.NEAR TERM... (Tonight) Issued at 651 PM CDT Tue Oct 7 2025
The temperature forecast remains on track as u70s overspread much of northern AL and southern middle TN. Multiple surface convergence boundaries ahead of the main cold front continue to sprout scattered light to moderate rain across western portions of the forecast region, and are expected to continue advancing eastward throughout the afternoon. During the late afternoon into overnight period an abundance of cloud cover should continue as the main cold front advances through the area, bringing moderate chances of precipitation (PoPs 50%-60%) for most of the forecast area. Persisting cloud cover will allow low temperatures to remain mild in the m60s-u60s as precipitation ends early tomorrow morning.

.SHORT TERM... (Wednesday through Thursday Night) Issued at 651 PM CDT Tue Oct 7 2025
A cooler and drier airmass begins to advect in from the northwest in the wake of a passing cold front. As a result, the short term forecast period will feel like Fall with afternoon highs Wed in the mid to upper 70s and Thu in the low to mid 70s. Overnight lows will feel refreshing in the low to mid 50s. Biggest weather concern during this period is an increase in gradient winds in between the high across the Midwest and the trough across the East Coast. Winds Wed afternoon are forecast to gust 20-25 mph before diminishing in the evening. Otherwise, enjoy the Fall weather.

.LONG TERM... (Friday through Monday) Issued at 651 PM CDT Tue Oct 7 2025
Data from the latest suite of global models continues to suggest that a mid-level trough (initially across GA/SC) will evolve into a rather deep closed low as it drifts northeastward in the general vicinity of the southeastern Atlantic Coast over the course of the long term period. Although this development will occur in response to an intense high-level speed max digging south- southeastward through our region this weekend, it still appears as if our forecast area will remain on the dry/western side of the low, with little to no opportunity for additional rainfall (aside from a few afternoon showers along the Cumberland Plateau on Friday). Highs will slowly warm from the l-m 70s on Friday into the u70s-l80s by Monday, with pleasantly cool overnight lows in the u40s-l50s.

.AVIATION... (00Z TAFS) Issued at 703 PM CDT Tue Oct 7 2025
A broken band of showers and thunderstorms will continue to progress southeastward and away from the terminals early this evening, in conjunction with an initial prefrontal sfc trough. Although redevelopment of a few additional lgt SHRA could occur as a second (and more pronounced) sfc trough tracks southeastward later this evening and into the early morning hours Wed, this activity would likely be concentrated to the S/E of HSV, and we will not mention any precip in the TAFs attm. As residual mid- level clouds scatter, conditions may become favorable for the development of BR/FG early tomorrow morning given coverage of wetting rainfall today, high boundary layer RH and lgt/vrbl to lgt northerly winds. North-northeasterly gradient winds will strengthen btwn 12-15Z, with a broken layer of low-VFR stratus expected to persist for the remainder of the period.
