Oklahoma Severe Weather Discussion - June 2013

[Bunty]

Bunty, don't knock it. An inch of rain isn't something bad with June on the horizon. From the way it's looking on radar, you could still get more tonight.

Yeah, you're right. There's some sudden new builds directly approaching Stillwater. It's quite a volatile situation.

[bchris02]

News 5 and 9 both said there could be severe weather again with the storm next week. I know this round we just got through didn't look to be as bad as it was until at least Wednesday. Is it possible we might have to do this again next week?

From what I have heard at this time it’s not expected to a high end threat…
But I suppose that could change.

[ou48A]

Per CH 9…. last night’s tornadoes / storms left 5 dead, about 50 injured and over 103,000 without power.
Yep, that’s worse than the flooding.
On edit: 5 are reported to be in critical condition.

Go back and ready my earlier posts in this thread - I already addressed the severe risk coming up.

This flooding could possibly go down as the worst in OKC modern history. This will rival and probably pass the N OKC / Edmond event a few years ago in June.

My house flooded, about an inch of water, and a lot of my stuff in my carport washed down the street. Sucks but My dogs and I are safe and that's what counts.

[pw405]

I've just learned that a friend of mine may have been among those that died. How can I confirm this?

Rainfall totals from last night.

N OKC, ~7.5 inches

S OKC, ~7 inches

W OKC, ~5 inches

E OKC, ~7 inches

There are some embedded 8 inch amounts throughout much of the city - especially eastern sides.

N OKC, ~7.5 inches

S OKC, ~7 inches

W OKC, ~5 inches

E OKC, ~7 inches

I would believe it. The pictures from downtown are just insane.

My house flooded, about an inch of water, and a lot of my stuff in my carport washed down the street. Sucks but My dogs and I are safe and that's what counts.

I'm sorry to hear that But also glad to know that the important things are okay. We're trying to remember that here as we dry out.

Upside -- it is truly a beautiful day. Sucks that we had to have a night like last night to get a day like this in June, but glad to have it.

I hope not... thoughts and prayers their way

US National Weather Service Norman Oklahoma


Reviewing data this morning, it looks like our tornado warning for the El Reno tornado was issued 19 minutes before the tornado developed. We'll update that number later today as we continue to analyze the data.

[adaniel]

Hope everyone is safe! Im on vacation in Philadelphia and have been watching everything from afar. Im a bit nervous about the serious flooding I saw in downtown. Does anyone know how the midtown area (11th and Walker) faired?

we got very little dampness in the rooms that usually get water in them. we got almost 5 inches in my rain gauge in northwest edmond, and i think what saved us from damage was that the rain came in waves, and wasn't a relentless onslaught of heavy rain.

so no cleaning up for us luckily, but sorry for those of you who do have to.

Isn't that area kind of sloped? I bet you're fine.

It looks like Tuesday maybe the biggest severe weather threat day?

Does that sound right to you?

ou48A, You do know that flash flooding has little to do with your elevation and far, far more to do with the built environment? Impermeable surfaces dominate, and continue to dominate our cities unfortunately which means yeah, even houses that are not in any flood plain, can easily flood. 10" of rain in any populated area is going to create flash flooding well outside the scope of any documented flood plain. "biblical" in your words I guess, but not really.

Exactly. Great post Sid. Where I'm at I've never had to deal with significant flooding of the traditional sort. Now what I have had to deal with is the way they have our street set up, the water flow - if heavy enough - will actually hit the curb of my driveway just right and funnel right into my garage and front yard. That's not something you can really anticipate until the water starts rushing down the street.

If anyone received damage last night, please be sure you submit a report so the investigation can be thorough by the NWS...

Submit a Storm Report

[venture]

Another Update...

Survey teams have found EF3 damage in several spots west of Highway 81, and southwest of El Reno. They will continue to investigate other areas along the path through the afternoon!

I like this snippet from KFOR

With the near-constant severe weather over the last 12 days, we are in need of a break, Oklahoma. The good news: it appears we are going to get it. Although we may have bouts of storms next week, signals don’t indicate severe thunderstorms or potential tornadic activity

Yes I’m well aware of those facts and believe I have accounted for them. My yard slopes away from house at an angel that could easily accommodate a 20+ inch rain over several hours.
Most of the homes in my neighborhood have been built well above street level but even here I’m higher than most other homes in my area. There is a very limited run off area that goes past my house in the street. I lived on high ground as a kid but I saw way too many others living in flood prone areas. When it comes to flooding I did my best to learn from the mistakes of others and it really is something you can anticipate if you learn about flooding.

What do the green circles indicate? My parents' house were waaaay too close.
