.SHORT TERM...
(Tonight through Tuesday Night)
Issued at 1150 PM CDT Sun May 24 2026

A surface boundary/trough is slowly moving across Middle Tennessee
currently which led to development of rain showers near here at
OHX that produced brief heavy rainfall and minor flooding. This
has been the theme for a few days now as anomalous moisture values
and low-medium instability have combined to support fairly
widespread soaking rains at times. Beneficial rainfall has
certainly come in handy for the drought and streamflows have
recovered nicely over portions of Middle Tennessee.

For tonight, most rain activity is expected to be at a minimum.
Clouds will linger and winds are looking to be near calm. With so
much moisture at the surface, patchy fog is possible into the
early morning hours. Locally dense fog cannot be ruled out, but
there`s no current sign of widespread dense fog at this time due
to cloud cover.

While a shortwave trough will depart to our northeast overnight,
an upper-level low is now beginning to meander to our southwest.
This disturbance will gradually move east into Monday morning and
southerly low-level flow will continue to advect tropical moisture
into Middle Tennessee. Scattered to numerous showers and a few
storms are expected once again Monday afternoon. Poor lapse rates
will limit instability and eff. bulk shear should remain <20 kts.
No severe weather is expected but brief heavy downpours are
possible which may cause minor flooding. Tuesday will almost be a
repeat of Monday with continued influence of the weakening upper-
level low in the region.

.LONG TERM...
(Wednesday through next Monday)
Issued at 1150 PM CDT Sun May 24 2026

Middle Tennessee will see continued rain chances mid to late week
as a tropical airmass remains situated in the region. Best chances
will be during the afternoon and evening when instability
increases diurnally. Medium-range guidance is hinting at a cold
front moving into the region early next week which would lead to
drier air and a decrease in rain/convective activity.

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Sun May 24 2026

Currently, only scattered activity is occurring across Middle
Tennessee, and the HRRR doesn`t suggest any sort of increase in
activity overnight. However, a surface boundary is in the
process of crossing the mid state, so look for ceilings to
rapidly deteriorate during the next few hours as the boundary
tracks eastward, as well as some light fog as dew point spreads
shrink to near zero. Ceilings and vsbys will be slow to recover
tomorrow, and we also expect to see showers re-develop during the
afternoon. Surface winds will remain light/calm thru the TAF
period.
