   Areas affected...North-central Arkansas

   Concerning...Tornado Watch 193...

   Valid 070829Z - 071030Z

   The severe weather threat for Tornado Watch 193 continues.

   SUMMARY...A wind damage and isolated tornado threat will likely
   continue across parts of north-central Arkansas late tonight. A
   watch extension is planned to the east of WW 193.

   DISCUSSION...Latest hi-resolution radar imagery from Little Rock
   shows a well-developed and intense short line segment over
   northwestern Arkansas. These storms are located along the
   northeastern edge of moderate instability, where the RAP is
   analyzing MLCAPE in the 1500 to 2000 J/kg range. The RAP also is
   analyzing a 50 to 60 knot low-level jet over far northwestern
   Arkansas, which is likely impacting this convection. The latest
   WSR-88D VWP at Little Rock, AR has 0-6 km near 50 knots and 0-3 km
   storm-relative helicity around 650 m2/s2. This environment will
   likely continue to support bowing line segments with embedded
   rotation and tornado potential. Wind damage will also be likely
   along the leading edge of any bowing segment. The threat will affect
   ares to the north of Little Rock within an hour or two. The watch
   will be extended to the east of WW 193 to account for the increased
   severe potential.
