.NEAR TERM...
(Today)
Issued at 152 AM CDT Sat Sep 21 2024

Some very light fog is possible heading into the early morning hrs
this Sat, mainly in the more fog prone sheltered/valley areas and
near any larger bodies of water. Otherwise, high pressure at the
sfc remains layered across the southern Atlantic states, while a
weak upper ridge axis gradually drifts eastward over the southern
Plains/western Gulf region. These synoptic features are resulting
in another quiet/seasonably warm day for the mid TN Valley, as
afternoon highs again climb mainly into the lower 90s/near 90F,
under mostly sunny skies.

.SHORT TERM...
(Tonight through Tuesday)
Issued at 152 AM CDT Sat Sep 21 2024

Little change in the overall pattern is expected into the second
half of the weekend period, as high pressure over the southern
Atlantic region remains fairly stagnant, while the upper ridge
pattern translates more into the SE states. Lows early Sun look
to fall into the mid 60s/near 70F, before temps again rebound into
the lower 90s/near 90F later in the day. The upper ridge axis will
continue to drift eastward into the first half of the work week,
as a weak upper trough pattern traverses over the mid Plains. An
increase in cloud cover may keep afternoon highs Mon closer to the
90F mark, before a weak cold front out of the Plains states
approaches the Mid South/TN Valley areas on Tue. Low chances of
showers/tstms (20-30%) will develop along/ahead of the approaching
front on Tue, as highs trend more in the upper 80s/near 90F. Lows
into early Tue also look to remain in the mid 60s/near 70F.

.LONG TERM...
(Tuesday night through Friday)
Issued at 152 AM CDT Sat Sep 21 2024

The front will settle more into the region by the middle of next
week and potentially stall invof the mid TN Valley heading into
the end of the work week. The upper trough pattern will also
translate thru the Midwest/OH Valley regions past mid week,
maintaining a low chc of showers/tstms in the forecast thru the
end of the forecast period. The lack of a stronger return flow
pattern/associated influx of moisture will offset the prob for
higher rain chances next week, although this could easily change
pending future model runs. Slightly cooler air will at least
filter into the area Wed thru Fri with the passage of the front,
with afternoon highs trending more in the lower/mid 80s. This
slightly cooler air will also result in lows predom in the
lower/mid 60s thru the end of the work week.

maintained in the 09-12Z time frame. Light/var winds will also
become WSW near 5-7kt late Sat morning.
