Welcome, It is good that you understand that this tree needs to be outside to insure it gets it's required dormancy.
It would be best if it were to get a dormancy this year, However it must become acclimatised to the cold over the course of several weeks.
Do you have any cooler area you could transition it to? An unheated room would be an excellent first step, Then perhaps moving it to an enclosed porch, And then an unheated garage which would be an excellent place for it to winter. [provided it's cold enough]
Here are a few links for you to peruse to learn about your Juniper and bonsai in general.
I would check out the general care articles at these two as well as the articles on watering, Overwintering, and Soil to get a start on your general bonsai knowledge base. Both of these links are to well respected pro's in the bonsai community. Their advice in the articles is invaluable IMO.
A species guide for your Juni:
I didn't see your reply before I posted this.
The only thing I really have is a deck... Its been in my room the past 3 days.. Although I could open a window or something... Would this be beneficial?
Will it fit under the deck? Keeping it out of the wind IS important [More so than the temp for the most part.]
It requires temps below 40f [4C] for an extended period [Months] so opening your window is most likely not going to do the trick.
