Here's the common way to use a semicolon with a transition word like "however":
1. Independent Clause; Transition Word, Independent Clause.
Example:
* The weather forecast predicted sunshine; however, it started raining heavily in the afternoon.
In this case, the semicolon joins the two independent clauses, and the comma follows the transition word "however."
Important Note: You can use other transition words besides "however" with this structure, such as:
* nevertheless
* therefore
* consequently
* moreover
* furthermore
