100 degrees in April? This past Sunday was 39th anniversary of the warmest day recorded in Fargo when, yes, it did hit 100 degrees. It was on April 21 1980. The ice was still on many of the nearby lakes in Minnesota that day which made for some interesting pictures of near 100 degrees and ice on the lakes at the same time. There has never been, since records began, a more wide spread hotter day in April. Fargo was not the only location to record a 100 degree temperatures plus most of North Dakota and northwestern Minnesota was at least 90 if not well into the 90s. It was a day that many remember as it was the earliest 100 by nearly 6 weeks.
