Last Thursday, April 23, Fargo Moorhead recorded the first 70 degree day of the season. The long term average for the first 70 is on April 18, so even with the persistently cold weather this spring; we did manage to hit that milestone around the normal date.
But not only did we record our first 70 of the season last week, but also our first 80, as the official high on Thursday was 82 degrees. The average first 80 degree day of the season is on May 5, therefore earlier then the seasonal average. You may ask yourself, “how unusual is it to hit 80 without a previous day in the 70s”? 2009 was only the 11th time since 1881 that the first 70 degree day of the season happened to be a temperature of 80 degrees or higher. The last such occurrence was back in 1996 with a high of 83 degrees on May 15.
