Could be looking at some action next week in the northern/western parts of the sub.

Ugh. Not a fan of this type of warning. "Possible large and extremely dangerous..." "Radar indicated rotation" It's either radar (TDS) or spotter confirmed as being "large and extremely dangerous," or you don't use the PDS designation.

I'm curious, at what level are the winds bringing the smoke in? According to the models we should be in southwest flow at 500 with this thunderstorm setup ahead of the incoming cold front.

Huh. Unless I was reading it wrong all the social media hype seemed to be for Sunday night.

Haven't seen any aurora pictures from MN/WI/IL from last night so I'm guessing the smoke busted it?

Bring on angry corn-fueled MCS season.

Pleasant, but by my standards too cool and quiescent Memorial Day weekend and most of the remainder of May on tap. If I hadn't gone to get the Arnett last weekend it'd be yet another of those springs where I'd be going stir-crazy.

I didn't realize until seeing the DAT that the nocturnal KS beast was actively producing an EF3 while I was on it north of US 54/400 between Cullison and Pratt shortly before 11 PM Sunday. The inflow was howling but the reflectivity signature looked messy from the merger and the velocity, while there was definite rotation, wasn't clear-cut "intense tornado in progress" like it had been back west of Haviland and again from Iuka to Plevna. After I got sick of the pitch black dirt roads (which didn't take very long) and got back on 54/400 eastbound toward Pratt, the lightning didn't illuminate under the base much during the time I was recording. This is the best frame I found that gives some hint as to what was going on, toward the bottom center:

More fun with timelapsing my Arnett/southern Kansas footage from last Sunday:

Booked PTO to chase this Sunday-Monday back on May 9th. Managed to get there in time for the beauty near Arnett (@andyhb was on it as well). Then, hours after I thought the day was done, tried tangling with the Haviland-Plevna nocturnal beast when it was cycling northwest of Pratt. Quickly thought better of that and booked a room in Pratt for the night just as it was ramping back up.

A little bit of early day crapvection might have actually helped the threat with this one. So unusual to see such a near-total lack of it with a setup in this region, but now the temperatures are getting too hot, primarily in Illinois where the better chance of a longer-lived discrete mode is.

That does look like a strong possibility. I'll probably head to Sun Prairie or Columbus as a starting point.

If temperatures are held down a few degrees from the HRRR soundings (which the current clouds over southern Wisconsin might help with) we could be in business. However 12Z CAMs trended to a messier mode around here. Only the RRFS still maintains more spaced out cells.

3K NAM, RRFS suggest the Sycamore area could well be in the bulls-eye.
