During the May Day holiday, cold air will bring rain to Guangdong.

During the May Day holiday, cold air will bring rain to Guangdong. It is expected that around May 1, a new round of strong cold air will go further south, bringing cold weather to the south of the Yangtze River. Affected by the cold air going south again, Guangdong will get cold again. During the May Day holiday, cold air will bring rain to Guangdong.

During the May Day holiday, cold air will bring rain to Guangdong. On April 24, Guangdong will continue to be affected by thunderstorms, but the rain is slightly "moderate" than on April 23. The meteorological department predicts that the shower weather in Guangzhou may last until the May Day holiday.

Compared with the rain in Guangdong the day before, it was much milder, and some water accumulation points in Guangzhou were "cleaning up the defects".

From the perspective of Guangdong Province, the reporter observed the data released by the meteorological department and found that as of the evening of April 24, the accumulated rainfall was selected as the "Top Ten in China" Guangdong Station by the Central Meteorological Observatory, which was less than that on April 23. In Guangzhou, although the urban area needs to issue rainstorm and thunderstorm warnings for two consecutive days, as of the evening of April 24th, the color of the highest warning for the whole day is only yellow, which is lower than the orange of the previous day.

In the second half of the afternoon of April 24, the rain stopped in Guangzhou, and sunshine, blue sky and white clouds were even visible in some periods.

On the afternoon of April 24th, Guangzhou was once sunny after the rainstorm, with sunshine, blue sky and white clouds in the sky.

The relatively mild rainfall made it possible for some urban areas where waterlogging occurred during the rainstorm raid the night before to "clean up the mess". On the afternoon of April 24, the reporter saw at Tianhe Park Station of Tianfu Road subway that was waterlogged on the night of April 23 that the staff of Guangzhou Urban Drainage Co., Ltd. were working on the spot, cleaning the blockage of the road outlet by hand or tool washing, so that the outlet could work normally when the rainstorm occurred again.

The rainy weather in Guangzhou may last until the May Day holiday.

The Guangdong Meteorological Observatory forecast on the evening of April 24th that there will be sunshine in some areas of Guangdong from April 25th to 27th, and there will be (light) fog in the morning and evening. Thunderstorms are frequent during the period, with local heavy rain or rainstorm accompanied by strong convective weather such as local short-term heavy precipitation, thunderstorms and strong winds of magnitude 7 or so, and small hail. The Guangzhou Meteorological Observatory predicted on the evening of April 24th that the urban area of Guangzhou will be mainly cloudy in the next three days, with thunderstorms accompanied by strong convective weather such as strong lightning, short-term heavy precipitation and short-term strong wind, and light fog in the morning and evening.

Combined with the forecast of Guangdong Meteorological Observatory and Guangzhou Meteorological Observatory on the evening of April 24, it is estimated that there will be moderate rain and partial heavy rain in Shaoguan and Qingyuan on April 25, and there will be (thunder) showers on cloudy days in some cities and counties along the coast of western Guangdong and the Pearl River Delta, and scattered (thunder) showers on cloudy days in other cities and counties in Guangdong.

It is estimated that the lowest temperature in the Pearl River Delta and most cities and counties in western Guangdong will be between 23 and 26℃ that morning, and the lowest temperature in other cities and counties in Guangdong will be between 20 and 23℃. Guangzhou is cloudy to cloudy with thunderstorms and light fog in the morning and evening, and the temperature is 24 ~ 3 1℃.

It is estimated that on April 26th, cities and counties in northern Shaoguan and northern Qingyuan will be cloudy to cloudy with heavy rain and partial heavy rain, while other cities and counties in Guangdong will have (thunder) showers and partial heavy rain on cloudy days. It is estimated that the lowest temperature in most cities and counties in Guangdong will be between 23℃ and 26℃ that morning. Guangzhou is cloudy to cloudy with thunderstorms and light fog in the morning, and the temperature is 24 ~ 3 1℃.

It is estimated that on April 27th, cities and counties in northern Guangdong and the northern Pearl River Delta will have moderate to heavy rain or heavy rain, while other cities and counties in Guangdong will have cloudy (thunderstorm) showers and partial heavy rain. It is estimated that the lowest temperature in northern Guangdong will be between 2 1 ~ 23℃ and that in other cities and counties in Guangdong will be between 23 ~ 26℃. Guangzhou is cloudy with thunderstorms on cloudy days, and the temperature is 24 ~ 30℃.

Combined with the seven-day forecast and ten-day trend forecast released by Guangzhou Meteorological Observatory on April 24, the shower weather in Guangzhou may last until the May Day holiday. Looking forward to April 28-29, the urban area will be mainly cloudy with occasional showers; On April 30, due to the unstable edge of subtropical high, the first day of May Day holiday was cloudy with thunderstorms; On May 1-2, the second and third days of the May Day holiday, there was a small to moderate rain precipitation process due to the influence of high altitude fluctuation, shear line and weak cold air.

The meteorological department of Guangdong Province reminded that it will be rainy (thunderstorm) in Guangdong in the next few days, and pay attention to prevent local strong convective weather and its secondary disasters.

Guangdong Erchao's forecast shows that with the accumulation of strong cold air masses in Mongolia Plateau and Siberia again, a new round of strong cold air has begun to infiltrate into the central and eastern regions of China quietly. Under the violent fluctuation of the westerly belt, it is expected that around May 1, a new round of strong cold air will go further south, bringing cold weather to the south of the Yangtze River.

At the same time, due to the strong airflow center of Leng Yun Group in Siberia, it is expected that cold air will pass through Nanling to Guangdong after May 2. By then, affected by the cold air going south again, Guangdong will get cold again.

It can be seen from the prediction of supercomputer that the new round of cold air has a wide range of influence. Under the violent oscillation of the westerly belt, the Leng Yun regiment accumulated in the middle and high latitudes will once again penetrate into the south of China, once again breaking the warmer weather in the south of the Yangtze River. At this point, under the continuous infiltration of cold air, many places in the south of the Yangtze River will once again usher in the cold weather in late spring.

The medium-term forecast of China Meteorological Observatory also shows that the temperature in China is expected to fluctuate greatly at the end of April and the May Day holiday due to the influence of two cold air streams. The first cold air is expected to be from April 25 to April 27, when the Jianghuai and Jiangnan areas will once again usher in a wide range of severe cooling weather. During the May Day holiday, affected by the second cold air southward, cities in South China such as Guangxi, Hainan, Fujian and Guangdong did not rule out the phenomenon of cooling down again.

In other words, a new round of cold air will not only go deep into the south of the Yangtze River, but also bring a wide range of cooling weather to Guangdong. Under the continuous "outbursts" of cold air, it is predicted that the temperature in Guangdong will become unstable again around May 1, and with the influx of a large number of warm and humid air masses over Guangdong, the rain will obviously increase, and cold air is likely to bring rain again. When cold air goes south on a large scale, it will be accompanied by rain, and Guangdong will once again usher in rainy and cold weather.

In other words, during the May Day holiday, cold air activities are still frequent, and the proverb "You haven't eaten May Zongzi, but you can't wear cold clothes" is likely to appear again. Under the abnormal climate pattern this year, there are indications that cold air will go south again. It is expected that Guangdong will get cold again around 1 in May. Everyone should pay attention to prevention and beware of colds!

During the May Day holiday, cold air will bring rain to Guangdong. Since yesterday (April 24), large-scale rainfall in the south of the Yellow River in China has gradually begun, with strong rainfall in Sichuan, Shaanxi, Chongqing, Henan and Hubei, and strong rainfall in some areas; Today, heavy rainfall will further move eastward and southward, and Jiangsu, Anhui, Zhejiang, Guangxi and Guangdong will be affected. There may be heavy rain in Jiangxi and Hunan.

Today, heavy rainfall in the south continues to "control the field". Local rainstorms in Jiangxi and Hunan, accompanied by strong convection.

Yesterday, the process of heavy rainfall in the south of the Yellow River officially began, with heavy rainfall in Henan, Sichuan and Chongqing, accompanied by strong convective weather in some areas. There were heavy rains in southwestern Shaanxi, southern Henan, northeastern Sichuan, Chongqing, eastern and southern Guizhou, Hubei, northern Hunan, southern Anhui, northwestern Jiangxi and northeastern Guangxi, and heavy rains in Nanyang, northern Chongqing, southeastern Hubei, Xiangyang, Jiujiang, Jiangxi and Guangxi.

The maximum hourly rainfall in the above areas is 30 ~ 98 mm; There are 8 ~ 10 thunderstorms and strong winds in parts of southern Chongqing, north-central Guizhou, southern Hubei, south-central Hunan, western Jiangxi and eastern Fujian. Hail occurred in central Guizhou and central Fujian.

Today and tomorrow, the heavy rainfall area will further move eastward and southward, with heavy rain and local rainstorm (100 ~180mm) in parts of southern Huanghuai, Jianghuai, Jiangnan and northern South China, accompanied by short-term heavy precipitation and strong convective weather such as thunderstorms or hail.

Specifically, today, there are small to medium snow or sleet in northeastern Inner Mongolia, eastern Tibet in northern Heilongjiang, and southern Qinghai. There are heavy rains in eastern Henan, northern and southern Anhui, Jiangsu, Shanghai, southeastern Guizhou, eastern and southern Hunan, Jiangxi, central and northern Zhejiang, western Fujian, northwestern Guangxi and northern Guangdong, among which there are heavy rains in central and northeastern Jiangxi and eastern Hunan (100 ~ 130mm).

Tomorrow, there will be light snow or sleet in northeastern Inner Mongolia, northern Heilongjiang, northern Tibet, southern Qinghai and northeast China. There are moderate to heavy rains in parts of southern Hunan, south-central Jiangxi, south-central Zhejiang, north-central Fujian, northwestern Guangxi and northern Guangdong, and local heavy rains (50-90 mm) in southern Jiangxi.

It is worth noting that due to the influence of strong vortex and low-level warm and humid airflow, rainfall in some parts of the south may be extreme. The public should pay attention to the forecast and early warning issued by the local meteorological department and be alert to the possible adverse effects and potential disasters caused by heavy rainfall. In addition, strong convective weather such as short-term heavy precipitation, thunderstorms or hail may occur in Guizhou, Hunan, Hubei, southern Henan, Jiangxi, Jiangsu and other places, and attention should be paid to prevention.

Cold air frequently disturbs sandstorms in the north, and the temperature fluctuates.

In terms of temperature, it is expected that cold air activity will remain active before the end of April. From today to the 27th, the northern part of China will be affected by cold air again, and the temperature in many places will drop by 4~8℃, especially in the central and western Inner Mongolia, northern Hebei, northwestern Shanxi and eastern Huanghuai. The cooling range can even reach above 10℃. Not only that, today and tomorrow, northwest China, north-central North China, southwest Northeast China and other places will also be hit by strong winds and dust, and some of the above areas will have sand blowing or floating dust weather.

However, before the arrival of cold air, most parts of the north can still have a warm period of 1 to 2 days. For example, in Beijing, the highest temperature may reach 29℃ today, and the feeling of early summer is sufficient, but by the 28th, the highest temperature in Beijing will drop to 17℃, with a cumulative drop of 12℃.

Not only in the north, but also in the south of China in the next few days. It is expected that after the 27th, cold air combined with rainfall will also bring significant cooling to the south. And looking forward to the later period, from April 28 to 30, there will be cold air moving eastward and southward to bring about cooling. Generally speaking, in the last week of April, the temperature rose first and then fell in many places, and the temperature fluctuated obviously in many places. The public in the above areas should pay attention to the approaching forecast, increase or decrease clothing in time, and beware of catching a cold.
