The first half of 2010 was a significant turnaround from what we experienced the past two years. Both 2008 and 2009 started cool with temperatures during the first six months of both years ending around 3 degrees below the long-term average. Whereas, the first six months of this year the average temperature was 3.6 degrees above normal.
Most of that positive temperature anomaly was courtesy of the very mild period during March and April, but every month this year, except February, has finished at least slightly above average. This stretch of warmer air is also notable in that it was the longest stretch of above average temperatures such 2006 as the past three years has been noticeably cooler than normal.
Although 2010 is starting differently than the past two years for temperatures, it has not been for rainfall. This year is our third straight with above average precipitation during the first half of the year, but unlike 2008 and 2009, none of the months were excessive wet. Plus, most of Fargo and Moorhead was missed by the narrow heavier rain event from June 17, so although, the official rain total for Fargo Moorhead is 2 inches above average, most of the city is actually almost exactly at the average for this time of year. A rarity in our climate.
