Not quite as nice as yesterday with the mean PWI down just a hair (still a PWI 7), but another brilliant weather day for most of the country. There are two areas of perfect 10’s tomorrow May 10th, 2012. The first is in north-central Missouri around the town of Dalton. The second area lies along the border of Tennessee and Alabama. A couple of good picks here would be New Market, Tennessee and Woodville, Alabama. Overall, Missouri scores the best with an 8.98 followed closely by Illinois. Poor Maine just can’t catch a break this week and again has the lowest score (mean 3.3) and up to another inch of rain for parts of the state. Although, Montana will see the largest area of low PWI , only the far eastern plains prevents the entire state from being the low point in the country (mean 3.9). Surprisingly cold, wind, and wet in west Texas tomorrow produces some low scores there as well, though they really need the rain.

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!
Southern California is living up to its reputation of perfect weather this week with a string of excellent days, though nothing with a perfect 10. A narrow strip of 9’s appear on the map from San Bernardino south to Hemet, California. This is away from the coast where fog and clouds will persist longer and keep temperatures in the 60’s, but not so far inland to the deserts where it will be above 90 degrees.
Outside of Southern California, not much above PWI 8, except in the foothills SW of Denver, Colorado. There is a small area of PWI 9 around Indian Hills, Colorado. Why the foothills and not in Denver proper? Highs in Denver will go above 80 degrees, slightly warm for my taste.
I altered the color scale to give it more contrast and make it easier to read.
I suspect that this will be more common than not. There are no perfect 10s on the map for May 2nd, 2012. Perhaps the winds are a little breezy, or maybe there will be some high thin clouds which prevents the perfect score. Either way, the index is designed to show a “prefect” day, not a fine day, of which there will be many. If I were in Fargo, North Dakota tomorrow, I certainly wouldn’t complain with a score of 9, but it demonstrates just how picky I am. Another excellent choice tomorrow: Sacramento, California.
This is the very first perfect weather index blog entry. I hope others are as interested as I am in the pursuit of an “ideal” weather day. So how do I create these maps and what are my criteria? Well, it’s a complicated scientific process using GIS (Geographic Information Systems) and total subjectivity. In my mind, 72 degrees, a light breeze, low humidity, and full sunshine is perfect.
So is there some place in the USA that lives up to this high standard tomorrow April 30th, 2012? Only one. 33.736, -109.582 is the latitude and longitude of the location. Where is that? Well, it’s in Arizona in the middle of NOWHERE! I’ll call it Tonto Lake, but the nearest town is 20 miles to the NE called Nutrioso, AZ.
