Weather History
1941: Lower Michigan is in the midst of a three day spell of mild weather with highs in the 50s from the 22nd to the 24th. The high temperature at Muskegon on this date is a record 54 degrees.
1989: Temperatures fall to record lows of 5 below zero at Muskegon and 11 below at Grand Rapids during the coldest December on record at both sites.
On December 23, 2022, Detroit’s temperatures plummeted from 40 degrees just before midnight to 1 degree at 10 a.m. in the wake of a blast of arctic air. Gusty winds of 35 to 60 mph kept wind chills in the single digits to negative teens throughout the day.
On December 23, 2004, a strong storm system lifted northeast out of eastern Texas and moved through the Ohio Valley. Snow tapered off by early afternoon with most locations receiving between 6 to 10 inches. Strong northerly winds to 30 mph, and up to 45 mph near Lake Huron, also caused blizzard conditions with significant blowing and drifting of snow. Here are some of the higher snowfall totals: Burton 7.5 inches (Genesee), Caseville 8.0 inches (Huron), Dryden 7.5 inches (Lapeer), Deerfield 9.0 inches (Lenawee), New Baltimore 9.0 inches (Macomb), Dundee 8.0 inches (Monroe), Bloomfield Hills 9.3 inches (Oakland), Saline 8.2 inches (Washtenaw), Romulus 8.8 inches (Wayne), and Port Huron 10.0 inches (St Clair).
Forecast Discussion
- Wintry mix of precipitation today into tonight A low pressure system centered over far southern MN early this morning will continue to move east and bring our area a wintry mix of pcpn today. Very light warm air advection snow showers/flurries will clip our far northern fcst area early this morning (prior to daybreak). Steadier pcpn will begin to develop during the mid to late morning hours and will continue through the afternoon and evening. Fcst soundings suggest pcpn will fall mainly in the form of snow north of the I-96 corridor with potential for two to five inches of accumulation (relatively highest amounts within that range occurring over our far ne fcst area up around Clare). A consensus blend of latest higher res model guidance and fcst soundings suggest that a wintry mix of pcpn will occur near to south of the I-96 corridor. This wintry mix will really cut down on any snowfall (less than an inch of snow is fcst near to south of I-96). The 00Z HREF FRAM suggests potential ice accretion would be very light and confined to areas near/south of I-96 and we are forecasting trace amounts to less than five hundredths of an inch of -fzra. This is still sufficient enough to result in some travel impacts. Pcpn will wind down near to south of I-96 this evening but we expect that deformation zone snow will linger over our northern fcst area through most of the evening. This deformation zone snowfall will taper off by around midnight as mid to upper level deformation zone dynamics shift east of our area. We decided to leave the winter wx adv start times (12Z this morning) unchanged for our central/southern fcst area as latest runs of the HRRR show potential for light freezing rain/freezing drizzle to develop fairly quickly from west to east between 12Z and 15Z. - Gradual moderating trend of temps late week through the weekend Overall trends in numerical guidance the past 24-48 hrs show a bit slower of a moderating trend of temps through midweek. It now appears that high temps will only reach the mid 30s on Christmas Day and Wednesday. Predominantly dry wx is expected on Christmas Day through midweek. Temps will only be around 1-3 degrees milder incrementally Thursday and Friday before stronger waa boosts high temps well into the 40s for the weekend. - Rain showers next weekend After potential for some warm air advection showers Friday we expect better potential for some showers for the weekend as deeper moisture will be in place by then. A low pressure system over the Arklatex region will move ne and likely bring steadier rain by Saturday night and Sunday.
Let it snow, let it snow, let SNOW!!!
I know one thing, January 20 is going to be a GREAT, GREAT weather day!!! Future is looking very bright!! BRING IT!!!
Sure is
It’s almost January and we are well above normal for Snowfall in GR! Great start to winter!
It’s almost January and Southern Michigan has yet to get a big synoptic snow event. That’s wild! The only snow has been lake effect due to our warm lakes after another warm year.
Breaking>>>>> it is time to review the FACTS!
1. Above normal snowfall for GR this month!
2. Above normal snowfall for the season!
3. We have already seen 1 winter storm warning and 3 WWA’s! Wow!
4. The CPC shows GR with above normal snowfall in January!
5. Winter is by far the best season in MI!
6. Cold and SNOW rocks!
7. Rock n roll will never die!
8. It is a good time to buy that new snowblower you have been thinking about! Get prepared!
Snow on the ground and another WWA in progress means another white Christmas! Incredible!
Rain and warm temps = another green Christmas!
Michael,
Please tell your wife Happy Birthday!!!!
It was asked yesterday what percentage of years in the past had white a Christmas. Percent of years with a white Christmas (1” or more on the ground) at Grand Rapids by decade since 1950. (1950’s 50%) (1960’s 90%) (1970’s 80%) (1980’s 50%.) (1990’s 70%) (2000/09 80%) (2010/19 50%) 2020/23 50%) At Lansing (1950’s 40%) (1960’s 80%) (1970’s 80%) (1980’s 60%) (1990’s 50%) (2000/09 80%) (2010/19 50%) (2020/23 25%) The most on the ground was in 1951 with 20” at Lansing and 22” at Grand Rapids.

Thanks for compiling the data, Slim.

For today the average H/L is 34/23 the record high of 60 was in 2015 the coldest high of 8 was in 1960. The record low of -11 was in 1989 warmest low of 45 was in 1979, 1941. The most snowfall of 7.5” was in 2022 the wettest was 1.02” in 1932 the most snow on the ground was 19” in 1951.
