KEY MESSAGES

Updated at 1219 PM EST Tue Nov 10 2026

- Showers arrive Wednesday night ahead of a cold front.

- Much colder temperatures for the latter part of the week. Light snow accumulations over the higher elevations of East TN and SW VA are likely.

DISCUSSION

Issued at 1219 PM EST Tue Nov 10 2026

The recent dry and mild weather will be coming to an end as we move into the latter half of this week. We will have another day of highs in the 65-70 range with mostly sunny skies on Wednesday before a big change arrives. For tonight, there could be some fog development again, especially near lakes and rivers. Confidence is low on how extensive it will become away from the lakes and rivers. Increasing high clouds may have an impact.

A shortwave trough will move SE from the northern Plains and merge with a large closed low over Ontario Wednesday night. Showers with the associated surface cold front will begin to spread into the area around 00Z Thursday, and sweep through the area pretty quickly. The merger of the aforementioned troughs and surface low intensification over the Mid Atlantic will advect cold air deep into the Southeast on Thursday, setting up a NW flow pattern for our area that persists for a few days. Cold temperatures aloft will generate some instability for scattered to numerous showers Thursday through Friday, with enhanced periods of precip coming with embedded vort maxes rounding the closed upper low. The NW flow will enhance precip in the higher terrain of E TN and SW VA, and showers there will change over to snow showers on Thursday night. Light snow accumulations are possible, but impacts in populated areas should be minor with temperatures only borderline for accumulating snow. Some flurries in the northern TN Valley and lower elevations of SW VA cannot be ruled out, but with no accumulation expected. Precip chances come to an end on Saturday as temperatures aloft warm and moisture exits with the departing upper low off the New England coast.

Building high pressure across the TN-OH Valley region will bring dry conditions for early next week, with below normal temperatures.

AVIATION

(18Z TAFS) Issued at 1219 PM EST Tue Nov 10 2026

VFR conditions are forecast through the period. Cannot rule out fog at TRI tonight, but confidence is too low at this time to warrant a mention. Later TAF issuances may need to add fog if confidence is higher.
