When I was in 6th grade, I had to do a project that was EXACTLY like this except we got to pick our own place. My friend and I did Venezuela.
This isn't that hard. Just go to you search engine and type in "description of climate in (the southern state you pick(ed))"
Do that for every piece of information you have.
I cannot do this for you because it's a project and asking someone to do on here it is basically against Brainly rules(which is why someone probably reported this(it wasn't me, I swearmy life))
To make a brochure, use a your computer software. There is one on Microsoft Word.
You can get images off the computer. (I'd do that rather then drawing them)
Use accurate sites for information like Britannica or whatever. Nothing like from sites like Wikipedia, Y!A, or things like that.
Best of luck!
