Warmest Days of July

July 21st, 2014 at 1:56 am by under Bill's Blog, Weather

Rainfall U.S.   rainfall july 1-20 Click on the images to enlarge.  On the left, we have rainfall for the U.S. from July 1-20 (data not available for the grayed out area in the Pacific NW).  On the right, we have rainfall for Michigan for July 1-20.  Note now there has been less rain north of Muskegon and also closer to the Indiana border.  Grand Rapids has picked up 9.47″ of rain since June 1.  The MAWN agricultural weather station at Ludington has had only 0.57″ of rain so far this month, while Grand Rapids has had 4.32″ and Ithaca has picked up 4.7″.  Nationally, it’s still dry in California.  There has been a lot of rain along the East Coast, in Florida and in the Lower Mississippi Valley.

Temperature departures from average for July 1-20:  Grand Rapids -4.3° (highest 83°), Muskegon -4.9° (highest 81°), Ludington -6.9° (Ludington’s highest temperature for July 1-20 was 77° and they had 6 days with highs only in the 60s).  Cadillac -6.4° (five days in a row from July 16-20 with low temps. in the 40s), Manistee -7.4°, Gaylord -6.1°, Pellston -4.4°, Marquette -3.5° (including a high of 53° on July 15th!), Holland -4.6°, Lansing -4.5°, Kalamazoo -5.1°, Detroit -3.5°, Howell -3.8°, Ann Arbor -4.2°.      The average temperature for July 1-20 for Grand Rapids is 68.2° – if were were to end the month with an average of 68.2°, it would tie for 3rd coolest July ever in G.R.   The four coolest Julys in G.R. have all been relatively recent (2009, 1992, 1996, 2000).   July 20 BTW, is the mid-point of temperature for the summer.  Average temperatures from this point go down.   We have already lost 27 minutes of daylight since the Summer Solstice back on June 21.

Today and Tuesday will be the warmest days of the month of July – best days of the month to spend at the beach, pool or water park.  It gets cool for the last week of July.  The overnight run of the NAM gives G.R. highs of 85° Monday and 88° Tues. and the GFS is similar with 86°/88°.  I’ve got out 86°/90°.   The showers/t-storms may not move in until after sunset Tues. evening…and any leftover showers should end by mid-aftn. on Weds., so you may be able to get in evening activities each of the next five days…maybe.  The timetable for showers/storms will be Tues. after sunset thru midday Weds. and again next weekend.

The sky has been a little hazy and that’s partially due to a thin layer of smoke from wildfires in the western U.S. and in Canada.  It gives the sun an orange tint at sunrise and sunset.  Cooler temperatures and the prospect of some showers will help firefighters in Washington and Oregon.  The Buzzard Complex fires in Oregon have consumed 369,000 acres.  The Carlton Complex fire (impressive pic. at link) in Central Washington has burned 300,000 acres and 85 structures worth 3.7 million dollars.  There are 1,388 firefighters, 133 engines and 11 helicopters fighting that fire.  Despite those two big fires, the U.S. is below average in both the number of wildfires and the number of acres burned so far this year.  Last year we had the fewest number of wildfires since 1984 and the 2nd lowest number of acres burned in the last 10 years.

Sunday marked the 13th consecutive day of at or below normal high temperatures for Chicago…Downtown Sacramento records 0.01″ of rain, breaking a 75 day rain-free streak and setting a daily record…Heavy rain reported near Columbia, SC earlier this eve. 3.39″ fell in one hour, 1.53″ in 15 minutes… flash flooding in the Reno, NV area, multiple roadways closed…Spotter reported 1.10″ of rain in under 30 minutes in Gardnerville, NV, 16 miles from Carson City…Dallas tied its record low of 65 F Sunday a.m., third-straight day of record cool air…the remains of Tropical Storm Wali has produced some local flooding and minor wind damage in Hawaii.   Rainfall included 2.51″ at Hilo and 0.97″ at Honolulu.  There were four weather stations on windward Oahu that had over 13″ of rain in 24 hours!

This is an awfully long post already, but I read something interesting at CapCon…”Hemlock Semiconductor (near Saginaw) is a joint venture of Dow Corning, Shin-Elsu Handotai Company and Mitsubishi. It produces polycrystalline silicon, which is used for solar panels and electronic devices.  The company is the largest electricity customer at a single site in Michigan. According to Hemlock, at full production, it uses about 420 megawatts of electricity, which is estimated to be three times the electricity used by all of the households in Lansing and Ann Arbor combined.”     Three times the electricity used by all the households in Lansing and Ann Arbor combined??!!   That’s shocking!!

    Hopefully it hits 90 this week with some Humidity. Just bought a window A/C unit and would like to give it a try. Pretty sure it will cool my bedroom but if not i will take it back. Won’t be able to next year if it cant cool room down in Hot weather.Don’t really see any more Hot days this summer.

  9. SlimJim NW GR (1) says:

    The next two days look to be the warmest two days of this cool July. And I see that for some reason that Flint continues to be one of the few reporting stations that is less below average then the stations around it. One has to wonder if there is a accuracy issue over at that station! That could be the reason that one of the blogers uses that site as his “home” I have no issue with that blogers post its just there are times I wonder just where he lives. As I know people who live in his area and none of them claim to live in either Flint nor Detroit. Also here is some information for the GR NWS on this summer not have had a 90° yet this summer.


    I am surprised that GR has only had one summer where it has not gotten to 90 or better

    1. Rocky (Rockford) says:

      Flint is global warming central! None of their data should be trusted or even refereed to! Horribly in accurate! They are worse than WhateverTrends :)

    2. Mark (East Lansing) says:

      Flint’s reporting station is always way different than the surrounding areas. That’s why no one takes them seriously.

    3. Travis (Oakland County) says:

      Nothing wrong with the Flint station’s reporting as it’s always colder in Flint than Detroit or other areas for any given month 95% of the time.

      If you’re arguing against its long-term average, then you would have to take that up with NWS.

      1. Mark (East Lansing) says:

        Nah, I’d rather just discount it as inaccurate, untrustworthy, and unreliable.

      2. Rocky (Rockford) says:

        You have got to be kidding me! You are 100% delusional! Amazing!
