I don't think Karen is giving energy to the system... nor taking away... i would think those low line clouds, while they look like IV lines going to the disturbance... i woud think its more of a temperture inversion/dewpoint line... where on side is cooler/drier then the other... being pushed by the NE flow.. cause a set/line of Stratocumulus clouds to form... i would on think right now that the mid to upper levels would be something that would affect the disturbance....

watching recon on TD 13... didn't see that higher of flight level winds.. they made the first pass... should be tunring back to center soon... notice that the surface center is 5nm from flight level center... so still some shear...
