A few impressive storms today, currently the best one looks to be right over Omaha. The NWS in Valley just measured a 77 mph wind gust with the storm and velocity was showing up to 90 mph headed towards them, discussion via the NWS indicated that the sirens may sound in town for the extreme winds.

New updates from the NWS estimated 80+ mph at the NWS office...

Here at my office at 113th and Blondo we are running on generator power. Power is out in many areas and we have lots of tree damage. I would estimate we had around 80mph winds here at the office and it was literally like a hurricane. The wind driven hail has cause some siding and roof damage as well. I will update more as I know more, things are kind of confusing as you can imagine. The gust front was incredible.

EDIT: also traffic lights have been spun in the ground and are facing the wrong directions near 120th and Maple.

Between 7:05 and 7:15 a weak tornado touched down in Warren county, IN near Pine Village. It was associated with a large supercellular storm that slowly intensified as a line segment developed to the south. Radar loop supports the tornado as the storm just sat and curled up with a notch and then completely gusted out in the next frame.

A friend said he saw a rain-wrapping funnel come to the ground along 55. Tornado warning wasn't issued until 7:20, storm was severe warned.

May want to add Indiana to the thread title...

Wow..what a cell the swept through the Omaha area ! Nice Bow segment and Velocity image showed 85+knot winds..Although the damage and power outage really sucks..hopefully no serious injuries.
Another small but powerful cell SW of Desmoines earlier had a V shape for a while..most interesting.
Storms moving East and ESE in Iowa now formed into a line..in this environment should see more high winds in the stronger cells and front plows eastward..should be interesting to see how this develops tonight..

Check out video..

Fatalities

Somber news from across the river in Council Bluffs: Two fatalities now being reported by KETV Omaha in West Council Bluffs. A giant tree fell on their car and killed two and seriously injured a third occupant.

We're all aware of the strength of storms. It's too bad I can't convince my family and neighbors of this fact. I was outside trying to film the shelf coming through when my cul-de-sac neighbor wanted to come over and chat about it. I said he needed to go back inside as this thing was gonna start blasting us any second. He kinda laughed it off. Then sixty to seventy mph winds started to hit and he took off running.

67 mph damaging wind gusts in Sheldal Iowa at 7:15 PM, from the MCS now moving through the rest of the state - I was near Sheldal under the highest VIL and caught 56 on my anemometer, along with pea-sized hail (thank goodness it wasn't bigger in those winds). Tree damage reported in the Slater/Shel area.

This occurred approximately 45 minutes ago, and the cell in particular is currently just past Vinton, Iowa. Craig Maire is reporting very strong winds there, gustnadoes a-plenty, and a picturesque shelf cloud, and is soon expecting the hail currently indicated over the area.

Updraft still is occurring in the stronger part of this line, as dictated by the VIL on radar, and the storm should maintain itself until the Illinois/Iowa border and possibly a bit beyond, as indicated by the MCS Maintenance composite on the SPC Mesoanalysis page.

A classic supercell has developed on the KS/OK border slowly moving SSE into Alfalfa county! Has a mean core with hail to baseballs. I'm guessing it has some incredible structure it looks like Brandon Ivey is making an intercept now.

A TOR has been issued for the Iowa/Missouri border. SRV1, 2, and 3 all show decent juxtaposition, and with LCLs of 1000 to 1250 as shown with the most recent RUC modeling, a tornado could definitely be possible out of this storm. This section of the line is currently located just to the south of Centerville, Iowa, and is trucking along at a very fast and dangerous speed nearing 60 mph.
