.DISCUSSION...
(Tuesday through next Monday)
Issued at 1147 PM CDT MON SEP 14 2026

Persistent upper-level ridging remains the main story for this
forecast period, with the ridge centered over Tennessee. This
pattern will effectively suppress rain chances through Friday,
keeping afternoon PoPs under 10%. Under the influence of high
pressure, high temperatures will hold in the low-to-upper 90s
through the upcoming weekend. Although actual temperatures will
be hot, lower dew points within this drier airmass should keep
heat indices in the 101-104 range, remaining below advisory
thresholds.

By the weekend, the upper-level pattern is expected to shift as
an upper low tracks from the Atlantic into the Gulf around the
periphery of the ridge. While model guidance shows uncertainty
regarding the exact placement and intensity of this feature, any
moisture returning to the Gulf should weaken the ridge and bring
higher rain chances for the weekend.

High pressure is expected to continue through the next 24 hours.
This will lead to VFR conditions across all sites through the
period. Typical diurnal wind pattern is expected with light to
calm winds increasing to 7-8kts through the daytime hours.

AMD NOT SKED is appended at AUO due to missing observations.

.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.
