Weather Talk: Fargo officially reached 80-degree mark TuesdayEarly Tuesday evening, the temperature sensor at Hector International Airport in Fargo officially reached 80 degrees. This was the first 80- degree temperature of the year and the first since Oct. 2, 2012.
In 2012, the first 80-degree temperature did not occur until May 10. This is a fantastic illustration of how persistent snow cover delays spring temperatures. In 2012, the snow was gone March 12, the first 70-degree day happened on March 16, and then there were 17 more days in the 70s by today’s date.
This year, snow cover persisted through April 25, and the first 70-degree day was on April 27. The first 80-degree day in both years happened just three days apart.
It is virtually impossible for the temperature to hit 70 or 80 degrees with snow on the ground because of the way snow reflects sunlight. But once the snow is gone, spring weather can begin.
