Changing Weather Pattterns affecting Planning?

To all who have trekked across the US multiple times in recent years:

Has anyone been bothered, interrupted or rerouted due to the “new normal” of climate change and troublesome weather? Before we buy an RV and head out from California to New England and back again, I would love to know of any bad experiences (weatherwise) that could have been avoided. Thanks very much!
