Issued at 258 PM EDT Fri Oct 2 2026

A few showers have formed on radar this afternoon, currently across 
far eastern portions of the Cumberland Plateau. A rumble of thunder 
is possible in this activity as it moves eastwards. Tonight, 
showers, with maybe a rumble of thunder, will progress from the west 
to the east, and bring light rainfall to mainly a southwestern to 
northeastern portion of the area. It's conceivable that those 
closest to, or in, North Carolina will remain dry. 

Tomorrow, likely towards noon or early afternoon, we will see a 
transition occur between the morning showers across the north 
dissipating, and scattered showers and storms developing across 
Georgia and North Carolina. The mountains of far East TN and 
southwest NC have the best chances to see rainfall from the 
afternoon and early evening activity. Finally, Sunday is likely to 
see steadier rainfall for much of the day, especially across far 
eastern and southeastern counties bordering NC, as upper jet support 
helps fuel stratiform rain. Total rain amounts are reasonable at
1-2 inches, and I think flood risk remains very low overall. 
Guidance has been less enthusiastic about the potential for 
heavier rain rates on Sunday, but if the better forcing arrives, 
then we would see more moderate rain rates for a sustained period.
The best chances of exceeding 2" through this weekend exist along
the northern Cumberland Plateau (for rain now and tomorrow 
morning primarily), and across our most southern to eastern 
counties such as Marion, Hamilton to Clay and up to Unicoi (for 
rain tomorrow afternoon and on Sunday primarily). 

As we enter next week we will enter a rather benign weather 
pattern, with a strong polar jet north near the Canadian border 
and a weaker subtropical jet across the southern US. End result, 
shy of any cold air dam developments, will be temperatures 
hovering in the upper 70s each day next week for highs, 40s/50s 
for lows, and dry weather. Also known as fall!

(18Z TAFS)
Issued at 144 PM EDT Fri Oct 2 2026

A slow moving frontal band will be the main feature through the
weekend. Tonight clouds will become a greater fixture, with rain
being at least near the TAFs overnight. Exact placement of
stalling and then dissipating band of rain will determine rainfall
and impacts, if any, through morning. MVFR ceilings are likely 
tomorrow morning, before lifting or scattering towards the end of 
the period.
