Areas affected...Central OK

Concerning...Severe potential...Watch unlikely

Valid 261824Z - 261930Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated hail is possible across central OK through early
afternoon. A more robust severe threat is anticipated later this
afternoon.

DISCUSSION...Recent radar and satellite trends have shown an
increase in elevated convection over the last hour. This activity
initiated near the leading edge of the increasing low to mid-level
moisture  (depicted well by the mesoanalysis at 850 mb) and appears
to be rooted somewhere between 700 and 800 mb. Gradually increasing
mid-level flow coupled with steep mid-level lapse rates will likely
result in some modest organization of these storms, which could
result in isolated instances of severe hail. However, these storms
will move northeastward into a less favorable thermodynamic
environment, suggesting strongest updrafts may not persist beyond
the next hour or two. A more robust, surface-based threat is
expected during the late afternoon farther southwest near the I-44
and I-35 corridors.
