What does it mean that it will rain early next winter?

"It will rain in beginning of winter in the coming year" is a folk proverb that summarizes the solar terms. I understand the general meaning is:

The wet and cold winter can be said to be a very difficult stage. If it is rainy and humid in winter, it is not only difficult for people, but also difficult for farmers to store agricultural products after the autumn harvest. Under such weather conditions, agricultural products are not easy to store and are easy to rot. For modern agriculture, the rainy winter in early winter has other effects. Wet and rainy winter also has a great influence on some greenhouse crops. Humid and cold, insufficient light, easy to cause crop diseases and insect pests, is not conducive to the growth of greenhouse crops. Generally, in this winter, crops in greenhouses will basically reduce production to varying degrees, so there is a saying that "it will fall in the coming year."
