.NEAR TERM...
(Tonight)
Issued at 154 PM CDT Sun Oct 5 2025

Current satellite and surface observations show an area of mid
and high clouds gradually moving west from the Atlantic through
the deep south aided by gusty ESE winds. High pressure situated
over the mid Atlantic will remain dominate through the near term
forecast with ESE flow along the base of the high prevailing.
Through the night the ESE flow will advect in a decent amount of
moisture from the Atlantic with HREF models showing dew points
increasing from the mid to low 60s to the high 60s by day break.
Additional clouds will accompany the additional moisture with
partly to mostly cloudy conditions forecast through the night.
Unfortunately this will mean our relatively cool mornings will
come to an end tomorrow as the higher dew points and additional
cloud cover will restrict overnight lows to the mid to high 60s.

(Monday through Tuesday)
Issued at 1008 AM CDT Sun Oct 5 2025

The feed of moisture will persist Monday into Tuesday, especially
across western AL, MS through west TN, where showers and a few
thunderstorms will occur. Locally heavy rain amounts may occur
given the high PWs within this zone. Rain chances drop off
significantly further east of I-65. As the west-southwest 5h flow
pattern becomes more westerly on Tuesday, a weak surface-8h
boundary will drop southeast into TN through northern MS. This may
pivot the deep moisture field into a more southwest to northeast
fashion with 8h southerly flow to 15-20kt persisting. So a rather
persistent area of showers and thunderstorms will continue across
MS, northwest AL, TN and KY on Tuesday. No severe weather is
anticipated, but we will have to monitor trends of locally
excessive rainfall in these areas low to medium chances of showers
and thunderstorms Tuesday night.

.LONG TERM...
(Wednesday through Saturday)
Issued at 1038 PM CDT Sat Oct 4 2025

Upper level ridging now over the coastal Mid Atlantic will slowly
build to the SW during the early portion of next week. Troughing
that was producing unsettled weather over parts of the northern
Rockies should also weaken and move into Ontario/Quebec by the
mid week. This will essentially bring a more zonal upper flow
pattern across much of the Lower-48 towards the middle of next
week.

A cold front will be approaching the area and move across the
Tennessee Valley on Wednesday. With more clouds and low rain
chances (20-30%), highs temperatures for the mid week should be a
tad cooler into the upper 70s and lower 80s. A bit cooler Wed
night with lows in the upper 50 and lower 60s. An airmass change
will make for slightly cooler conditions for the second half of
next week, with highs in the mid 70s to around 80, and lows in the
mid 50s to lower 60s.

Limited lower level moisture return before the front moves across
the region, will help keep rain chances and amounts on the low
side. For the Thu-Sat timeframe, spotty rain chances should
continue Thursday, with Fri/Sat trending dry and worsen the on-
going drought.

.AVIATION...
(18Z TAFS)
Issued at 1144 AM CDT Sun Oct 5 2025

While a scattered to broken cloud deck will move in at the start
of the TAF, ceilings are forecast to remain VFR through the whole
TAF period. The most consequential parameter will be the gusty SE
winds the whole TAF period with gusts up to 25 this afternoon and
gusts near 15 overnight through tomorrow morning. Wind shear will
also be possible overnight at both terminals from around 6Z-12Z.
