Model agreement on a pattern change 1st weekend of January. Below normal, but nothing memorable. Regardless, I’ll take it.

Some weather history for southern lower Michigan for December 22. 1957: Balmy weather prevails with highs in the mid-50s. Muskegon sets a record high of 55 degrees. 2000: A long siege of arctic air and lake effect snow continues across Lower Michigan. The high temperature at Lansing is only 9 degrees with lake-effect snow showers swirling. It will be the coldest December of the 20th century at Lansing. 2013, an ice storm impacted locations from the northern Detroit suburbs to the Saginaw area as significant moisture became entrained along a frontal boundary. Widespread ice accretions of 0.5 to 0.75 inches were reported and numerous trees and power lines were downed. The ice storm even prompted Shiawassee County to declare a state of emergency due to unsafe traveling conditions. Further south, the precipitation fell as heavy rain while Bay, Midland, and Huron counties saw 2 to 4 inches of snow. 1872, the temperature dropped to -24 degrees overnight in Detroit. This temperature reading is unofficially the lowest temperature ever recorded in the city of Detroit.

Night Shift 6z GEFS. Moses Lake 850s. Coldest run yet I believe. The mean temp is down to almost -7c with a large cluster of cold members. There are still some warm members which are skewing the mean from going even colder, but overall this is decent progress in the right direction signaling a pattern change beginning around roughly New Year's Eve.

The official H/L yesterday at GRR was 25/9 there was a trace of snowfall the sun was out 65% of the time. There was 3” of snow on the ground. For today the average H/L is 34/23 the record high of 57 was in 1941 the coldest high of 15 was in 1989,1951 the record low of -11 was in 1989 the warmest low of 44 was in 1931. The most snowfall of 8.5” was in 1951 the most on the ground was 19” in 1951.

PHX did it again...4 days of Record highs in the Valley of the Sun! It was a balmy, 79F, with calm winds nearly all day along with blue skies. The next 3 days we shall have temps remain in the upper 70's until Christmas Day when a storm rolls through the 4 corners. It'll be a nice and Festive Snowy Christmas Eve and Christmas Day for those traveling up to Park City, UT...or...Aspen/Vail area...One of my Bucket List trips is to experience a Holiday Season up in the mountains and hopefully Mother Nature delivers bountiful snow.
