Our first heat wave of the summer is upon us. Temperatures are expected to reach to near 90 degrees Thursday, and then soar into the 90s Friday and Saturday. Although 90 degree heat is considered typical summer weather in many parts of the country, it is rare enough around here to be thought of as extreme by many people, even though it happens virtually every summer.
Most of our hot weather typically happens in July and August. In June, the average number of 90 degree days is just one and a half. Last year, there was one 90 degree day during June. In both 2014 and 2013, June passed by without any 90 degree weather. In 2012, there were two such days. Historically, many June months have gone by without any 90 degree weather but the average is skewed upward by the occasional summer with a June heat wave. The record number of 90 degree days in June is 13 days set in 1988. The record for a summer is 39, also set in 1988.
The Northern Plains region is not known for its hot weather. Cool breezes from central Canada often keep the heat from building in for more than the occasional hot day. However, we are located in the center of the North American continent and are entirely land locked, unaffected by cool ocean waters, and so our weather is prone to go to extremes. There are no solid barriers keeping all the hot weather in the south. So when it gets hot, it can get very hot.
