Hi, thought I'd chime in, to no one's anticipation.
Weather - clouds could break, but I did a look-see of the GOES satellite and clouds are thickening from the SW (where this flow is coming from). Still could easily be breaks in the clouds here and there, but generally not going to get an unobstructed total view, which is amazing. My guess though is clouds slightly worsen as the low in Nevada starts throwing clouds our way the rest of the morning. Hope there are some peepholes though.
Eclipse tidbits:
1) Once the sun *completely* is obscured by the moon, it's absolutely ok to look at it without eye protection (no "hidden" damaging rays or whatnot). But once *any* (and I mean even .001%) of the sun breaks back out, you'd better not be looking. Everyone's retinas are different - mine can absorb a quick glance but some people get permanent blind spots. Know the start and end time to within a few secs.
2) Don't waste time jacking with equpiment and miss it. Take a picture or video but the best part is experiencing it with full attention. Trust me on this. Plus there will be billions of pictures/videos of it, even if you pride your own.
3) If you've never seen a total, it's galactically different, and I mean hugely, than even a 99.99% partial. The coolest thing you can experience is that last .01% shadow of the moon creeping over the land and then at your site. Everything changes in an instant. You go into a completely different world with that .last .01% disappearring.
4) How dark does it get during totality? NOT 100% black. More like 30 mins. after sunset. Dark blue. But that amazing black disk above provides a sort of heavenly shadowy light. Nothing like it. I'll leave you with a shot I took of the 2017 clipse in Illinois, ironically enough the exact same spot where this one will cross (center of the "X" of the two tracks if you will). I had enhanced the moon's blackness a bit in this (not totally, pun intended) as often the sun, even eclipsed, will bleed into the black moon and wash it out (doesn't happen with naked eye).
Hope you can get a peek at least. Nothing like it (alas, on a clear day, though).
2017 (sky is about the right color, in real life maybe a shade darker (camera tried a bit to adjust the light, but it's about 90% accurate IMHO):
