May Heats Up Across the Area

Very warm air squeezed out ahead of a frontal zone as it dropped southward and stalled near Interstate 90 overnight, and as the front began to lift northward as a warm front on Tuesday, the strong southwest winds and strong May sunshine aided in maximizing the heating potential across the area.
