Have a pretty optimistic view that this will be the catalyst for a reanalysis of tornadoes from recent years for revisions to their ratings.

I'm in an "I'll believe it when I see it" mindset in regards to that.

Hopefully it occurs at some point, though... As we all know there is a good handful of tors that have most definitely been EF-5 through the years.

Different strokes I suppose. I enjoy summer as much as snow in the winter. I am not a hunter. Not sure how anyone finds sitting on your ass watchin your life pass you by hoping you can shoot an animal appealing. I prob would enjoy being away from people and enjoying the nature aspect of hunting. But I'd imagine most would rather fast forward through the rest of october/november.

i think you underestimate how many normies enjoy fall weather.

you're looking at it from the perspective of jonesing for interesting weather, where-as regulars do not care about that.

Some locations were able to sneak in a couple of early October 90°'s this past weekend.

MDW was one of those locations, with a high of 90° on Friday.

Some locations were able to sneak in a rare late September 90°+ day on Monday.

MDW was one of those locations, with a high of 90° on Monday.

I said this a week ago, so we'll see if it sticks this time... We are likely done for the year with 90°+ days, so the below will likely be the final overall tally for the year.

Probably the most significant pattern change we've seen in a while is on the horizon...

We're going to replace the constant re-loading +EPO with a re-loading -EPO and -PNA. This will likely will lead to a more active weather pattern than we've seen (That's not hard to do) and more of an up/down temperature regime, with some shots of real fall conditions.

not seeing any end to the mild weather anytime soon

ENS keep a re-loading a +EPO for the rest of the month.

If nothing else were to factor in, that would keep the mild/warm temps in place.

Nelson can't be a chill person here if he wanted to rustle frostfern's jimmies.

You are annoying.  Just scroll the fuck past if you don’t want to read asshole.  I don’t read half the shit posted here.  Why don’t you post something?

We added a couple more 90°+ days this past weekend...

It hit 91° at ORD and 92° at MDW on Friday. It topped out at 95° at ORD and 96° at MDW on Saturday.

The SPC is too hung up on that struggling MCS across S WI and N IL.

Main focus will be south near remnant outflow, which is partially washing out to the far west in IA. E IA into N IL will be more of the focal point for new development this afternoon.

Holy cow, what a storm!   This reminds me of the derecho.  It briefly poured half-inch size hail, then 70 mph wind blasted through.  I couldn't even see the houses across the street.  Thankfully, our hail was only half-inch size.  A spotter only a mile away reported ping-pong ball size.

debt repayment has been completed.

final total paid...5 years.

ula vulcan rocket launch was apparently visible overhead for all a short time ago.

Topped out at 95° at ORD and 94° at MDW on Saturday. On Sunday, MDW hit 92° (ORD 89°'d).

It always amazes me how much of a difference there is for # of 90s pretty much every year between Chicago and Madison. Madison is only at 8 for 90s so far this year. Obviously the UHI is a major part of that, but still such a stark difference over only ~85 miles in latitude.

UHI isn't as big of a factor as you'd think it is.

For example... RFD has is sitting at 18 days and ARR is sitting at 21 says. 3/4th of RFD is surrounding by open land and corn fields. ARR is in an entirely rural area, fully surrounded by corn fields. MSN is actually situated in a better location for UHI effects that either of them, but, does have the smaller lakes to the SW/S too contend with.
