.SHORT TERM...
(Sunday through Monday)
Issued at 139 AM CST Sun Dec 22 2024

Surface high pressure across the region to shift east today. The
combination of the retreating high and a deepening surface low
just east of the Rockies will allow for southeast winds to
increase areawide, with the highest values near 10 mph across
northeast Texas and southeast Oklahoma. With winds becoming
southeast, temperatures to gradually warm areawide with highs
today in the mid to upper 60s and above freezing overnight lows
tonight in the mid 30s to mid 40s.

On Monday, warming trend to continue with afternoon highs in the
in the low to mid 60s areawide. Additionally, near zonal flow
aloft ahead of an approaching trough across west Texas will allow
for enough instability to support elevated isolated convection
across southeast Oklahoma and northeast Texas by late Monday
afternoon. /05/

.LONG TERM...
(Monday Night through Sunday)
Issued at 139 AM CST Sun Dec 22 2024

A progressive pattern expected through much of the long-term
period characterized by a series of upper-level disturbances and
surface boundaries swinging east across the ArkLaTex mainly on
Tuesday evening into the overnight hours and again on Thursday
evening into the overnight hours. The stronger of these two
disturbances appears to be the Thursday evening system, which
could result in a low-end severe thunderstorm threat depending on
available moisture return and the extent of destabilization that
may occur ahead of the low-amplitude broad trough that will
approach from the west.

Rain chances to linger through Friday into Saturday as upper-
trough ejects northeast leaving the ArkLaTex within a broad
southwest flow regime above an abandoned frontal boundary. Periods
of mainly scattered showers and isolated thunderstorms will be
possible. Otherwise, temperatures throughout the long term period
to range from highs in the mid 60s to lower 70s with lows in the
50s each day. /05/

.AVIATION...
(06Z TAFS)
Issued at 1059 PM CST Sat Dec 21 2024

For the 22/06Z TAF period, VFR conditions will prevail as mostly
SKC continues to dominate our airspace. Some cumulus will return
during the latter half of the period as sfc/low-level flow veers
more SE between 5-10 kts on Sunday. Otherwise, expect lgt/vrbl
winds this evening and through the overnight hours with continued
SKC through daybreak before clouds begin to increase from the west
throughout the day.
