Will snow and ice come again? , the highest temperature in Shanghai plummets by 11℃ in 24 hours starting tomorrow, and a cold wave is coming.
The cold wave is coming, and Shanghai will feel like winter will return from early summer in seconds. The Shanghai Central Meteorological Observatory predicts that the maximum temperature will drop in half within 24 hours from tomorrow, from 22℃ to 11℃.
These days, Shanghai seems to be "rotating" through the four seasons. Today, the highest temperature in Shanghai is fixed at 19.3℃, which feels like spring. The temperature will continue to rise tomorrow, reaching a maximum of 22°C to 23°C. It seems to be fast forwarding to summer, and there will be fog in some areas and the Yangtze River Estuary area at night.
The Central Meteorological Observatory said that such warmth is relatively rare. Nationally, the highest temperature in the area from Huanghuai to the middle and lower reaches of the Yangtze River is even comparable to April levels all year round, and the 20°C line will also expand. The highest temperature in Hefei, Nanjing and other cities will reach 20°C for the first time this year.
However, affected by the cold wave, the temperature in Shanghai quickly returned to normal. On February 15, the highest temperature in Shanghai was only 11°C. On the 16th, Shanghai ushered in the lowest temperature of this cold wave, with the lowest temperature being 4°C in the urban area and 1°C to 3°C in the suburbs.
In terms of wind power, from the morning of the 15th, the northerly wind in Shanghai began to increase. On the 15th, the maximum gust wind on land was level 6 to level 7, and the coastal areas along the river and the Yangtze River Estuary area were level 7 to level 8. The Yangshan Port area and the coastal sea surface of Shanghai city Level 8 and level 9. The wind weakened on the morning of the 16th.
In terms of precipitation, there will be weak precipitation in Shanghai tonight due to the influence of the shortwave trough. It will be cloudy and overcast tomorrow, but the humidity will be high at night. There will be fog in some areas and the Yangtze River Estuary, and local visibility will be less than 200 meters. On the 15th, there were cloudy showers or thunderstorms in Shanghai and the Yangtze River Delta region, with mainly light to moderate rainfall.
In early February, our country experienced the strongest rain, snow and freezing weather since 2009. Severe rain, snow and freezing weather occurred in Hubei, Hunan, Guizhou and other places, affecting Spring Festival transportation. So will this cold wave bring similar impacts?
The Central Meteorological Observatory stated that due to the obvious warming in the early stage, this wave of cold air is mainly to "correct" the obviously higher temperatures in the early stage, and the temperatures in the north and south will briefly fall back to normal levels for the same period of the year. From tomorrow night to the 15th, there will be light to moderate rain in Jianghuai, Jianghan, northern and western Jiangnan, western South China, Sichuan Basin and Guizhou, and light to moderate snow in parts of central Inner Mongolia and northeastern Inner Mongolia.
Since the temperature in the south has not been low enough for snowfall after the cooling in the south, it will mainly be rain this time, so you don’t have to worry about snow and ice affecting travel. After the cold air passes, temperatures in various places will rebound quickly.
The Shanghai Municipal Meteorological Department reminded that it is currently the peak period for returning from the Spring Festival holiday. Pay attention to the impact of low visibility and precipitation on traffic, and pay attention to approaching weather forecasts and warning information in a timely manner. Pay attention to the impact of windy weather on water transportation and the latest travel information. Put away outdoor items that are susceptible to strong winds in time to prevent falling objects from heights. During strong wind warnings, do not stay near simple temporary structures. In cold wave weather, pay attention to preventing respiratory system and cardiovascular and cerebrovascular diseases, and add clothes in time to keep warm.
