Severe thunderstorms and tornadoes are a real threat from April through June, while winter brings heavy lake-effect snow, ice storms, and dangerously low wind chill. Flat terrain means high crosswinds can affect vehicle stability year-round, especially for taller vehicles. Spring flooding can also close highway underpasses and low-lying road segments.
