The rain and snow will gradually cover the eastern part of Southwest China, the eastern part of Northwest China, North China, Huanghuai, Jianghan, Jianghuai and other places, with large scope, strong intensity and long duration, and the temperature will also drop sharply. However, before the arrival of rain and snow, the temperature will continue to rise, and the middle and lower reaches of the Yangtze River will usher in abnormal warm weather, feeling the spring in advance.
Since the night of the 4th, the first round of large-scale rain and snow weather process in 2020 has begun, which may become the strongest rain and snow weather process since this winter. Monitoring shows that yesterday, there was light to moderate snow in southern Qinghai, central Tibet and Northern Shaanxi, heavy snow in Qinghai and snowstorm in Nyalam, Tibet (15mm); snow, rain or rain to snow in some areas of Southeastern Gansu, Southern Ningxia, central Shaanxi, southern Shanxi and northwestern Henan was 2-8mm, and local snow in northwestern Henan was 10-14mm; Moderate to heavy rain occurred in some areas of central Yunnan, western Guizhou and northern Chongqing, and local rainstorms (50-68mm) occurred in Lincang and Pu'er of Yunnan.
The Central Meteorological Observatory predicts that today, there will be light to moderate snow or sleet in the eastern part of the Qinghai Tibet Plateau, the eastern part of Northwest China, most of North China, the western and southern part of Liaoning, the western and northern part of Henan, and some parts of eastern Tibet, northeastern Shaanxi, central and southern Shanxi, Northern Henan, and southwestern Hebei, with heavy snow and local Blizzard (10-12 mm). Light to moderate rain occurred in southeastern Tibet, Eastern and southern parts of Southwest China, most of Huanghuai River, Jianghuai River and northern part of Jiangnan, among which heavy rain occurred in Western and southern Yunnan, northern Chongqing and eastern Anhui.
Tomorrow, there will be light to moderate snow or sleet in most parts of Northeast China, the east of Northwest China, the West and south of North China, and the west of Huanghuai river. Among them, there will be heavy snow or blizzard (10-18 mm) in some parts of Western Tibet, southwest Heilongjiang, North central Shaanxi, and South Shanxi. There are moderate to heavy rain and local rainstorm (50-60mm) in the East and south of Huanghuai River, most of Jianghuai River, most of Jianghan River, the north and west of Jiangnan River, and the east of Southwest China.
The day after tomorrow, there will be light to moderate snow or sleet in some areas of southeast Heilongjiang, central and Eastern Jilin, western mountainous areas of Southern Xinjiang, northern and Western Tibet, eastern part of Northwest China, central and southern part of North China, and most of the Huanghuai river. Among them, there will be heavy snow or blizzard (10-15mm) in some areas of Western Tibet, southern part of North China, and eastern part of the Huanghuai river. Light rain occurs in most of the Yangtze and Huaihe River, the north and west of Jianghan, the north and southwest of Jiangnan, and the east of Southwest China.
The arrival of rain, snow and cold air will also make the temperature fluctuate violently. The eastern part of Northwest China, North China, south of Northeast China and Jiangnan will gradually meet the temperature drop. Among them, the temperature drop in northern China was mainly concentrated on the 5th and 6th, while that in North China and Huanghuai was 4-8 ℃ and that in local areas was more than 10 ℃. At that time, the temperature in the above areas will drop to a low level again, and the body will feel cold and humid, and the maximum temperature 0 ℃ line will gradually press south to the south of Huanghuai river. For example, the highest temperature in Zhengzhou was still around 11 ℃ on the 4th, only 2 ℃ today, and it will even drop to minus 1 ℃ on the 8th. This will be the first time that the highest temperature in Zhengzhou will fall below freezing point this winter.
In the middle and lower reaches of the Yangtze River, the temperature will further rise before the arrival of cold air and precipitation. On June 7, the temperature in the above areas will rise to the highest point, with the highest temperature reaching about 20 ℃ and the lowest about 10 ℃. Many places will feel the spring like warmth ahead of time. For example, in Shanghai, Hangzhou and Nanchang, the highest temperature may exceed 20 ℃, which is 10 ℃ higher than the average level in the same period of the year. This kind of temperature is very rare in January and may challenge the record of extreme value in early January. However, after the warm, the above areas will also face a sudden drop in temperature, and the change between cold and warm is very rapid. Remind the public to pay more attention to the weather forecast, timely adjust their clothes according to the temperature change, to avoid catching a cold.
