5/8/09 NOW: AR/MO/KS/OK

2 more fatalities being reported in Butler Missouri where a tree fell on a car, catching the car on fire and killing the 2 occupants. This deffinately appears to be one of the more intense derechos in recent years. Up there with the Memphis derecho a few years ago, but on a much more widespread area.
 
Derecho on NEXRAD

I looked at the current NEXRAD radar of the derecho that passed thru So MO. It has pretty much fallen apart and has a low pressure circulation at the top. Interesting storm structure. Reminds me of a huge sunflower plant with its head bowed over and being pulled out of the ground. :)

Can anyone say MCV? Especially when the RUC MAs are putting such a bullseye of vorticity over it.
 
The term 'inland hurricane' appears in the meteorological literature for an especially strong derecho with the structure we are seeing today. It seems apt.

Local NWS offices continue to issue tornado warnings around the 'eye' (N of PAH) as it moves east.
 
The derecho appears to be slightly weakening based solely off the KPAH velocities getting broader and the "eye-like" feature opening up ever so slightly. Still though, one of the more impressive derechos I have seen in quite some time.
 
@Larry or any others,
thats a radar image from CoD website. Would it be possible to get archived images for whole day today, of any state along path of this derecho? I know I can get them from NCAR website, but what about the CoD graphics/images? Its much more impressive look over the larger systems.

For me, thats a classic MCV feature on satelites. Its incredible what have happened with this system since I was watching it from its birth in W KS. I feel sad hearing it caused several fatalities...
 
Mods: Please move this post at your discretion. Since this is 'Now' thread, I felt it was pertinent...
NW corner of Iowa/N Clay Co IA had a small tornado reported to the NWS. I talked on the phone to the EM of Buena Vista Co and told him that the NWS has issued possible SVR thunderstorm activities extending from Sioux City IA over to Spencer IA were possible this afternoon and later. Looking weaker at this time. If any change in these conditions, I will report findings.

Sitting in Ardmore waiting for the cap to break here. Looks like we're actually caught between the two areas of development (cells going up on the dryline in Texas now). Those cells are headed east right into the DFW metro area, which is not where I want to be chasing, so we'll stand pat right now and hope for development further north. Higher LCLs down there too; I'm less optimistic about that area than I am up around the Red River.

Storms are rapidly firing ahead of the front/wind shift east of Abilene up to about Jacksboro. RUC showing nearly 4000j/kg CAPE in the area. If nothing else these storms should at least drop monster hail.

EDIT: Mods- can we also add TX to this thread please.
 
There's no cu out ahead of those storms firing in TX right now. LCLs are much higher down in that neck of the woods. Meanwhile, winds are easterly in Jefferson county, and southeasterly in Love/Carter Counties. backed flow with about 87-88/74-76 has me encouraged about this area.

It's tough not to bite south at this point, but latest visible satellite looks like the cu is a bit healthier looking in the past few images.
