.NEAR TERM...
(Tonight)
Issued at 210 PM CDT Wed Jun 11 2025

A midlevel cloud deck has developed over the Tennessee Valley
this afternoon. Expecting partly cloudy skies to persist
overnight, with calm to light variable winds area-wide. A low
chance of patchy fog is possible once again later tonight into
early tomorrow morning as well, especially for the river valleys
and near bodies of water. Lastly, lows are still on track to dip
into the lower to upper 60s later tonight. Overall, no significant
changes were needed to the forecast.

Previous Discussion:

This morning`s visible imagery depicts a few mid and high clouds,
but overall a mostly sunny sky. Surface high pressure will remain
in place over the central Appalachians today. Weak and variable
5h flow will persist as well. An 8h/surface boundary will lift
slowly northward into central AL, but this will keep cumulus and
any low chance of showers or thunderstorms well south of us today.
High temperatures will once again reach the middle to upper 80s
this afternoon.

.SHORT TERM...
(Thursday through Saturday)
Issued at 950 AM CDT Wed Jun 11 2025

An upper trough in the south central U.S. will sluggishly lift
north-northeast through Friday into Saturday, remaining west of
the MS River valley. The trough will induce a south-southwest flow
in low to mid levels, amplifying moisture and instability levels
across the TN valley and southeast U.S. A plume of 1.5+ inch PWs
will overspread the region quickly late this week. On Thursday,
thunderstorm chances will remain quite low, but then subsequently
increase greatly Saturday into Sunday with the help of small scale
MCVs that generate the next day or south nearer the Gulf Coast.
Also, the aformentioned surface boundary will lift northeast.
Overall, this will be a more summerlike pattern with mainly
diurnally driven thunderstorms which should tend to wane after
loss of heating. Lightning, locally heavy rainfall and brief gusty
winds will be the main hazards during this period. Dew points
will rise into the upper 60s to lower 70s. A near persistence
temperature forecast is foreseen with highs in the middle to upper
80s (lower 80s atop the higher plateaus), and lows in the upper
60s to lower 70s.

.LONG TERM...
(Friday night through Tuesday)
Issued at 1035 PM CDT Tue Jun 10 2025

The upper low will begin to broaden out and weak troughing will
pivot across the area late Saturday into Sunday, but there are
some disagreements regarding the northern extent of the warm
sector and the evolution of the upper low/trough at this range.
What that means in terms of the forecast each day will probably
result in very little change, as temps are expected to remain in
the mid 80s to low 90s each afternoon with lows in the lower 70s.
It will certainly feel more like summer as heat indices could
approach the upper 90s in some areas from Friday onward. High
rain/storm chances are forecast each afternoon especially during
peak heating hours. The western Atlantic high is forecast to
remain the main influence on weather here locally through Monday
but models begin to diverge beyond that time period. Stay tuned as
there are some signs that even warmer temperatures could be on
the way next week!

.AVIATION...
(00Z TAFS)
Issued at 652 PM CDT Wed Jun 11 2025

VFR conditions will persist through much of the TAF period at both
terminals aside from low chances for showers and thunderstorms
tomorrow afternoon. This threat has been handled by PROB30 groups
during key hours of the afternoon where MVFR conditions will be
possible within thunderstorm activity. Otherwise, expect mostly
clear skies and light winds.
