Strong to Severe Thunderstorms Thursday

An unseasonably strong low pressure system will cross the Great Lakes Thursday, and will likely produce strong wind gusts across Western NY, the Finger Lakes, and the eastern Lake Ontario region. Peak wind gusts may reach the 45 to 55 mph range, with some isolated wind damage and power outages possible.

A cold front crossing the area on Thursday will cause strong to severe thunderstorms to develop during the late morning and afternoon hours. The primary threat is strong winds with the thunderstorms. The potential for strong to severe thunderstorms increases from west to east, with the greatest chances east of the Genesee Valley.
