.DISCUSSION...
Issued at 946 AM CST Mon Nov 17 2025

Morning fog resulting from the prevailing warm and moist airmass
to continue to erode with lingering low clouds to persist
throughout the day. High temperatures are forecast to climb into
the lower 80s areawide. A stationary frontal boundary across the
region will lift north as a warm front this afternoon, lifting
into Arkansas by midnight tonight. Additionally, a surface cold
front will swing east into Oklahoma. Upper-level flow will be
mainly westerly with enough forcing in the warm sector ahead of
the cold front to allow for a chance for a few stray showers and
thundersorms, mainly across south Arkansas and southeast Oklahoma
this evening.

Weak upper-level ridging to maintain dry conditions through
Tuesday. Southerly flow resulting from a surface high across the
southeast will also continue to maintain warm conditions with
afternoon highs in the lower 80s areawide.

Pattern shift expected Wednesday night into Thursday as an upper-
trough across southern California begins to track east into the
Four Corners region through Thursday afternoon resulting
increased southwest flow across the ArkLaTex. Warm air advection
will further enhance destabilization ahead of the upper-trough. A
surface low deepening across Texas on Wednesday night into
Thursday will could serve as the trigger for widespread convection
across much of the ArklaTex from Wednesday night into Thursday.
Highest rainfall totals through this timeframe could average
around 3 inches  with isolated higher amounts across mainly
northeast Texas into Oklahoma and southwest Arkansas.
Additionally, some strong storms may be possible.

Conditions to gradually improve late Thursday night into Friday
as upper-flow becomes zonal behind a cold front exiting the
region to the east. Eastward moving upper-low across Oklahoma and
Missouri lagging behind the front could maintain lingering clouds
and scattered rain chances throughout the day on Friday.

Upper-level ridging to rebuild behind the front allowing for
mainly dry and stable conditions through the weekend. A cooler
airmass in place will allow for highs in the 60s to lower 70s and
lows in the upper 40s. /05/
