KEY MESSAGES

Updated at 745 PM EDT Mon Oct 19 2026

- Dry weather dominates the forecast period, with cool mornings and pleasant afternoons each day. Afternoon relative humidity will remain on the lower side as well.

DISCUSSION

Issued at 235 PM EDT Mon Oct 19 2026

We will remain on the eastern periphery of an anomalous upper level ridge centered across the central CONUS through the period. A trough will also translate atop the northern Great Lakes and into the New England Region mid/late week to assist in moderating temps to only a few degrees above normal locally. The associated high pressure and subsidence aloft will also promote clear skies and drier air. These dry/clear conditions will allow for cool mornings but very pleasant afternoons. The favorable radiational cooling may also allow for some patchy valley fog, and perhaps isolated frost in sheltered valleys across far NE TN/SW VA and the higher terrain each morning as well. Overall, a very comfortable weather pattern lacking significant impacts for the foreseeable future.

AVIATION

(00Z TAFS) Issued at 745 PM EDT Mon Oct 19 2026

VFR conditions with light northerly winds are expected at all terminals through the period. Likely will have some patchy fog in the TN valley come tomorrow morning, but confidence in it impacting any particular terminal is very low, so a VFR forecast it is.
