.DISCUSSION...
Issued at 1212 PM CDT Mon Aug 31 2026

Strong high pressure at the surface and aloft remains locked in
here this week, pumping up the heat and humidity in the process.
Our prolonged duration Heat Advisory running the course of the
week looks to survive with ease, with all sites reaching into
the triple digits daily. Pushing past 105 degrees will be more
hit and miss, and tops the whole week looks to be near but not
in excess of 110 degrees, at least by means of the current data.
Wednesday-Thursday play the hottest, with most sites settling
somewhere from 103-106 degrees, though there may be sporadic
local exceptions slightly higher or lower.

Longer-range modeling still brings a chance of pcpn in toward
the week`s end, namely Friday-Saturday; but the chance is small,
smaller than it was yesterday, and as such, if the trend
continues, it`s possible the headline gets lengthened into
Saturday. We won`t jump on that this early, but it bears
watching as the week goes on.
