.DISCUSSION...
Issued at 1252 PM CDT Mon Sep 8 2025
Surface high pressure dominates the entirety of the Ohio Valley
early this week. Its flow keeps warm advection at bay for
another day, before return flow and building upper heights
start to heat us up again. So in the short term, the sensible
weather features of note, other than the spectacular enjoyment
of one more day with dew points in the 40s, and highs generally
in the 70s, approaching 80 degrees, includes the continued dry
environ producing daily RH minimums in the 20s-30s percentile,
and the nightly fog patches that guidance hints at daily.
Synoptic pattern evolution with time, briefly aforementioned in
part, produces an almost Omega-like blocking pattern here by
week`s end. H5 heights crank toward 590 DM, while amplified long
wave troffing blasts the West and East coasts. This will lead
to a strong warmup heading into mid September, as we see H8
temps around 8C this morning out of the 12Z Nashville
sounding...with the models all indicating a marked rise to more
than twice that by this weekend. That will be pushing our highs
into the 90s by as early as Thursday, with mid 90s by the
weekend. Fortunately, dew points rebound thru the 50s, but
struggle to pass 60F, and with the large scale subsidence under
the mid MS Valley centered ridge, we`ll stay dry. That keeps
daily RH minimums a fire planning risk, esp with drought
conditions continuing unabated.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 100 PM CDT Mon Sep 8 2025
High pressure keeps predominantly tranquil flight forecast
conditions this package. The only exceptions are potential
restrictions due to nightly MIFG, which will be more miss than
hit and confined primarily to brief periods in prone locales.
Winds are generally light upon their gradual anti-cyclone
trajectory flow pattern veer from northeast to southeast with
time.
