Not too hard. Global warming means less snow pack in the mountains. Its melting feeds the Great Lakes. Think of it as delayed rainfall.
(OTOH the Great Lakes also have a cyclic nature that is not tied to AGW.)
(BTW in our part of the world-PNW, the mountain snowpack is 40% above average, threatening serious flooding later in May.)
