We’ll have a 1.7.1 bug fix release before 1 Sep 2025 that will update the MetPy NEXRAD clients.
In conjunction with the AWS Open Datasets team, we are changing the AWS S3 bucket that contains up-to-date NEXRAD Level II archive data. There is a new bucket name and SNS notification topic, but no other changes. The legacy bucket name will be discontinued September 1, 2025. buff.ly/WVBvt26

Now we are bringing in the ensembles & as a reminder to folks why @metpy.bsky.social is a powerful tool since vorticity isn't a field in the ensembles like it is in the deterministic models. However, we can use metpy.calc to calculate vorticity from the u & v wind components in the ensemble field.
