Areas affected...the Mid-Atlantic into portions of the Northeast

Concerning...Severe Thunderstorm Watch 561...

Valid 071957Z - 072130Z

The severe weather threat for Severe Thunderstorm Watch 561
continues.

SUMMARY...The severe weather threat continues in watch 561. Damaging
winds and large hail are the primary threats.

DISCUSSION...Numerous storms and storm clusters have developed from
northern Virginia northeastward to southern Vermont and New
Hampshire. These storms have produced numerous wind damage reports
up to this point with a measured severe wind gust of 59 mph in
Delaware and 63 mph in Massachusetts. There have been no severe hail
reports up to this point which is likely due to the hot
lower-tropospheric airmass. However, some MESH cores have suggested
hail to near 1 inch, so would still anticipate at least an isolated
severe hail threat to continue into the evening. The greatest severe
weather threat will likely be in southeast New York and New Jersey
for the next 1 to 2 hours where instability and storm coverage is
greatest, and mid-level winds have increased to 45 to 50 knots (per
DOX/DIX/OKX VWP).
