Just minor differences in the underlying image edges in test_declarative_events with Matplotlib 3.9.0rc2. Diff:

Probably should just regenerate for Matplotlib 3.9, set a higher threshold for older versions. Unfortunately, Matplotlib 3.9 is requiring Numpy >=2.0.0rc1 to build, so we're not getting conda-forge packages any time soon.

[winash12]

https://github.com/winash12/MetPy/actions/runs/10019131680/job/27695339552 I am getting a nightly build failing again.

[dopplershift]

Looks like this is due to numpy 2, as this is showing up on the doc builds in #3578. We'll fix it over there in getting numpy 2 included in our CI.
