Warm moist tropical air from the Gulf drives the Midwest’s humid summer climate

Evidence

The tropical Gulf or tropical Atlantic air mass is warm and moist, bringing the typical muggy summer days of the eastern and midwestern states as it moves north in summer. By contrast, a deep sea smell and a cold and blustering wind, followed by rain or snow, usually comes down from the northern Atlantic to the northeast states in the form of the polar Atlantic air mass. — Vinson Brown, Reading the Woods, 87
