   The severe weather threat for Tornado Watch 563 continues.

   SUMMARY...Isolated wind damage and perhaps a brief/weak tornado will
   remain possible as a squall line moves eastward across eastern AR
   and northern LA over the next couple of hours.

   DISCUSSION...Radar mosaic shows an extensive squall line from
   northeast AR south-southwestward into north-central LA as of 1240am
   CDT.  Surface analysis indicates the low-level moisture plume
   featuring rich moisture becomes increasingly pinched from a
   west-east standpoint with northward extent in southeast AR.  The
   orientation of the squall line is most favorable for wind-damage
   potential across the I-40 corridor in eastern AR where the kinematic
   fields are impressively strong.  However, buoyancy becomes
   increasingly marginal within this corridor per slightly cooler
   surface temperatures and dewpoints (near 70 deg with lower 60s
   dewpoints) compared to farther south over far southeast AR/northern
   LA where temperatures and dewpoints are appreciably higher.  Given
   the ongoing squall line's eastward progression over the next couple
   of hours, expecting the wind-damage risk to gradually move east and
   slowly lessen with time as it moves to the MS River.
