Areas affected...Southeastern New York/southern New England
southward to the Chesapeake Bay

Concerning...Severe Thunderstorm Watch 568...569...

Valid 292045Z - 292245Z

The severe weather threat for Severe Thunderstorm Watch 568, 569
continues.

SUMMARY...Strong/locally severe storms will continue across parts of
the Northeast and Mid-Atlantic regions over the next few hours.

DISCUSSION...Latest radar loop shows widespread thunderstorm
activity from northeastern Pennsylvania and southeastern New York
into parts of southern New England, with more isolated storms
extending southward to Maryland and northern Virginia.  The storms
are occurring within an airmass generally characterized by 1000 to
1500 J/kg mixed-layer CAPE, though instability is greater with
southward extent across the Chesapeake Bay area.  

Within the broader area of convection, isolated stronger storms are
ongoing -- the strongest of which are within a broken band from
Maryland across the Capitol region.  Locally damaging wind gusts
remain the primary risk with these storms, and those across the
remainder of WW 568 and 569 over the next few hours.
