Developing a Paragraph by Comparison and Contrast

When it comes to summer , the biggest feeling is that it is so hot out . It is sunshine and the great bursts of leaves growing on the trees . The weather is weird , sometimes we got hit by a pop-up sudden storm yesterday , and all of a sudden it started raining cats and dogs . In contrast, it is too cold in the winter . When winter approaching  comes, the snowflakes danced in the air , everywhere was in the white is a picture  of white.

Notes: I have done a minor change to this sentence

It is sunshine and the great bursts of leaves growing on the trees.

You could write a sentence like this. However you would more often see

It is sunny and  there are  great bursts of leaves growing on the trees

The word sometimes in the sentence below is not a good fit with the punctuation.

The weather is weird , sometimes we got hit by a pop-up storm yesterday and all of a sudden it started raining cats and dogs .

Perhaps the construction.

The weather is weird sometimes, like yesterday we got hit by a sudden storm and all of a sudden it started raining cats and dogs.

The comma after sometimes alters the sense of the sentence.
