Northern Hemisphere cold outbreaks are increasing as October nears its close, from East Asia to North America.

In Japan, the Wakkanai Local Meteorological Office issued a low-temperature advisory Friday (Oct 24) as Arctic air continues to dominate Hokkaidō. Highs again stalled in the single digits, with widespread frost and lingering snow across the north.

Across China, the National Meteorological Center’s 06:00 bulletin confirms ongoing snow in eastern Qinghai and “cold-air impacts” pushing deep through Inner Mongolia and into the northeast. Sub-freezing mornings and below-normal daytime highs now stretch across the northern tier.

In India’s western Himalaya, temperatures again slipped below zero overnight in Himachal Pradesh. Tabo registered -0.7C (31F), with the local meteorological department warning of continued snow in Lahaul-Spiti, Kinnaur, and Chamba districts.

Meanwhile, the United States is seeing its first widespread taste of winter. Cincinnati logged a morning low of 37F (3C), the city’s coldest air since spring, as the NWS issued freeze warnings across the Ohio Valley. Philadelphia also reported its coldest night of the season so far as frost advisories expanded through the Mid-Atlantic.

From Asia to the Americas, October’s final week across the Northern Hemisphere is delivering a distinctly wintry turn — a setup in part governed by a weak start to the ‘polar vortex’ and impressive snow cover across Siberia and Mongolia.
