MKX with this nugget in the HWO...


.DAYS TWO THROUGH SEVEN...Friday through Wednesday

There is a small chance for thunderstorms on Friday, and again
Saturday night and Sunday. Thunderstorm chances return next
Tuesday and Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed this afternoon and evening and
again next Wednesday.

Highly unusual for them to imply possible spotter activation nearly a week out, especially in a nondescript, low-predictability summer ridge pattern like the one we're in. The GFS does show some actual deep-layer shear getting into the region mid-next week for a change. Or, it's possible somebody was just bored.

Nice...definitely getting into ring of fire, possible derecho, season with that potent e-w ridge over the CONUS. Just looking at the overall pattern, you're going to have some faster mid-level flow with how strong the ridge is and any energy that runs over the top.

CRAZY tornado in Minnesota yesterday! This is some of the most ridiculous tornado footage I've ever seen. 

 

This might be the best drill-bit I've seen, and at a close range! Was this TOR warned? Like too many others, the footage inexplicably cuts off when its clearly still in progress, my God...

Another view of the tornado above from Scott Peake.  Make sure to override the settings (that many times defaults to a lower res) and choose 4K quality.  The final 20 seconds or so is truly remarkable.  What this and other vids like it show is the extreme acceleration of wind at a given point as the vortex propagates through.  The extraordinary violence of such acceleration of wind, combined with rapid changes in wind direction is what has to be one of the most damaging aspects of any tornado.  It's not just peak wind speed and flying debris.

Love the cracked window visible at 0:25. Scary stuff, but definitely one of the highest quality tornado videos I've ever watched. Something about this one kind of just makes the scale and concept of tornadoes that much more tangible to me. Thanks for sharing.

The threat around here today looks marginal worthy at best, and even that might be too much.

Looks like that MCS currently in NE IA/SW WI is riding the instability axis, and could dive SE through the DVN CWA and into C IL...if it is able to maintain over the next few hours.

It has maintained to a degree, but nothing significant as of yet. Shall see if it perks up moving into IN this afternoon.

Otherwise, looks like a loose complex taking shape in MN will dive SSE, into the DVN CWA by this evening.

Can see the stalled remnant outflow boundary just to my south with some agitated cu bubbling up.  Looks as if it could pop into a storm in a short while.

Was sort of fun watching that large updraft to the northwest this morning die away and leave a large orphan anvil canopy with mammatus.  The left (southwest) side of the updraft looked very impressive for awhile when it was first visible on the northwestern horizon.  Would have loved to get a time lapse of that evolution.

Yeah, that outflow boundary from noonday storms around Chicago metro might be strong enough to keep the nw/se axis of svr storms this Sat. eve a bit sw of Chicago area proper.  Will have to see what happens.  But mid week does look like a ring of fire scenario around here as has been stated.
