Foreword: Tomorrow's weather forecast on the 17th, a new round of cold wave and cold air is coming, and snow will cool down. Let's see what the weather looks like.
It is expected that from the evening of the 15th to the morning of the 17th, a strong cold wave and cold air will sweep across the south, and there will be a sharp cooling in Jiangnan, South China and other places. The temperature in Shanghai, Zhejiang, Fujian, southern Jiangxi, Guizhou, Guangdong, Guangxi and other places will generally drop by 12-16, of which some areas in southern Zhejiang and southeastern Guangxi can drop by 16-20.
The temperature will hit a new low in a large area] In the next few days, the cold air from north to south will continue**, and the temperature in most parts of China will continue to drop, turning sharply low in a large area, and may continue to hit a new low since the second half of this year.
Maximum temperature forecast: 17th, Harbin and Changchun -19, Shenyang -14, Nanjing 0, Fuzhou and Nanning 11.
Minimum temperature forecast: on the morning of the 17th, Beijing -16, Taiyuan -20, Changchun, Shenyang -24, Nanjing -6, Jinan -15, Fuzhou, Nanning -8.
In addition, when the cold air cools down, the wind also increases, and the wind chill effect causes the perceived temperature to be lower than the actual temperature, which can aggravate the cold.
What will happen to the precipitation from December 17th to tomorrow 18th?Snowfall and rainfall are mainly distributed in **?
Tomorrow, December 17, after a strong cold wave and cold air invaded the south on a large scale, the warm and humid air flow was "scared to the point of urine" by the cold air. The warm and humid airflow weakened, the water vapor conditions deteriorated, and the snowfall in most parts of the north stopped clearing. However, due to the replenishment of cold air, there is still snowfall in some areas of Xinjiang, Qinghai and other places in the northwest. At the same time, cold air and warm and humid airflows continue to converge in the Yangtze River basin, and the snowfall in the south has expanded, and pure snow may be pushed south as far as possible to the west of central Hunan.
Light to moderate snow or sleet occurred in parts of the western and southern mountainous areas of the Southern Xinjiang Basin, southeastern Qinghai, southern Shaanxi, northern Sichuan Basin, central and southern Hubei, eastern Chongqing, central and eastern Guizhou, northern and western Hunan, northern Jiangxi, southern Zhejiang, northern Fujian, northeastern Guangxi, northern Sichuan Plateau, northern and eastern Sichuan.
In terms of rainfall, the range of rainy weather in the south has also narrowed due to the weakening of warm and humid airflows. The rainfall was mainly concentrated in the south of the Yangtze River and the northern part of South China, and the intensity was mainly scattered light rain.
There was light rain in parts of the northern Sichuan Basin, central and eastern Hunan, most of Jiangxi, most of Fujian, central and eastern Guangxi, northwestern Guangxi, eastern Hainan Island, most of the islands of Taiwan Province, and southeastern China.
On December 18, that is, the day after tomorrow, the southwest warm and humid airflow strengthened again, and the cold air continued to penetrate southward to replenish. The two continued to compete fiercely, and snowfall in the Yangtze River basin developed again, and the snowfall could reach as far as northern Jiangsu and northern Anhui. The precipitation phase in the south is still more complicated, especially in Guizhou and western Hunan, where freezing rain may occur.
There is light to moderate snow or sleet in parts of southeastern Qinghai, southern Gansu, southeastern Henan, central and southern Anhui, northern and western Jiangsu, eastern Hubei, southeastern Chongqing, central and eastern Guizhou, western Hunan, northern Jiangxi, northwest Zhejiang, northeastern Guangxi, northern Sichuan Plateau, and eastern **.
In terms of rainfall, the warm and humid airflow strengthened northward, and the rainfall range advanced northward. The eastern part of Jianghuai will also join the rainy group chat. Jiangnan and South China will continue to be cloudy and rainy, and the rainy weather in some areas may remain **1-2 days, which is unbearable.
There was light rain in parts of the northern Sichuan Basin, central and eastern Hunan, most of Jiangxi, most of Fujian, central and eastern Guangxi, northwestern Guangxi, eastern Hainan Island, most of the islands of Taiwan Province, and southeastern China.
