.DISCUSSION...
Issued at 1228 AM CST Sun Nov 9 2025
An anomalously strong longwave trough is expected to dig into the
eastern US over the next 24 to 48 hours. This will help to push a
potent cold front through the local area this afternoon, allowing
for the first arctic airmass of the season to filter through the
Deep South and into the Gulf. For the remainder of the overnight and
into the morning hours, weak moisture pooling, limited forcing,
and some elevated instability may allow for a few showers or
possibly a thunderstorm, to develop ahead of the front (rain
chances around 20-30%). Once the front passes, rain chances drop
to zero as much colder and drier air will advect in from the
northwest. Given the strong gradient, winds behind the front will
also be on the increase, with gusts this afternoon potentially as
high as 25- 30mph in spots. Highs today will range from the upper
60s to low 70s west of I-65 to the mid to upper 70s for areas
east, but with the progression of the front, these highs will
likely occur during the mid to late morning hours, with temps
lowering throughout the afternoon.
Bitter cold temperatures/wind chills are expected across the area
from Sunday night through Tuesday night. Lows Sunday night will
likely drop into the 30s areawide, with maybe a few locations along
the immediate coast staying in the low 40s. Winds will remain rather
gusty Sunday night, which should keep our area just above the
freezing mark (with the exception of a few localized areas in our
far northern counties). However, factoring in the wind chill, it
will likely feel like the mid to upper 20s for most of the area,
and low 30s along the coast. For Monday, even under sunny skies,
the continued gusty winds/strong cold air advection will likely
keep highs in the upper 40s to low 50s. By Monday evening and into
Monday night, winds will finally begin to relax as high pressure
moves overhead. Light winds, dry conditions, and clear skies, will
lead to efficient radiational cooling, likely causing
temperatures to plummet into the 20s for areas north of I-10. Even
areas south of I-10 may also drop to below freezing. In fact, NBM
probabilities for lows less than 32 degrees have increased even
further during the latest run, ranging now from 50-70% along the
coast. Therefore, it is looking increasingly likely that a Freeze
Watch will need to be issued for the entire CWA in the next
forecast package. Daily record lows are also in jeopardy of being
broken at our local climate sites (KMOB record: 31 degrees; KPNS
record: 33 degrees), with the NBM giving a greater than 75%
probability of each location breaking their respective records.
Additionally, although winds are expected to be light Monday
night, there may be enough of a wind chill factor to support the
need for a Cold Weather Advisory for apparent temperatures
dropping into the upper teens to low 20s. Reiterating what the
previous shift stated, given the relatively abrupt and early
nature of this cold compared to normal, as well as the fact that
we were recently in the 70s and 80s, we are not yet acclimated to
this degree of cold weather, which could lead to a more dangerous
risk for vulnerable communities. We urge residents and visitors to
make preparations to protect people, plants, pets, and pipes from
this cold weather.
After one more day of chilly temperatures on Tuesday, with highs in
the 50s and lows ranging from the mid 30s inland to the low 40s
along the coast, the high will shift to our east, allowing for winds
to turn onshore. Although we remain dry through the remainder of the
extended period, temperatures will rise back to above seasonal
norms. Highs for late week will top out in the low to mid 70s and
lows will range from the mid 40s inland to mid 50s along the coast.
A Low Risk of rip currents remains in place through the period. /96

(18Z TAFS)
Issued at 1134 AM CST Sun Nov 9 2025
Gusty northwest winds are expected through Monday morning in the
wake of a cold front currently over the western Florida panhandle
and soon to exit the area. An MVFR deck mainly located along and
east of I-65 improves to VFR through this afternoon. Gusty northwest
winds 10-15 knots persist through tonight then increase to 10-20
knots Monday morning. /29

.MARINE...
Issued at 1228 AM CST Sun Nov 9 2025
Moderate southwesterly to westerly winds this morning will become
a strong northwesterly flow by the late afternoon hours in the
wake of a strong cold front and will persist through Monday
night. A Small Craft Advisory is in effect from this afternoon
through Monday night for all local marine zones. Occasional gusts
to gale force are possible over the open Gulf waters Sunday night
into Monday morning. Winds will then relax on Tuesday and become
a light onshore flow by Wednesday. /96
