If you are going to be in the totality corridor this weekend, then it's time to be looking at the Monday forecasts along the eclipse path to inform your decision of where the best weather is close to where you are.
If these forecasts hold, the most interesting anomaly is the very clear forecast for Salem, Oregon, which is expected to receive a large volume of visitors through Interstate 5. The forecast for clear weather in Illinois, Kentucky, and Tennessee is also unexpectedly good for that part of the country. The Idaho and Wyoming forecasts are consistent with the clear skies that prevail in that part of the country this time of year. WPO still recommends Idaho and Wyoming as the safest bets weather-wise.
