Cctv newsAccording to China Weather Network, it is predicted that the lowest temperature in the middle and lower reaches of the Yangtze River in Jiangsu, Zhejiang and Shanghai will hit a new low in the second half of this year tomorrow (24th-25th). In the northern region, in the next three days, there will be a weak precipitation process from west to east in the eastern part of northwest China, central and western Inner Mongolia, north China and northeast China, while the rain will weaken in the southwest region where it continues to be rainy. Due to the weak cold air and the increased humidity of precipitation air, there will be fog in North China, Huanghuai and other places from the 24th.
The rain in southwest China weakened, and it began to rain in northwest China and north China.
Yesterday, precipitation in China was mainly concentrated in the southwest. Monitoring showed that heavy rain occurred in some parts of southwest Yunnan, and heavy rain fell in Pu ‘er, Xishuangbanna and other places.
Starting today, the precipitation in southwest China will further weaken, but there will be a new round of precipitation in the eastern part of northwest China and North China. The Central Meteorological Observatory predicts that there will be small to moderate rains in the eastern part of northwest China, central Inner Mongolia and most parts of southwest China from 08: 00 on the 24th to 08: 00 on the 25th. Among them, there are heavy rains in parts of southern Yunnan and southeastern Tibet, and there are heavy rains in the local area. There are small to medium snow or sleet in central and southern Qinghai, northern and central and eastern Tibet, and heavy snow in some areas.
From 08: 00 on the 25 th to 08: 00 on the 26 th, there were small to moderate rains or showers in northern Xinjiang, central Inner Mongolia, central and western North China, most of Shaanxi, most of Southwest China, and southeastern Tibet; There are small to medium snow or sleet in eastern and southern Qinghai, north-central Tibet and northern Sichuan Plateau, among which there is heavy snow in parts of southern Qinghai and northern Tibet. There are 4 ~ 6 winds in parts of northern Xinjiang and central and western Inner Mongolia.
Recently, the southwest region has been in the midst of heavy rain, which has a great impact on agriculture. It is necessary to pay special attention to the harvested crops to prevent mildew. At the same time, it is also necessary to seize the rainy season, sow wheat and rape in time, and apply sufficient base fertilizer to ensure that the seedlings are strong.
In most of the central and eastern regions, especially in Jianghuai, Jiangnan and South China, it will be mainly sunny this week, and the public can seize the fine weather to travel or dry.
The temperature in the middle and lower reaches of the Yangtze River is lower, and the Huanghuai fog in North China is diffuse.
Yesterday, cold air affected Huanghuai and Jianghuai areas, and the temperature dropped significantly in northern Jiangsu, Anhui, southeastern Shanxi and western Henan. At 14 o’clock, the temperature dropped by 4-6℃ compared with the same time the day before yesterday, and the local temperature dropped by 7-8℃. The provincial capital cities Hefei and Nanjing all dropped by 4℃, and the temperature was less than 20℃ at 14 o’clock. However, after the cold air, the temperature in northeastern Inner Mongolia, western Heilongjiang, northern Qinghai, northwestern Sichuan and other places has obvious warming, with an increase of 4-8℃.
Today and tomorrow, cold air will go south to the middle and lower reaches of the Yangtze River. Due to the recent lack of precipitation and clear sky in the eastern region, the temperature will drop obviously in the morning and evening. Compared with the highest temperature, this cold air has a greater impact on the lowest temperature. This morning, the lowest temperatures in Nanjing, Shanghai and Hangzhou hit new lows in the second half of this year. Tomorrow morning, the lowest temperature in the provincial capital city of Hangzhou (10℃) will continue to hit a new low in the second half of this year.
Other areas in the south, without the disturbance of precipitation, will be mainly sunny and warm from 26 to 28, which is suitable for outdoor activities.
In the northern region, today, a new cold air began to affect the central and eastern parts of the northwest region, especially in northern Qinghai and central Gansu, where the single-day drop could reach 4-8 C, and the local maximum temperature might drop to 5 C. Tomorrow, the cold air will be transferred to the area from North China to Jianghan, with a drop of more than 3℃ in many places. The highest temperature in North China will drop below the average again, but the cold air will pass by in a hurry, and the temperature will return to normal after a short fluctuation.
The cold air force is weak, and the rainfall increases the air humidity. Since the 24th, the atmospheric diffusion conditions in the central and southern parts of North China and Huanghuai have deteriorated, with heavy fog in some areas in the morning and dense fog with visibility less than 500 meters in the local area. Low visibility weather has a negative impact on driving, so the public should also pay attention to safe driving, keep a safe distance between cars and slow down.
The next obvious cold air will wait until the 25th. It is expected that the cold air will take the lead in invading Xinjiang from 25th to 26th, and it will affect the central and eastern regions after 28th. The strength of this cold air will be relatively stronger. The temperature will drop by 4-6℃ in the south, 4-8℃ in the north, and 10-12℃ in some parts. There will be northerly winds of 4-6 in northern Jiangnan and most parts of the north.
