.SHORT TERM...
(Tonight through Wednesday Night)
Issued at 1145 PM CDT Mon May 25 2026

An upper-level low remains situated near the ArkLaTex and an
embedded vort max is now in northern Alabama moving toward Middle
Tennessee. These features are important as they both place
favorable forcing for ascent in the region within a plume of
anomalous moisture that is stretched from the Gulf Coast into
Kentucky where a stationary front sits along the Ohio River.
Rounds of rain showers are expected tonight into the afternoon
hours on Tuesday as a result, and most activity is expected during
the early to mid morning hours as the vort max to our south moves
through the Mid State. Hi-res guidance indicates decreasing
convective coverage in the afternoon as the vort max moves into
Kentucky, but there will be an increase in instability to support
a few thunderstorms despite the lower PoP.

Scattered to numerous showers and a few thunderstorms are expected
again on Wednesday with a low pressure/residual upper-low now to
our north with plenty of moisture across Middle Tennessee.
Afternoon instability and weak deep-layer wind shear could
support a few stronger storms Wednesday afternoon.

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1145 PM CDT Mon May 25 2026

Favorable moisture and instability will stick around across Middle
Tennessee Thursday and Friday to support diurnal rain chances.
Highest coverage is currently expected across the southwest half
of the forecast area where guidance is favoring the position of a
residual surface boundary, though mesoscale boundaries could also
be in play. Drier air will be looming just off to our north on
Friday. Additional rain/storm chances are forecast this weekend,
but PoP is gradually lowering through this time as there`s
ensemble support for lower moisture/instability associated with a
surface high sitting to our north. This drier air mass may work
into Middle Tennessee Sunday into early next week when an upper-
trough moves into the Northeast southward into the mid
Appalachians.

(12Z TAFS)
Issued at 619 AM CDT Tue May 26 2026

Light to moderate showers are impacting BNA, MQY, and CKV this
morning, bringing MVFR to IFR cigs with them. Heavier showers
will result in temporary vis restrictions. The majority of this
afternoon looks mostly dry with an increasing southerly wind.
Occasional gusts up to 20 kts will be possible. VFR cigs look to
temporarily return during this time period, staying in place
through late tonight when MVFR to IFR cigs return for the
overnight hours.
