.SHORT TERM...
(Tonight through Monday Night)
Issued at 1041 PM CDT Sat Aug 9 2025

Large area of high pressure remains over the area to end the
weekend, leading to what will be another relatively quiet day across
Middle TN. Light southerly flow will persist over the area,
resulting in some low-level moisture advection. With high pressure
overhead, rain chances for Sunday afternoon remain very low with
CAMs showing just very isolated activity. Most of the area will
stay dry as temperatures top out into the low and mid-90s for
areas west of the Plateau. Heat index values will be the mid to
upper-90s for this area as well.

By Monday, rain chances will be on the rise as high pressure shifts
to the southeast in response to an upper-level trough moving across
the Plains. Southerly flow strengthens in response to this pattern
shift, advecting more low-level moisture into the area. Monday`s
rain chances increase to the 20-30% range with best chances being in
the afternoon and evening with these dirunally-driven storms. Higher
humidity will also mean that heat indices will be on the rise as
well, with many locations across the western half of Middle TN
getting close to triple digit heat indices.

.LONG TERM...
(Tuesday through next Sunday)
Issued at 1041 PM CDT Sat Aug 9 2025

Rain chances will steadily increase through mid-week as an overall
troughing pattern continues before peaking on Wednesday to about 40-
70% as a trough tracks east through the Ohio River Valley.
Steadily increasing moisture values will also keep heat indices
high in the mid-90s to the low-100s at times. High pressure tries
to build back over the southeast US Thursday and beyond, but daily
low to medium rain chances will continue even into next weekend.
Unfortunately, the heat will stick around, too, with highs each
day in the 90s and heat indices continuing to rise into the
low-100s at times.

VFR conditions are expected at all sites through the period,
except for brief late night fog at SRB and perhaps CSV. Otherwise
skies will feature scattered cumulus clouds. Winds will be light,
mainly from the southeast. Very isolated showers will form Sunday
afternoon, but prob for impacts at terminals is much too low to
include in tafs.
