The NWS Grand Rapids radar (KGRR) went offline yesterday during the storms (an inopportune time) and is still offline this morning. I had to use the KLOT Chicago and KAPX Gaylord radars for storm tracking. I use Radarscope Pro.
Below is the NWS summary of the storm damage:
We had some thunder and lightning in the Otsego area and some brief gusts of winds but only managed .10 of an inch of rain which brings us to .15 for the month. Yesterday’s high was 84° with a low of 52°.
Sunrise today is 7:16, sunset is 8:04 pm.
Weather History for SW Michigan
1997: Cool weather prevailed with scattered frost and a record low of 34 degrees at Lansing.
1881: Temperatures hit the mid and upper 90s as a four-day heatwave peaked across Lower Michigan. Lansing reached 97 degrees for their second record high in a row, both records that still stand.
1960: A three-day heatwave peaked with record highs of 96 at Grand Rapids and 94 at Lansing.
2001: Severe thunderstorms produced widespread wind damage. About a dozen trees and several telephone poles were blown down in Saranac in Ionia County.
1874: One of the longest heatwaves in the month of September is underway with Lansing hitting 95 degrees. Lansing would have eight consecutive days with high temperatures in the 90s from September 7th to the 14th.
1951: A cool air mass settled into Lower Michigan bringing frost and freezing temperatures. Grand Rapids fell to a record low of 31 degrees.
1968: A tornado injures one person as it damages several businesses in Cedar Springs in Kent County. Another tornado damages a farm west of Monroe, Michigan.
2001: A tornado moved through Delta Township and into the western outskirts of Lansing causing heavy damage over an eight-mile-long path. There were minor injuries and several barns and other buildings were damaged or destroyed.
1917: High temperatures were only in the middle 50s as cool and cloudy conditions prevailed.
1931: A record high of 94 degrees was set at Grand Rapids, contributing to the warmest September on record there.
1943: The USS Grand Rapids is launched from Superior, Wisconsin. The weather in Grand Rapids, Michigan is cool with a low of 39 degrees. The ship was outfitted to take weather observations but was damaged by a hurricane as it sailed towards Bermuda. It was repaired and provided vital weather observations in the North Atlantic through the end of World War Two.
1946: A weak tornado hit near Albion in Calhoun County around 730 AM, with damage limited to several downed trees.
1986: Clusters of thunderstorms moving along a stalled front bring record rains to Lower Michigan for the second straight day. Widespread rainfall amounts of 2 to 5 inches result in extreme flooding and contribute to making September 1986 the wettest month on record across the area.
2013: A severe thunderstorm with wind gusts of up to 80 mph brought down numerous trees and power lines in Albion, Michigan. Albion College was closed for several days due to all the wind damage and loss of power.
Weather History for SE Michigan
On September 5, 1984, Detroit experienced a record low of 42 degrees. This was the first of 2 consecutive days to experience a record low. On the 6th, the temperature dropped to 38 degrees.
On September 6, 1990, rush hour traffic came to a halt when an F1 tornado hit St. Clair County at 5:20 PM.
On September 7, 2010, winds gusted between 40 and 50 mph across Southeast Michigan, with the strongest winds occurring over the Detroit Metro area. A few trees and tree branches were blown down, some of which fell onto power lines. Very low humidity levels, less than 25 percent, allowed the sparking wires to touch off fires across Wayne County. The wind-swept fires destroyed 90 occupied homes and damaged 71 vacant homes and garages. No injuries were reported.
Also on September 7, 2001, Livonia experienced winds of 58 mph with a thunderstorm at 4:55 pm. Chesaning and Buena Vista also experienced winds with this storm which gusted up to 63 mph.
On September 8, 1997, a waterspout was sighted over western Lake Erie. It was located offshore from Bolles Harbor which is just south of Monroe.
On September 9, 2001, a cold front finally passed through Southeast Michigan ending an unusual three-day severe weather outbreak in September. The cold front slowly approached the western Great Lakes region on the 7th and 8th while warm and unstable air ahead of this front allowed thunderstorms to develop during the afternoon and evening hours on all three days. Most of the thunderstorms that developed over this three-day period produced severe wind gusts. The most common type of damage from these storms was trees being blown down or broken.
On September 9, 1931, the temperature rose to 98 degrees in Saginaw, which is the record high temperature for the day. This day also marked the beginning of a four-day period (September 9-12) of record high temperatures!
On September 10, 2017, Flint tied the record low of 36 degrees last reached in 1969. This was the 3rd day of reaching or exceeding record lows in the first 10 days of September.
On September 10, 2002, a strong cold front moved through eastern Michigan during the afternoon. Due to the drought conditions that year, the thunderstorms resemble those of the high plains with high cloud bases, less rainfall and strong winds. Hundreds of power outages were blamed on these thunderstorms. The more widespread tree damage in eastern Michigan occurred across portions of Shiawassee, Huron and Livingston counties.
Also on September 10, 1950, a record 6.04 inches of rain fell in Flint. The yearly precipitation average in Flint is 24.44 inches. In one day, Flint received nearly a quarter of its yearly precipitation average!
On September 11, 2000, widespread, severe urban flooding resulted in a Presidential Disaster Declaration for Wayne County. The communities most severely affected included Allen Park, Dearborn, Dearborn Heights, Ecorse, Lincoln Park, Melvindale, Riverview, Southgate, Taylor, Van Buren Township, Wyandotte, and Wayne. Over 15,000 residences and other structures in Wayne County suffered at least some flood damage. Numerous motorists had to be rescued from their stalled and stranded vehicles. The Governor of Michigan estimated $19 million in personal property damage in Wayne County but said that estimate was conservative.
Also on September 11, 1986, Saginaw received 4.55 inches of rainfall. The previous day (September 10, 1986), Saginaw had received 5.51 inches of rainfall. This makes a two-day total of 10.06 inches of rainfall in Saginaw – almost three times the amount of rainfall that Saginaw normally receives throughout the entire month!
- A few showers/storms later today into this evening Deep cyclonic flow persists today. A weak shortwave and associated surface front tracks through as well...mainly this afternoon and evening. Water vapor imagery shows this vort max dropping southeast through MN at this time. Guidance has been showing weak instability developing as well. All this could support a few showers and thunderstorms. We will maintain this in the forecast. Any precipitation should be brief. - Cooler than normal pattern next few days Warm air advection does not develop until later Friday. Until then...a cooler airmass will be in place. Some lake effect clouds and perhaps a few spotty showers could develop Thursday. Models are showing the low level thermal trough shifting eastward through the CWA on Thursday. Normals for this time of the year around Grand Rapids are around 77/56. Current projections have us running 4 to 7 degrees below that for the next couple of days. - Warming up over the weekend Warm air advection strengthens Friday night into Saturday. The temperature at 850 mb is shown to rise into the teens for the weekend. This will allow for surface temps to rise back into the 80s with some heating. There is a weak front that tries to drop down from the north on Sunday. At this time it looks like that feature will be weakening and thus its influence on the surface temps may be limited and/or temporary.
