@User47 @ikluft Yeah. Going to attempt to see an eclipse needs understanding and accepting the risk that weather can block the view. As Heinlein said, "Climate is what you expect. Weather is what you get."
Dropping temperatures can even cause clouds to form at exactly the wrong time, as I saw from Reno at the annular eclipse of May 2012.
The best strategy is to plan the trip to have other things to enjoy in addition to the eclipse. The eclipse depends on luck. But the other plans shouldn't.
