What changed
A new cold-air system is moving across China this weekend, bringing rain from the Huanghuai region to the middle and lower Yangtze while sharply lowering temperatures farther north.
From October 31 to November 1:
- Parts of the Huanghuai, Jianghan, Jiangnan and southwestern regions face moderate to heavy rain, with locally torrential rain.
- Temperatures across and north of the middle and lower Yangtze are expected to fall by 4–8°C, and locally by more than 10°C.
- Harbin, Changchun and Shenyang are forecast to record their lowest temperatures since the start of autumn.
- Parts of Nyalam in Tibet have already recorded 63.3 millimetres of precipitation.
Why it matters
This is a sharp regional reset, not one uniform cold snap. In the northeast, afternoon highs in parts of Heilongjiang and most of Jilin will fall below 5°C today. In the south, some areas are still above 30°C before the cold air arrives.
That contrast will make the southward shift especially noticeable. Nanjing is forecast to reach 19°C and Hangzhou 18°C on November 3, with rain and cloud adding to the chill. The practical effect is a quick change from light clothing and warm afternoons to coats, wet roads and colder indoor spaces.
Heavy rain is also developing across the Huanghuai and Yangtze regions, while strong rain and snow continue near the Himalayas. Local rainfall totals and disruption levels remain uncertain, but the combination of falling temperatures and worsening weather means travel and outdoor work could become more difficult where downpours intensify. The southern spread of the cold air may also change as forecasts are updated.
