      It Came Down in Buckets: July 2, 1992

      July 1, 1992: As a very chilly air mass held over eastern Canada, an energetic trough dug into the western U.S. Rain began in the U.P. that night.

      As July 1992 began, cool air that established itself after mid June remained entrenched over central Canada into the north-central United States. At the same time, a low-pressure trough drifted in off the Pacific. This trough spawned a storm that brought a heavy, pre-July 4th rainstorm to much of Upper Michigan (Image 1 above).

      It came down in buckets on July 2. Republic, in the central U.P., collected over 5.5 inches, while Bruce Crossing on the west end was inundated with 6.5 inches of rain. At the National Weather Service (NWS) near Negaunee, showers and thundershowers began the night of July 1st. It then rained more on than off into the 3rd with a total of over three-and-a-third inches. The system then lingered through the holiday, producing a cloudy, damp Fourth over most sections.

      I even heard a story from someone who swore they saw snowflakes in the high country of the western U.P. on July 4th (Why is July snow seen only on the Fourth?). It was chilly and miserable for the holiday, but the atmosphere was not cold enough to support snow. The official high at the NWS was 60 and the low was 45. Thatâ??s way to warm for snow in the cold season let alone the peak of the warm season when the lower layers of the atmosphere are reaching their warmest temperatures.

      Nonetheless, July 1992 started cold. The first week of the month had a mean temperature of 54.7 degrees, 9.4 degrees below average. July, the warmest summer month on average, did not live up to its billing in 1992. The month ended 6.2 degrees below average. It was the record coldest July at the NWS and at other sections of the Upper Midwest (Image 2).

      July 2013 has started cool. This morningâ??s low at the NWS was 38 degrees. Lows ran as cool as 34 in Champion and 32 at the southern Houghton County town of Kenton. An observer north of Ishpeming on North Camp Road reported frost with a low of 30! What a difference between this year and last. Last July, only one night even reached down into the 40s for lows at the NWS. This month has started much more like a typical U.P. July.
