Chicago Storm

18z Euro…

Overnight will be 48 hours out from the start in the CWA, so they're going to have to go with a watch with the evening or early morning package.

Looking over guidance from today, the big thing that sticks out is how much wetter the Euro/EPS are compared to almost all other guidance. We have seen through the years that the Euro tends to be on the drier side more often than not, and when it is, it is usually close to reality. So, it'll be interesting to see how it does with being on the wetter side this go-around.

CJ is the worst of the worst.

LOT is 100% going to play it safe this go-around, after the single person blunder with the LES event.

500mb evolution on the 12z Euro is…

The NAM is tentatively scheduled to be retired in March 2026. After a ton of delays through the years for various reasons, we finally have a time. I'd expect it may shift a bit, but the point is, the end is finally near.

As is always the case in good patterns, there two routes that are always of a concern… Too suppressed or well phased. This one is currently trending towards the latter recently.

NOW it won’t happen.

stop looking at the op gfs.

As we know, there’s a multitude of ways it can fail (our recent history says it will), but you have to admire the look at least.

Short and sweet for now… 2013. This is the best looking pattern on paper I can recall when heading into December since then.

This was from just a short time ago near home…

I can see the lights even here at ORD currently.

Highest report I've been able to come across is 17" in Winthrop Harbor.
