Very hot July in SE Minnesota - 4th warmest on record & Warmest on record averaged low on record for Rochester Airport

July 2012 was a very hot one in SE Minnesota. The hottest since the 1950s! Most days were in the upper 80s to lower 90s across the region. With lows commonly in the 60s and 70s. The highest area wide temperatures this month occurred at Red Wing and Winona both with highs of 102.F. A hot ridge of high pressure centered over the midwest was the reasoning for the hot July. Precipation was generally below average at most locations. For this report I will focus on temperatures at Rochester Airport becuase it has the longest history.
