My 4" of snow melts down into 0.63" liquid, so the ratio is very low.

Unfortunately we’ve had 3 fatalities in front of my house🤣🤣

Solid 1" here with a fairly heavy, wet snow falling at 30 degrees and enough of a north wind to blow it around a little.  Streets are awfully slick.  My grids say 1-3" today and 1" tonight with no WWA

Awesomeness!!!

GRR update

Quote

.UPDATE...
Issued at 1130 AM EST Sat Dec 12 2020

The sfc low is now centered near AZO and will deepen this
afternoon as it tracks across the Thumb then into srn Lake Huron.
Rain/snow line has nudged a bit farther north and extends from
just north of MKG to near/just north of Mt Pleasant.

Snowfall reports so far have been in the 2-6" range, with the
highest amounts from Le Roy to Harrison. Power outage map shows
numerous outages in the Harrison area already from the heavy wet
snow, and central dispatch there confirms trees and power lines
down from the weight of the snow.

Best mid level deformation will be setting up soon across the
warning area, with strong FGEN forcing/omega within the prime -12C
to -18C dendritic grown zone region. Snowfall rates could reach
inch per hour for a few hours before the intensity diminishes
after 4 PM. Deformation axis extends all the back into Iowa so
even after the heavier snow ends light snow will likely continue
into the evening hours.

Sfc temps have been somewhat marginal (slightly abv freezing) and
will continue to be through the rest of this event, holding down
snow depth measurements from melting/settling. As such, the
highest final accumulations (up to 10") will be limited to areas
where topography is greater than 1000 ft and where sfc temps are
colder, which includes areas near/north of Big Rapids/Reed City,
Evart, and Harrison. Travel will be particularly dangerous today
along the U.S. 10 corridor east of Baldwin, as well as along the
U.S. 131 corridor north of Big Rapids.

The lower end snow amounts in the warning area are expected to be
west of a line from Baldwin to White Cloud, including Pentwater
and Ludington, as well as south of Big Rapids. These areas will
probably end up being under 6" for final amounts.

Meanwhile rainfall amounts south of the rain/snow line have been
generally 1 to 1.5 inches so far. Could see another half inch or
so of rain early this afternoon before mid level dry slot south of
the deformation zone sweeps in this afternoon. Thunder looking
unlikely at this point.

@Slowpoke Seems you're in the cross-hairs for best outcome. As you said, great way to start winter with a heavy snow base. Hopefully it's here to stay and works out as such. Enjoy that ride

Just got done taking more snowfall measurements and it hasn’t shrunk or melted much so far. I’m going with 4” as many solid surfaces have that much. It’s over 4” on the grass which I never trust just sticking a ruler down through. I could dig it away and see how thick it was on top of the grass as wet snow mostly sits on top without sifting down into the grass. I’m still in the process of melting 2 core samples just to see approximately how much liquid came from snow. One core is from a solid board surface and the other from the grass. It might be the first time I took a sample on the lawn, but it worked well with wet snow! It packed right in with hardly any left on the grass. Was surprised, but storm total liquid was a whopping 1.70”. 
 

Now I need to catch up on this these wx threads since I’m a few days behind.

Yep the GFS was awful for this storm. It did a good job sniffing out storm potential up to 10+ days out. So kudos there but in terms of any reliable details of the storm it was atrocious. Like I said repeatedly the GFS has major thermal issues. I noticed it this summer and it continues now in winter. So a marginal temperature event like this it’s no surprise it couldn’t handle it. The 00z run shows 1-3” across the state at best. Dubuque is already well past that. 

Wasn’t awful.  Just missed the defo band.  Track was good.  Nailed Michigan part of the storm perfectly.

3.5” here as well as KLNK. Really beautiful snow and not bad considering the crappy pattern. Some melting so far, but still around 2.5-3” left, hopefully it’s not nuked too soon. Congrats to everyone who’ve cashed in.

My 4”+ from the lawn also melted to 0.63” and 4” from a board only 0.53”. Shouldn’t vary that much, but anyway....

Ended up with 8” or so here at Higgins Lake. Lost pwr for a bit a couple times but we were/are really lucky because it came back on and there are trees down everywhere around here. Made for a really nice evening snowmobile ride. This heavy snow should make a great start to the winter play activities up here like cross country and down hill skiing, snowmobiling, stuff like that.

Consolation flakes made my night. Even dusting up the grass and cars near BC. Great for my first night lighting up the holiday decorations outside. Rolled into town and it was so much more festive with the flakes flying. Jingle bells..jingle bells..

There looks to be around 4 to 7" of snow on the ground in northern lower Michigan. The reported snow fall at Alpena was 13.7" and at Houghton Lake 7". I had a total of 1.83" of rain. The rain did end as a period of snow here at my house and I had enough to cover the roofs of the houses and on cars. This AM there is still a little on the SUV that I park outside. It is cloudy and 31 here at this time.

The GFS thermals were terrible for Iowa at least....

 

Euro Op was just as bad in the other direction showing parts of NMI getting 20+ inches. Double what actually happened so it's thermal profile is most likely too favorable in these marginal conditions. Imagine that was the only model you had to look at. You'd think "2 footer incoming" and be very disappointed by 10" totals. Or maybe happy if your power was still on. Idk

Thank you buddy. It's pretty great to see the flakes again. Just wrapped it up a few minutes ago actually. Couldn't be more happy. I'm silly when it snows. I love it.
