On the night of the 24th, Jiangsu may usher in “first snow”

At 23:59 Beijing time on December 21, the solar term of “winter solstice” will be ushered in, and the “count nine cold days” will begin. According to the outlook of Jiangsu Provincial Meteorological Observatory on the weather of the week, there was a precipitation process in the province from the night of the 23rd to the 24th of this week. It is necessary to pay attention to the phase transformation of rain and snow along the river and southern Jiangsu on the night of the 24th, which may turn into light sleet or light snow.

Affected by the strong cold air on the 24th-25th, Jiangsu will have strong wind and cooling weather. The minimum temperature in 48 hours will drop by 10 12 ℃, accompanied by northerly gales of 5-7 on land and 7-9 on the sea surface of rivers and lakes. The minimum temperature will appear in the morning of the 26th: around - 8 ℃ along the Huaihe River and Huaibei, and - 5 - 6 ℃ in other areas. There is freezing in the whole province. In addition, we should pay attention to the foggy weather in the morning of 22-23.

After the “cold weather” of the previous two days, the temperature rose rapidly in the afternoon with the distance of the cold wave and the help of the sun yesterday. Today, the temperature along the Huaihe River is 14 ℃ in the north of Huaihe River and 15 ~ 16 ℃ in other areas. The temperature will be maintained in the short term, and the sun will be warm in the afternoon. The temperature is not particularly high in the morning and evening. It is expected that the minimum temperature in Jiangsu will be 0-1 ℃ in recent days, with a large temperature difference between day and night.

After the winter solstice, the climate in all parts of China will enter the coldest stage, that is, people often say “entering nine” and “counting nine cold days”. In the winter solstice in Nanjing, the temperature is 2.8 ℃ and the minimum temperature is - 1 ℃. In some years, the winter solstice is accompanied by extremely cold and low temperature. For example, in the winter solstice solar term in 2005, there was a low temperature of - 7.9 ℃ in Nanjing. However, on the day of the winter solstice this year, the maximum temperature in Nanjing is expected to reach 17 to 18 ℃.
