May 14th, 2012
It was a lovely Mother’s Day weekend over most of the country, but today there’s a lot of rain along the east coast from the Carolinas to New England. Behind the rain, some there’s some beautiful weather, especially across Michigan. This is the only place where an appreciable number of perfect 10’s appear, and what’s interesting is they appear in a narrow strip away from Lake Huron. Near the lake, it’s slightly too cool for a perfect 10 with highs in the upper 60s, and in the interior it’s slightly too warm in the mid 70s. Overall, the mean in Michigan is 8.8 which is the best in the nation. My pick of the day is Bay City, Michigan. They are followed closely by Missouri (mean 8.6). West Virginia is at the bottom (mean 5.0) with a whole bunch of rain expected and cool temperatures.

For tomorrow May 15th, 2012, not quite as fine as today but still a lot of good weather around the nation. Ohio should be the best with a mean of 8.8. They are followed closely by North Dakota and Indiana. More rain for New England keeps that region generally under PWI 6. And you’ll notice the extreme heat in Arizona takes a toll on the index there. Only the mountainous areas reach PWI 8. There are just very isolated pockets of perfect 10’s tomorrow, all west of the Mississippi. California will have the most and I would pick Moorpark in Southern California or Bowman Lake in the Sierra’s as the perfect weather locations. In Oregon, Rhododendron in the Cascades will perfect, and Cowdrey, Colorado also scores a 10. Worst weather will be Connecticut, Vermont, New Hampshire, and Maine…in that order.
May 10th, 2012
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.
May 9th, 2012
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.
May 3rd, 2012
Only portions of California and a spec in South Dakota even reach the 9 on the perfect weather index tomorrow May 3rd, 2012. Areas around Bakersfield (mainly on the west side of the San Juaquin Valley) will see the best weather in the nation. And as I mentioned, one tiny area around Oelrichs, South Dakota gets to a 9. Certainly not a bad day around Philadelphia or the mountainous areas of the Southwest. By far the worst weather will be found in the southwest part of Oregon and Northern California. Brookings, Oregon is expecting 1-2″ of rain and gusty winds. Hot humid and windy from west Texas to Chicago makes for low perfect weather scores.
I changed the map projection to Albers Equal Area Conic if any GIS nerds are interested. I also noticed the scale has been changing based on the top score. It should always read 1 to 10.
