It also saves the weather information (e.g., «partly
cloudy, 61 degrees at first pitch with a high of 68 degrees») and provides interesting factoids about what

on that same

But, hey, all you have to do is go outside
on a partly
cloudy day and see what
happens when a cloud blocks out the incoming sunshine.
