Independence Day - Fireworks and Thunder

We celebrated Independence Day in the traditional fashion -- BBQ and fireworks.  What seemed odd, though, was the weather.   July heat is not news.  But, it sure seems that we are getting a lot more humidity than we used to.   It was hot and cloudy last night out in Chino (where fireworks are legal and sold on nearly every corner).   As we waited for the sun to set, it looked like someone to the west was getting rain.
