Areas affected...Central to southern Oklahoma

Concerning...Severe potential...Watch possible=20

Valid 231844Z - 232045Z

Probability of Watch Issuance...40 percent

SUMMARY...An uptick in thunderstorm coverage is expected over the
next 1-2 hours as outflow boundaries begin to collide. Storms may be
capable of large hail and severe gusts. Watch issuance may be
needed.

DISCUSSION...Two outflow boundaries are apparent in surface
observations and radar imagery across central OK. Recent development
along the northern outflow boundary near/west of the OKC metro has
produce a strong wind signature with observed gusts between 50-60
mph per Mesonet observations. Additionally, MRMS VII trends show
periodic severe hail signals. Given a nose of 1500-2500 J/kg MLCAPE
in place ahead of both outflow boundaries, additional thunderstorm
development appears likely in the next couple of hours. 30-35 knot
0-6 km BWD values observed at KILX ahead of the boundaries suggests
storms may see transient organization with an attendant hail/wind
threat prior to destructive interference from neighboring cells
and/or cold outflow. The expected transient nature of the convection
(similar to what is being observed across southern OK) casts
uncertainty on whether the severe threat will be sufficiently
prolonged and/or widespread to warrant additional watch issuance
and/or expansion of WW 380.
