Weather History for SE Michigan
On December 25, 2000, Christmas morning dawned clear and frigid, with a morning low of 13 degrees below zero at Flint, setting an all-time mark for the month of December (the old record was -12 on Dec 23, 1989). Saginaw reached 3 degrees below zero. Three nights later, Flint would give the new record a run for its money, coming up just short with a low of -11 on the 28th (this was still a new record for the day). Saginaw fell to 5 below zero on the 28th. The arctic weather would take a toll on pipes. Both Ypsilanti High School and Chelsea High School had pipes burst over Christmas weekend, damaging classrooms. Several buildings on the University of Michigan campus in Ann Arbor had similar ruptures, including the School of Dentistry and Wolverine Tower. The cold also hampered shipping interests. Ice formation was extremely rapid on the Great Lakes and the connecting waterways. Several freighters got stuck in ice on both the Detroit River and Lake St Clair, blocking the shipping channel and bringing dozens of ships to a halt. Icebreaker assistance was needed to free the freighters. This arctic outbreak helped to seal December 2000 into the records with the 4th coldest December in Detroit, and the second coldest December for both Flint and Saginaw.
Also on December 25, 1982, record daily high temperatures of 64, 65, and 63 degrees were respectively set in Detroit, Flint, and Saginaw. This made for a record-warm Christmas Day in 1982! Curiously enough, the very next year in 1983, the record low for Christmas was set with -10 at Detroit!
On December 26, 2016, Detroit, Flint, and Saginaw set record highs of 57, 56, and 54 respectively.
Also on December 26, 2012, a large Gulf low lifted northeast along the Appalachian Mountains and clipped southeast Michigan bringing a widespread accumulating snowfall to the area. By the following morning, 4″ to 7″ had accumulated across the southeast half of the area, with higher amounts of 14″ in Lakeport and 11.1″ in Port Huron. Detroit and Flint measured storm total accumulations of 6.2″ and 5″ respectively. Further northwest, Saginaw received a glancing blow and measured only 1.5″.
Also on December 26, 1914, the overnight temperature plummeted to -12 degrees in Saginaw, which is 30 degrees below the average overnight temperature!
On December 27, 1904, there was a maximum temperature of 56 degrees in Detroit between 3 and 4 pm that fell steadily to a minimum of 18 by midnight.
On December 28, 2008, a rapidly intensifying storm system moved across Lake Michigan to the Straits area. This storm brought wind gusts up to 60 mph to all of Southeast Michigan, and wind gusts up to over 70 mph to Lakes Huron, Erie, and St. Clair. Numerous trees, limbs, and power lines were down. In all, about 300,000 customers in Southeast Michigan lost power during the height of the winds.
Also on December 28, 1880, the daytime temperature rose to only 4 degrees in Detroit, which is 29 degrees below average!
On December 29, 1998, 0.1 inch of snow fell in Detroit. While this light snowfall is not usually a significant event at the end of December, this was the first measurable snowfall for the 1998-1999 winter season, making this date the latest first measurable snowfall of any winter season.
Also on December 29, 1880, the daytime temperature rose to only -3 degrees in Detroit. This is the second coldest maximum temperature for any day in Detroit!
On December 30, 1971, Detroit recorded the greatest amount of precipitation in 24 hours for the year. The recorded measurement was 1.37 inches.
On December 31, 2015, the high temperature reached 36, 34, and 33 in Detroit, Flint, and Saginaw respectively. Although typical for December, they were chilly compared to the rest of the month. Fueled by a particularly strong el Nino and a northward displacement of the polar jet stream, the monthly average temperature for December 2015 came out to 41.1, 40.0, and 39.1 degrees, making it the warmest December on record for all SE Michigan climate sites.
Also on December 31, 1974, marks the end of the snowiest December on record in Detroit. A total of 34.9″ of snowfall fell during the month, which is 23.8″ above average!
- Thawing Out With Light Rain and Fog Moving In Low level moisture below 5000 ft will advect in ahead of the western U.S. upper level trough late tonight into Thursday. Model soundings show low cloud cover developing region wide during that period. Light rain or drizzle should develop ahead of the surface cold front that is forecast to be moving across central Iowa by 00z Friday. As abundant low level moisture moves overhead Thursday, light fog should develop but could get locally dense over areas with a sizable snow pack. This could make for some highly variable visibilities across the region and some difficult driving conditions at times. The 00z model suite continues to tone down rain amounts Thursday into Friday. There is still both deterministic and ensemble guidance spread in QPF for late Friday into Saturday. The current thinking is that the cold front should move into SE Lower MI Friday afternoon and stall out there. That part of the state will be more susceptible to receiving additional rainfall Friday night into Saturday as another mid level shortwave pivots through. LLJ orientation does not look favorable for our area on the 00z ECMWF while the GFS is further west and wetter. The 00z WPC QPF shows the area at greatest risk for 0.25" or greater to be near/east of I-69. Sunday is trending drier region-wide. There is a risk for mixed precipitation Friday night into Saturday night across central Lower MI as surface temps drop into the low to mid 30s. Some light freezing rain and/or snow would be possible. This is more likely to occur Saturday night based on model soundings. - Another Surge of Warmth Early Next Week With Rain Ensemble guidance is narrowing in on a storm system slated to impact the region late Monday into Tuesday. The upper level pattern looks more dynamic with this system than the one moving through late this week. A deep upper low should develop west of the Great Lakes, placing our area well into the warm sector. This is shown by a consensus of deterministic and ensemble guidance bringing 850 mb temperatures into the 7C-10C range. Vigorous LLJ development ahead of this upper low is forecast with 50-60 kts advecting in Gulf of Mexico moisture into the Great Lakes. Heavier rainfall is possible with this system (0.50" or greater). Additionally, depending on warm frontal placement, some elevated instability may develop and we may need to include a risk for some thunderstorms if trends continue. Ensemble mean high temperatures are now inching into the mid 50s on Tuesday for southern Lower Michigan, with a notable number of members from the ECE/GEFS/CMC showing 60s reaching areas south of I- 96. These kinds of temperatures would threaten records for January 3. Whatever might be left of our snowpack early next week will be torched with this system when you factor in both the rainfall and temperatures. At this point, snow melt combined with rainfall over the next 7 days does not appear to rise to the level of any river flooding, but we will have to monitor ice movement over the next few days for the potential for ice jams forming. Currently, our river modeling shows low potential for break-up ice jams to occur even with the rain and warmer temperatures. Still, something to keep an eye on for our jam- prone locations. - Seasonable Winter Temperatures Return Mid to Late Next Week Ensemble guidance brings in more typical wintertime temperatures after this warm system departs the region early next week. Highs should return to the 30s with lows in the 20s. Some light lake effect snow showers may be possible next Wednesday.
The iPhone weather app shows 60 for next Tuesday… that would be crazy!
The record high for January 3rd is 59 set in 2004 even 50 would be the 5th warmest for the date.
5 daily snowfall records being broke sofar this Wimter season is amazing wow to the wow …INDY
Interesting choice of words in the above forecast discussion for the upcoming extended December/January thaw. “Risk of thunderstorms”, the snow pack being “torched”, possible record highs in the “60’s”. Pretty wild swings in our weather. Bottom line, no matter how much snow may have fallen in some areas, it will all be reset back to zero on the ground.
We are at 34 degrees here currently. Finally done with the 20s (even for lows) for the next 7-10 days. I always enjoy early January thaws. I’m sure we will cool back down around the middle of the month again
Grand Rapids Michigan 2nd most snowest city in America the records keep Being broke this Wimter season amazing…..INDY
It has been an absolutely incredible start to winter! Will we beat 100 inches for the season? Amazing storm and an amazing winter so far! Keep it rocking after this brief warm up!
I’m guessing Buffalo is #1? The footage from there is unreal. Did you see the clip of the Bills players digging out their vehicles after returning from their road game? The one dude drives away with a glacier on top:
Yes Buffalo is number 1 as thsese are citys with a 100 thousand or more people living in them but pretty amazing record…INDY
Well, we had a whopping 2-3 days to enjoy the fresh snow. It starts to get mushy and melty today.
Talking about mid 50’s and 60’s in January now. Wow!
Good Morning! The official H/L yesterday at Grand Rapids was 26/16. It looks like yesterday will be the last day with highs below 32 for some time. There was just a trace of snow fall yesterday and for season GR has 67.6” and for December 39.6” these totals should stay the same for some time with the warm temperatures. There was 26% of possible sunshine yesterday. The current temperature in MBY is 24. I have 13” of snow still on the ground but that will be going down the rest of this week and into next week. For today the… Read more »
As I stated, the record high for today of 65 was set in 1984. I remember that day. I was transferred to GR in April of 1984 the winter of 1984/85 was the first winter for me in west Michigan. And I remember the night of December 28 and the overnight as well. Late in the day of the 28th a warm front came thru and the temperatures shot up to that 65 after sunset. And it was a warm windy night and there were thunderstorms as well. There may have been a storm warning that night. I see in… Read more »
