Anyone recall seeing a game in Denver, around 1978-79......

Where the game started out in beautiful weather but by the end, you could barely see the field. I DO recall it was New England they were playing. They also had a blizzard game on MNF in the mid 80s. That late 70s game blew me away because it was shown here. I recall watching some of the first half, doing something else till mid 4th quarter and then not thinking they were showing the same game.
