.SHORT TERM...
(Through tonight )
Issued at 1250 PM CDT Mon Oct 6 2025

As of early this afternoon, a weak frontal boundary was positioned
from the Texas Panhandle through northwest Oklahoma and eastern
Kansas up northeast into the Great Lakes region. Along this
boundary scattered showers and thunderstorms were ongoing within
an area of warm advection and deeper mid level moisture. At the
same time, an area of low pressure was lifting north/northeast
from southern Arkansas with scattered rain showers on the
northern/eastern side of the disturbance. Between these two
features, increasing cloud cover was observed across eastern
Oklahoma and northwest Arkansas with temps warming above the
seasonal average.

Through this evening, the weak frontal boundary is expected to
slowly sag southeast nearing the CWA, while the area of low
pressure continues its track off to the northeast. Before the
disturbance begins to push away from the region, there remains low
chances for isolated to widely scattered showers/storms to spread
into northwest Arkansas and far eastern Oklahoma. Mid to late
evening, the low should be moving into eastern Arkansas, and as
such precip chances for the eastern half of the CWA should taper
off. Severe weather is not expected with this activity.

Overnight tonight, a shortwave currently over the Rocky Mountains
is progged to move eastward out into the Plains and help push the
weak frontal boundary into the CWA. A slight chance of rain/storms
develops along and near the Oklahoma Kansas border tonight and
remains forecast into Tuesday morning with the boundary moving
southeast through the region. Ahead of the boundary tonight,
increasing low level moisture and light winds will aid in the
potential for fog development across southeast Oklahoma and
northwest Arkansas. Meanwhile, behind the boundary, breezy
northerly winds and widespread cloud cover are expected to spread
across northeast Oklahoma. Low temperatures tonight in the upper
50s to upper 60s from north to south are forecast.

.LONG TERM...
(Tomorrow through Monday)
Issued at 1250 PM CDT Mon Oct 6 2025

The weak boundary moves through the CWA during the day Tuesday
with northerly winds spreading over the region. Will hold onto a
slight chance of showers/storms for parts of northeast Oklahoma
Tuesday morning before the mid level shortwave exits the Plains.
Otherwise, mostly cloudy and cooler conditions are anticipated
across the northern half of the CWA. Across the southern half of
the CWA, a slight chance of rain/isolated storms remains Tuesday
afternoon, though latest indications continue to trend a weaker
signal for afternoon precip across the CWA. High temperatures
Tuesday will be tricky with the cloud cover and the movement of
the boundary. For this forecast highs around 70 deg near the
Kansas border to the mid 80s near the Red River look probable.

The cooler conditions and east/northeast winds are forecast to
continue Wednesday while the region remains in a nearly zonal
mid/upper level flow. However, these conditions look to be short
lived as latest model solutions continue to reestablish the ridge
of high pressure over the Southern Plains Thursday through the
weekend. Model solutions have trended back toward eastern
Oklahoma and northwest Arkansas being more underneath the ridge
compared to yesterday where the CWA was on the eastern periphery.
Thus, any shortwave engorge rounding the top of the ridge Friday
now looks to remain to the northeast of the CWA. These conditions
will allow for a warming trend to develop Thursday with above
seasonal average temperatures returning through the weekend. At
this time, forecast high temperatures are mid 80s to near 90 deg
with lows in the 50s/60s. Late weekend, breezy southerly winds
develop ahead of another shortwave looking to move into the
Plains. These winds and the warm temperatures could increase fire
weather dangers for parts of northeast Oklahoma Sunday afternoon.

.AVIATION...
(18Z TAFS)
Issued at 1250 PM CDT Mon Oct 6 2025

VFR conditions are expected through the afternoon and into the
evening hours for all sites, with the exception of a chance at a
shower or thunderstorm across western Arkansas sites through 00Z. A
shallow cold front will move through the region form north to south
overnight tonight into tomorrow morning, bringing a shift to
northerly winds with some gusts around 20 knots possible for several
hours behind the front. Additionally low clouds will  filter in
behind the front, especially from near I-40 north. MVFR ceilings are
likely with some IFR cigs possible across NW AR sites or along the
OK/KS border. Before the front arrives, some patchy fog will also be
possible across NW AR sites with any fog clearing up after passage
of the front and an increase in wind speeds.
