.DISCUSSION...
(Tonight through next Monday)
Issued at 1046 PM CST Mon Nov 17 2025

Low pressure is situated over the Central Plains this evening
with a warm front extending southeast into the Lower MS Valley. A
weak shortwave that had generated a few showers over West TN this
evening is quickly moving east. The last of its associated
showers are crossing the TN River into Middle TN. Temps range from
the mid 50s to lower 60s. Readings will fall to around 50 by
Tuesday morning along the TN River where the airmass is dry and
winds are lighter. Temps will level out across the Delta thanks to
steady south winds.

Low pressure will track to the Mid MS Valley by early Tuesday and
into the OH Valley by Tuesday evening. Most of the showers and
thunderstorms associated with this system will remain north of the
KY/MO/TN border. Northern parts of the Mid-South could see
isolated to scattered showers and thunderstorms after midnight
through about noon Thursday as the warm front lifts through. Much
warmer air will flood into the Mid-South on gusty SW winds. Wind
gusts above 30 mph will be common Tuesday afternoon, especially
across the Delta. Values should remain below Wind Advisory
criteria though. Near record temps are expected across north MS.

As the surface low moves across KY Tuesday night, a weak cold
front will sag into the Mid-South. Latest CAMS show isolated to
scattered convection developing along this feature during the
evening, continuing into the overnight hours. Forecast soundings
indicate some elevated instability and a little shear. Boundary
layer moisture quality is pretty poor and lift is weak so the
severe threat is minimal but worth watching.

Upper ridging will strengthen on Wednesday ahead of the next
system. The weak cold front will become a stalled boundary across
the Mid-South. Temps will be cooler toward the KY/MO border and
very warm south of the boundary, across north MS, where record
highs will likely be challenged.

The next system will exit the SW US on Thursday with moist SW
flow increasing across the Mid-South. Expect overrunning to
develop along the stalled frontal boundary that will start
lifting north as a warm front. Numerous to widespread showers and
thunderstorms will develop along that frontal boundary across
mainly areas along and north of I-40 Thursday into Thursday night.
The cold front will push into the region on Friday with more
showers and thunderstorms. A severe threat could develop depending
on timing and how the instability fields unfold. The system seems
to be favoring a more progressive evolution so heavy rainfall
looks like less of a problem. Storm total rainfall amounts of 1 to
2 inches are expected with higher amounts north of I-40.

Latest models are settling on the next bit of energy moving into
the SW later this weekend remaining cutoff this weekend and
ejecting east more slowly. This should result in some upper
ridging developing across the Southern Plains and possibly a dry
and seasonable weekend across the Mid-South.

(12Z TAFS)
Issued at 541 AM CST Tue Nov 18 2025

A warm front will push north across the area today with a 20-30
percent chance of MVFR ceilings developing at all sites except
TUP. Otherwise, VFR conditions should prevail into this evening.
There is a 20-30 percent chance of a rain shower affecting JBR and
MEM this evening as the boundary returns back south as a weak
cold front. Latest ensemble guidance trends suggest MVFR ceilings
re-developing overnight across the area. S winds will increase to
10-16 kts with gusts up to around 25 kts during the day.

.FIRE WEATHER...
Issued at 1046 PM CST Mon Nov 17 2025

the period.
