   Concerning...Tornado Watch 700...

   Valid 030754Z - 030930Z

   The severe weather threat for Tornado Watch 700 continues.

   SUMMARY...The threat for tornadoes, both within cells ahead of the
   convective line and within the convective line itself, will persist
   for at least the next few hours. Tornado Watch 700 was recently
   issued across central and eastern Oklahoma to address this threat.

   DISCUSSION...Several discrete supercells have matured within the
   open warm sector across central OK. This includes the supercell over
   Stephens County, which had a rotational velocity over 65 kt for
   several scans within the last 25 minutes. The maturing of these
   cells corresponded with the strengthening of the surface winds by 5
   to 10 kt within the warm sector, with southeasterly winds now
   gusting 20 to 25 kt. The longevity of these discrete cells will be
   limited by the approaching convective line, but the persistence of
   strong low-level flow suggests the tornado threat will likely
   persist within the line itself as it continues eastward. Given this
   continued threat for tornadoes in both discrete cells ahead of the
   line and QLCS circulations within the line, a Tornado Watch was
   recently issued for central and eastern OK. The airmass ahead of the
   line is expected to remain at least modestly unstable into eastern
   OK, justifying its inclusion in the recent watch.
