.NEAR TERM...
(Rest of tonight and Sunday)
Issued at 919 PM CST Sat Nov 8 2025

The isolated showers seen across a convergent boundary earlier this
evening have since either dissipated or shifted to the east as upper
troughing and an associated cold front dig into the Deep South. That
will be the main influence on weather overnight as well as over the
next several days as we prepare for our coldest airmass since late
February. That said, with the front not expected to move through
until tomorrow morning our overnight lows will be on the warmer side
of normal in the mid to upper 40s. Gradient winds will increase as we
head toward the morning hours, especially in vicinity of and behind
the front with northwest gusts up to 30mph at times. We will hold off
on issuing a Wind Advisory for now due to current NBM and HREF
ensembles remaining below criteria. Even with high temps in the 50s
tomorrow, the gusty winds will make it feel more like the 40s so be
sure to bundle up if headed outdoors. Also be sure to secure any
loose outdoor items/decorations.

.SHORT TERM...
(Sunday night through Tuesday night)
Issued at 919 PM CST Sat Nov 8 2025

The upper trough and high pressure will continue to push potentially
record cold air (for early November) into the area. Overnight lows
will sink down below freezing area wide, ranging from the mid to
upper 20s. For that reason, the Freeze Watch has been upgraded to a
Freeze Warning Sunday night through Monday morning. With northwest
winds remaining breezy this will bring wind chills down into the
teens in some locations Monday morning... maybe even area wide.
Please remember to protect people, pets, pipes, and any sensitive
vegetation. Even colder air arrives on Monday as highs may not make
it much above 40 degrees putting record low max temps at risk of
being broken. Overnight lows will fall to the lower 20s putting the
record lows of 22 (HSV) and 19 (MSL) at risk of being broken Tuesday
morning as well. Winds will finally start to slacken Monday night as
gradient flow weakens and a warming trend will begin thanks to upper
ridging shifting east over the Plains. Winds will back to the
west/southwest as the sfc high passes to our south and we will head
toward the mid-week period with a dry forecast and warming
conditions.

.LONG TERM...
(Wednesday through Saturday)
Issued at 919 PM CST Sat Nov 8 2025

By midweek the longwave trough along the east coast will lift
northeastward and the shortwave behind it will slide across the
Great Lakes. This pattern will dampen the sfc high in place across
the Southeast, but that will be short lived as an amplified ridge
will build along the Rockies on Thursday. The ridge will slide
into the Plains on Friday and the axis will reach the TN Valley by
Saturday.

Wednesday`s southwesterly flow from the sfc high will rebound high
temps into the 60s, over 10 degrees warmer than those we will see
on Tuesday. Values will be just a tad higher on Thursday, and
with the increasing heights and continued sunshine, highs will
reach the 70s on Friday and Saturday.

.AVIATION...
(06Z TAFS)
Issued at 1102 PM CST Sat Nov 8 2025

VFR conditions are forecast through the TAF period at both KMSL
and KHSV. However, gusty northwesterly winds up to 25 kts are
forecast to affect both terminals tomorrow morning through the
evening hours. Additionally, there is a low chance of patchy fog
tonight into Sunday morning. Confidence is too low to include
this in the official TAF package.
