Eclipse Weather Outlook

One of our readers, Ian, has requested a weather forecast for this coming Sunday's ~7:30 PM solar eclipse.  I confess complete ignorance of astronomical matters, but do know a little something about the weather, so I may be able to help with the forecast.

The latest GFS and most of the medium-range ensemble forecasts call for a trough to be situated off the west coast with southern Utah in southwesterly flow aloft.

In such a pattern, the weather should be nice in the sense that it would be dry and quite warm, but it's impossible to say whether or not there might be some cirrus clouds floating around at the time of the eclipse.  Also, this is a fairly long projection - 150 hours, so we'll have to see how things shake out.  Keep your fingers crossed and we'll try to take a look at things in a few days.  Right now, I suggest being cautiously optimistic.
