How's the weather recently? Why is it always rain or shine?

Due to the war between cold air and warm air, the weather has been sunny and rainy recently. Generally, at this time, cold air mainly brings us precipitation weather, which has little effect on cooling and gale. Next, we should focus on the strong convective weather such as lightning and short-term heavy precipitation brought by cold air. At present, it is predicted that it will be cloudy except for the northwest airflow behind the trough on the 6th to 7th, especially after the 8th, when the weather will be unstable and there will be staged concentrated precipitation.
