Heavy snowfall in southern Finland in May is extraordinary nowadays - but was it more common a hundred years ago?

The weather in Finland is highly variable, but the mean temperature has risen by over 2°degC from the mid-nineteenth century to the present. The winter and spring months have especially warmed, though the large variability has been maintained. In addition, the snow season in Southern Finland is gradually shortening. Thus, heavy snowfalls in the spring are not as common as they used to be. In this study, two springtime heavy snowfall cases in Helsinki in May 1915 and May 1916 were investigated. The findings are compared to present (and predicted future) climate conditions.
