Jan 17th-19th Rain/Snow/Mix/LES System

As expected and usually is the case with winter precipitation my liquid total is a lot higher than ANY other report I saw. The reason is I lean my gauges into the wind at maybe 30-40° and that makes a huge difference in how much falls into the gauges! Around a year ago I did my own research to make sure and I was really surprised at the huge difference! I had 2 pairs of identical gauges and one of each pair I leaned toward the wind and the other 2 not much and the result was almost another times as much (nearly 100% more) liquid equivalent (from snow) in the leaning gauges!! Which actually makes sense when you see the snow falling almost horizontally. Just thought I'ld share that info so you know why my totals are higher. Yesterday's results from 4 gauges was around 1.30" liquid! 2 gauges had 1.30", one had 1.34" and one 1.08".

 

Edit: Electronic rain gauges won't work to lean! Lol Plus they don't register frozen precip anyway.

Also you can try and do your own research if you have two identical gauges and create more work. Ha

My gauge catch melted down to 0.73" liquid... pretty close to what most models were spitting out.

Snow has finally tapered off.  Attm, cloudy and starting to feel that bite in the air w temps at 34F. Neva went to any mixture. Remained all snow. :D Just finished cleaning out my property w my snowblower and man, I must say, its a beautiful scenery out there w a ton of snow. My sub is a mess though, not sure when the trucks will swing on by.

Whoa! Just came up from the basement and theres a snow shower goin on with the strong wind. Blizzard like conditions!

I hope some of those convective snow squalls start popping up later this afternoon enough to lay down a fresh coating over the slushy (soon to be) frozen glacier.

It's pretty awesome. It's literally snowing sideways with the wind. It stops for a few mins and then kicks back in. Nothing is showing up on radar though. Down to 9°. Full blown winter out there right now!

I cleared the driveway earlier before the snow got wet and used the snowblower. At that time I had 5.8" of snow on the driveway. The plow came thru (I was surprised as in the past it generally took 2 to 3 days before the plow came thru) anyway the snow at the end of the drive was very wet and heavy. At this time it is getting windy and 34.

Thx...i know, it seems like this season it wants to give me either double digits or no snow :lol:

 

I didn't get as much as I did w my Vet's Day snowstorm, but, not complaining at all. Now the arctic air arrives. Winds are already starting to pick up. :ph34r:

I remember a day like that last January when the Polar Vortex swung through the region.  The radar was lit up with linear streamers and when you got underneath one of these bands it was a whiteout.  Awesome sight to see.

Just got under one when I was driving from Hiawatha to downtown. Wasn’t anything like James was describing. But it was still something. Vis came down to 3/4mi or so and it got gusty.

@ Beltrami, how did you score up there? I’m seeing some heft totals up in N MN. Did you get double digits?

I got about 7" by noon today. Sun was almost out til about 2pm when the wrap around snow started. Still snow showers out and might eak out another inch. The higher totals were in the arrowhead as usual.

Conversion band overhead. Hardest I’ve seen it snow in a long time. miss the lake effect this year.

 

Congrats!  Looks like the 96 corridor's getting this one. Just some pixie dusting here so far as has been the case with almost every LES event this and last year due to SLP's running N of here making the winds more WSW instead of WNW or NW. Per some SR models, it should shift my way towards the latter stages of the event but by then it will be transient and short duration of good stuff. Just not a favorable pair of winters down here.

So after more than 2 months with only one single light-weight snow to shovel, I got to shovel about 4+ inches of 5:1 concrete. And ofc, in this winter where warmth rules the roost, it was above freezing and blowing a "sea spray" in my face the whole time. Needless to say, my out of shape shoveling muscles are not happy campers right now. 

 

As posted above, after a 12 hr intermission during which every p-type known to man fell/flew, snow is again whitening the ground with temps already down to 25F (and falling). We tagged a balmy 38F for an hour or so mid-afternoon and there was a ton of slush/melting/run-off in streets and lots everywhere. Other than the lack of sunshine popping out, it had the feel of an early spring snowstorm more than a mid-winter event. 

 

I think I mentioned how the low-ratio stuff makes for awesome plow pile material. Snow Loaders were able to do just that this morning at the larger lots. This is from Kzoo, but we even had some 10 footers at the grocery store lot here in Marshall. The last of the old piles were all but gone.

I'm thinking that yby scored a small "jack zone" of sorts due to the (rare) strong SE winds causing some lake enhancement via Lake St. Clair and possibly even a 2 lake connection w/Lk. Erie as well. That fetch would be a bullseye for City of Macomb. You sure have the golden snow magnet this winter amigo. Hope your blower was up to the task.  ;)  :D

Action Recommended: Avoid the subject event as per the instructions Issued by: Detroit - MI, US, National Weather Service,

...

FALLING TEMPERATURES AND INTERMITTENT LAKE EFFECT SNOW SHOWERS WILL LEAD TO LOCALIZED ACCUMULATIONS AND SLICK CONDITIONS OVERNIGHT... WEATHER... * Lake effect snow showers will track across the area overnight. The potential exists for bursts of heavier snow showers to develop. * Temperatures will rapidly drop into the 20s overnight. * West winds around 20 to 25 mph with gusts to 40 mph. IMPACTS... * A quick of accumulation of snowfall on area roadways will be possible within any heavier bursts of snow. * The rapid drop of temperatures below freezing will cause residual moisture to freeze on untreated surfaces. * Reductions of visibility to less than one mile are also possible. && PRECAUTIONARY/PREPAREDNESS ACTIONS... * The combination of falling temperatures and lake effect snow will lead to slick driving conditions overnight, especially on untreated roads. Motorists are urged to use caution and account for variable driving conditions by slowing down and allowing extra time. * Prepare, plan and stay informed.

Could parts of Cook county get hit by some LES as a potential meso-low may form late tonight into tomorrow?  These type of set ups always are interesting to monitor as these dying lake bands have a mind of their own and can sometimes deliver surprise bursts of heavy snow.  I think @IndianaJohn is in a good spot.  

 

 

LOT's take...

 

 

 

Winds, particularly just above the boundary
layer, are progged to veer more northerly with time late this
afternoon and tonight, which is expected to allow lake effect snow
showers to edge back into our northwest Indiana counties and even
far eastern and southeastern Cook county. The dry nature of the
arctic air, and relatively shallow inversion heights (maxing out
around 6 kft tonight) should preclude significant measurable snow,
though amounts of perhaps 1-3" will be possible, especially
across Porter County where the longest residence time and
strongest convergence appears likely. Minor accumulations of less
than an inch may occur into the Cook county shore areas,
especially from downtown Chicago southeastward.

^^^ Nice. NWIN needs some love. They've not had it good at all. 

 

Meanwhile, like I mentioned yesterday, there's a chance for a "squall line" of sorts to move thru today as a last hurrah! of this event. I'll take it if it wants to show up. Just can't blink or I may miss it, lol.

 

-- Burst of snow by lakeshore today and along I-94 this afternoon --


Continuing the previous discussion, we are increasingly concerned
about a snow burst pushing south mainly along the lakeshore.
Although short in duration, this could be highly disruptive and
there are indications its effects could be felt much farther inland
near the I-94 corridor around 2 pm this afternoon.
Given that this
could be particularly impactful to travel, have extended the winter
weather advisory for our southeastern forecast area to cover this
scenario.

Forecast reasoning: This burst of snow will be associated with a
fast moving cold front dropping south during the day. Impressive
surface based convective instability is shown with this feature, and
this is being duly noted by snow squall parameter. This parameter
will be a good diagnostic to monitor on the SPC mesoanalysis page
today. Regarding significant inland penetration of the convective
instability, the NAM is aggressive as usual, but even the coarser
and more conservative GFS depicts this as well. Several convection
allowing models show a corresponding quick drop in visibility
associated with this narrow band extending all the way to Jackson.

Same here. Sun is out now. 11.3” total here (GRR officially 10.3) . Solid 36 hour event.

Awesome congrats. This was a great storm. Hopefully I can get some LES later today to increase my totals to near a foot! :)
