Not sure what “sunshine duration (1h)” precisely means, but I like that a LOT more than the cloud cover %. GFS shows 0 mins for TX, but euro is like 30-50 mins for eclipse time.
Tomer changed his % of clear sky solar radiation metrics to 85/60-85/<60, which wasn’t favorable for TX lol. I’m still hugging the GGEM which looks mostly clear for me during eclipse.
All I’d recommend is picking your spot, get there early, and leave well after totality. Most people will get back in the car right after totality ends. Stay put for another few hours and hopefully traffic calms down.
Tomer’s eclipse city dashboard shows 77% of ensemble members have “favorable” or “somewhat favorable” conditions for eclipse viewing west of Austin. Despite the NBM showing 65-80% cloud cover. So maybe that implies just thin cirrus?? That’s what I’m hoping for at this point. I’ll definitely take the under on just about any prediction of convective cloud cover around the totality path. As I recall from 2017, only the hrrr actually accounted for the reduction in insolation? And it made a visible difference in cumulus coverage.
