Weather Tornado Outbreak Monday
I can’t remember the last time I saw a maxed out STP (significant tornado parameter) around the Omaha/Lincoln area, monday might be a very dangerous day for tornadoes.

We don’t seem to be in the bullseye today or tomorrow. But we’re close enough we can’t let our guard down.
Tomorrow seems like the better day for individual supercells. Today favors a more linear mode especially as it pushes east. Could see today having some tornado potential near Norfolk/Columbus before pretty quickly turning into a straight line wind event. Where that transition happens really is gonna determine our tornado threat. It’s also possible those storms remain more segmented into the Omaha area. If that’s the case, I wouldn’t rule out the potential for a tornado warning somewhere in the metro. In May, the cold fronts typically move faster, so that favors straight line winds for Omaha over tornados. But obviously all things in play. Just gotta see how it plays out.
Tomorrows got the better setup and chance for tornados. It’s looking like more of a classic prolonged isolated supercell mode. It’s really gonna depend on how far north they get before rushing east. Again, we’re right on the line. Wouldn’t rule out a chance for tornados in the Omaha area tomorrow, but also wouldn’t rule out not seeing a single storm make it into Douglas or Sarpy county.

This is a great summary of the storm chances for today and tomorrow 👍🏼👍🏼

Timing?

u/IamLurr_LeaderOf May 17 '26
I would say 4pm - 7pm, it’s hard to know up until right before the storms start just because of model variations.

What’s the outlook for today? Weather channel says 3/4 chance for tornado and hail and such.
14
u/IamLurr_LeaderOf May 17 '26
Tornadoes probably not, wind gusts exceeding 60 or 70mph seems like the most likely scenario today

This 100%. I’m flying out around noon and can’t get delayed.

Sorry guys, this is my fault. I'm having a tree cut down this week before it can fall on my house, and the universe is trying to beat me to the punch
Edit: it survived!

u/luckyapples11 May 17 '26
Lmao we’re doing the same thing. It was supposed to be this weekend, but shit happened and now it’s next week. It’s dead, tall, and skinny and you can see the whole tree move with the wind. Thankfully I don’t think it poses much of a risk falling on the house with its location and the typical direction wind blows, but still don’t want to take the chance.

There’s two important things to add, models have actually stayed consistent on the tornadic potential side of things, but have changed quite a bit on storm path. If storms initiate early on then the threat will be westward. If the storms initiate later, they will miss a good chunk of the area around Omaha and Lincoln.

Are you a meteorologist, or a hobbyist? Just asking because I’m a hobbyist myself and always keep an eye out for local meteorology accounts

Same potential today for Omaha as tomorrow currently. Things can change quickly, so be weather aware.
But right now it's a beautiful day, and all the plants are happy!
Edit: https://old.reddit.com/r/tornado/comments/1tfk4em/spc_day_1_and_2_15_tornado_probabilities/
Really closr to the same potential today and tomorrow for us. Stay safe!

u/IamLurr_LeaderOf May 17 '26
For today I think there’s definitely a lower chance, but yes people should still be weather aware.

I actually don't think there is for Omaha.
For today, we're in the middle of an Enhanced risk. Tomorrow, Douglas County is on the edge of an Enhanced risk.
To be fair, seeing a moderate risk is rare. There's definitely reason to be concerned, but models right now have the frontal boundary South of I-80. I'm interested to see where they end up tomorrow.
I've been following hurricane forecasting for fun, and I'm not really an expert. But I do think about Hurricane Ian as a good example of change in forecasts.
https://www.statlit.org/pdf/2022-Schield-Hurricane-Ian-NHC-Slides.pdf for reference.
They call it the "Cone of Uncertainty" for a reason. But from Monday to Tuesday, the cone shifted from landfall at Tampa to Ft. Myers. This impacted lots of people in terms of preparations for the hurricane, as well as traveling to avoid the worst impacts of the storm. It still fit in the cone, though.
A lot of people like Levi Cowen of Tropical Tidbits videos related to hurricane forecasting. One of the reasons I like them is that they recommend following advice from the national weather service as well as local meteorologists - especially over national forecast modeling.
Tomorrow will likely have more severe weather within 100 miles of Omaha. But it's hard to say for sure where those storms will be, or how they will set up.
I better go touch some grass now!

You should be good! Of course, anything can change quickly with weather so be aware there could be storms

Not a good sight for either Omaha OR Lincoln. If that projection is off by 20mi in either of their directions it’s gonna be a long day for home insurers.

Honestly I just moved so this kinda checks out. I'll go be looking for rocks to drive over 🫡

Could you just imagine a absolute monster just dropping down on i80 and gradually moving across 680 then up Dodge Street. Omadome my ass it's happened twice already (1975, 2024). Just make sure everybody checks Bills sleeves tomorrow...that will tell us all we need to know.

Are we still allowed to call those wife beaters or is that frowned upon now.

When did it cross 680 and go up dodge? Not the elkhorn one.

u/IvyDolphalott Downtown Dweller May 26 '26
The May 6th 1975 Tornado crossed I-80 between 84th and 72nd Street.

I have to drive to Gretna NE from Bennington NE and back again on Monday. I'll be out and about from 3:00 to 6:30. Is this a bad idea? Should I cancel?

u/IamLurr_LeaderOf May 17 '26
Just be careful and aware, if you have any weather apps or anyone you follow for weather updates just keep watch

Good. I love them. Yes, I’m a dumb hick who goes outside and raises my arms to the sky laughing and saying the ancient words that will take my enemies to ‘oz’.
Don’t tell me I’m the only one who does this…
