Several factors explain the unusual cold that settled over the United States this spring. One has been the unusually heavy snow cover in Canada and the northern United States.
This year's snow cover is deeper, colder and extends farther south than last year. That's helped chill the already cold Arctic air flowing south into the country. So it has helped amplify conditions contributing to our cold spring.
