McHenrySnow

Up to 37º. Odd.

34.7º here this morning. I'm thinking 2" max here at this point. I can definitely see some areas overachieving and others underachieving. Anxious to see just how robust some of these bands can get this afternoon.

At the end of the day, I agree more with an impact-based system, just not sure those counties will experience anything drastically different from the rest of N IL. The general public doesn't know and doesn't care about "criteria" anyhow.

Quite interesting. Definitely wouldn't have thought they'd do that. Haven't really seen anything that would meet the requirements.

Andrew Pritchard tweeted this, he's based in Champaign.

My call for McHenry as well, though may be a bit high.

I think that's a good call for your area. I'm assuming LOT's watch will also end up an advisory and the rest of N IL north of 1-80 gets one as well.

I can assure you there is no urban heat island significantly affecting temps in McHenry or Lake Zurich. The snow on the ground is keeping us this cool, if the ground were bare, we would likely be into the 40s. Different story in the heart of the city, certainly. And that will likely be a big player into the accums in the city with such marginal temps as is.

That's what happens when you play with pigs. You both get dirty, but they like it.

It's fine, I know you're just being an asshole.

I have a weather station, of course.

Didn't say otherwise. Yeah, tomorrow we'll have clouds, but also actual warm air advection.

I don't live in the immediate metro and I'm sitting at 36º.

I understand that. I also understand that we're blowing past forecast highs at noon.

If temps today are any indication, I'm going to be more concerned than I was about temps.

I keep thinking back to January 2019, the week of the extreme cold from the displaced polar vortex and remember a system that had what would normally be a garbage track for Chicago surprise us with an all snow front end thump. I believe we got 3 or 4" in the city. It warmed up above freezing and we had drizzle the rest of the day and then the arctic front eventually made it through the area the next day or so? Anyhow, this reminds me of that somewhat. Not necessary the atmospheric setup, but the heavy wet snow preceding the arctic blast.

Yeah, the nice thing is snow will stick to snow, so even if we wouldn't see much on paved surfaces, it might be enough to counteract melting and/or increase total depth.

3k NAM actually increased totals across LOT.

No major changes on the 18z NAM it appears.

Hate to say it, but I do think the Ukie makes more sense right now. I have all of the same concerns Hoosier pointed out.

Oh, I mean in the Chicago metro area only.

Might the NW burbs win this round? @Cary67 and I would appreciate it.

Low party at @A-L-E-K's house Thursday night per 12z GFS.

A very good hit for the vast majority of LOT.

Yeah, QPF shows a bigger difference than low placement.
