a large sphere on top of the citizens bank building in downtown flint michigan, s. saginaw st. to be exact... a local landmark of sorts... it glows, and the color indicates the next day's weather. red= warmer, blue= colder, yellow= the same temp. if it is blinking then it means precipitation.
person 1: did you see the weather ball?
person 2: yeah it was blinking yellow.
person 1: dammit, i hate rain!
