.SHORT TERM...
(Tonight through Friday Night)
Issued at 1125 PM CDT Wed Sep 17 2025
Through the week we have been sitting between a big ridge axis
over the Plains and Ms Valley and an upper trough along the east
coast. The ridge has given us warm temperatures while the trough
has provided a couple of weak disturbances with brief, localized
showers and storms. Low level northerly flow between these systems
has kept humidity levels tolerable, allowing temps to cool off
near normal levels at night.
The ridge will be our main wx system the next few days as it
gradually moves eastward and sets up overhead. Dry conditions are
expected Thursday and Friday with the warmest days of this warm
spell, including mid 90s some areas.
Overnight hours will continue to cool off nicely. Some patchy fog
will form, mainly Plateau and across our southern areas where
humidity levels are slightly higher.

.LONG TERM...
(Saturday through next Thursday)
Issued at 1125 PM CDT Wed Sep 17 2025
For this weekend, the NBM is painting a continued warm and dry
forecast under the ridge. But, some models are showing a little
weakening of the ridge with very small chances for isolated
showers Saturday PM and Sunday. Something to keep in mind as a
possibility, but nothing to be excited about.
Greater height falls will come Monday through Thursday as the
upper level pattern begins to change. This more "troughy" pattern
will ease high temps down into the 80s (still above normal). It
will also bring greater chances for scattered showers and a few
storms, but no widespread soaking rainfall.
