Utah appears at the top of the Perfect Weather Index list tomorrow for the first time with a mean of 8.1. A number of perfect 10’s appear in the state Thursday as well, including Wanship, Wallsburg, and Burrville.
The greatest concentration of perfect 10’s though, will be in Wyoming. Again, just west of the Big Horn Mountains, a significant area of perfect scores appear, including such towns as: Frannie, Ralston, Burlington, and Grass Creek. In the southwest portion of the state, Granger and Little America will also be perfect.
Another large area of 10’s appear in eastern Idaho, including Pocatello, Blackfoot, and Neeley.
Outside the West, a few perfect 10’s show up along Lake Michigan in northern Indiana and northern Michigan. Some cities here include: Michigan City, Indiana…Elk Rapids, Michigan…and Lincolnwood, Illinois and Hyde Park around Chicago.
I thought it would be interesting to look at the distribution of scores today. This graph shows the total number of grid cells for each PWI score. It clearly shows just how difficult it is to achieve a perfect 10, or for that matter this time of year, a PWI 1. The total number of grid cells is over 1.3 million so percentage wise, the number of perfect 10’s is only 0.0016%!
