3K NAM gets a little frisky with the MCS over southern WI/northern IL overnight Monday-Tuesday, and fires up another one Tuesday evening.

Latest MKX AFD... Sounds good to me.

Yeah, it was not good. Sent from my Pixel 4a using Tapatalk

Showers made it into Dane County on fumes, no lightning left.

So what's limiting the severe wx chances, given that we're in the W/NW flow? Usually this time of year it's massive ridging and no shear/dynamics.

Some of the anomaly maps being posted really demonstrate the capricious nature of convective precip, very tight gradients between the haves and have-nots. Sent from my Pixel 4a using Tapatalk

Lame, they split around Madison. Warnings in Iowa/Lafayette, and northeastern Dane.

93 at Madison. Mild. We're still forecast to hit 97.

Goes to show, a climate stat geek I am not.

Here's one for the climo stat geeks: Any summer high temp records left at any of the major Midwest/Great Lakes stations that don't belong to 1988, 1995 or 2012? Sent from my Pixel 4a using Tapatalk

Didn't we have one of those in 2020? Both in terms of an actual warm-core low (Cristobal) moving through, and then the 120-140 MPH gusts with the derecho in August?

Same, except I was on my way back after busting in Iowa. Nothing I was on really did anything, except for the cell becoming severe warned as I was coming through Verona and almost home. As I'd feared all the good action was up in the woods, and even that didn't last long in terms of significant/classic supercellular production. That signature near Oakdale around 21Z was gnarly, though. Appears Mauston narrowly avoided a major hit, as well. At Barneveld just off 151:

I'm in Oelwein, IA hoping to jump on the cells as they mature. Sent from my Pixel 4a using Tapatalk

I'm seeing Madison snuck in a daily record by 1 degree at 96. @madwx Sent from my Pixel 4a using Tapatalk

Had to pause at that one for a moment. My wife is a public child welfare social worker so CPS automatically reads "child protective services" to me. Sent from my Pixel 4a using Tapatalk

Looking ahead to Wednesday...00Z HRRR and 3KM NAM are in...both agree that the unchaseable Northwoods get rocked (again) but rather different solutions for southern areas, naturally. Looks like temperatures could still be hot enough that LCLs will be an issue for threat except perhaps if moisture pools along a boundary.

Beastly supercell going through the Ft. Wayne/New Haven area right now, fortunately for them like all the others today it seems to be spamming RFD surges preventing the low-level mesocyclone from really wrapping up, but a significant wind and hail producer.

Unusual to see tornado warning text (not sure if I've ever seen it, even on a QLCS) explicitly mention the straight-line wind threat as well. Was fully not expecting this this evening. Thought once the WI cell moved out over LM that was it on this side, took a nap after I got home.

Nice to finally see (roughly, rotation nowhere near as strong obviously, and fortunately) what Plainfield would have looked like on NEXRAD after all these years.

Leaving my parents' house in Stoughton around 3 PM I could see 2, sometimes 3 CGs hitting at the same time straight ahead of me as I drove north on County N to the I-30/90 interchange. Of course, it stopped/moved on as soon as I got my phone set up on the dash mount and rolling video. Drove through the southern edge of the RFD region with a quick burst of near-blinding rain. Lots of leaves/small limbs down all the way down the Beltline Highway (at various point some combination of US 12/14/18/151) to the west side of Madison where my apartment is. Some medium limbs down on High Point Road but that's the worst I saw.

Velocities appear to be picking up with that cell, outside the southern edge of the warning polygon. Sent from my Pixel 4a using Tapatalk

SPC being appallingly behind with the SWODY1 again.

Green County, WI warned for a hailer. 50 MPH storm motion.
