Does it really start to rain most frequently between 5:00 - 6:00 PM, or does it just seem that way?

I realize that I would be more aware of rain during that time, because it corresponds to commute time, but it does not rain all that often during the morning commute. It also seems that weather forecasts seem to most frequently talk about possible rain in the late afternoon. You can’t get any later in the afternoon than between 5:00 and 6:00.
