Why doesn't it snow so much this year?

Because the snow season has passed this year.

Now that it has entered the spring, the weather is getting warmer and warmer, and there is no condition for snowfall. If there is precipitation, it will rain, and it won't snow again.

Snowing is related to weather changes and ambient temperature. Snow can only be formed when there is precipitation in a low temperature environment, so it often appears in winter or extremely cold places.
