Weather Talk: April snow is unsettling, but it isn’t unusual
Snow in mid-April always seems like more of an anomaly than it actually is. Fargo-Moorhead averages 3 inches of snow for April.
Some years, this is that last little bit before it all melts. Other years, this is that late-spring snow that falls long after the winter snow has melted. Some years, April snowfall is above average. Some years, there is no snow in April. April is just that way. But April snow is not unusual, even if it is unsettling.
Snow in May is much more of an anomaly. Snow will fall somewhere in North Dakota or northern Minnesota every few years. But snow in May tends to be highly localized, covering a very small area where conditions are just barely cold enough. The relative rarity of May snowfall at any one location relegates average May snow to the trace category.
