   The severe weather threat for Tornado Watch 515 continues.

   SUMMARY...Tornado threat continues across central and eastern
   Arkansas.

   DISCUSSION...TS Beryl circulation has progressed into northeast TX,
   just southwest of Texarkana, and is gradually weakening as it ejects
   northeast into the lower MS Valley. Strongest low-level shear is now
   focused across central AR where 0-3km SRH at LZK is on the order of
   650 m2/s2. Even so, low-level shear has gradually decreased ahead of
   this feature, and nocturnal cooling is notably affecting buoyancy in
   the lower troposphere. As a result, supercell structures are
   considerably fewer than earlier this evening, though several
   embedded longer-lived circulations are noted within a larger cluster
   of convection currently lifting north across central AR. Tornado
   threat continues with this activity and a local extension to Tornado
   Watch 0515 may be needed by 05z.
