This is the first time an entire state has a mean PWI over 9. The lucky winner tomorrow May 11th, 2012 is: Virginia (mean=9.04). They are followed closely by Indiana and Washington DC both with an even PWI 9. If you round up, you can add Kentucky to that list (mean 8.996). Southeast Virginia has a very large area of perfect 10 from Richmond south down I-95 to the North Carolina border. A smaller area appears in far western Ohio and SE Michigan. Some perfect 10 cities here are Greenville, Ohio and Ann Arbor, Michigan. Overall, the national mean is again 7.1 which pretty darn good.
On the lower end of the scale, you can plainly see a front sweeping down the Upper Plains. The lower scores from Minnesota to Colorado are mainly due to strong wind, lots of clouds, and cooler temperatures. There will be some showers, but not widespread rain. Again, Maine is on the bottom with a mean of 4.6, but that’s better than yesterday. Hang in there Mainers, your time will come!
I thought I would give everyone a sneak peek at the Mother’s Day perfect weather index for Sunday. It looks incredible, especially for the West and the Upper Plains! The mean is 7.6! There are no PWI 1’s or 2’s, but not many 10’s either. My pick for Mother’s Day is Lindsay, Montana which is closest to the area perfect 10’s just to the west.
