5/8/08 NOW: KS

He's back up. Showing two HUGE mesos - looks like a new one is forming to the east of the occluded one.

:edit: wall cloud starting to condense under the new meso. Ever so slight rotation. At least all 7 seconds I saw!

Storm looks to be moving into mid 50 to high 50 degree dewpoint air. That should help.


Problem is he is west of the hook and its starting to rain wrap. There could be a big tornado inside that hook just NW of Jetmore and Lou will never see it. Very well defined inflow notch NE of where Lou is siting. He needs to move east quick not only to get better visibility but to get east of storm before it cuts his route off. After that he has to either punch the core (not a wise choice) or drop south then move east and back north.
 
Stuart Robinson's stream is back up.

These are some very impressive storms today. With the positioning that I am seeing on the cams and Spotternet, there should be some great pics coming later this evening.
 
Wow. The 00Z DDC RAOB has a large, sickle-shaped hodograph (southerly flow of 40+ kts at 500m agl) that would be impressive even for an NE-moving storm. I'm showing 0-1km SRH of about 550 m2/s2 given the observed motion of the supercell just south of due east... ridiculous. It looks like convective inhibition is becoming a problem though, with about 60 J/kg MLCINH already observed on the sounding, and surface temps now falling toward 70F.

WOW... if you forget about the 58 Td that is one of the more impressive soundings so far this year. Almost as cool as 5/2/08 OUN 00z

The hodograph definitely looks nice, but it is a bit deceiving with the high LCLs and LFCs. There is also such dry conditions above the surface that I would expect significant cooling with any downdraft, and cold RFDs dont have near the tornadic potential of warm RFDs. I'm sure this is why many of these storms would hit a boundary, have a very quick spinup of strong rotation, but then quickly die as the cold pool overruns the inflow. Its too bad we didn't end up with a lower dewpoint depression today, the shear could have made things very interesting, indeed.

Yeah... we just needed 5/2/08 OUN's thermodynamics with today's DDC hodograph!

I'm strongly starting to suspect that the supercell directly impacted the low-level flow sampled by the DDC RAOB, particularly since it only passed 20nm north of DDC. (Even by 01Z, the Vici profiler is still only showing 30kts at ~1km agl, whereas the DDC RAOB sampled nearly 50kts at 1km agl... and none of the short term model guidance was forecasing low-level hodographs that large.) If so, pretty cool direct sampling of the enhancement of SRH right in the inflow of a supercell.
