DISCUSSION

Issued at 140 PM EDT Sun Oct 11 2026

The circulation of what's left of Isaias is centered over southern WV and will continue lifting to the northeast. Southerly moving showers this morning will become more northwesterly as moisture wraps around the back side of the low. Precipitation chances will linger into early tomorrow for areas that are typically prone to upslope northwesterly flow. Only light accumulation amounts expected.

Mostly cloudy skies are evident on visible satellite imagery this afternoon. The edge of the cloud shield lays near Huntsville, along a line from NNW to SSE. Expect clearing from about SW to NE as we head into the night and tomorrow morning. Winds may be up just enough to keep fog from forming overnight. Southwesterly wind gusts up the valley today will translate and confine to the northeast and higher terrain into tomorrow as surface high pressure lifts up from the gulf, keeping the tighter pressure gradient.

For the coming week ahead, surface high pressure will take hold over the southeast underneath a strengthening upper ridge. 500 mb heights could reach 593 dam or so by the middle of the week. What this means for us is dry weather through approximately Thursday with temperatures increasing each day. Chattanooga, for example, may see temperatures real close to 90 Wednesday and Thursday, when normally they average 75 for highs in mid October.

A closed low over the west that may eventually become part of a deepening trough over northern tier of the country, will be our next best chance of rain when a potentially strong cold front sweeps through next weekend. This will bring a marked cool down with highs dropping into the 60s next Saturday. Although just outside the forecast period, Sunday morning lows may bring the season's first freezing temperatures to northeastern parts of the forecast area (NE TN, SW VA).

AVIATION

MVFR will continue at TYS and TRI with some reduction to IFR at TRI expected. A few showers will linger for the next few hours, but otherwise westerly to northwesterly flow will gradually decrease through the night into the early morning. Patchy fog is possible, mainly around TRI. Then, lighter winds and decreasing cloud cover are expected through the day.
