Will the court order my children's mother to be removed from the home and supervised visits due to drug and gun charges?

My children's mother was recently arrested for possession of meth (more than 10 grams but less than 28) and possession of a handgun with already being a felon for DUI's and OWI's and numerous driving while suspended. Her parents are the de facto custodians and she lives with them when not in jail and has been for 10 years. She became a non-custodial parent when I provided CPS allegation reports of physical/mental/drug abuse and reports of her parents stating they have a safety plan for the children to never leave them alone with her along with her admitting she is mean when she runs out of her prescribed medication for being bipolar and a manic depressant. Will the court grant a motion to not allow her to live with them anymore due to her recent arrest/behavior/negative impact if she is to bond out or get home detention from her charges?
