Banded cumulus clouds over wichita

horizontal convective rolls over wichita

Anyone else catching these horizontal convective rolls (Thanks Joey!) passing fast over Wichita? They look pretty impressive right now. Visible satellite isn't showing anything due to the higher cloud cover. Weird thing was the convergence of the bands. Check it out:

Sorry if this is the wrong area. Mods move as needed.

Cool pictures! Aren't those horizontal convective rolls?

Banded cumulus

I saw that on the way to work this morning, very unusual to see and really neat!

Now that is a good transverse roll example if I ever saw one! Good job on the photos.

I live in the Wichita area and saw them as well. They were definitely horizontol convective rolls. You can still see one of them in Butler Co.(the co. east of Wichita) on radar flying east. Definitely a great sign for what could be a crazy day!

FYI: Those pics would be great for a severe weather textbook or case study on HCRs.

And the man wins a cigar. It can also suggest that bad times are ahead. Just a hint, that bit of convection that rolled into Moore OK with an F5 tube in may of 99 started at the convergence of transverse or horizontal convective rolls with the dry line.



Looking at that and the various models this morning, I have the sinking feeling that this is going to be a historic day for chasers and a bad day for innocent folks in the central plains. Sadly I am too far south and will only be an armchair spectator.

Well hopefully a mod can change the title of the thread. I'm still learning =)

Those are some pretty cool pics. I've always thought these were caused by a strongly sheared but capped environment. As they spread out the environment is becoming less capped and any storm can ingest these rolls.

Not a problem, we are all learning. An those are some darned fine pics.

Very nice pics!
During the aftermath of my first really succesfull lightning-attempt, in the early morning of 21 july 1998 in The Netherlands, I witnessed such clouds in the wake of a strong thunderstorm. At that time I supposed that they were caused by gravity-waves in the inversion caused by the outflow.
But perhaps these rollclouds on the photographs have another cause?

I couldn't see it when I checked visible and IR satellite. Maybe it was old data still on the NWS site that hadn't updated to the time I actually took the photos. That was around 730am since I was going to the clinic for a doc appointment.

I'm just curious. IRRC, the HCR's of 990503 were only visible on clear-air mode radar at the time. Were they also visible to the naked eye? I'm not in any manner implying that you're "wrong", Paul.

Transverse rolls. Something I like to see in the morning but not in the evening unless the cap breaks.

 

[Maggie Kahman]

don't they also call those "cloud streets"? Thats always what Iv been told.
