從香港天文學會於該會論壇內發表有關2017年8月21日美國日全食觀測地點選擇的文章內容得知懷俄明州 ( Wyoming ) 東部地區於八月份的晴天出現率較西部地區為高。例如位於懷俄明州東部的道格拉斯市 ( Douglas,北緯42.7593°,西經105.3826° ) 其晴天出現率為83.6% ( 觀測記錄共441份 ),而托林頓市 ( Torrington,北緯42.0640°,西經104.1844° ) 其晴天出現率為83.9% ( 觀測記錄共317份 ),而接近全食帶中心的卡斯帕市 ( Casper,北緯42.8385°,西經106.3123° ) 其晴天出現率為80.2% ( 觀測記錄共983份 ) 。

閣下有意於2017年8月21日到美國進行日全食觀測,本人參考香港天文學會於該會論壇內發表有關是次日全食觀測地點選擇的文章內容,愚見認為暫時最佳觀測地點會是俄勒岡州 ( Oregon ) 的安大略市 ( Ontario,北緯44.0233°,西經116.9729° ) 及亨廷頓市 ( Huntington,北緯44.3490°,西經117.2663° )。從全食帶途經的美國州份八月份氣候數據得知愛達荷州 ( Idaho ) 博伊西市 ( Boise ) 的晴天出現率高達91.4% ( 觀測記錄共1011份 ),鄰近的安大略市的晴天出現率高達92.7% ( 觀測記錄共355份 ),而接近全食帶中心的亨廷頓市在地理上接近上述兩個城市估計晴天出現率會相當高。但現在仍未知道香港天文學會會否組團到上述城市進行觀測活動。
The planning for the 2017 solar eclipse was triggered by a veteran member of HKAS who lives in USA.
Depending on the planned observation, the exact location need not be too precise, as we can always drive to avoid clouds, unless heavy equipment is involved.
Sometimes, statistics is statistics, and there is no sure way to get a clear sky, so we must prepare to be mobile.
I was touring Arizona in the first week of May, after going to my daughter's graduation at U of Michigan. We have always think Arizona to be a desert with high air temperature, but we never have had a chance to wear shorts or just T-shirts! When we drove from Entelop Canyon to Flagstaff, the temperature fell from 46F to 34F after 30 minutes's drive, and I was treated to my first ever snow during the next hour of driving. Upon arriving the Lowell Observation in the evening, the ground was covered by snow. It was all snow the next morning.
Another consideration is to avoid too many people at any location, or the cost of lodging will be too expensive.
Thus, we should spread our locations to maximize the chance of a successful observation.

Yellowstone is worth visiting.
My experience in August is 60% clear and absolutely blue sky and 40% (at least partially) cloudy .
But given the eclipse ends after 7 pm. You may want to stay in Yellowstone for the evening (any outside town is >2 hours drive). It is still August which is a peak season, you more or less have to book your accommodation a year ahead.
BTW, you expect 6.5 hours of total darkness if you want some night sky observation.
