Description of the weather before snow

The day before the first snow (Jun Qing), the Meteorological Observatory released the news that the cold current from Siberia was going south. Yesterday, strong cold air invaded Jiaodong Peninsula. A few days ago, March was as warm as spring. Yesterday morning, the weather suddenly turned cold, and the air was full of lead clouds. At noon, the cold wind blew and blew all afternoon. The wind stopped at dusk and it began to snow. This is the first snow since winter. When it began to snow, it was accompanied by light rain. Soon, I saw goose feather-like snowflakes falling from the sky with dense clouds, and the ground turned white for a while. The mountain village in winter is very quiet at night, and only snowflakes keep falling. Let me know once in a while Dead branches were crushed by snow. It snowed heavily all night. In the morning, it cleared up and the sun came out. Push open the door and look, wow! What a heavy snow! Mountains, rivers, trees and houses are all covered with a thick layer of snow, making a world of powder and jade. The bare willows are covered with fluffy and shiny silver bars; Evergreen pines and cypresses in winter and summer are full of fluffy pines and heavy snowballs. A gust of wind blew, the branches shook gently, silver bars and snowballs fell rustling, and the snow powder like jade fluttered with the wind, reflecting the morning sunshine and showing a colorful rainbow. The snow in the street is more than a foot deep, and my feet creak when I step on it. Groups of children are making snowmen and throwing snowballs in the snow. As the saying goes, "Xue Rui heralds a good year." This is not superstition, there is sufficient scientific basis. Heavy snow in winter can freeze some overwintering pests to death; Snow water penetrates deep into the soil layer, which can supply the needs of fragmented crops. This heavy snow is very timely and will definitely bring a bumper harvest to wheat next year. The experienced old farmer compared snow to "the quilt of wheat". The thicker the quilt is covered in winter, the better the wheat grows in spring. So there is another proverb: "Wheat covers three quilts in winter and sleeps with steamed bread next year." I think: This is why people call timely heavy snow "Xue Rui".
