2007 was, on average, a ’normal’ year in the Red River Valley region. However, the term normal in meteorology can be a bit misleading, as extremes are what make up "normal weather". Below are some preliminary statistics for the calendar year 2007 for the Fargo and Grand Forks Airports, as well as the National Weather Service/University of North Dakota (NWS/UND) Climate Station.
Fargo Hector Field
2007 Average Maximum 53.1F Climatological Avg Max 51.6F Departure 1.5F
2007 Average Minimum 33.1F Climatological Avg Min 30.8F Departure 2.3F
2007 Mean temperature 43.1F Climatological Avg 41.2F Departure 1.9F
2007 Total 26.24 Climatological Normal 21.19 Departure 5.05
Grand Forks Airport
2007 Average Maximum 51.0F Climatological Avg Max 51.2F Departure -0.2F
2007 Average Minimum 29.2F Climatological Avg Min 29.5F Departure -0.3F
2007 Mean Temperature 40.1F Climatological Avg 40.4F Departure -0.3F
2007 Total 21.10 Climatological Normal 19.60 Departure 1.5
Grand Forks Climate Station (NWS/UND)
2007 Average Maximum 50.5F Climatological Avg 50.5F Departure 0.0F
2007 Average Minimum 30.9F Climatological Avg 28.8F Departure 2.1F
2007 Mean Temperature 40.7F Climatological Avg 39.8F Departure 0.9F
2007 Total 23.80 Climatological Normal 19.65 Departure 4.15
Please note the differences between the Grand Forks Airport and Grand Forks NWS/UND Climate station data. Significant variability can and does occur in temperature and precipitation data over fairly small areas. This variability may result from equipment locations, e.g. the Airport being in a more rural setting, while the NWS/UND location is more urban.

In many other ways it was a very "normal" year climatologically. The yearly total cooling degree days (CDD) were close to average in Grand Forks, with 480 CDD, only 60 above the average. In Fargo, the total was a bit higher, with 709 CDD, which were 212 above normal. There were 15 days when the temperature equaled or exceeded 90F in Grand Forks, which are just 3 above the long term average. In Fargo, it was warmer a bit more frequently. 20 days say the high temperature equal or exceed 90F, which is 6 days above the average.
On a more regional scale, the overall trend in 2007 was for less precipitation than the 1993 - 2000 wet period. While drought was not as significant an issue in 2007 as it was in 2006, drier than normal conditions in many areas were common. As a result, soil moisture was a bit below the longer term averages. Area rivers and streams were generally at or below normal flow values going into the winter freeze up.
Please remember the above information is very preliminary based on data collected by the NWS in Grand Forks. The final, official climatological information will be available from the National Climatic Data Center (NCDC) later this year.
