105 mph is wild.

URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 448
   NWS Storm Prediction Center Norman OK
   750 PM CDT Fri Jun 20 2025

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of 
     Northwest into West-Central Minnesota
     Central and Eastern North Dakota
     Northern South Dakota

   * Effective this Friday night and Saturday morning from 750 PM
     until 300 AM CDT.

   * Primary threats include...
     A couple tornadoes possible
     Widespread damaging winds expected with isolated significant
       gusts to 105 mph likely
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible

   SUMMARY...An intense squall line is forecast to rapidly move east
   across the Watch area this evening into the overnight period.  A
   potential supercell tornado risk may develop with any storms that
   develop ahead of the squall line.  A tornado risk may accompany the
   stronger and more persistent embedded circulations within the line. 
   Widespread severe gusts (60-80 mph) are expected.  Swaths of 80-105
   mph gusts are possible with the more intense portions of the
   convective line.

01z outlook is a perfect match to the track of the 1995 right turn Derecho

I was just reading into some of the old analogs. That’s a good one

Some people not really expecting severe weather could get quite a surprise if the Derecho keeps up steam

It’s been awhile for a super long track derecho. See how it plays out.

Warnings for 90 mph winds in North Dakota currently

Even this gust front got a severe thunderstorm warning with a “destructive” tag. 

It’s incredible how much wind energy there is.

I'd like to trade this ROF pattern in for a different one.  This particular one is lame AF.

Yep.  It's late June and we are still waiting for the first MCS activity of the year.  Severe season has been a dud.

Well the tree and power line trucks are gone. I swear you'd have thought we got hit by a hurricane by as many of them that were all over this area until yesterday. Took a drive over the weekend and it was pretty bad for the trees, big trees, I mean 2-3 footers, 6in-1ft limbs down everywhere. From my previous hurricane life conditions were similar to a slow approaching hurricane as the specific area around me was hammered with up to a half foot of rain so we were already flooding when that line hit. That meant the trees and the ground were pre-soaked and primed to fall if there were strong enough winds and there were. Easily close to 1 min sustained strong TS force with Cat 1, maybe Cat 2 gusts through that area. Eerily similar to how widespread tree damage is caused along the coast in strong TS's/weak Hurricanes only without a storm surge.

Been awhile since I've seen that much widespread tree damage around here, especially central Madison over into Delaware and Blackford counties. Along with the gusting "almost a D word" line there was also a significant downburst, IMO, through that area as a pre-frontal cell that blew up ahead of that line was consumed within it. You can see it in these 2 radar images from KIND's event page. The first Image, its in front of the main line as it was blowing up just SW of Marion and the second, you can almost see the exact shape of it embedded within the line just ENE of its previous position almost directly S of Marion. What was even more interesting, to me anyway, was a very small ragged "donut hole" type feature immediately behind it. That "donut hole" artifact or whatever it was passed right over my position where I nearly hit a tree as it came down. I don't think its radar shadowing or anything like you would see during a hurricane. I really think, IMO, its a radar image of a downburst or microburst (are there Sting Jets in severe lines?lol) from or enhanced by that rapidly forming small SUP out ahead, possibly from it collapsing within the line accelerating the forward "gust front" even more. I mean that thing shot up to 55kft in like 20min on Radarscope before the "Meg" line ate it lol. That's why I was chasing it. It had a rapidly lowering wall cloud, a good hail core (2-2.5 inchers reported directly under its position in the Alexandria, Summitville areas) and was just forming a nice tail/hook on radar (you can see that a bit in the first image). Back flow was ramping up into that little SUPs gut as the updraft accelerated.  Went from maybe 15 to 20KTs, more parallel flow from the SSW, then suddenly veered to easily 30-35KTs from the SSE as I got about 2 miles S of it.

I'm more than likely over analyzing it lol. It more likely the ton of very localized rain that resulted in so many large trees and limbs concentrated in that area as opposed to more spread out in other areas. I counted at least 65 entire trees larger than 2 feet either uprooted or snapped just on my 2 hour drive. North and south, where they didn't get massively presoaked there was not nearly as much concentrated tree damage though. But those radar images kind of puzzled me when KIND put them out Sunday triggering the ADHD non scientist in me 

One of the stranger storm chases I've done. Wasn't prepared, very chaotic spur of the moment chase looking out the windows, at the radar on the phone at 45 to 50mph on country roads (around Moonville IN, the worst place to chase lol), in and out of densely wooded areas along White River and suddenly dodging falling trees and sideways rain all at the same time lol. 

Whatever, sorry for the long post, I'm just out of heat therapy but it was nutz lol.

(Don't get on me about safety, y'all have done it before lmao)
