.SHORT TERM...
(Wednesday through Thursday)
Issued at 133 AM CST Wed Feb 5 2025

A weak frontal boundary lingering across northeast Texas into
southeast Oklahoma and southwest Arkansas will maintain low-level
instability across the region. The combination of the front and a
moist airmass, characterized by dewpoint values in the 60s, has
allowed for areas of fog across the region with some locations
experiencing reduced visibility values as low as 1/4sm. Therefore,
a Dense Fog Advisory is in effect through mid-morning across much
of northeast Texas, northwest Louisiana, and southwest Arkansas.
At this time, will hold off on extending the advisory south due to
the lack of observations currently supporting an advisory along
with the displacement of these locations from the front.

Conditions will be slow to improve through the morning, with
mostly cloudy skies expected areawide. As temperatures climb into
the upper 70s today, low ceilings forecast to dissipate. However,
could see a few showers developing across the region due to
marginal instability in response to weak southwest flow aloft and
the lingering frontal boundary.

Pressure gradient to increase tonight allowing for south winds to
remain elevated from 5 to 10 mph, which should be enough to mitigate
any dense fog concerns. Lows tonight are forecast to fall into
the mid 60s.

On Thursday, upper flow to remain nearly zonal with frontal
boundary sinking into northeast Texas and south Arkansas. Could
see a few showers along the front during the time of afternoon
heating. Otherwise, highs on Thursday to climb into the upper 70s
to lower 80s. /05/

.LONG TERM...
(Thursday Night through Wednesday)
Issued at 133 AM CST Wed Feb 5 2025

Pattern to remain nearly unchanged through Saturday as the frontal
boundary lingers across Arkansas and northeast Texas. Could see a
chance of showers each day across these areas, as well as
southeast Oklahoma. Temperatures through the end of the week into
Saturday will range from highs in the upper 70s to lows in the
low to mid 60s.

High pressure to dive south across the region on Saturday night
into Sunday bringing much cooler temperatures to the region.
Post-frontal widespread precipitation is expected to develop
on Sunday afternoon, with periods of rain continuing through the
end of the forecast period on Wednesday. The higher rain totals
can be expected mainly south of I-20.

Much colder temperatures expected late in the weekend into early
next week with highs averaging in the 50s and lows in the 30s and
40s. By Wednesday morning, could see temperatures dip to near
freezing across the I-30 corridor. At this time, precipitation
should remain south of these areas within an airmass that will
remain above freezing, posing no significant wintry impacts. /05/
