 - Severe weather and heavy rain expected tonight. Very strong
   winds possible with expected storm complex across the south.

.NEAR TERM...
(Rest of today and tonight)
Issued at 251 PM CDT Sun May 25 2025

Will keep this quick as we are already turning to warning
operations. Severe storms are expected to and are starting to
develop. The most widespread severe threat will be from a complex
of storms expected to develop in the southern Texas panhandle and
the Texas South Plains then spread east into western north Texas
and potentially southwest Oklahoma. The environment looks
favorable for a bow echo to develop with the potential of very
strong winds and very heavy rainfall. Winds over 75 mph are
certainly possible. Other scattered storms may also develop east
of this developing complex, and near a residual outflow boundary
across Oklahoma, and indeed one supercell has developed over the
Arbuckle Mountains. Large hail, wind and perhaps an isolated
tornado will be possible with the more isolated storms east of the
complex.

Heavy rainfall will also be an issue as storms become more
widespread and move across the area this evening and overnight.

&&

.SHORT TERM...
(Monday through Tuesday night)
Issued at 251 PM CDT Sun May 25 2025

At least a marginal severe weather risk persists into Monday.
Precipitation chances will remain relatively high Monday as the
large scale mid-level trough moves approaches the area. But the
specifics in where rain will occur and where severe weather
potential will be will depend heavily on how the overnight storms
affect the low-level thermodynamics. Precipitation chances
decrease west to east across the area Monday night and early
Tuesday as the mid-level trough moves over and then east of the
forecast area.

&&

.LONG TERM...
(Wednesday through Saturday)
Issued at 1207 AM CDT Sun May 25 2025

Active upper pattern continues through late week, with at least low
rain chances each day. Temperatures will be mainly in the 70s,
warming to the 80s by the weekend.

&&

.AVIATION...
(18Z TAFS)
Issued at 1153 AM CDT Sun May 25 2025

Generally scattered to broken cumulus fields early this afternoon
with ceilings around 2,500-4,000 feet. Storms will develop in
western north Texas by mid afternoon and move eastward across the
Red River region, with more scattered development expected along
and north of I-40. Gusty winds, very heavy rainfall, and low
visibilities are likely with these storms. A cold front will move
through most of the area by morning, with IFR ceilings and some fog
potential along with winds shift to northeasterly.
