A prolonged period of travel impacts – primarily from lake effect snow – appears increasingly likely in some areas in the early Friday morning through Saturday night time frame. However, considerable uncertainty remains in which areas the lake effect snow will impact and how much snow accumulation will be observed, so continue to check back for forecast updates.
Cold conditions will continue through the remainder of the week, but a gradual warming trend is expected into this weekend and early next week. No precipitation is expected through Thursday, but lake effect snow will affect many locations at the end of the week.
