.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.
