Today (March 5).
It is a sting in the 24 solar terms.
It is also the beginning of mid-spring.
Due to the arrival of cold air.
Since last night, the whole province of Jiangxi has cooled down.
As the saying goes, "If the cold of spring comes, you need to see the sting".
So this year's "inverted spring cold".
Will it come? 
Nanchang Meteorological Observatory forecaster Lei Xingyu: Today, Nanchang is a cloudy weather with showers and thunderstorms, and then starting tomorrow, the rain will gradually stop, and tomorrow has turned into a cloudy and cloudy weather, and the day after tomorrow is from the 7th to the 8th, which is a sunny and cloudy weather.
Whether the cold of spring comes, you need to see the sting", is the experience of the ancients based on the observation and summary of natural phenomena. They believe that from the weather conditions on the day of the sting, they can preliminarily predict whether there will be cold spring weather in the later period.
Lei Xingyu, forecaster of Nanchang Meteorological Observatory: The inverted spring cold refers to the rapid drop in temperature due to the influence of cold air after the temperature rises in spring, which basically occurs from late March to April.
Lei Xingyu introduced that after the sting, the temperature will gradually rise, but due to the frequent cold air in the later period, there will still be a "cold spring".
Lei Xingyu, forecaster of Nanchang Meteorological Observatory: Remind everyone to pay attention to weather changes in a timely manner, and pay attention to increasing or decreasing clothing in time before the spring cold comes, and beware of colds.
The urban scene reporter learned from the Jiangxi Provincial Climate Center that the average precipitation in the province is expected to be more than 1 to 3 percent in March this year, showing the characteristics of less before and more after more, and in the second half of the month, the precipitation has a strong trend. Strong convective weather such as strong thunder and lightning, local thunderstorms, strong winds and short-term heavy precipitation are more likely to occur, and all localities, especially in northern Jiangxi, should pay attention to preventing small and medium-sized river floods and mountain floods that may be caused by local heavy precipitation. There is a high probability of periodic spring cold from the end of early to early March and early to early April.
