   Mesoscale Discussion 1902
   NWS Storm Prediction Center Norman OK
   0713 PM CDT Mon Oct 25 2021

   Areas affected...Middle Atlantic

   Concerning...Severe Thunderstorm Watch 535...

   Valid 260013Z - 260145Z

   The severe weather threat for Severe Thunderstorm Watch 535
   continues.

   SUMMARY...Squall line will propagate across ww535 this evening.
   Damaging winds remain the primary threat.

   DISCUSSION...Exit region of mid-level speed max appears to be partly
   responsible for maturation of squall line that extends from northern
   VA into central NC. Although the linear MCS is not moving that fast,
   individual bow-type structures (Buckingham County VA) are surging
   east-northeast around 35kt. This activity is currently propagating
   across the maximum instability gradient so updraft intensity will
   likely be most efficient over the next few hours. Locally damaging
   winds remain the primary threat.
