There's a weather ball in Flint, MI. The saying goes,
"When the Weather Ball is red, warmer temperatures ahead. When the Weather Ball is blue, colder temperatures are due. Yellow the Weather Ball, there be no change at all. When Weather Ball blinks in agitation there'll be precipitation."
So I created one that points at my weather station and specifically it's pole.
If the high tomorrow is 5 degrees or more than today it'll be red. 5 degrees lower it'll be blue. If its within that 5 degrees it'll be yellow. If the forecast includes any number of words for rain or snow...it'll flash every 10 mins for 30 secs.
Yes I know I need to mow lol.
