Both of you are probably right. I understand that Rain accumulation map figures are from reference time of the model run. In the Meteogram if you show UTC time (in Settings select Display all time in UTC) you see missing hours from the run start in North America. Here in Europe we are closer to UTC and there are less discrepancies. It's just an assumption, I’ve not checked everywhere.
