Narrative:

It was the end of a long duty day flying north towards cincinnati just east of R-5503A. Heavy thunderstorms created many diversions on ATC. We were flying along and given new route and radar vector. Upon change of ATC frequency, given another route along with vector. I was now struggling to find new route on low charts and the PF became occupied with helping in the navigation. Looking up from the charts, I informed her (PF) she was right of vector approximately 40 degrees. Turning back on course, ATC informed us of close proximity to restr area and gave new heading. Factors affecting flight consisted of fatigue, WX, heavy cockpit workload, and focusing our attention on the radar for WX avoidance without having proper charts readily available.
