Hector Int’l briefly dropped down to 34 degrees this morning. NDSU’s thermometer, part of their North Dakota Agricultural Weather Network, dropped to 38 degrees, the Moorhead Municipal Airport dropped to 37 degrees and our cooperative observer dropped to 38 degrees. So in other words, non of the "official" thermometers in town dropped to or below freezing this morning. This guarantees us a year without a frost in September.
About three out of four years the first frost in Fargo occurs in September, so this year is slightly later than the average. The latest first frost of the autumn season occurred on October 24th in 1994. I doubt we’ll be threatening that record this year, but it looks like we’ll have to wait until at least the 5th or 6th of October before we’ll have another threat of frost in the area.
