.DISCUSSION...
(This afternoon through next Saturday)
Issued at 1137 AM CST Sun Dec 28 2025

Warm and windy conditions are on display across the Mid-South as
of 11 AM. A Wind Advisory will go into effect for all of eastern
Arkansas, the Missouri Bootheel, West Tennessee, and portions of
north Mississippi at noon today. As the pressure gradient
tightens ahead of a low pressure system, sustained winds will be
around 20-25mph and gust up to 45 mph.

The aforementioned low pressure system will sweep a cold front
across the area tonight and bring continued gusty conditions,
rain showers, and a pattern change. Gusty conditions will enhance
to around 45 mph with this line across the Wind Advisory area.
Showers and enhanced wind conditions will be arriving from the
northwest this afternoon. There is a very low chance (15% or
less) of a thunderstorm today. Instability is lacking with a 20-
30% chance of exceeding 500 J/kg of SBCAPE. Point and click
soundings also depict a very stable near surface layer (~4C/km)
and conditionally unstable (6C/km) aloft. With these parameters,
severe thunderstorms are unlikely to develop. Despite the very
low chance (15% or less), a stray rumble of thunder could occur
across northeast Arkansas during the line of showers initial
approach. Gusty winds are the primary concern this afternoon and
evening.

The air behind the cold front is of arctic origin and will dip
Monday and Tuesday morning lows below freezing. Tuesday morning
has a high chance (>70%) of temperatures below 28F area wide
under clear skies and the cool air finally sinks to the surface.
Both Monday and Tuesday will be cool temperature wise, but brisk
northerly winds will bring the "feels like" temperatures into the
teens and 20s. This cold snap will not last long as southerly
flow will return Wednesday afternoon and advect warmer air back
to the region. Near normal temperatures will ring in the New Year
with daytime temperatures in the upper 40s and 50s and morning
lows in the 30s and 40s. Temperatures will gradually rise above
normal by the first weekend of January ahead of the next weather
system.

MVFR conditions will remain across the airspace through early
evening, ahead of a strong cold front. The pressure gradient out
ahead of this aforementioned front will remain tight through the
TAF period, resulting in gusts up to 35 kts across all terminals.

around 23Z through about 05Z. Behind showers and the front,
southwest winds will shift north/northwest, but winds will remain
gusty, up to 30 kts.

.FIRE WEATHER...
Issued at 1137 AM CST Sun Dec 28 2025

Minimum RH values will remain above 50% through the weekend. A
cold front will bring much drier air Monday dipping these values
between 30-40%. The frontal boundary is expected to bring wetting
rain conditions areawide, but winds will remain gusty. A limited
fire danger threat will loom through late week as dewpoints will
struggle to exceed 30F.
