Areas affected...central/eastern OK

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

Valid 240436Z - 240530Z

Probability of Watch Issuance...40 percent

SUMMARY...Highly elevated convection across central Oklahoma may
yield an isolated, likely lower-end severe hail threat through the
early morning hours. A greater severe threat is expected to develop
out of Kansas later in the morning.

DISCUSSION...Highly elevated convection that appears to be rooted
around 700 mb has increased across central OK over the past half
hour. CAMs that well-simulated this development such as the 00Z
NSSL-MPAS and 02Z RRFS indicate that cells may struggle to greatly
intensify despite the presence of very steep mid-level lapse rates
and ample elevated buoyancy. This may be due to weaker effective
bulk shear for parcels rooted near 700 mb. As such, there is
uncertainty regarding how sustained a large hail threat may be. An
MCS still appears likely to emanate out of southwest and
south-central KS later in the pre-dawn hours, which should result in
a greater severe risk for north-central to northeast OK.
