The Cool Summer is Nothing New

This summer has proven to be much cooler then average so far. All locations have failed to hit 100 degrees and many places across the far east have only hit 90 once or twice. Many South Dakota cities average 10 or more 90 degree days in the month of July alone. But this cool summer isn't something that just sprung up overnight. In fact, much of the upper Midwest has been on a cool streak for nearly the last two years. The chart below was just released from the National Weather Service and it proves just how cool its been.Over the last 21 months (including this one), Watertown has had 15 months below average, Pierre is at 16, and 19 of the last 21 months, Aberdeen has been below average. So how long is this going to last? Well, there hasn't been any signs of this pattern letting up and the Climate Prediction Center (CPC) agrees, not only in the short term but the long term as well. The next 8-14 days show high probabilities of staying below average and the next three months include much of eastern South Dakota in the below average category as well.
