So Kmox is calling it a derecho, is that correct? Still no power, and heard Waterloo & Millstadt also. Charging my phone in my air conditioned car.

A derecho is usually several hundred miles for distance tracked, and usually over 100 miles across, but generally no fewer then 50 miles. This was the work of a series of a supercell(s) pulsing (developing/maturing/dying/recycling) creating a nearly continuous line of downbursts/microbursts that happened to travel in more or less a straight line. As soon as I saw the winds on the velocity radar clocking 80-100kts I knew something was up, but there wasn't much if any rotation so a tornado is unlikely the cause. |

A derecho is usually a larger complex than this compact cell/cells was but it appears to fit the definition. "The storm is classified as a derecho, according to the FOX Forecast Center, because it produced straight-line wind damage over a span of at least 400 miles with wind gusts over 60 mph. Wind damage reports from Thursday's storms stretched more than 500 miles." Link to article Clicky |

The storm cluster that hit SW IL yesterday was not a derecho...but it was a nasty storm for sure |

Today looks potentially volatile with strong wind shear in place, but debris clouds and somewhat meager lapse rates are going to limit destabilization somewhat. The outflow from the overnight cluster has settled across SE MO and will become the northern bound for the stronger storms later today. How far N that boundary can retreat in the biggest question...currently it's sitting S/SW of the Metro. It looks like strong wind gusts are the biggest threat today.

Just drove through Nashville,IL. It’s a mess. Trees on houses. New construction near the school flattened. Barns and silos down. Corn still standing.

I have doubts on severe weather. Lots of clouds. I bet the enhanced risk gets removed from the metro

The sun has been out (almost full sunshine) for about an hour and a half over here. I'm grateful I missed the main storm to my S yesterday evening, but around 11 pm another storm came right into Salem with 50-60 mph gusts easily..I'm not sure if it was t-storm warned or not because I was in bed and didn't feel like charging up the phone. I kept power thankfully, but numerous smaller limbs are down and a few bigger ones although no major damage like the unlucky folks to my S/SW yesterday evening.

I agree I spoke to soon. I alomst wonder if a small higher tornado threat will be in the metro because the boundary may make it it 70 or just north, and sun is coming out in the metro as clouds are breaking

New Meso Up Looks to be setting up to the south and east of me today at the moment. When I refreshed the SPC page it looked like the Slight and Enhanced Risk dropped a touch south also. Edit: Awesome, AI didn't get me.

Does this look to stay south of metro. Or will more fire in the metro today. Just hoping for some rain

Suprised to see the watch including the metro I was too. My weather alert radio went off and it said "Unknown" Check local TV.  ?? I had never seen that before. So I looked on STL NWS and seen the Watch Box. I'm surprised it is as far north as it is based on the Meso Disco. No severe, just some good soaking rains. |

Clear blue sky with sky high humid and temps jumping. It’s not surprising they pushed it north, plenty of juice in the air still

Suprised to see the watch including the metro 2-3 rows of counties highlighted to the north beyond the polygon...kinda weird but obviously the focus looks to be south of the Metro. SPC shifted the hatched wind region well SE and added a 5% TOR outlook near the outflow across S IL |

Pretty well-defined disturbance across SW MO lifting NE...going to be plenty of lift developing for storm initiation over the next several hours. The Metro is still in the game...but it looks like SE MO into S IL is the prime zone where the airmass is pristine.

Definitely another prime setup for wet microbursts and swaths of intense wind
