Affected by the continuous convergence of warm and humid airflow and cold air, most of southern China will maintain rainy and snowy weather until early March, and there will still be rainy and snowy weather in many places along the Yangtze River and its south, and the precipitation phase is complex. Under the frequent pressure of rain and snow, the feeling of dampness and cold in many places in the south is very obvious. When will the low temperature and rainy weather in Sioux City end? At present, with the warm and humid airflow strengthening and lifting northward again, a new round of precipitation will be online this week, and the temperature will rise slowly.
The Suzhou Meteorological Observatory predicted yesterday afternoon that the main precipitation process this week will occur from February 28 to 29, of which the rainfall on February 28 can reach moderate rain, locally heavy rain, and the weather in the rest of the period is dominated by cloud changes. Due to precipitation and cold air, temperatures fluctuated this week, with lows of minus 1 to minus 2 with thin ice, appearing on the morning of March 2.
It is still early for spring to emerge into spring.
It is especially important to keep warm on wet and cold days.
Qijiu River opens, ** geese come", since the rainy season, Sioux City has continued to have low temperature and rainy weather, but the grass is slowly returning to green, plum blossoms are beginning to bloom, willow trees have sprouted, and the breath of early spring is exuded everywhere.

It should be reminded that in the case of low temperatures, the impact of air humidity changes on the human body is more obvious. The body temperature is not only related to the air temperature, but also related to the humidity and wind speed, in the low temperature environment, the air humidity is large, and the body heat radiation will be absorbed by the water vapor in the air, accelerating the body heat dissipation, and special attention should be paid to keeping warm in wet and cold days.
