this is busting hard for most of swmi.

SE Ottawa and NC/NE Allegan counties seem to be the only place where the radar is indicating anything close to steady snow. The snow seems to form across Ottawa county and head south/south east into Allegan and dissipate (at least on the GRR radar). I don't see any significant accumulations like they were advertising, but maybe something can get going this afternoon. I don't know.

Pretty much.. Typical LES. Flow remained too bent to far to the north ( nw ) for too long and moisture sucked. Thankfully i have managed to sneak in about 4" here so far since yesterday. Most of it though was yesterday. Basically a inch since yesterday evening? See what happens now as the main stuff is now dropping in. Thus the fat lady is not done yet.

It's one I made. The heavy snow bands stick out really nice.

WOW!!!

michsnowfreak is probably pissed right about now (he's on the edge of the band and will see a shorter duration), but MAN!!! That band was something else. All the roads are snowcovered and I have about another 1 or 2 of snow on the ground. That was easily the heaviest snow of the season. Everything's fully snow covered now.

IWX confident that impressive LES will occur from this episode. Aviation forecast thinks South Bend could receive very heavy snow. I include part of the late Friday afternoon AFD. Light snow now here at Elkhart. Good to have tomorrow off to watch this unfold.

IN THE WAKE

OF THE WAVE...THE MUCH ADVERTISED LAKE EFFECT EVENT WILL BEGIN TO

TAKE SHAPE WITH ONE OR MORE DOMINANT BANDS SETTING UP AND AFFECTING

PORTIONS OF THE AREA. ALL PARAMETERS MENTIONED THE PAST SEVERAL DAYS

REMAIN...AND WITH INCREASING CONFIDENCE IN WARNING CRITERIA

SOMEWHERE ACROSS BERRIEN...CASS...ST JOE INDIANA AND ELKHART COUNTY

LATER TONIGHT INTO SATURDAY NIGHT...HAVE UPGRADED TO A WARNING FOR

THESE AREAS. EVEN THOUGH SOME LAKE ENHANCEMENT WILL BE OCCURRING

THIS EVENING...DID KEEP HEADLINE STARTING AT 6Z AND WILL LET EVE

SHIFT MONITOR TRENDS. LOCALLY STUDIED TYPE 6 LAKE EFFECT SETUP

APPEARS ON TRACK DURING THE DAY SATURDAY INTO SATURDAY NIGHT. AS

MESO LOW DEVELOPS ACROSS NORTHERN LK MI AND DROPS SOUTH A SIG BAND

OF LAKE EFFECT SNOW WILL TAKE SHAPE AND MOVE WITH IT. THE BAND /OR

POSSIBLY BANDS/ WILL BE QUITE TRANSITORY MAKING EXACT AMOUNTS TOUGH

AT THIS POINT. IN THE WAKE OF THE MESO LOW...WHICH COULD PENETRATE

WELL INLAND...A MORE STEADY STATE BAND SHOULD MATERIALIZE. WHILE

TRENDS HAVE SUGGESTED THIS WILL MAINLY BE A NW TO SE

ORIENTATION...LOCAL WRF DATA AS WELL AS OTHER HIGH RES MODELS

INDICATE THERE COULD BE A PERIOD WHEN THE BAND COULD SETUP ACROSS

MUCH OF LAPORTE COUNTY POSSIBLY INTO STARKE COUNTY. AS THE BAND

MOVES BACK AND FORTH...ADVISORY TO WARNING CRITERIA SNOWFALL IS ALSO

POSSIBLE ACROSS PORTIONS OF MARSHALL COUNTY INTO NORTHERN KOSCIUSKO

COUNTY. FOR NOW HAVE OPTED TO KEEP WATCH GOING FOR NOW IN THESE AREA

WITH MOST FAVORABLE WINDOW POSSIBLY NOT TILL AFTER 12Z.

Im pissed, but only because I was at work and couldnt really enjoy it. The band actually hit us head on, and all I can say is WOW on how heavy it was shortly after 5pm, and at rush hour too. Wish I had my camera (was at work anyway). In that band alone, DTW picked up 1.0" of snow in the hour, and mby picked up 1.4". Snow depth is now a solid 2" at DTW with about 2.5" here. Everything is a winterwonderland with that heavy whiteout of snow causing of flocking of fluff on the trees. This is as good as it gets for les here!

Snowfall totals:

Jan 6th: 1.6" (0.08" wtr) imby, 1.4" DTW (0.07" wtr)

Jan 7th: 1.7" (0.06" wtr) imby, 1.2" DTW (0.04" wtr)***thru 7pm

DTW obs for today and yesterday, again, as good as it gets for les here.

Sweet.

Actually, I wasn't at home either. Basically running around in SE Macomb County (St. Clair Shores & Eastpointe) and Grosse Pointe. The most impressive part about it was the drastic transitions between the heavy snow squalls and the areas where it wasn't snowing. In SE Macomb County I was virtually on the edge of the band for most of the time as it rode along/north of the I-696 corridor (those areas look to be the big winners with local 3-4" amounts) so the snowfall intensity & visibilities were quite variable. Then heading over to Grosse Pointe it looked like a summertime thunderstorm with the shelf cloud hanging over (right before the squall completely took over). The air even had that calm winter storm feel to it before the big squalls came through which just made the event even better.

I am quite jealous of Novi/Wixom however. From what I could discern listening to WWJ-950, they got completely rocked!!!

It does look like the eastside may get some additional snow as the winds come off Lake Huron late tonight/tomorrow.

Ok, just took my 24 hour snowfall measurement, and we got 1.3" of new snow (0.05" liquid) and 5.0" total on the ground.

Supposed to take it every 6hrs.. :P Or did you? What is the final total?

I am not gonna lie either. I said to heck with it and did not bother.

For those wondering about measuring snowfall correctly..

http://www.crh.noaa.gov/grr/coop/howto/measuresnow/

If your daily schedule permits, you may wish to make a snowfall observation every 6-hours, beginning with your regularly scheduled time of observation. This is the procedure followed by NOAA's National Weather Service Forecast Offices. Follow the same rules for a once-a-day observation, but the snow accumulation reported will be the greatest for the previous six hours instead of 24 hours. If you take your observations at this frequency, make sure that you clear your snowboard (or other measuring surface) no more than once every 6 hours. Record the frequency of observations during the day in the comments section of your report. Never sum more than four, six-hourly observations to determine your 24 hour snowfall total. If you use more than four observations, it would falsely increase snowfall totals.

Sucks that it was a bust for you guys, well it seems like yesterday was a bit of a good bust and today a definite bad bust, but 5" on the ground is nothing to sneeze at. So I assume total 2-day storm is at LEAST 6", probably more?

Again, for lake effect in this area of SE MI, cant complain as it basically met/exceeded my expectations.

Jan 6th: 1.6" imby (1.4" DTW)

Jan 7th: 2.1" imby (1.7" DTW)

The fluffy snow of course settles, so after a 2-day total of 3.7", the depth is actually in the 2-3" range (generally 2.5"). It was a nice wintry night for taking pics, this type of snow just lights everything up.
