This weekend, lake effect cooling will affect the Chicago area, bringing colder temperatures and higher wind speeds. Recent weather reports anticipate a cold air mass moving over Lake Michigan, causing a noticeable drop in temperatures, with daytime highs only reaching 50 degrees Fahrenheit (approximately 13 degrees Celsius). This weather phenomenon is typical for this time of year, as cold air interacts with the relatively warmer waters of Lake Michigan, resulting in localized cooling and gusty winds, particularly near the lakefront.
