.NEAR TERM...
(Today)
Issued at 156 AM CDT Wed Jul 29 2026

A highly anticipated cold front is currently makings its way
across the TN Valley. Along and ahead of the front, light showers
and a few thunderstorms are slowly propagating SE. Through the
night as the front progresses, low rain and storm chances will
remain in the forecast with best chances south of the TN River.

As the sun rises, the front should be shifting to our south
leaving some residual showers and cloud cover mainly in NW AL.
With the front to our south, NW surface flow will work to usher in
slightly cooler and much drier air. Temps will be limit to the
high 80s to low 90s with dew points potentially dropping into the
60s by the end of the day! The drier air will infiltrate the whole
profile and looks to reduce both rain chances to less than 10% by
this evening and drop PWATS below 1.5 inches.

.SHORT TERM...
(Wednesday through Friday)
Issued at 1018 PM CDT Tue Jul 28 2026

The setup for the short term will leave the Tennessee Valley under
prevailing north northwesterly flow as the region remains in
between a trough to the east centered over NY on Wednesday and
ridge to the west across NM and the Southern Plains. Behind the
cold front, drier air will begin to filter in on Wednesday as the
front stalls to our south and by Thursday morning PWATs are
forecast to be below 1.0" across the area. Forecast max temps and
heat indices will also fall and highs will drop closer to normal
in the mid-80s to low 90s through Friday. Low temps will also see
a reprieve by Friday morning in the mid-60s which will be a very
welcome change. Outside of some lingering shower activity along
the frontal boundary Wednesday morning, the short term period will
remain dry until Friday night when we will begin to see a weather
pattern change for the long term period.

.LONG TERM...
(Saturday through Tuesday)
Issued at 1018 PM CDT Tue Jul 28 2026

This weekend will begin a more unsettled weather pattern as a
trough digs southward across the Great Lakes region on Saturday
and Sunday. Ensembles differ in the handling of this trough with
the EPS showing a stronger trough closing off to our north and the
GEFS remaining an open wave over the Ohio River Valley into early
next week. Regardless, rain and storm chances will increase this
weekend into early next week as moisture filters back into the
area. Temps should remain at or below normal during the day with
milder overnight lows. We will have to wait and see for the finer
details of any severe threat that may evolve as models become
more in sync in the coming days. Make sure to check back if
planning anything outside this weekend as the forecast can and
will likely change.
