The worst of the wind will target areas around lakes Erie and Ontario, where gusts to 60 mph are possible later Thursday night into Friday midday.
The winds will create very rough conditions on the lakes. Flooding is possible on the northern and eastern ends of lakes Erie and Ontario, including Buffalo, N.Y.
Strong winds gusts, most ranging between 40 and 50 mph, will reach across the Ohio Valley, the central Appalachians and New England. However, gusts in these areas can be locally higher, especially in open areas, between buildings and gaps in the mountains and over the ridges.
Winds will increase over the Ohio Valley and Great Lakes during the day Thursday then over the central and northern Appalachians Thursday night.
Winds are most likely to cause flight delays and restrictions on bridges Friday morning around Philadelphia and New York City.
In New England, Quebec, New Brunswick and Nova Scotia, the worst of the wind will be during the day Friday.
