Areas affected...Interior southern New England...New Hampshire and
western/northern Maine

Concerning...Severe Thunderstorm Watch 354...355...

Valid 191858Z - 192100Z

The severe weather threat for Severe Thunderstorm Watch 354, 355
continues.

SUMMARY...Thunderstorms accompanied by locally heavy rain, frequent
lightning and potentially damaging wind gusts will overspread the
region through 4-6 PM EDT.

DISCUSSION...Insolation has warmed surface temperatures through the
lower/middle 80s within a narrow pre-frontal corridor across
interior southern New England through the higher terrain of
western/northern Maine.  This appears to be contributing to mixed
layer CAPE on the order of 1000-2000 J/kg, and likely will provide
the focus for the most vigorous thunderstorm development through
20-22Z.  This will be accompanied by the risk for potentially
damaging surface gusts, particularly from near/northwest of
Worcester through areas near/west and north of Manchester/Concord
NH, where it appears that ambient southerly 850 mb flow has
increased in excess of 40 kt.
