and possible warnings.
Other watch information... continue... ww 189... ww 190...
Discussion... rapid intense storm development is expected during the
next few hours... both near a stalled surface front roughly west of
the I-35 corridor... and near the pre-frontal dryline nosing
northeastward into south central Oklahoma by late afternoon.
Isolated supercells are likely along the dryline... with the most
prominent tornado threat... which probably will increase by early
evening as the southerly low-level jet strengthens and enlarges
low-level hodographs. One or two strong tornadoes may not be out of
the question. Otherwise... large hail is likely... some very large...
with increasing damaging wind potential across eastern Oklahoma as
convection consolidates and evolves into an organized cluster.
Aviation... tornadoes and a few severe thunderstorms with hail
surface and aloft to 4 inches. Extreme turbulence and surface
wind gusts to 60 knots. A few cumulonimbi with maximum tops to
600. Mean storm motion vector 25035.
