.NEAR TERM...
(Rest of today and tonight)
Issued at 203 PM CDT Wed May 28 2025

A Mesoscale Convective Vortex (MCV) continues to move across
portions of the eastern Texas Panhandle today, which is helping to
bolster thunderstorm development across western north Texas and
far southwestern Oklahoma. As this MCV moves towards the east,
expect thunderstorm development to decrease through the afternoon
hours.

A complex of strong to severe storms will move into northwest
Oklahoma from the high Plains later this evening. This activity
will move towards the south and east through the night and into
the morning hours. Elevated instability of up to 2000 J/kg and a
strong (~40 kt) low-level jet will help to at least sustain the
convection through a majority of the area. The strongest cores
within this line of storms will have the potential to produce
damaging winds and large hail. A very low tornado risk will exist,
mainly across the northwestern third of the area, where the
storms are expected to be the strongest. As storms move towards
the southeast into central Oklahoma, they are expected to weaken.

.SHORT TERM...
(Thursday through Friday night)
Issued at 203 PM CDT Wed May 28 2025

Any remnant convection Thursday morning is expected to continue
to weaken through the morning. A cold front will push through the
area during the day. Highs behind the front will be cooler,
generally in the low to mid 70s. There is a low chance for
additional thunderstorms to impact southern portions of the area,
but will depend on the evolution of the front.

Friday appears to offer a break from storm chances as surface
high pressure settles over the area and moisture gets displaced to
the south by the front. Highs will be in the upper 70s with
plenty of sunshine and relatively light winds, making for an
overall beautiful day.

Bunker

&&

.LONG TERM...
(Saturday through Tuesday)
Issued at 312 AM CDT Wed May 28 2025

Storm chances this weekend are uncertain as models diverge on the
strength/timing of shortwave energy moving through northwest flow
aloft. But a general increase in instability along with upslope
flow across the high plains could lead to storm chances for at
least parts of the area Saturday and/or Sunday night.

Flow aloft is forecast to become southwesterly early to middle of
next week as western US troughing develops. This should lead to a
sharpening dryline and additional storm chances for parts of the
area, with an attendant uptick in severe weather potential.

.AVIATION...
(00Z TAFS)
Issued at 615 PM CDT Wed May 28 2025

VFR/MVFR ceilings this TAF period. Complex(es) of showers/storms
expected to move into NW OK this evening and then continue to move
across portions of the area into early Thursday. Additional storms
will be possible tomorrow. Some of the storms tonight could
produce strong variable winds and hail. A frontal boundary is
expected to move across the area Thursday causing winds to shift
towards the north. However, any outflow boundary associated with
the storm complex could also cause shifting winds before the front
moves through the area.
