If you wake up to flakes flying on Mother's Day morning in the Great Lakes, Ohio Valley and Interior Northeast, you just may not be dreaming. That's because stubborn spring cold will combine with a moisture laden storm system to drop temperatures just low enough for some wet, sloppy snowflakes.
Snow in May in this part of the nation is not unheard of, but it is rare. The last time Chicago recorded a trace of snow in May was 2004. In and around this region, measurable snow in May seems to occur about once every decade or two depending on how far north or south the location is.
