- Unsettled weather continues into next week, even after the cold front.

DISCUSSION

Issued at 226 AM EDT Wed Jun 10 2026

Today we will be transitioning from troughing and a persistent boundary to those features exiting, ridging building in, and thus PWs dropping. CAMs try to bring in precipitation to southwest VA as early as sunrise or after. PoPs for much of the area will be the lowest they've been in a couple of days. Far southern parts of the CWA may even skip precipitation today. Thus, best chance of accumulating precipitation will be for northeast TN into southwest VA today. Even though isolated flooding threat is still there, 00z HREF and RRFS do show PW values dropping the closer we get to the end of the day today, which makes sense given the ridging trying to build in.

With the ridge building in, showers and storms may be of the typical summer variety tomorrow with better chances over the terrain and a decrease in activity towards nightfall. Much of the forecast area outside of the mountains could very well remain dry.

Temperatures will rise a couple of degrees each day through Friday, with 70s dew points unfortunately sticking around. A cold front around the start of the weekend will bring a brief bout of relief from highs in the valley maxing near 90 and those nasty dew points. Dry weather doesn't appear will follow the front, with daily precipitation continuing into the end of the forecast period, according to models. Although, deep troughing next week suggests we may possibly get a break from the 90s temperatures after Friday; low 80s are being hinted at.

AVIATION

(06Z TAFS) Issued at 100 AM EDT Wed Jun 10 2026

Primarily VFR conditions are expected for the rest of the night with some lingering chances for reductions. Patchy fog development is possible, but fog has been left out of the TAFs for the time being. Throughout the day, southwesterly to westerly winds will increase, along with developing showers and storms by the afternoon. This will be most noticeable around TRI with VCTS added, in addition to a PROB30. TYS has some chances for impact, but only a PROB30 was added. CHA has relatively low chances for rain in general.
