I'll go under with a 96 for the new hottest temp of the season. NEST shows 94 and it's usually a few degrees too cool it seems. Although the 12z NEST had MLI at 89 at 19z which is spot on, while the 12z HRRR is already 3 degrees too warm.

Nothing's gonna compare to the pine tree vid, but these two are pretty good.

Looks like a good shot to break MLI's weak sauce 94 max for the summer with this wave. Euro shows 96-97 for a few days, so we'll see. Earlier in the summer it was underdoing temps by 3-5 degrees, but now I'm not so sure as I haven't been paying much attention to it. The surface is quite dry now, and corn crops are very quickly drying out as we head towards harvest season. I'll be optimistic and go with 98 for max for the week at MLI.

Glad things are getting more back to normal there. Definitely a pain in the ass to be sure. Found the location the infamous falling pine tree derecho vid was shot at in Cedar Rapids. It's on Greenfield Street just west of C Ave. This looking back towards the house where vid was captured.

DVN made a correction to their peak gust there at DVN, from 86 to 87 mph.

I passed through Clinton Iowa/Fulton IL on Monday. Definitely not surprised to see that local area of higher wind estimate pop up as it was pretty bad. I also came across a huge grain silo a little west of Elvira that was caved in quite severely. It's right in line with that corridor of highest winds, although the NWS has 80+mph there. I'll see if I can get that pic on here. EDIT: Here it is..

Got down to 48 this morning here, which is the first sub 50 degree low since late May, and the coolest since May 13th.

I'd like to know why the rear-inflow jet seemed to be basically at ground level. I know there's been instances of long-lasting high winds, but I think that is usually over a smaller swath closer to the parent mesovortex. I read somewhere that this almost seemed comparable to an HP supercell with a powerful RFD. In this case the RFD was extremely large. We didn't get the extreme of Cedar Rapids, but I'll never forget the 1hr+ of non-stop severe level winds.

Yeah I've never seen anything higher than 80 mph in person, so it's sort of a guessing game above that for me.

That gust at 16:15 is just incredible. That had to be over 100mph. I've watched that part of the vid numerous times and the gust hits so hard it almost sends chills down my spine.

Definitely lucked out. Don't wanna see anything that super crazy ever IMBY.

Amazing. New info from the DVN page.. A swath of damage from Benton County, through portions of Linn, Jones, and Cedar Counties, is consistent with intermittent winds in the 110-130 mph range. A radio transmission tower north of Marion, Iowa in Linn County collapsed, due to straight line winds estimated around 130 mph. This speed would be equivalent to a strong EF2 tornado. The maximum measured wind gust was 112 mph at Midway, Iowa in Linn County. One storm-related fatality has been reported so far. That area where 130 mph winds were estimated north of Marion is right where the highest velocities showed up on that radar time lapse I made the other day. So it was actually even worse just north of Cedar Rapids. If that would have moved through the heart of CR things could have been even worse, which is pretty crazy to think about.

Nice map put out today by the DVN NWS.

I believe statute of limitations for warning points is 11 years.

It was 109 at 3am this morning.

Short but pretty good vid

That would definitely be an odd situation.

Impressive. It was 107 already at 9am, and 120 by noon. https://www.wrh.noaa.gov/mesowest/timeseries.php?sid=DEVC1&num=72&banner=gmap&raw=0&w=325

Incredible video. Like so many have stated, it looks like you're watching hurricane video due to the longevity of it. Besides the wind being much stronger, another big difference between there and here was how much more heavy rain was falling simultaneous with the very high winds. Here it was mostly light rain during 80% of the highest winds. EDIT: That gust at 16:17 was incredible.

Spent some time this morning making a time lapse of the derecho from the DVN radar. On the 2nd time through the base reflectivity I put the storm reports in. It's pretty cool to see the tornado reports pop up as the derecho crosses I-39 in IL.

Unfortunately we don't have any active participants on this site from DVN like in the past. I'm sure they browse the site and lurk in the shadows, but aren't members. Would be interested to see why there won't be any surveying.

Time lapse from Monday. Might take a bit for 4K to be available, as sometimes it takes an hour or so to be fully ready. Shot at wide angle, so looks best on full screen. EDIT: I left in a decent amount of footage before the storm hit to illustrate how nice and peaceful the day had been. Storm hits around 2 min mark.

Power came back on about 10am, so total outage was about 92hrs. Working on time lapse now. Made it to 88 here, but not too humid.
