SPC has expanded the MDT risk a bit further southwest and now has added a 15% tornado probability area.

It is warm and a little muggy in my area. 75/68.

Very complex and difficult to forecast setup today. There's an OFB near wichita that might kickstart initiation. Ignore the CAMs, they're all over the place and you won't get much useful info from them. The ingredients seem to be there, so I'm just keeping an eye on the convergence zones and cap, as well as the special soundings today. OUN has 18Z and 21Z scheduled iirc so that'll indicate a lot further south, and I think wichita is doing at least one as well.

I see one or two strong tornadoes coming out of today.

Latest update from Norman says the cap has not changed much as of right now but will be "definitely breakable" by later this afternoon.

Current OKC sounding shows a very strong cap, but SW OK is already showing 0 CIN and nearing being uncapped. With rapid surface heating, I have a feeling OK is going to overperform significantly today even into C OK. There's some subtle convergence occurring already in SW OK where the cap is eroding, and being that it's eroding as rapidly as it is, I would have to think it's going to erode downstream as well. NWS Noman already says via twitter that dewpoints are significantly higher than modeled, which could make a cap break more likely.
OUN has another sounding for 21Z scheduled, and based on what they're saying it seems they expect initiation around that time.
Meanwhile, KS has also rapidly trended towards earlier initiation between 19-21Z. Today went from a potentially meh chase to a potentially big day with multiple targets.
Tornado watch out. 60/50 tornado probs.

Beat me to it. Seems to be centered a little west of most of the MDT/hatched area. For several occasions going back to at least 12/10/21 (which would certainly have merited it, in hindsight) they haven't gone PDS in a 15% hatched. We'll see...
New mesoscale discussion out. Mentions 80 percent chance of watch being issued for eastern KS/OK.

I wonder how far south they're going to take the watch relative to the MCD. Maybe issue one for KS/N OK and wait to see if C OK initiates?

Definitely some strong wording with the recent MCD. Potential is certainly there for today to be one of the bigger Central Plain events in recent years if the cap can successfully erode, but like with most events in this region, it's a big IF.

Interesting storm on the western side of the dryline.

Nice outflow boundary north of DDC.

I'm at work and can't really check much right now, how is the cap holding? Been a little skeptical of Plains setups like this since 2019...

You can actually see the dryline on the Wichita radar.

The cap looks to be eroding. We've already had a couple attempts in C KS. Just needs a little more convergence.

20Z HRRR.
