Not much change to the local weather pattern as high pressure
along the East Coast remains the major force in the sensible
weather. Expect similar conditions today as we saw yesterday with
afternoon highs rising into the low to mid 80s under mostly sunny
skies. Dewpoints are a few degrees higher today, but only in mid
to upper 50s making for another beautiful day to spend outdoors.

(Wednesday through Friday)
Issued at 852 PM CDT Mon Sep 8 2025
Despite slight changes in the overall pattern, the surface
conditions will remain largely unchanged through the short term
forecast. Through the short term, several upper level shortwaves
will ripple down from the Great Lakes through the TN Valley along
the base of the larger long wave trough situated across the
eastern CONUS. Aloft, this will only work to reinforce our dry
airmass with NW flow being maintained. At the surface high
pressure from the NE will continue its hold on us. High pressure
seeping south will largely suppress moisture to the coastal areas
keeping our dew points comfortably in the 50s and low 60s.
Subsidence from surface high pressure will work to keep skies
clear however under clear skies temps will embark upon a steady
warming trend. Temps will warm from the 80s on Wednesday to low to
mid 90s by Friday. The lower dew points will keep heat indices
below any heat products however conditions will feel noticeable
hotter than the start of the work week.

.LONG TERM...
(Friday night through Tuesday)
Issued at 852 PM CDT Mon Sep 8 2025
From Friday through Sunday, mid level troughing will exit off the
NE coast allowing mid level high pressure to push east into the
TN Valley. By Monday high pressure will be aligned at the surface
and aloft. Locally this will bring more of the same. Subsidence
will promote clear skies, surface high pressure will keep high dew
points refined to the coast, and our warming trend will continue.
Temps will be in the low 90s at the start of the period warming
to the mid 90s by the start of the work week. Fortunately NE
surface flow will keep our dew points comfortably in the high 50s
to low 60s limiting our humidity despite the heat.
