Too little, too late
Snow-covered area was 203 percent of average for April, ranking second highest in the 24-year satellite record. Despite a snowy April, snow cover days were below average because of a widespread slow start to the snow season. States in the north reported below-average snow water equivalent, while the opposite was true for states in the south.
