A deep low pressure area centered over Thunder Bay on July 10 dragged a strong cold front across Minnesota. Behind this front were some very gusty non-thunderstorm winds, more typical for April or may than July. Some peak wind gusts were 43 mph at both the Twin Cities and St. Cloud, 60 mph at the Duluth Airport, and 61mph at Fargo. Moorhead had one of the highest wind gusts in Minnesota with 66mph. There were 20,000 power outages in Duluth, sending many flocking to restaurants in town that still had their lights on. Just about all the outages were caused by trees falling on power lines. Falling trees also cut power in Fargo as well. Along with the winds, much cooler and drier air swept across Minnesota and put an end to the muggy 80's and 90's.
