Chicago Storm

We were in one a little over a week ago.

The peak coldest temp and wind chill this week at ORD was on Monday night/Tuesday morning. The low temp was -5 and the peak wind chill was -22.

i believe that we only have ever had a handful of members from that area. sort of surprising, given it’s a bigger metro/urban area.

you do you, guy.

yep. i get that there 'needs' to be a cop-out or fail-point. however, it isn't convective issues, it very clearly was a trend towards an even more janky H5 evolution...which carries elsewhere.

convection most definitely did not block moisture transport, as that heavy convection was modeled for days, even on guidance showing a heavier hit for MI. again, the difference came aloft, with an even jankier H5 look...which is also why the surface low kept trending east. let's take a look at the NAM, which was one of the last to let go of a snowier solution... pretty clear cut look on why things trended southeast and weaker. obviously if you trend H5 jankier, the associated surface low in turn ends up weaker/southeast, and moisture transport/850 low shunted east. also, note on the second image of the heavy convection modeled days ago.

but, it’s actually not the reason. look at the H5 changes over the past few days and you have your answer.

and you say i’m the asshole…

WAA burst of snow this evening was as advertised. Peaked with a period of SN at ORD, with a final snowfall total of 1.8”. The seasonal snowfall total is now 14.8”.

They have been issued int he past for the same. Classic inconsistencies in the NWS.

The internally don't follow their usual routine is part of the issue. Any other time, a WWA would have been issued.

Easily.

That WAA wing of snow is going to be a brief, but nice period of 'pound town'.

Oh, I'm aware. I just don't expect something out of my climo that isn't possible.

We're all dog hunters at heart. Josh and the deep winter-ites are good with the nickel and dimers, but for most here, they want quality events. Personally, I'd prefer summer year-round, but do have a soft spot for chasing dogs in the winter.
