Folks have already looked at cloud cover a climatology for the 2024 solar eclipse. It looks something like this, with generally more cloud cover the farther east you go. Though now that this winter will likely be ENSO+, how does that affect the cloud cover climatology?

I used ERA5 cloud cover every 6 hours from April 1-15, 1940-2023. For the ENSO state, the February-April ONI≥0.4 is El Niño and ONI≤-0.4 is La Niña. (1/2)

Not quite what I expected. I expected less cloud cover over the south during El Niño due to a stronger subtropical jet. But there's actually *less* cloud cover over TX and the lower Mississippi Valley during El Niño Aprils. Also maybe a bit more cloud cover over the lower Great Lakes. (2/2)
