Thanks for your comment, Craig. The changes in the jet stream certainly have impacted conditions over the U.S. this winter. We have seen a stronger-than-normal jet stream throughout the Southwest, which has brought the wetter conditions this winter. Regarding whether the increased "waviness" is linked to Arctic amplification, we do not have a scientific consensus on such a link. This connection has been hypothesized, but the evidence is mixed. However, climate scientists continue to investigate this topic, and hopefully we will have greater scientific consensus in the years ahead. 

Even with the mild winter in the East, we had two notable cold spells, one in late December and the other in early February, so there have been some wild swings this winter!
