Heat Warnings & Weather History

posted in: Michigan Weather Forecast | 27

We have a very sultry 78° this morning with 97% humidity.  Like yesterday we have a large area of rain beginning to move across the lake along a stationary front draped across Wisconsin.  Like yesterday it appears to have another morning of state wide coverage with stronger cells in the northern lower.  So, I guess we have a morning rerun.  I believe most of the heavier rain will fall from Grand Rapids to the north.

Rainfall totals for Otsego were .20 of an inch  yesterday with a high of 86° around dinner time.  Today we expect highs of 90-95  with heat indices 105-110 south of I-96 and around 100 to the north with a repeat on Saturday.  Never fear there will be relief in the latter half of the weekend through next week.

We will have to keep an eye out for storms tonight (slight) and tomorrow night (probable).

We also have an Air Quality Alert for Muskegon, Ottawa, Kent, Allegan and Van Buren counties today.


Weather History

July 14

1950: Cold air filters into Michigan, setting records lows of 45 degrees at Grand Rapids and 41 degrees at Muskegon.

1974: Several tornadoes struck Lower Michigan during the afternoon, causing some structural damage but no injuries. In Mecosta County, a house and some farm buildings were damaged about four miles east of Sylvester. Apartment buildings were damaged near Plymouth, in Wayne County. Seven houses were destroyed and 50 damaged near Davison in Genesee County.

1995: An intense three day heat wave claims hundreds of lives across the Midwest, mostly elderly people in the greater Chicago area. The low temperature of 81 degrees at Grand Rapids on this day is the warmest low temperature ever recorded there. Temperatures in the upper 90s in the afternoon combined with high humidity to produce heat index readings near 120 degrees, some of the highest ever recorded.

July 15

1863: It was a frosty morning with temperatures falling to the 30s across much of Michigan. The low of 31 degrees is the coldest ever recorded in July at Lansing by a full five degrees.

1961: A heavy downpour hits Grand Rapids, with 0.41 inches of rain falling in 15 minutes.

1985: A tornado touched down in the northeast section of Lansing and damaged 18 buildings as it moved to three miles north of Webberville in Ingham County.

1987: It was the coolest July day on record at Grand Rapids, with a high of only 58 degrees. Clouds and rain kept temperatures in the upper 50s and lower 60s during the day after morning lows in the mid 40s.

July 16

1945: The second morning of record cool weather in five days produces low temperatures of 42 degrees at Grand Rapids and Muskegon.

1986: A plane carrying executives from Holland to Muskegon crashed while landing in heavy fog. The pilot had descended below approach minimums and the plane struck two trees about two miles short of the runway. Three people were killed, including the pilot. Three others were injured.

July 17

2006: A widespread severe weather outbreak struck West Michigan. Dozens of trees were downed by winds gusting between 60 and 70 mph. A camper was injured by a falling tree at a campground in Dorr, Allegan County. Two inch diameter hail fell at Marne in Ottawa County.

2009: The high of 67 degrees at Grand Rapids is a record cool high temperature for the date, and contributes to July, 2009 becoming the coolest July on record. The highest temperature for the entire month is only 84 degrees, the lowest monthly maximum temperature for any July on record.

1994: A small, short-lived tornado was observed lifting small debris at the Clare County airport north of Harrison.

July 18

1952: Thunderstorms with heavy downpours resulted in flooding of basements and some streets across West Michigan

July 19

1894: Temperatures reach 100 degrees across much of Michigan for the second day in a row. At Lansing, the high of 102 degrees ties the record for the all time hottest temperature.

2009: Cool and unstable air over Lake Michigan spawns at least two waterspouts. One of the waterspouts moves inland near Holland, just north of Lake Macatawa, but quickly dissipates and causes no damage.

July 20

1954: Severe thunderstorms produced golf ball-sized hail and damaging winds across West Michigan. In Kent, Ionia and Montcalm Counties, dozens of trees were felled and some crops were wiped out by the hail and high winds.

2003: A tornado with peak winds around 100 mph struck near Battle Creek. It left an 8 mile long damage path and tore a garage from a house. Three outbuildings and a barn were also destroyed. Hundreds of trees were uprooted or broken off. The tornado width was nearly one half mile wide where the most severe damage occurred.

Thunderstorm in progress here. I am not sure how strong the wind is but it is whipping out there. I felt it hit the house. Lots of rain.

According to radar estimates, we received more than an inch of rain in less than an hour. I believe it. There was plenty of ponding on the roads, yards and on the golf course.

Sadly back from out West already, only had 5 days because of our work schedules. Stepping out of the airport in GR and holy smokes! It was like we were being suffocated, what a smothering heat! After being in the mountains with temps in the 50’s and 60’s this is absolutely awful. Driving through Denver our car had a temp of 104, but the dew point was only 28. Way more tolerable than what is going on here. I can’t imagine it feeling any worse than this!

Interesting sign we saw yesterday for “dangerous snowfields”. Are there land mines present?

You are fortunate to be out west. It is soupy and miserable here.
