Areas affected...Portions of eastern New York...northeast
Pennsylvania...and western New England

Concerning...Severe Thunderstorm Watch 690...

Valid 010021Z - 010115Z

The severe weather threat for Severe Thunderstorm Watch 690
continues.

SUMMARY...The potential for damaging wind gusts continues across
Severe Thunderstorm Watch 690.

DISCUSSION...Latest radar imagery shows a north-to-south line of
gusty thunderstorms extending across western portions of Severe
Thunderstorm Watch 690. While instability is very weak over the area
(250 J/kg or less based on RAP Mesoanalysis and ALB 00Z radiosonde),
a very strong low-level wind field (50 knots at 0.5 km per ALB
radiosonde) will continue to foster periodic localized damaging wind
gusts over the next several hours even in the absence of lightning.
