昨日16日午後は天気が不安定で雹も降る：2023年4月17日（月）

　昨日16日午後４時頃に，京都市北区上賀茂の大学では珍しく大粒の雹（ひょう）が降ってきた。直径１cm程度の大粒（右写真）のものでした。雹が金属に当たり，カキーンと鉄琴の鳴らす音のように響き渡りました。雨が降っていないのに，雷鳴が響き渡りました。青天の霹靂でしょうか？

Yesterday, April 16th, in the afternoon, the weather was unstable and hail fell：April 17th(Monday)

Yesterday, around 4:00 PM on the 16th, unusually large hailstones fell at a university in Kamigamo, Kita-ku, Kyoto City. The hailstones were about 1 cm in diameter (as seen in the photo on the right). When the hailstones hit metal, they made a ringing sound reminiscent of a xylophone. Despite there being no rain, thunder could be heard. Would this be what they call a "bolt from the blue" in Japanese?
