muskegon glerl screen grab  chicago glerl This is a screen grab from the Muskegon GLERL camera showing a couple of people out at the end of the breakwater in the rain, and a screen grab from the Chicago GLERL camera, showing the top of the Sears…no now it’s the Willis Tower disappearing into the low stratocumulus clouds.  High temperatures today:  73 Lansing, 71 Battle Creek and Grand Rapids, 70 Kalamazoo, 67 Holland and 66 in Muskegon.  The afternoon high temperature at the GLERL thermometer on the S. Haven Lighthouse never got warmer than 56 and the Muskegon beach GLERL thermometer peaked during the afternoon at 58.   The 71 in G.R. was the coolest high temperature in July since 7/19/2009.  July 2009 was the coolest July ever in G.R. with an average temperature (average of the 31 high temperatures and 31 low temperatures) of 67.1.  The four coolest Julys have all come relatively recently, in 2009, 1992, 1996 and 2006.   The warmest July ever was 1921 with an average temperature of 79.8.  The warmest two days in G.R. were July 12-13, 1936, with highs of 106 and 108.   The coolest high temperature in Michigan today was 58 at the Marquette Coast Guard Station.  Copper Harbor wasn’t far behind at 60.  Other highs today:  62 Gay (in the U.P.), 62 Benton Harbor, 65 Fremont, South Haven and Munising, 67 Rogers City, 68 Three Rivers and 69 in Big Rapids and Cheboygan.  The water temperature of Lake Michigan is cold, too:  54 Hollmaster State Park, 55 Grand Haven, 56 Muskegon and Pentwater (we get upwelling with an east wind – it pushes relatively warmer water toward mid-lake, bringing colder water from well below the surface to the shore.   The beach air temperature in Chicago at mid-afternoon was only 60 and the beach temperature at Milwaukee at mid-afternoon was 61.

Here’s something interesting…it’s been hot and dry in Arizona, where humidities have been running as low as 5-10% in the afternoon.  Some thunderstorms formed today over the North Central Mountains.  Flagstaff got 1.74″ of rain, but get this…their temperature dropped from 86 to 50 as the storm came through.  Same thing at Saint Johns, Arizona, where a thunderstorm knocked their temperature down from 95 to 63.   Some other cool afternoon high temperatures today:  57 Grand Marais MN, 59 Bangor ME, 63 Farmington MO and Portland ME, 64 South Bend IN, 65 St. Louis MO, 67 Kankakee  IL, 68 Chicago and Mattoon IL, 69 Milwaukee WI and Lafayette IN.

    You state ‘The four coolest Julys have all come relatively recently’ but only mention the 1 hottest. Care to disclose the other 3? Let me guess … 2012 is one of them.

    1. Bill Steffen says:

      Sure…2012 was 2nd, 3rd was 1955, 4th was 1916, 5th was 1901, 6th was 1936. Also, the coolest August ever in G.R. was 1992, the warmest was 1947. The five warmest Augusts and the five warmest Septembers were all before 1960.

  4. arcturus says:

    Since the focus has been on the cool weather of late (ignoring the West) with cherry picking going back to 1992, it should also be known that every year of the decade except 2008 was among the 10 warmest on record.

    Just to put things in a little better perspective.

      I have several threads on the warm weather out West. Why should the Western heat get 100% of the media attention (Death Valley has fallen well short of the 134 degree record set 100 years ago) and not a mention of the coolest July weather EVER in Central Texas? I was referring to Grand Rapids, where all four of the coldest Julys have occurred since 1992. It’s the center of my viewing area, I should mention G.R. once in a while and I think the cool years coming recently is interesting.

      The truth is global temperatures have been flat for 11 years: http://data.giss.nasa.gov/gistemp/graphs_v3/Fig.C.gif

    Not sure what’s more interesting, the graphics or the comments.

    Temperature anomalies over the past decade …

      Note that the base average on the maps is either 1961-90 or 1971-2000. There would be more blue if the current, official 1981-2010 base normals were used: http://www.ncdc.noaa.gov/oa/climate/normals/usnormals.html or if you used say 1921-1950. (Or why not use the Medieval Warm Period!)

      Look at the historical record of the PDO (Pacific Decadal Oscillation: http://image.sciencenet.cn/album/201204/01/1048108jmuhu3hqcmmm843.jpg and the AMO (Atlantic Multidecadal Oscillation: http://cdn.physorg.com/newman/gfx/news/hires/2012/672px-amo_timeseries_1856-present.jpg When the PDO and AMO were both cool, the globe had its two coolest modern age decades in the 60s and 70s. They went to the warm phase and global temperature went up (which was well predicted by Dr. William Gray, when all the climate alarmists were forecasting a global cooling disaster (same solution…higher taxes into the general fund, more regulation and less freedom). http://www.populartechnology.net/2013/02/the-1970s-global-cooling-alarmism.html

      Now the PDO is in cool phase and the AMO is warm phase – global temperatures have been steady for a decade (no one disputes that fact). What happens when the AMO goes to the cool phase?

    While the airport did get to 71° (for a very brief period) here at my house (I, along with most other people do not live at the airport) only had a high yesterday (7/2/13) of 68° so all in all a very cool July day. Getting some hazy sun here now and a warmer but still cool by July standards 72° here now. Who knows this may be one of those summers where we do not reach 90° or better but its still too early to say that for sure.
    Now while its hot in the west its on the cooler side here in the east. (Wow like that never has happened before.) Most times if its hot to the west it will be cooler here and if its cool to the west it warm here!
