Hail in the summer season, Vantaa

The cloud I saw in the dark, from which I wondered what it was, rained when I went to the shops, so the time was not accurate, but when I came out the snow grains on the ground did not start to melt and hardened during the evening and are still intact at night. They were the largest I saw, almost about 1 cm in diameter, tense-shaped, like a space capsule returning to the atmosphere: conical, with the wider end curvedly crumbly than the cell formations of the mammatus cloud. The most special sight I have come across even during the years of the RaPu project. At least in front of Vantaa's Jumbo and a couple of hundred meters away, I don't know how wide the area is. As the nail crumbled, no ice was broken inside them, but the crystal structure of needle-like interconnected crystals extending longitudinally from the wide base of the cone to the narrow tip. If there had been a close-up lens, if anyone has one, they should still be found in the morning and on the railings.

En itse havainnut raesadetta. Ilmeisesti ei ihan Helsingissä rannan tuntumassa tullut. Sen sijaan kiinnitin illalla sekä seuraavana aaamuna (pienessä määrin jopa vielä keskiviikkoaamuna), että jotain lumirakeen tapaisia oli satanut, sillä paikoissa, jossa maa oli jäässä, jään pintaan oli jäänyt kiinni valkeita lumipalleroita.

Julmetun kokoisia lumirakeita (graupeleita).
