We had a storm cell move through early this morning prompting warnings from the NWS. Lots of lightning, thunder, wind and rain. A Thunderstorm watch remains in effect until 9 am.
We had .80 of an inch of rain from the storm with an 18 mph wind gust which is pretty good seeing how we are in the middle of the wood in a valley. Further east in Plainwell they had a gust up to around 30 mph in the flatlands. Most of the rest of the state appears to have escaped the rain and severe weather.
Weather History for SW Michigan
1943: The USS Muskegon, named after the Michigan city, is launched from Superior, Wisconsin on a day with scattered showers and a high temperature of 86 degrees at Muskegon, Michigan. The ship saw duty in World War Two, escorting convoys across the Atlantic. The ship also took weather observations and served as a radio and lightship for trans-Atlantic flights until after the end of the war.
2005: An extended round of severe weather from the evening of July 25th into the morning of the 26th produced widespread wind damage across Lower Michigan. A tornado struck three miles west of Baldwin and downed hundreds of trees at a campground. Fortunately, most of the campers had left just hours earlier, and there were no injuries.
1896: A tornado struck a few miles northeast of Battle Creek, seriously injuring one person as it destroyed a farm home and barns in Pennfield Township, Calhoun County.
1973: A tornado damaged a mobile home and some farm wagons two miles southeast of Clare, Michigan.
1977: Canadian high pressure brings record cold temperatures of 46 degrees at Muskegon and 47 degrees at Grand Rapids.
1894: The temperature hit 100 degrees at Lansing during the second record heatwave of the month, the first of which occurred a week earlier when Lansing set its all-time record of 102 degrees
1955: Temperatures reached the upper 90s for the second day in a row across West Michigan in one of the hottest months on record. At Grand Rapids, 15 days had high temperatures above 90 degrees during July 1955.
2002: A severe weather outbreak produces tornado and downburst wind damage. A tornado with top winds around 80 mph touched down about one mile east of Augusta in Kalamazoo County. The tornado passed through Fort Custer in western Calhoun County, about one mile northwest of the Battle Creek airport. The damage path was approximately 800 yards wide and the path length was 3 miles long. Extensive tree damage occurred in the Fort Custer area and the roof was blown off a firing range shelter. After the tornado ended, downburst damage continued for several more miles in Calhoun County. A severe thunderstorm struck a campground and mobile home park along Swan Lake in southern Allegan County. Trees were blown down onto mobile homes and small boats were blown out of the lake. Two minor injuries occurred. Top winds with the downburst were estimated at 70 mph.
1959: A steady rain brought relief from drought conditions across West Michigan. Dry weather began in April, resulting in water rationing in Grand Rapids by the middle of July.
1976: A tornado injures five people northwest of Grand Rapids as it damages a warehouse.
1996: A weak, short-lived tornado damaged a pole barn near Evart in Osceola County.
1916: Temperatures soared to record highs as a ten-day heatwave reached its peak. The 102 degrees at Lansing would tie the record for the hottest day ever there. Grand Rapids hit 103 degrees as part of a record string of four consecutive days of 100 degrees or higher. Even the Lake Michigan shore was baking, with Muskegon hitting 95 degrees.
1913: Offshore winds negate the cooling effect of Lake Michigan as Muskegon hits 99 degrees for its all-time record high temperature. Temperatures are actually a bit lower inland as Grand Rapids is 96 degrees and Lansing 92 degrees.
1960: Two squall lines preceding a cold front produced widespread severe weather with high winds and hail. Severe crop damage from hail occurred across much of Kent County.
2008: A tornado struck about three miles north of Clare at 3:17 a.m. A barn collapsed and the roof of a carport was blown into a stand of trees. Several other trees were either snapped off or uprooted.
1883: Very heavy rains during June and July cause the Grand River to rise to unusually high summer levels. Lumber companies use the high water to float logs to a log boom upstream of Grand Rapids. The logs broke loose and crashed into the Detroit, Grand Haven & Milwaukee Railroad bridge creating a jam estimated at thirty feet deep and seven miles long. Sections of Grand Rapids were flooded by backwater. Eventually, the bridge gave way and several bridges downstream were damaged by the cascading logs.
1917: A heatwave produced record highs in the upper 90s as July ended, with Grand Rapids hitting 98 degrees and Lansing 96 degrees. There were also record high minimum temperatures of 79 degrees at Grand Rapids and 74 at Lansing.
2005: Hot and dry weather during the month leads to drought conditions along the Lake Michigan coast. Agricultural production was hampered as the dry conditions continue into August.
Weather History for SE Michigan
On July 25, 2017, the low temperature fell to 47 degrees, tying the record low temperature for the date originally set in 2013.
On July 25, 1986, Genesee county reported an F1 tornado at 5:05 pm that caused 1 injury and 25 thousand dollars in damages.
On July 26, 2012, training thunderstorms produced a band of torrential rainfall and some severe weather mainly north of the I-96 corridor. Despite strong winds downing some trees and power lines north of I-69, the main impact was heavy rainfall, including a 2-day (July 25-26) total swath of 1″ to 2″ across the Saginaw valley
On July 26, 2007, numerous reports of large hail occurred with storms that blew up in the very unstable air mass over Southeast Lower Michigan. The worst of these storms hit eastern Shiawassee County (around Durand) and further south in Lenawee and Monroe counties (in and around Adrian, Petersburg and Samaria). Hail up to the size of golf and ping-pong balls were seen in a few of the worst storms!
On July 27, 2014, an atmosphere ripe for the generation of large hail erupted over Southeast Michigan resulting in widespread severe weather. Numerous reports of wind damage and heavy rainfall were received. However, it was the significant hail that made this event unique. Hail reached 2.5 inches in diameter just north of Milford in Oakland County and 3 inches (larger than a baseball) in Bay County.
Also on July 27, 1928, 3.07 inches of rainfall fell in Saginaw. This is the precipitation record for the month of July in Saginaw and is also greater than the average amount of precipitation Saginaw receives for the entire month of July (2.50 inches)! Also in 2004, temperatures hovered in the mid-50s to 60s as a steady rain fell. The record low maximum of 64 (which occurred just after midnight) broke the old record of 70 degrees set back in 1874.
On July 28, 2011, intense thunderstorm rain from about 2 a.m. to noon, led to rainfall totals of 3 to 7 inches which lead to flash flooding across Shiawassee, Genesee, Livingston, Oakland, Washtenaw and Wayne Counties. Some of the heavier rainfall totals included 5.5 inches in Goodrich, 6.26 inches in Ypsilanti, 6.5 inches in Chelsea.
On July 28, 2010, severe thunderstorms developed over Metro Detroit. Among the 15 wind and wind damage reports was a measured wind gust to 73 mph at Selfridge ANGB.
On July 29, 2000, thunderstorms brought flash flooding to Detroit. Rain amounts were 2.92 inches of rain.
On July 30, 2000, 1.12 inches of rainfall fell in Flint, which is the precipitation record for the day. This marked the third day in a row (July 28-30) that daily precipitation records were recorded for Flint. The grand total for rainfall for this three-day period was 6.03 inches – this is almost twice the normal monthly precipitation (3.17 inches)!
On July 31, 1925, the greatest rainfall for a calendar date in Detroit occurred on this date when 4.74″ fell. Also, back in 1891, this date marked the end of the coldest July ever recorded in Detroit, with a mean temperature of only 67.2 degrees, well over six degrees below the current norm!
- Storms move out this morning The threat for strong to severe storms is now mostly for the counties south and west of Grand Rapids. The rest of the area, will see showers and thunderstorms ending from north to south over the next few hours. Most area should be dry by 9 to 10 am. In those areas strong to severe storms are very unlikely. The primary thunderstorm complex has dropped south to southern Wisconsin and with the best instability south of that line, it does seem greatest threat is now west of Lower Michigan. Still the low level jet does develop eastward from Wisconsin into Lower Michigan by 7 am, near I-94. The 1000/850 moisture transport vectors increase and move into our SW CWA by sunrise. So, given the mix layer cape is still expected to be near 2000 j/kg near I-94 west of US-131 and all the other factors, it seems reasonable to believe strong to severe storms are still possible in that area. Once the convection is south of this area (mid to late morning) we should see decreasing clouds and lower dew points. The real push of cooler air comes in tonight when a secondary cold front comes through the area. Skies should be mostly clear. - Cooler Friday The surface high moves in to our area as the polar jet continues to deepen over the eastern CONUS. 850 temperatures fall to between 5 and 10C, which is the coolest it has been since late June. This will result in mostly sunny skies with highs only in the 70s. - Showers/thunderstorms later Saturday into Sunday A strongly digging northern stream shortwave moves into this area by later Saturday and that even farther deepens the eastern trough. That shortwave will have cold front associated with it and will have just enough moisture and instability for some scattered showers and thunderstorms. That will mostly be late Saturday into midday Sunday. - Cool into midweek As I have been writing about for most of this past week, the eastern trough will remain in place through at least the middle of next week. That will mean cooler temperatures into Wednesday. Once we get past Sunday I expect mostly dry weather through most of next week.
