On April 29, the temperature in many places in the south will exceed 10℃, and there will be strong winds of magnitude 7 in some areas.

In the past two days, cold air has been affecting the northern region, especially yesterday (28th), under the influence of cold air, snowfall occurred in Beijing, Shanxi and other places. Now it is affecting the southern region. It is estimated that the temperature in many places in the south will drop by more than 10℃ in the next three days! At the same time, there will be strong winds of magnitude 7 or so in some areas, and the wind-cold effect is remarkable. Keep warm.

In many places in the south, the temperature will drop above 10℃, and some areas now have strong winds of about magnitude 7.

Cold air influence

Affected by cold air and precipitation, the temperature in southern North China, Huanghuai, Jianghan, Jianghuai, central and western Jiangnan, northern South China, southern Xinjiang basin and northwest China will drop by 4 ~ 8℃ from 08: 00 on the 28th to 08: 00 on the 30th. Among them, the temperature drop in southern Henan, northern Hubei and northern Hunan can reach more than 10℃! Some of the above areas will be accompanied by northerly winds of 4 ~ 5, with gusts of about 7. The wind-cold effect is obvious, and the body feels colder. Pay attention to the cold!

Cold air is more active recently. On the 26th, the temperature in Inner Mongolia, northwestern Shanxi and northern Hebei plummeted, and the local temperature drop in central Inner Mongolia exceeded 20℃. Yesterday, cold air continued to affect North China, Huanghuai, Jianghuai and other places, and the cooling rate in some areas also reached more than 10℃.

This cold air will continue to affect our country southward today, and from tomorrow, another cold air will further suppress the temperature. The Central Meteorological Observatory predicts that the temperature in southern North China, Huanghuai, Jianghan, Jianghuai, central and western Jiangnan, northern South China, southern Xinjiang basin and eastern Northwest China will drop by 4 ~ 8℃ from 08: 00 on the 28th to 08: 00 on the 30th. Among them, the cooling range in southern Henan, northern Hubei and northern Hunan can reach 10℃ or above. Some of the above areas will be accompanied by northerly winds of 4 ~ 5, with gusts of about 7.

May day weather

Under the continuous influence of cold air, the temperature in most parts of the north is mainly low before the May Day holiday. The highest temperature in Northeast China is less than 20℃, and the highest temperatures in Northwest China, North China and Huanghuai fluctuate around 20℃.

Most areas in the south will also experience the process from warm to cool, and the temperature will gradually turn lower than normal. Like Changsha and Nanchang, the highest temperature was above 25℃ yesterday, and it will drop below 20℃ around the 30th. From southwest to south China, the temperature drops from April 30th to May 1. The maximum temperature in many places may reach around 30℃ before cooling, and around 20℃ after cooling, and the cumulative cooling in many places exceeds 10℃. Seasonal cooling experience will be much cooler.

From May 1, the temperature in most parts of the north will enter the recovery channel, and the temperature in Xinjiang, Liaoning and North China Plain will rise rapidly. On May 3, the highest temperature in many places will rise to around 30℃, and some places will even hit a new high this year.

As far as precipitation is concerned:

deposit

The arrival of cold air also brought precipitation to many places in China, with snowfall in many places in the north and heavy rainfall in the south. Monitoring shows that there are scattered rainstorms in southern Shaanxi, eastern Sichuan, southern Chongqing, northern and eastern Guizhou, southern Hunan, southwestern Jiangxi and western Fujian, and local rainstorms in Ganzhou, Jiangxi and Chenzhou, Hunan (100 ~ 140mm, with the maximum hourly rainfall of 30 ~ 68mm).

Today, large-scale precipitation will continue. The Central Meteorological Observatory predicts that there will be light snow or sleet in parts of northeastern Inner Mongolia, Qinghai, northern Tibet and southern Xinjiang basin. There are moderate to heavy rains in parts of Jianghuai, Jianghan, Jiangnan and northern South China, among which there are heavy rains (50-90 mm) in parts of southern Anhui, southeastern Hubei, northern Hunan, northwestern Jiangxi, western Zhejiang and northwestern Guangxi.

From April 29th to May 1 day, there were moderate to moderate rains in the eastern part of southwest China, south of the Yangtze River and south China, and there were heavy rains and local rainstorms in some areas. The public should pay attention to the approaching forecast and guard against the adverse effects caused by local heavy rainfall and strong convective weather.

Main weather processes:

On 28-29, affected by cold air, the temperature in southern North China, Huanghuai, Jianghan, Jianghuai, central and western Jiangnan, northern South China, southern Xinjiang basin and northwest China will drop by 4-8℃, and the local temperature will drop by more than 10℃. On the 28th, there were moderate to heavy rains in Jianghan, Jiangnan and western South China, among which there were heavy rains in northern Hunan, southeastern Hubei, northwestern Jiangxi, southern Anhui, western Zhejiang and northwestern Guangxi.

On 29-30, there were small to moderate rains in the eastern part of southwest China, Jiangnan and South China, heavy rains in some areas and local heavy rains; In addition, on May 1-3, there will be obvious wind and rain weather in the South China Sea and the coastal areas of South China, and there will be heavy rain in Hainan Island, the coastal areas of Guangdong Province and the islands of Taiwan Province Province.

On May 2-3, affected by cold air, the temperature in eastern and northeastern Inner Mongolia will drop by 4 ~ 8℃, and the local temperature will be above 10℃. In addition, there will be a strong cold air process in the northern region around May 5.
