May Day felt more like Mother Nature yelling "mayday" as very cold air along with snow entered the state. The cold front still bisected the state by mid afternoon on Wednesday leaving the far eastern portions in the warm air. Temperatures soared well into the 80s while northwest Iowa was near freezing.
