.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).
