Rain season
Chicago gets rain through the year, with spring (April–May) the wettest season and summer producing heavy convective thunderstorms. Lake Michigan moderates temperature but also drives lake-effect precipitation in autumn and winter, when snow can accumulate rapidly and unpredictably. The wind genuinely amplifies the impact of wet weather — rain feels harder here than the numbers suggest.
