On today (Friday) or Saturday you will have to click the Forward Two Days button near the top of the screen to see the numbers for Monday and the eclipse time.
Unfortunately the number where I was thinking of going is over 50%.
Cool. I’m in Wisc and going to the Springfield area to see it. I am leaving Monday morning and will find a parking spot when the traffic gets bad or the eclipse starts.
Use Form B so you can enter your exact coordinates. When you Get Data, you will see more than you need. Just remember the times are UT, Universal Time. If you got this far, convert UT to your local time should be easy.
We’re forecasted for clear skies on Monday in the South Bay. I expect SF will be foggy, as usual this time of year. One month later and we’d be in the time you’d expect clear skies up in the city. But then we’re only 75% eclipse, and my experience from having watched one from “ground zero” years ago is that you don’t really notice much until you get to more like 90% coverage of the sun. I’ll be out checking it out, but I don’t expect to see much.
Figures. Nearly 300 sunny days a year in this town and the morning is overcast. Well, they’re saying about 50% at noon local time, so maybe we’ll get lucky.
57-58% in west Michigan. Right now, it looks about 100% covered, although that weather tool says 54%, so we’ll see what things look like in a few hours.
