Drier air will finally begin to filter into the area today as
upper troughing pushes east and high pressure/upper ridging over
the western Plains becomes better amplified. The clearing line of
the dense stratus deck can be seen slowly shifting south through
western TN and should reach the local area later this afternoon.
Northerly winds will be gusty at times this afternoon and combined
with the cloud cover will help keep highs limited to the mid to
upper 70s. Although the drier air may be lagging behind a bit, it
should feel noticeably cooler today. Overnight lows will fall into
the upper 40s to mid 50s, with some clouds increasing over NE AL
towards the morning hours as a weak embedded shortwave passes
over the area.

(Thursday through Friday night)

The aforementioned ridge will continue to build to our west
through the end of the work week and large scale subsidence will
help keep drier air in place. With sfc high pressure over the
northeast Atlantic coast, we will also feel the benefits of cold
air damming from the Appalachians. Daytime highs will be in the
70s with lows in the upper 40s and 50s each night. Some of the
coolest air of the season is expected Friday night as lows sink to
the upper 40s across a larger portion of the area. The only
potential impact during this time period will be the chance for
patchy fog in and around river valleys and sheltered locations.

.LONG TERM...
(Saturday through Tuesday)
Issued at 1244 PM CDT Wed Oct 8 2025
Global models continue to indicate that a developing 500-mb
trough (initially positioned along the southeastern Atlantic
Coast) will continue to intensify as it lifts north-northeastward
this weekend. This disturbance may then become absorbed within the
flow around a more compact northern stream trough digging
southeastward from the Great Lakes, with this evolution resulting
in the formation of a large closed low in the general vicinity of
the Mid-Atlantic Coast. With NNW winds aloft predicted to increase
into the 25-35 knot range between the low to our east and a
500-mb ridge extending from south TX into the Great Lakes, we
expect dry conditions to prevail through the period. Highs will
slowly warm from the 75-80F range on Saturday into the l-m 80s by
Tuesday, with lows also increasing from the 45-50F range Sunday
morning into the l-m 50s early next week.

(18Z TAFS)

Breezy northeast winds will be the main impact this afternoon as
the MVFR stratus deck begins to erode. Gusts up to 20kts will
remain possible through the remainder of the day. No fog is
forecast through the TAF period.
