From subzero cold in northern Maine to 90s in Southern California, enormous temperature contrasts spanned United States over the weekend.
In every corner of the nation, new records were established, showing off its enormous diversity of extreme weather:
Anchorage experienced record warmth and set a snowfall record on the same day.
Los Angeles set a record high of 93 degrees.
Key West, Fla., finished its longest stretch in recorded history with high temperatures at or above 80 degrees.
