Merry Christmas to all on this board! It's a cooler morning today as a pretty decent trough tracks through the 4 corners. Finally, a cooler day is ahead today with highs near normal and that is in the mid 60's. Looking forward to tracking some winter storms as we flip the calendar later next week!

Some Christmas Day weather history in southern lower Michigan. 1982: Southerly winds push temperatures into the 60s during the warmest Christmas on record for Lower Michigan. The unusual warmth is punctuated by scattered thunderstorms. 1983: Only one year after the warmest Christmas on record, southwest Lower Michigan is setting record lows with temperatures plunging below zero as a long siege of arctic air dominates the last half of the month. 2000: Lansing falls to 17 degrees below zero for their coldest Christmas on record. 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. 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!

Merry Christmas!!! Yesterday the official H/L at GRR was 36/30 there was no rain or snowfall. The sun was out 38% of the possible time. For today the average H/L is 34/23 the record high of 65 was in 1982 the coldest high of 10 was in 1983. The record low of -3 was also in 1983. The warmest low of 47 was in 2023. The most snowfall of 7.0” was in 2017, 1990. The most on the ground was 22” in 1951. Last year it was a warm 54/47. The overnight low here in MBY was 30 at the current time it is cloudy and 32. There is what I will call a trace of snow on the ground with many bare spots. So at least in MBY officially not a white Christmas.

I’ll swap you my light yellow that I am barely in for your pretty dark red!
