DISCUSSION: Over the course of the past 48 hours, a weak pulse of energy moved through parts of far northern Europe.  As this energy progressed through areas across far northern Europe, this helped to destabilize the ambient environment for deep convective storms.  As shown in the video attached above, there a period of large hail which impacted the city of Vantaa, Finland on the afternoon of 21 April.  Of particular interest was the fact that according to some reliable sources, hail diameters were measured at between 2 and 3 cm.  It is also worth noting that for hail stones to grow to such diameters, the hail stones much remain suspended in the cloud for a sufficient amount of time.  Thus, allowing the hail stones to accumulate ice on the exterior of the growing hail stone.  This is the process by which hail stones grow in effectively all cases before they are no longer supported by the given strength of a given updraft which is when they fall out of the cloud and plummet to the ground.
