November 11th-12th storm system

DVN going to cyclone's hood

 

Saw some decent tree damage on the way to work this morning.  A large tree along route 92 was completely uprooted.

 

Made a brief radar loop of the two EF-1 tors.  The Geneseo circulation passed very close to this area.  Luckily these things were pretty brief.

About 45mph was the highest wind gust here. Winds have kicked up a bit in the last hour again. Ended over the white line a few times on the way home. Saw three power poles snapped about 3-4 feet above the ground near the state line. Lines are still attached, but hanging precariously close to the roadway.

 

Saw this picture on Skilling's page just now - from last night.

Cool

This image is getting passed around locally about obs at the DSM airport yesterday.

Comparing the time the tornado started to my pictures and location, seems like it was the same one that hit the airport. Haven't seen a full tornado in person yet but this is the closest I've gotten. Also got some video.

Posted this around midnight the night before the event earlier on in this thread.  Pretty astounding to see the main areas that were hardest impacted by severe only 14-18hrs later were still well north of the main moisture axis.  Most of Iowa was in the midst of a rather cool, almost winter-like night, and less than 18hrs later had developed conditions that were able to support nearly a dozen tornadoes.

Makes you wonder how forecasters, say, 100 years ago would've done with the forecast...how well would they have anticipated something like what happened.  People bash the models, and they are annoying when they flip flop and have wildly varying solutions, but there's such a big advantage nowadays.

Yeah no doubt.

Filtered reports.  Extremely impressive considering the lack of instability.  Extreme dynamics made up for what would normally be considered laughable instability.

Here's how this one compares to the one that occurred almost 10 years earlier to the day, November 12, 2005.  We may fall short in terms of number of tornadoes (though surveys still ongoing), and 2005 had 4 strong tornadoes, but yesterday's wind event was much better compared to 2005.  2005 did have more activity farther south in MO/AR, which this one did not.

What Cheer? Pretty odd town name.

Lol, wonder if it's a town of pessimists.  I used to live in Gnaw Bone Indiana.

 Had some decent gusts here, maybe 45 - 50.  The old house creaked a few times, not as bad as I had expected.
