.SHORT TERM...
(Through tonight )
Issued at 1200 PM CDT Tue Apr 28 2026

Showers and thunderstorms are ongoing early this afternoon as an
upper wave passes overhead. Large hail and damaging wind gusts will
continue to be the primary hazards associated with storms north of a
warm front in southeast Oklahoma and NW AR. Along and south of the
warm front, all severe hazards will be possible. Over time, the
front will be forced back to the south with a decreasing
thunderstorm and severe threat for our area.

&&

.LONG TERM...
(Tomorrow through Tuesday)
Issued at 1200 PM CDT Tue Apr 28 2026

Precip ends entirely by tonight with high pressure filling into the
region for Wednesday. This provides a break in the active weather
pattern with drier and cooler conditions. Rain chances increase
again late in the day Thursday as moist SW flow overruns the
region ahead of an approaching western trough. This system
eventually ejects east Friday into Friday evening with continued
precipitation chances, mainly near and south of Interstate 40.
Instability will be lacking with this feature and little in the
way of thunder is expected with no severe threat. This weekend
looks quiet weather-wise with near average temperatures returning
by Sunday. Eastern troughing sets up for early next week with a
weak disturbance providing low rain and thunder chances Monday
night into Tuesday. For now, the severe weather potential through
the extended period looks to remain low.

Issued at 1230 PM CDT Tue Apr 28 2026
