   Concerning...Tornado Watch 138...

   Valid 261235Z - 261430Z

   The severe weather threat for Tornado Watch 138 continues.

   SUMMARY...Severe thunderstorms including the potential for primarily
   damaging winds and a couple tornadoes continues across eastern
   Oklahoma, and may develop into far western Arkansas and possibly
   southwest Missouri. Tornado Watch 138 continues for eastern
   Oklahoma, and downstream Arkansas/southwest Missouri areas are being
   monitored for possible but uncertain Watch issuance in the short
   term.

   DISCUSSION...A well-organized squall line with
   LEWP/northern-peripheral bowing characteristics continues across
   eastern Oklahoma, with bow-related northeastward storm motions
   around 50 kt. The most intense portion of the squall line and
   greatest short-term severe risk should be focused where the
   convective line intercepts the warm front (and just a bit north
   thereof) in the general vicinity of I-40 in far eastern Oklahoma
   into west/northwest Arkansas. Farther north, the severe-potential
   longevity of the surging bowing portion of the line is a bit more
   uncertain with northward extent, given that the bowing line will
   gradually encounter an increasingly more stable boundary layer (0.5
   km AGL deep per 12z Springfield MO observed sounding).
