Today is the coldest day in Shanghai in recent times, with temperatures ranging from 3 to 7 degrees throughout the day. The northwest wind increases to 4-5 gusts of 6, and under the wind chill effect, it feels even colder, so everyone should wear more. Fortunately, the north wind also blew away the haze, and the air quality improved this afternoon. The "timeliness" of this wave of cold air is very short, and it will be cold until Thursday morning, with a minimum temperature of about 1 degree in the city and minus 3 degrees to minus 5 degrees in the suburbs. It started to warm up during the day on Thursday.
During this year's "March Nine" period, although there was the influence of cold air from time to time, the overall impact was northerly and weak. After the temporary influence of cold air, the temperature in most parts of the country rose, and around the 14th, the maximum temperature in many places in the middle and lower reaches of the Yangtze River will break through 20 degrees, which is as warm as March all year round. In the next ten days, the temperature in Shanghai will show a trend of "short-term drop-rise-slight drop-and then rise". From Thursday onwards, the temperature will go out of a wave of "small sunny lines," and the maximum temperature on Sunday will even exceed 17 degrees; at the beginning of next week, under the influence of the spread of cold air, the temperature will drop, but it will still be only a "small episode," and it will rebound to 17 degrees again in the middle of next week! This is really not like the temperature of "Sanjiu," and you must know that the maximum temperature of "Sanjiu" in Shanghai should be in the early 10s of the year.
Although the cold air is frequent this week, the temperature on the mainland is still mainly high, including tomorrow (January 11) to the 14th, the temperature in the eastern part of the northwest region, Huanghuai and the middle and lower reaches of the Yangtze River will reach the high point this year, and the maximum temperature in the middle and lower reaches of the Yangtze River is expected to exceed 20 °C. In terms of precipitation, there will be a short period of snowfall in Inner Mongolia and Northeast China today and tomorrow, and rain in Guangxi, Guizhou and other places throughout this week.
From tomorrow, the temperature in the middle and lower reaches of the Yangtze River and other places will gradually reach high points, and many places will be as warm as March to April all year round
During the day yesterday, due to the northward influence of cold air, southern Jiangsu and Anhui, Zhejiang, eastern Hunan and other places showed a large area of warming under the sun, and the increase in many places exceeded 10 °C.
With the rapid movement of cold air to the south, the cooling range of the mainland is relatively wide today, and the temperature from the Yellow River Basin to the northern part of the Yangtze River is generally cooled, and the drop in some areas can reach 4~8 °C. In addition, tomorrow and the day after tomorrow and from the 13th to the 14th, there will be two waves of cold air in turn, and the temperature in the central and eastern parts will fluctuate.
However, after a short period of cooling, it will heat up rapidly as the cold air moves away, and the temperature will generally be on the high side. For the eastern part of Northwest China, Huanghuai and the middle and lower reaches of the Yangtze River, the temperature will reach the high point of this year from tomorrow to the 14th, and the maximum temperature will be significantly higher, and many places will be 10 °C or more, when the maximum temperature in some areas of Gansu, Shaanxi, Henan, Shandong and other places will reach more than 10 °C, and the maximum temperature in the middle and lower reaches of the Yangtze River may exceed 20 °C.
After the temperature rises, Gansu, Ningxia, Shaanxi, Hubei, Henan, Anhui and other places will experience the warmth of March and April in the coldest season. For example, Hefei was 17 °C for three consecutive days from the 12th to the 14th, the highest temperature in Wuhan was 20 °C on the 13th, and Changsha was 21 °C on the 15th, all of which were rare local warms in mid-January.
Rainy rain in Guangxi, Guizhou and other places will run through this week, and northern Xinjiang still needs to be vigilant against heavy snowfall
In terms of precipitation, the weather pattern of scarce rain and snow will remain in most parts of the north in the next few days, with continuous snowfall in northern Xinjiang and short-term snowfall in northeast and Inner Mongolia. The most rainy areas in the south are mainly concentrated in Guangxi, Guizhou and other places, and the rainy weather will continue throughout this week.
Specifically, there is light to moderate snow or sleet in parts of eastern Inner Mongolia, central and northern Heilongjiang, northern Xinjiang and other places today, among them, Tacheng and Altay areas in northern Xinjiang have heavy to heavy snowfall, and local heavy snowfall (20~25 mm). There was light to moderate rain in parts of the southeastern Sichuan Basin, western Chongqing, Guizhou, eastern Yunnan, Guangxi, southwestern Hunan, Hainan Island, and eastern Taiwan Island.
Tomorrow, there will be light to moderate snow or sleet in parts of northeast Inner Mongolia, most of Heilongjiang, eastern Jilin, northern Xinjiang, and southern Sichuan Plateau, among them, Tacheng, Altay and Ili River valleys in northern Xinjiang will have heavy to heavy snow (10~18 mm). There was light rain in parts of central and southern Guizhou, eastern Yunnan, Guangxi, southwestern Hunan, and central Hainan Island.
Meteorological experts reminded that in the coming period, rainy weather in Guangxi, Yunnan, Guizhou and other places will continue to be online, and the public needs to pay attention to the impact of slippery roads and low visibility on traffic when going out.
