There’s only 17 hours to go until the eclipse, and we are now within the range of the latest HRRRX (Experimental High-Resolution Rapid Refresh) model! This is exciting because the HRRRX takes the decrease in solar radiation due to the eclipse into account. Take a look at the predicted incoming solar radiation tomorrow and see if you can track the path of the eclipse. It’s not too difficult. 🙂
The HRRRX also shows cloud “ceilings”, which is the height of the lowest level of clouds that covers at least half of the sky. In Oregon, skies look clear for everywhere except the coast. Thankfully, you won’t have to go far inland to get away from the marine layer. There are a few high clouds over Washington, but these shouldn’t have much of an effect on viewing.
The UW WRF-GFS paints a similar picture, with clouds hanging right off the coast and offshore and a few high clouds over the Washington Cascades. There’s still the potential of a few low clouds in the downtown Seattle area close to Puget Sound, but you won’t have to go far from the sound to get away from these clouds.

As the below satellite image shows, the majority of smoke still looks to be to the south of the path of totality in Eastern Oregon. These high clouds should also be gone by tomorrow, giving us crystal clear skies for the eclipse.
In short, things are looking great for the vast majority of eclipse viewers. If you are on the coast, you’ll want to head a couple miles inland to get out of the low clouds. Some smoke may be around in Eastern Oregon, but it won’t have much of an effect. And the conditions in the Willamette Valley will be downright spectacular.
I was reflecting last night on how scary a total eclipse must have been for those who didn’t have a scientific explanation for such a phenomenon. I’m looking forward to the eclipse not only for the dramatic change of scenery and the chance to see the sun’s corona, but as a way to spiritually connect with past generations and appreciate all the wonders that science has to offer. I hope you all are looking forward to it as much as I am!
Peace and love,
Charlie
