee Valley from the west. Low rain chances creep back into NE Alabama by mid week as the aforementioned cold front shifts back to the NE and stalls over the Carolinas. However, confidence in this is low as we continue to watch how the tropics unfold off the eastern coast. Therefore, maintained a mostly dry forecast through the end of the long term period. Highs during this time are forecast to reach the 80s with overnight lows in 60s.

.AVIATION... (00Z TAFS) Issued at 605 PM CDT Thu Sep 25 2025
A broken line of showers with a few embedded storms continues to progress over NW AL at issuance. This may bring slight reductions in VIS to the MSL terminal, but this line should move east of this TAF site by 1Z. Thinking that showers/storms will gradually decrease by the time it gets to north-central AL (HSV TAF site). With sunset, most activity should dwindle, with little to no rain forecast overnight. The main concern later tonight will be the potential for lower CIGs and possible patchy fog. Trends continue to show higher probabilities of this along and east of I-65. Not confident that CIGs at the HSV site will plummet below MVFR, but we`ll continue to monitor this. Did include at least MVFR CIGs as well as a slight reduction in VIS for the potential for patchy fog. Not anticipating widespread dense fog at this time. CIGs and any fog will then gradually clear through the morning hours on Friday, with low chances (10-30%) of showers and a few storms once again Friday afternoon (mainly along and east of I-65).
