What Is Wrong With My Pine Tree?

Question

My pine tree became suddenly orange all over in a 2-day period. One day it was green and the next orange everywhere. I have only lived here for a year, but I can tell the tree is at least 30 years old. I have 2 other trees near it and am worried about a disease that could affect them all. I am familiar with pine beetles but am not seeing any signs of such bugs. What else could cause this to happen so quickly?

This article explains it a whole lot better than I could: http://web.extension.illinois.edu/state/newsdetail.cfm?NewsID=26364
