.DISCUSSION...
(This afternoon through Sunday)
Issued at 140 PM CDT MON SEP 14 2026

Persistent upper-level ridging will remain the weather story for
this forecast, as the apex of the ridge is currently establishing
itself over Tennessee. This ridge will very quickly "switch off"
rain chances for the week, with the highest probabilities in the
afternoon not even reaching 10% through Friday. Under this high
pressure, afternoon high temperatures will quickly stabilize in
the low to upper-90s, remaining here until next weekend as well.
While afternoon temperatures will be hot, dew point values will
be lower in this drier airmass. In turn, heat index values will
mostly range between 101-103, keeping us below any type of heat
critical thresholds.

By this weekend, it appears as if the upper-level pattern begins
to shift, as a low pressure works its way around the ridge. This
low will work into the Gulf via the Atlantic, continuing to work
west over the next few days. While confidence in the exact
placement and movement of the disturbance is low, anything that
does work into the Gulf should suppress the ridge and increase
rain chances through the weekend.

.FIRE WEATHER...

Minimum RH values are expected to stay between 35-45% through
next week, with very limited rain chances in the forecast. While
fire weather concerns remain low for now, increasing drought
conditions will push these concerns up by late next week if
significant rainfall does not fall by then.
