   1109 PM CDT Tue Apr 03 2018

   Areas affected...Central through northeast Alabama and northwest

   Concerning...Severe Thunderstorm Watch 35...

   The severe weather threat for Severe Thunderstorm Watch 35

   SUMMARY...Localized damaging wind gusts may remain possible with the
   remnant line of convection spreading toward the Interstate 85
   corridor through 1-4 AM EDT.  Additional watches to the east are not

   DISCUSSION...Lightning and radar data indicate notable weakening
   trends to convection extending south of the southern Tennessee state
   border during the past hour or so.  However, latest surface and
   objective analysis suggests that the boundary layer remains at least
   weakly unstable ahead of activity into the Interstate 85 corridor of
   east central Alabama and northwest Georgia.  With activity still
   embedded within 30-50 kt lower/mid tropospheric mean flow, it
   probably will continue to pose a risk for localized strong surface
   gusts until it dissipates later tonight.
