   The severe weather threat for Severe Thunderstorm Watch 356, 361
   continues.

   SUMMARY...Severe wind gusts remain the primary concern across Severe
   Thunderstorm Watches 356 and 361.

   DISCUSSION...A mature convective line across parts of northern Ohio
   will continue tracking east-southeastward at around 50 kt into the
   overnight hours, while an additional convective cluster farther west
   over northwest Ohio continues southeastward at around 35 kt. Farther
   south, a large cold pool is evident over parts of WV in the wake of
   a now decaying MCS moving into far western VA. North of the cold
   pool, a narrow corridor of rich boundary-layer moisture (lower 70s
   dewpoints) and surface-based instability remains in place. Given
   that inflow will likely be rooted at or near the surface along this
   corridor, effective bulk shear near 30-40 kt perpendicular to the
   convective line could support its maintenance toward the southeast.
   Trends will continue to be monitored, and a new watch could
   eventually be needed downstream of Severe Thunderstorm Watch 361.
