Areas affected...Portions of southeast New York and western New
England

Concerning...Severe Thunderstorm Watch 690...

Valid 010316Z - 010515Z

The severe weather threat for Severe Thunderstorm Watch 690
continues.

SUMMARY...The threat for isolated damaging wind gusts will continue
for the next few hours across WW690 -- especially over southeastern
portions of the watch.

DISCUSSION...While radar imagery indicates a general decrease in
storm intensity across much of WW690 over the last hour or so, the
thunderstorms moving from WW691 into southeastern portions of WW690
have remained somewhat stronger -- likely owing to relatively better
instability to the south. Given the strong low-level wind field
(e.g., > 50 knots near 1 km), isolated damaging wind gusts will
remain possible with the strongest storms as they move across
southeastern portions of WW690 (e.g., southeastern New York) over
the next several hours.
