We’re finally seeing earlier and better mixing locally today.

Monday and yesterday really didn’t start mixing until later afternoon. Today it has been all day, and it looks to be more thorough now, with DP’s bouncing between 66-70° currently.

With that, today should feature the peak high temp of this stretch. Tomorrow would have a shot as well, if not for increased cloud and outflow potential.

DVN had 95 for us today.  We hit 90.

Under-mixing.

It always seems to be the issue in these set-ups.

Edit: Looks like the 0z and 12z HRRR 'only' had a high of 91, so it seems overzealous DVN was just being its usual self.

It's unfortunate that the ridge center trended east over the past several days.

We could have had a shot at 100 locally with it better positioned further west, and we also likely would have prolonged the heat wave as well prior to ROF potential.

Ignore the horrid forum upload compression, but another quality look from ORD this evening as that hybrid supercell moved in.

Again with the late city addition to the watch. Why does the SPC kept doing that; so dumb. 

i came here hoping to see this...didn't let me down.

most of the time there's watch collab, so may be the spc or lot.

Joe, since your tracking 90dF+ days each year, thought I'd look at the longer period stns on your list, and graph the yearly counts as reference. Unfortunately, MDW has a 15 yr gap.

Thanks for posting that. It gives a good visual of the trends over time.

It also reminds me that we're due for a clunker.

Solid MCV soaker today.

More tubes possible this weekend in IL. Record year for the State incoming?

Need a t warning on that Macon county cell

they got duped.

most, if not all of that, is contamination.

IWX obviously isn't bailing due to the south trend, mainly because of their thought that we are still in the game south of 30 with the warm front, as you alluded to earlier. From discussions, I got the idea that they aren't very happy with SPC's demoting us to slight, but of course they won't come out and say it, hence their post.

they might want to do another check on observations (radar, satellite, surface obs), because it is definitely over north of us24.

THIS IS OUR MOMENT 

not this time, that was a real call for a change.

Not sure if i get the EF4 tor threat mentioned on this MD for the morning convection

Actually asking. What is the effect of the tropical storm going to have on this? It has to have some impact I feel like it’ll steal some energy, no? Nobody seems to be talking about it and I’m legit asking
