A down day on the PWI with very few 10s to be had Friday. Some small areas of 10s high in the mountains of Colorado, Nevada, and California. The worst weather will be in New England with Maine coming out on the bottom. Overall, the heat and precipitation will keep the entire country down.
Salt Lake City, Utah is the place to be on Memorial Day as perfect 10 weather can be expected. This good weather extends into Idaho and Nevada. Overall, Utah will have the highest mean at 8.8, while New Hampshire will definitely be the worst at 2.7. In fact, all of New England will see poor weather for the holiday.
Best: 1. Utah 2. Nevada 3. Idaho 4. West Virginia 5. Washington
Worst: 1. New Hampshire 2. Rhode Island 3. Massachusetts 4. Vermont 5. Minnesota
A four-way tie for first on Sunday with Idaho, Nevada, Utah, and Vermont all having a mean score of 8.8. Technically, Idaho is the winner because it has the most number of perfect 10s including Idaho Falls and Pocatello. Heat, humidity, and thunderstorms make for the worst weather in the South. Although, Alaska has the worst mean of 4.9 but parts of the state will see nice weather including the Panhandle and the interior.
Best: 1. Idaho 2. Nevada 3. Utah 4. Vermont 5. Oregon
Worst: 1. Alaska 2. Louisiana 3. Mississippi 4. Alabama 5. Tennessee

After thinking more about what I posted yesterday about how the Perfect Weather Index model could be as much as two categories off and still yield a perfect 10, I decided to make some changes. Perfect weather should not come from averaging, it should come from what I strictly define as perfect. So rather than taking the mean of each of the criteria, I now sum all the point value. If it does not = 100, it’s not perfect…that is to say, a 99/100 is now treated at a 9 rather than rounded to a perfect 10. I expected less perfect 10’s on the map as a result, but there are actually more than I have ever seen. I’m not exactly sure why, but it could be that the weather is just so outstanding tomorrow.
As for the weather Monday, the West is best…mainly the Inter-mountain West. Utah comes in number one, followed closely by Nevada. New England will have another fine day, but the summer air is knocking on the door as temperatures and humidity begin to rise. Rain in the south keeps Georgia and South Carolina at the bottom.
So where are the most perfect locations? As I said there are quite a few so I’ll just throw out some select cities: Cornville, Maine…Wheatland, Wyoming…Salt Lake City, Utah…Twin Falls, Idaho…Wells, Nevada…Chemult, Oregon.
1. Utah 1. Georgia
2. Nevada 2. South Carolina
3. New Hampshire 3. North Daokta
4. Oregon 4. Ohio
5. Connecticut 5. Arkansas

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%!
1. Utah 1. Washington
2. Michigan 2. Florida
3. Kentucky 3. Oregon
4. Wyoming 4. Louisiana
5. Indiana 5. Texas

Kind of a shock to see so much beautiful weather across the nation tomorrow, May 9th, 2012. Almost everyone will enjoy some of the best weather of the spring! The notable exceptions will be Maine (mean 4.1) where a very rainy storm will linger another day, and portions of Michigan (mean 4.8) where some showers and breezy conditions can be expected. From Kentucky to California and North Dakota to Texas, widespread PWI 8’s and 9’s. In fact, almost the entire state of Kansas will be a PWI 9 (mean=8.98). The mean for the nation is 7.2 which is well above anything I’ve seen yet.
Getting a 10 was harder than I expected so I adjusted the model just slightly in the area of cloud cover. So now, I allow up to 25% cloud cover and still receive full points. I figure a few cirrus clouds or fair weather cumulus won’t mar an already beautiful day. Today, while there are many more PWI 10’s on the map, they only represent 0.0008% of the well over 1 million grid points. Out of the 10’s on the map, Utah has the most but few have a city in them. My pick here is Altonah, Utah. One of the largest concentration of 10’s is in southwest Oklahoma. A great one here is Acme, Oklahoma. Enjoy spring everyone!

An outbreak of spectacular weather for the Inter-mountain West for May 8th, 2012! This is the nicest weather I’ve found thus far doing this blog with the mean across the nation just a tad over a PWI 6. This is despite New England dragging the index down with a good soak tomorrow. Good for my garden though! By far the best weather in the nation will be any basin in the West. The Treasure Valley of Idaho, the Wasatch Front in Utah, all of northern Nevada and many other areas will see 9’s. Some of the best bets tomorrow will be Twin Falls, Idaho, Salt Lake City, Utah, Reno, Nevada, Walla Walla, Washington. Outside the West, really the only place I can recommend is the Kansas City metro area.
I’m starting to think the perfect 10 is too elusive. Out of all that amazing weather in the West, not one pixel of perfect 10. I may have to adjust the model slightly if I can’t get any 10’s. What’s the point of having the scale go to 10 if it never gets used?
