.NEAR TERM... (Today) Issued at 323 AM CDT Fri Oct 10 2025
A weak upper low was situated over the central AL/GA border. This disturbance was helping to produce scattered to broken clouds from middle Tennessee to the MS/AL border. A few showers that formed yesterday over the north/central AL/GA border have dissipated. Newer activity has formed over portion of central Alabama in the overnight, drifting west to southwest. Cannot totally rule out a shower or two could form over northern Alabama into the early morning; however chances are too low to include rain in the forecast at this time.
During the course of today, the above mentioned upper low should slowly move E-SE. As it reaches the Georgia coast, it will become involved with the development of an east coast nor`easter type system. Any showers from it should remain well east of this area.
An area of surface high pressure over New England was otherwise bringing cooler air southward across the greater Tennessee Valley. 3 AM temperatures ranged from the mid 50s to lower 60s with mainly light winds. This high should move offshore today, resulting in an easterly flow. Under partly cloudy skies, another seasonably warm day is expected, with high temperatures rising into the mid 70s (trending a bit warmer west, a bit cooler east).

.SHORT TERM... (Tonight through Sunday Night) Issued at 948 PM CDT Thu Oct 9 2025
As we head through through the weekend there will not be much change in the overall weather pattern across the Tennessee Valley. The upper level trough digs further south across the Southeast allowing northerly flow to keep the cooler and drier airmass in place. Overall, a beautiful fall weather weekend is in store with afternoon highs Saturday and Sunday in the mid to upper 70s with overnight lows in the upper 40s to lower 50s. There will once again be low chances of fog development each morning given the light winds and clear skies.

.LONG TERM... (Monday through Thursday) Issued at 948 PM CDT Thu Oct 9 2025
Heading into next week, the upper level ridge to our west amplifies and shifts eastward kicking the trough off the East Coast. High pressure over the western Gulf Coast will keep the persistent dry weather going for the Tennessee Valley through the end of the long term period on Thursday. With a more westerly flow pattern aloft, a gradual warmup is forecast with afternoon highs returning to the lower 80s Monday through Thursday. Overnight lows will also warm back up towards the mid to upper 50s by the middle of next week.

.AVIATION... (06Z TAFS) Issued at 1247 AM CDT Fri Oct 10 2025
Satellite data and regional sfc observations indicate that a layer of stratocu will persist across the TN Valley overnight, providing a sct-bkn coverage of VFR clouds in the 4-8 kft layer. Although the presence of clouds and minor advection of dry air into the region (with light easterly winds) will inhibit fog development at the terminals, patchy BR/FG may still occur in the deeper river valleys to the east of HSV. The stratocu layer is expected to dissipate around 12Z, with mostly clear skies and lgt/vrbl flow anticipated for the remainder of the TAF period.
