With Dec in, we have concluded 2022 with a near avg anomaly. 5/10 yr trends respectively.

Prelim data in for Dec, and with 1901-2000 baseline, ended on the milder side. 1991-2020 baseline would be closer to average with the split between our western, and eastern areas as seen in MRCC map below. Also have the 5/10 yr trend charts. Some here wanted to see both. 9 out the last 12 Dec's have been on the milder side.

Lake effect starting to form on the north shore as 850's turning a little more E/NE. Colder air funneling in from the northeast. Will see how it goes tonight.

weatherbo under a band of heavy synoptic snows. Wetter stuff. Tomorrow should be a little colder with conversion over to more lake effect. Enjoy!!

Winds at the surface, and aloft will be out of the NE, and with temps dropping in CA below zero, that should help enhance, and even convert to straight LES starting tomorrow into Friday am.

Radar returns showing a slow westward movement at the moment. Not going anywhere anytime soon.

Duluth is at the northern most edge of precip right now with the band across E C MN into N WI. 3-6" being reported early this morning, but reports later should show a lot more under that band. Storm warning in effect for them.

4" this morning. Winds off the lake up to 30+ mph blowing it around some. Just some light snow showers off and on coming off the lake. Hope to see a more organized band develop later in the day, but that could end up going down towards Duluth.

Just looking at temps on Wed into Thurs am (turning quite negative) with surface winds, and 850 winds running E/NE to NE, I'd say a LES event is possible along the head of the lake. Twin Ports (Duluth/Superior) may do well. Maybe even myself. But then as winds start to calm, and turn more to the south as another CA front goes by north of me, that should send it up my way more, and the north shore in general for Thurs night possibly. It would be short tho as 850's become more SW to W, and surface winds respond in kind. Just an interesting look at a possibility.

This next system will only bring 1-3" of snow for me this time around. NE winds might allow some light LES in the mix, so we'll see how the lake responds.

Duluth broke its Dec snowfall record just barely. Here's the top 10 list. 6 of the 10 are in the last 20 years. 2015/19/21 are in the 14/12/13 positions respectively. Very snowy Dec's. 2022 44.9" 1950 44.3" 1996 42.2" 2013 39.9" 1969 38.8" 1968 37.7" 2008 37.1" 2007 35.4" 2005 34.5" 2009 33.4"

Wrote this back in Nov. Still holding to it. Back and for between milder, and colder conditions.

Partly right for this forecast. CA front moves across the northern areas, but the energy I saw holds back a day, and becomes a separate system starting Mon the 2nd, bring rn/frz rn/snow. Close call. Well that ends 2022. Will be using the Holiday 2023 thread next.

Biggest total from the U.P. MI is near Baraga with 42.8" with lots of 2-3' readings across N MI in general.

MERRY CHRISTMAS EVERYONE!!

Winds started howling after sunset yesterday. 50+ gusts. It was wild there for a while, until just after midnight. Winds settled down some, and are now back up to the 40+ range today. Duluth really close to a monthly record for snow in Dec. One week left. I think we'll get it NP with the upcoming pattern. Probably smash it. 1950 44.3 2022 43.1* 1996 42.2 2013 39.9 1969 38.8

Areas of N MI reporting 2-3' of snow this morning, and it's still snowing up there.

Now that's what I call a BLIZZARD!

Winds had relaxed at the surface here in town this afternoon, but this evening they've amped up quite a bit. Very similar to early this morning. Gusts 35-45 mph. This afternoon they had only been 25-30 mph.

3-11" of snow being reported early this morning across the northern areas of MI from the synoptic/lake enhanced stuff so far. Snow should amp up a bit as the cold N/NW flow kicks in hard for the weekend.

Two Harbors cold records for low max, and min. Low max Dec 21st (4th) 1989 -6 1924 -4 1921 3 2022 5 Dec 22nd (3rd) 1960 -1 1989 4 2022 5 Dec 23rd (tied 1st) 1914/2004/22 1 Min Dec 21st (7th) 2022 -13 Dec 22nd (4th) 1914/24 -18 1916/89 -17 1998 -15 2022 -14 Dec 23rd (tied 6th) 2004/22 -11

Near record Low Max temps from Duluth. And top 10 record Min temps Dec 21st (3rd) 1989 -9 1924 -8 2022 -4 Dec 22nd (tied 2nd) 1983 -5 1943/90/2004/22 -4 Max temp today (23rd) should be top 10. Update: Tied for 8th at 2 1878/92/97/1984/2013/22 Dec 21st (tied 6th) 1989 -28 1916/70 -23 1921 -22 1973 -20 1924 -19 1976/2022 -18 Dec 20th was tied at 9th 1921/2022 -14, and Dec 22nd was tied at 8th 1969/2022 -12. This morning's low was -14 which places that at 8th 1878/92/1953/2022. Very cold for this time of year.

Temp around 0 right now, with windy conditions. Not too bad, tho. Earlier this morning, winds were very gusty, whipping up the fresh snow we just had, but now pretty mellow in that regard. Upper level clouds moving in from the E/NE. Radar picking up some returns along the North Shore as the moisture interacts with the ridges along the shore. They are moving SW along the shoreline. Extremely light snow bands, but that will contribute to limited visibility along Hwy 61 north of me.

Snow streaks across the N Plains. Pretty cool, and dangerous.

Lower Lakes getting hammered once again for Christmas weekend. Buffaloweather should be in here soon, as well.
