Russia, broadly, has opened June cold.

In the south, Primorsko-Akhtarsk, on the Sea of Azov, set a new daily minimum record on June 2. The temperature fell to 10.3C (50.5F), beating the previous June 2 record of 11.1C (52F), set in 1951.

It followed a sharp late-May chill across Krasnodar Krai.

On May 31, record lows were reported in Sochi, Tuapse, Primorsko-Akhtarsk and Krasnaya Polyana. Sochi fell to 8.6C (47.5F), beating a mark from 1904. Tuapse dropped to 9.6C (49.3F), undercutting its 1956 record. Krasnaya Polyana fell to 3C (37.4F).

Russian reports blamed prolonged rain, heavy cloud and, crucially, an intrusion of Arctic air. Snow fell in the mountains. Heavy rain hit the coast. The cold carried into June and is threatening to break further records along Russia's southern edge.

Farther east, Siberia has also slipped back toward winter.

Frost warnings stretched from Omsk and Novosibirsk to Kemerovo, Altai Krai and Orenburg. Overnight lows were forecast to reach -5C (23F), cold enough to devastate crops, gardens and spring vegetation.

In Kemerovo Oblast, daytime temperatures struggled near 4C (39.2F). Snow was reported in Kuzbass. Tuva faced wet snow, thunderstorms, hail and damaging winds. Buryatia saw mountain wet snow and a severe temperature drop. Around Irkutsk and Lake Baikal, snow remained in higher terrain, with more frosts expected.

Heating systems have been turned back on across swaths of Siberia.
