SUMMARY...Multiple corridors of intensifying thunderstorm

development are expected this afternoon along and ahead of a cold

front. Adequate instability along with very strong deep-layer winds

will yield the potential for storms capable of damaging winds and

some hail. A tornado or two cannot be ruled out mainly across

southeast New York into southern New England. The severe risk will

diminish from west to east across the region by early/mid-evening.



The severe thunderstorm watch area is approximately along and 100

statute miles east and west of a line from 30 miles north of Laconia

NH to 35 miles east southeast of Allentown PA. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU4).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Severe Thunderstorm Watch means conditions are

favorable for severe thunderstorms in and close to the watch area.

Persons in these areas should be on the lookout for threatening

weather conditions and listen for later statements and possible

warnings. Severe thunderstorms can and occasionally do produce

tornadoes.

AVIATION...A few severe thunderstorms with hail surface and aloft to

1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A

few cumulonimbi with maximum tops to 450. Mean storm motion vector
