How can reading help me improve my writing skills?

Good questionThe more reading of articles and books published by specialists, the more understanding of the language including terms and phrases, idioms and the sentence form. It will have clear influence on writing abilities.

Sure it will - reading helps vastly 

Agreed with Hatim alamin Abdallatief Abdedaem.

Also, it aint bad to register for reading and writing classes.

If you want to write well, you must read well, and you must read widely. Through reading you will gain knowledge and you will find inspiration. As you read more, you will learn to read with a writer’s eye. Even grammar sinks in when you read. If you’re worried about memorizing all the rules of grammar, then just read books written by adept writers. Eventually, it all will become part of your mental makeup.

A well-read writer has a better handle on vocabulary, understands the nuances of language, and recognizes the difference between poor and quality writing.

A writer who doesn’t read is like a musician who doesn’t listen to music or a filmmaker who doesn’t watch films. It is impossible to do good work without experiencing the good work that has been done.

All the grammar guides, writing tips, and books on writing will not make you a better writer if you never read. Reading is just as crucial as actually writing, if not more so, and the work you produce will only be as good as the work you read.

The more reading of articles and books written by professionals, the more knowledge of the language including words and phrases, idioms and the sentence construction. It will have definite impact on writing skills.
