I understand where you're coming from, Anita. I'm in central New Jersey, which is a bit milder than interior Pennsylvania on average, but I do not remember any particularly cold winters since 2014/15 (especially February 2015). So, this has been the coldest start to winter for this part of the country in recent memory. I would hesitate to blame La Nina, however, as we generally do not see such a La Nina temperature influence in this part of the country. It will be interesting to see how long this colder pattern persists and to diagnose the causes afterward, if it does.
