Ground Scouring Posted May 12, 2014 Share Posted May 12, 2014 Maybe the outflow boundary from the cell to its SW will cut off inflow to the Omaha TVS. I'm skeptical that a violent tornado can come out of this before it passes closest to downtown Omaha, but it will be close. Environment is favorable. Unfortunately the next several miles are through populated areas, but fortunately the cell is so messy that nothing significant may come of it.

Also looks like it may be veering to the northeast slightly. We'll see what happens, it is quite the HP mess now. Link to comment Share on other sites More sharing options...
soonertrey Posted May 12, 2014 Share Posted May 12, 2014 Seems like the rotation is trending more to the north than previous scans. May miss Omaha proper as it looks now. Link to comment Share on other sites More sharing options...

Right now the environment down in KS looks more favorable for non-HP / classic supercell structures, fortunately. Anvil-level winds are weaker over the Omaha metro area. I think Omaha proper will dodge a bullet. Link to comment Share on other sites More sharing options...

KS is certainly becoming more interesting. If storms don't line out then we could see some nocturnal tornadoes as LLJ continues to strengthen.

Eskimo Joe Posted May 12, 2014 Share Posted May 12, 2014 Omaha cell had so much potential too...just a meh line of wind now. But behind the initial push there does appear to be a significant slug of rain for the metro region. Link to comment Share on other sites More sharing options...

OSUmetstud Posted May 12, 2014 Share Posted May 12, 2014 My guess is that the cell to the south helped choke off the inflow. God knows we've seen plenty of HP supercells produce violent tornadoes. Link to comment Share on other sites More sharing options...

Well one thing that appeared to be happening is that the RFD was always overwhelming the inflow so that any tornadoes that developed were short lived before occluding.

OUGrad05 Posted May 12, 2014 Share Posted May 12, 2014 Glad Omaha dodged a bullet. Been texting a friend up there to keep an eye in weather today. He was right in the path but would up with strong WI do but no tor. Sent from my SM-N900V using Tapatalk Link to comment Share on other sites More sharing options...

Wx 24/7 Posted May 12, 2014 Share Posted May 12, 2014 surprised cell heading towards Salina doesn't have a warning, nice rotation showing up on velocity I was going to ask a similar question. Seems like ICT has been more conservative as of late to issue TOR warnings. Case in point... yesterday, even though the storm near Severy had several reports of funnel clouds and a couple of brief touchdowns there was never a TOR warning.

Told my buddy to prepare for really high winds. Hopefully no major damage in Omaha. Sent from my SM-N900V using Tapatalk Link to comment Share on other sites More sharing options...
nwburbschaser Posted May 12, 2014 Share Posted May 12, 2014 Any word on chasers getting hit today?

Apparently someone got hit, but are okay. Pretty stupid if you ask me. There weren't any big surprises with that NE storm. Stay out of the mesocyclone or risk losing your life.

Looks like Cloud 9 Tours got hit by farm equipment debris...not sure if they were directly in the circulation. Appears from Charles Edward's Facebook page that all are OK.

andyhb Posted May 12, 2014 Share Posted May 12, 2014 interesting. Why would you think that would be the case? Well I could be wrong on this idea, but since most of the storm was actually on the cold side of the boundary (with northerly winds to the north of it) aside from the inflow region, since the RFD was being sourced from the colder air on that side of the boundary, instead of spurring on long-lived tornadoes, the relatively colder (and thus heavier/denser) air in the RFD (as compared to a storm further south) may have made it more effective at leading to occlusion/cutting off of the low level circulation/inflow. Again, this explanation might not be correct (feel free to correct me if it is), as my knowledge of these processes still needs some work, but the northerly winds north of the warm front intrigued me in this case. Obviously, the fact that it was relatively HP from the start had a say in this as well. Also there is a report of a house destroyed to the basement/foundation earlier near Sutton from the first large tornado that cell produced.

I was a bit "concerned" earlier when I noticed the best tornadic indices were north of the warm front, as areas south of the warm front had a combination of relatively low helicity and high LCLs.
