You've heard me say this countless times over the years. I really don't put a ton of trust in daily model data further out than 7 days. (Contrary to popular belief, 7 day forecasts are far more accurate than they were 15-20 years ago.) They do give a nice overall picture of the pattern across a large region like the mid-west or Great Lakes. This provides information like "above normal rainfall or below normal temperatures" which are definitely usable. However, deriving a detailed hourly forecast this far out will always invite problems. Keep this in mind as we close in on Eclipse Day.
For what its worth, here is what the GFS model is showing from late Saturday April 6 through late afternoon Monday April 8th. This is middle altitude cloud cover percentage.
I wouldn't use this information to plan your eclipse viewing as we still have time before the hourly forecast details become better in focus. If this verifies, cloud cover will be a problem
Another update on Friday.
