MRX issued a WWA for the Plateau, and OHX did for their Plateau counties as well. 1-2 inches for 1500+, 1 inch for under 1500.

Got two videos of the thundersnow… I can go to sleep in peace now. https://imgur.com/a/pubD2KK https://imgur.com/a/ZYInPQz

Earth Cam from Chicago just now, compared to what it normally looked like earlier in the evening.

Just leaving a busy evening shift. TAF verified (edit: at MDW, need ORD still) [emoji123] Sent from my SM-S936U using Tapatalk

Someone I know has reported graupel.

Some really high DBZ coming ashore now. Likely graupel/hail and more thunder to come

My cousin say this is the heaviest snow he’s seen since the 2011 blizzard. Edit and saw the thundersnow

Saw the lightning flash from my hotel room in Chicago river north

Right over downtown on the feed.

THUNDERSNOW!!!

Quarter or bigger flakes going on out there now, the ground is white. Solid dusting.

Quite hard to measure with the wind gusts, but I’m measuring around 2.5” in the past hour. With close to 3” total accumulation thus far in Wicker Park.

Visibility is effectively zero on that Skydeck webcam now.

You’re so right haha

DAB+ vibes now locally as trajectory and upscale radar trends are not promising. Still an awesome event to watch unfold.

31 and moderate snow currently. This isn't organized enough to get us much of anything, as the snow showers last 20 or so minutes then clear out. Hopefully the sub freezing highs and some instability work in our favor tomorrow afternoon.

A reset has been done if he could try to log in when he gets a chance.

Here’s the 500mb vortmax that is inducing the inverted trough. You can see the “kinks” in the isobars it’s causing (the actual trough) as the PVA induces pressure falls. It’s the same type of way we get our inverted troughs. But it’s perfectly situated so that it moves southward over Lake Michigan. The extra instability from the warm lake waters is making this locally heavier than it would’ve been otherwise. And yeah, then the low level flow aligns along the long length of the lake and we get the LES streamer behind it for a short time.

So yeah…that’s your inverted trough moving through right now. The LES band is setting up in its wake and will move eastward with time.

Tropical downpours coming down good right now. Now I know why there’s been so many frogs hopping around this evening!

Can't fathom what is happening, been burned too many times with LES.

Just out from LOT (11:37 PM): THE INITIAL PUSH OF SNOW THAT DROPPED VIS DOWN TO 3/4SM AT CHICAGO TERMINALS IS PUSHING SOUTHWESTWARD TOWARD KPIA. HOWEVER, THE NEXT BAND OF SNOW IS RIGHT ALONG THE LAKE SHORELINE AT THE TIME THIS DISCUSSION WAS PUBLISHED. CURRENTLY CONDITIONS AT CHICAGO TERMINALS ARE VFR, BUT WITH THE NEXT BAND ABOUT TO MOVE ONSHORE, THE TAFS WERE SENT WITH WORSE CONDITIONS DUE TO THE EXPECTATIONS THAT THINGS WILL DETERIORATE QUICKLY AFTER 06Z. THIS BAND WILL BE HAVE MORE VIGOROUS SNOW RATES AND STRONG GUSTY WINDS. LOW VIS IS EXPECTED, BUT MAY EXCEED EXPECTATIONS AND BECOME SUB-1/4SM. ADDITIONALLY, BUOYS HAVE ALREADY REPORTED GUSTS TO 31 KNOTS, AND WHILE 35 KNOTS IS IN THE TAF, IT IS ENTIRELY POSSIBLE THAT GUSTS TOUCH 40 KNOTS AT TIMES. IT IS POSSIBLE THE THE TEMPO FROM 06Z TO 09Z IS A HAIR LONG, BUT HAVE MODERATE CONFIDENCE THAT THERE COULD BE 3 HOURS OF REALLY INTENSE SNOW RATES. LOOKING AT REGIONAL RADAR, THERE IS A LONG LAKE ORIENTED BAND OFF THE WISCONSIN SHORELINE MOVING SOUTHWARD. THIS BAND WILL BE "ROUND 2" AS IT MOVES INTO ILLINOIS. THERE WILL THE EXPECTATION IS THAT THERE WILL PROBABLY SOME TIME OF "BREAK" IN THE INTENSE SNOW BEFORE IT MOVES SOUTHWARD (LONGER AT KMDW AND KGYY). CAN'T RULE OUT SOME QUICK VFR CONDITIONS, BUT FELT MORE PRUDENT TO LEAVE IFR/MVFR CONDITIONS FOR ONGOING SNOWFALL. NEVERTHELESS, A SECOND ROUND OF INTENSE LAKE EFFECT SNOW IS EXPECTED BEFORE DAYBREAK.

Absolutely ripping here. This feels like thundersnow any mintue now… https://imgur.com/a/6GqbyUD
