      Warming Up for the Warmest Month: June 26, 1921

      CPC gives the western U.S. the best chance of a hot July.

      On June 26, 1921, Stambaugh in Iron County recorded a sizzling record high of 97 degrees. Bergland in Ontonagon County also set a record with a 93-degree reading. This hot day occurred at the tail-end of the warmest June on record at the time. It was a mere warm up for what would be the warmest month on record set in July 1921.

      July 1921 was a hot one over the Upper Midwest (Image 1 above). The average temperature for the entire state of Wisconsin was 76 degreesâ??a record. In Marquette, the mean temperature hit 72.4â??over 7 degrees above average. From 1875 through 1978, this is by far, the warmest month on record. After 1978, the National Weather Service (NWS) moved â??up the hillâ?? to Negaunee Township. By way of comparison, the warmest July at that site is 70.1 set in 1983. Even last year with the consistent warmth and the hot start, July ended with a mean temperature of 69.2 degrees.

      Whatâ??s ahead for this July? Obviously, we will have our warm spells; the seventh month is the warmest one on average. However, it does appear we will start with a trough over or near the Great Lakes. That would mean near to below average readings through at least the Fourth. The Climate Prediction Center, a division of NOAA, is not certain one way or the other whether weâ??ll be warm or cool (Image 2). The â??ECâ?? covering the bulk of the eastern U.S. means â??Equal Chancesâ?? of above or below average temperatures.
