Looks like 7.6” reported at MSP as of 7 am

That jives with what I’m measuring 1-2mi north of the airport.

Once again, a tricky forecast to try nailing for LOT when models continue to shift areas of warning criteria snow in the NW areas.

Although, selfishly, the most recent Euro would be insane for my area.

Edit: actually maybe 7.3 officially, the 7.6 was at NWS office? Academic though.

Hard to be disappointed about the relative “underperformance” with those numbers across the metro at our latitude. Especially knowing it was always gonna be a +/- 50 miles situation with the heaviest band.

Will certainly be a fun 24 hours. See how long it'll take gusts to start, hoping for  some good GV storms maybe in a few hours, and I'd love to reel in some surprise death band tomorrow morning with winds but not holding onto that one ofc. Would love to see it happen though

12z HRRR hot off the presses

La Crosse AFD update talking about heavy thunder sleet this morning. Miss me with that!

Got to hand it to the GFS. Nailed the placement of the jackpot zone many days ago. Today is going to be a lot of fun.

Not a flake here in town yet. They still think L superior will produce along the shore tho with 3+". Looks like 1-2" across N WI into EC MN so far.

Here's the CoCoRahs site to get a better look at totals. They don't always get uploaded to the snow map right away. Just click the map (will open in a new tab), and make your parameter adjustments with the map options. https://www.cocorahs.org/

 

EDIT: Soon as I post this, --SN started.

Nudged just above 32 here as a line of thunderstorms is about to move through.  Will be curious to see what kind of precip they have

[Malacka11]

Is the nam actually doing something legit or is that just noise? I understand that we've been trending minorly better for NE IL again but

[Chicago916]

Morning storms looking fairly robust too. Saw some peeks of sun outside too

I will settle for this

Officially thundersleet.  Some of the best 32.4 degree thunderstorms I’ve seen in my life

Seems to me LOT has played this pretty good thus far.

Agree how many times have we been forecasted to get 1-3 from a deformation band and end up with 30 minutes of flurries

The infamous severe thunderstorm warning box within a blizzard warning.

chicago updated

 

We have opted to upgrade the Winter Storm Watch across our
northwest to a Winter Storm Warning from 7 pm this evening
through 1 pm Monday. We strongly considered a Blizzard Warning,
but have opted to hold off on that at this time, though cannot
rule out the need to upgrade as the event unfolds this evening.
Either way the combination of falling and accumulating snow
with widespread blowing snow and gusty northwest winds (up to
50 mph) will make for near blizzard conditions at times tonight
into Monday morning across northwestern IL. Total snowfall
amounts in the warned area are expected to be in the 3 to 6 inch
range.

In addition to the warning, we have also opted to issue a Winter
Weather Advisory from 10 pm tonight through 1 pm Monday for
areas east-southeast of the Winter Storm Warning. This
basically includes areas nearly as far southeast as the I-55
corridor. Snowfall amounts in this region are expected to be
lighter, generally in the 1 to 3 inch range. However, the
combination of the snow and blowing snow will also make for
hazardous conditions outside of the Warning area Monday morning.

[Chicago916]

MET from Central IL posted this. Would think this would extend north and east too?

Somebody already has 21" and there's a severe thunderstorm warning next to some 30 degree temperatures

[cyclone77]

Temp here has shot up to 54 degrees courtesy of humid southeast winds.  You wouldn't know blizzard conditions were in the offing in less than 12 hours.

Alright, who decided to do a funny?

 

[yoda]

Made it on here for now too lol

Temp holding steady at 32F here. A light glaze on above ground surfaces and had some pea size hail earlier. Watching reports out to the west, waiting for switchover later this afternoon.

i wouldn’t get comfortable with anything just yet (good or bad).

it’s a very complex evolution overall.

yep.

So mysterious 

[mnchaserguy]

Measured 6”. What a complete joke after what the models showed for so long. I swear the north metro has a weather curse.

[Chicago916]

Idk about using global models at short range, but interesting dual maxima of snow on GEFS in NW IL and NE IL. Who knows what happens.

Not really. He’s basically saying still a lot of moving parts and not to trust anyone solution. Which is playing out in real time. Note the model shifts just in the last 12 hours. Which is why I complemented LOT. Issued a conservative call but with some flexibility if short term trends change. Looks like 2-4 still in play here in Dupage. I’ll take it and than gladly close the book.
