Looking at this red-hot temperature change map, with the blessing of the sun, do you feel warmer today?
Tomorrow and the day after tomorrow, such warmth will continue, and many places will experience the warmest day this year. The maximum temperature of 10 °C will reach the southeast of Inner Mongolia and the central part of Jilin, and the maximum temperature in a large area south of the Yellow River will exceed 20 °C. Among the large cities, Zhengzhou, Hefei, Nanjing, Chengdu and Kunming are expected to usher in the first 20°C+ this year.
But a strong cold air is already brewing! Tomorrow night, the cold air will depart, gradually bringing cooling to most areas, with some areas dropping by more than 10 degrees Celsius, and at the same time precipitation will increase. Everything you need to know about cold air is here↓↓
How drastic is the cooling from cold air?
From tomorrow night to the 15th, under the influence of strong cold air, the middle and lower reaches of the Yangtze River and its northern areas will have 4~6 northerly winds from north to south, with gusts of 7~9, and the temperature will generally drop by 4~8 °C, and the temperature will drop by 10~12 °C in some areas, and more than 14 °C in the northeast region.
Will it be cold after cooling down?
Due to the obvious warming in the early stage, this wave of cold air is mainly to "correct" the significantly higher temperature in the previous period. Temperatures in the north and south will briefly drop back to around normal for the same time of year.
After the cold air, the temperature will rebound rapidly, and the temperature in the eastern part of the northwest region, Huanghuai and the middle and lower reaches of the Yangtze River will rise to a new level, continuing to hit a new high this year. On the 18th, the maximum temperature in the middle and lower reaches of the Yangtze River will reach about 25 °C, and Jiangsu and Anhui may be locally warm and rare in the same period.
Will stronger cold air bring snow and ice to the south?
With the arrival of this strong cold air, 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 and northeast Inner Mongolia.
Since the temperature has not been low enough to snowfall after the cooling in the south, this time it is mainly rainfall, so you don't have to worry about the impact of snow and ice on your travel.
Will this cold air be followed by a cold spell?
According to the medium-term forecast of the Central Meteorological Observatory, from the 17th to the 21st, there will be a cold wave from west to east and from north to south to affect most parts of the mainland, and the temperature will drop by 6-10 °C, 12-16 °C in some areas, and above 18 °C locally. The central and eastern regions will also have a significant cooling on the 18th and 20th.
Among them, Xinjiang was the first to cool down, such as Urumqi, with a maximum temperature of 8 °C on the 16th, and a plummeting drop of -10 °C on the 17th, which shows that the strength of this cold wave is not ordinary. Due to the long time limit of the forecast, everyone should continue to pay attention to nowcasting.
Will there be rain or snow on the return trip from the holiday?
The precipitation brought by the stronger cold air will continue until the 15th, and during the peak period of the return trip on the 16th and 17th, the precipitation will subside in most parts of the central and eastern regions, which will be conducive to the return journey.
On the 19th and 20th, there will be rain turning to sleet or snow in Huanghuai, Jianghuai, and Jianghan, and light to moderate rain in the south of the middle and lower reaches of the Yangtze River, with locally heavy rain, and freezing rain in Huanghuai, Jianghuai, Hunan, and Guizhou. You should pay attention to nowcasting to prevent the adverse effects of rain and snow on transportation.
