Weather Talk: Last Wednesday saw big temperature swingThis past Wednesday, the low at the Grand Forks Airport was minus 17 degrees. Later in the day, a strong surge of mild Pacific air moved across the Red River Valley, which pushed the temperature to 39 degrees during the early evening hours. That 39-degree high was a record for the date.
That difference from morning low to afternoon high was an impressive 56 degrees (Fargo rose 45 degrees that day). Grand Forks carries two weather data sets: one from the airport going back to 1941 and the other from the University of North Dakota (and now the National Weather Service) that goes back to 1890. I did not have the airport data set handy, but using the UND data set, that 56-degree temperature change would be the second-highest observed, behind a 57-degree swing on April 28, 1926 (20 degrees to 77 degrees).
This area is known for quick changes in the weather, but even by our standards, Wednesday was definitely a day to remember.
