I will be starting my 5 day chase trip on Sunday. Not gonna go real in depth right now because I'm frickin tired and to be honest I dont have the best idea of what's going to happen on Sunday. However, there will be some sort of boundary slowly moving across Nebraska. While this same boundary may affect SD/MN/IA, the best shear looks to be farther to the southwest and a very juicy atmosphere with MLCAPE values nearing 4000 j/kg across south centra/southeast Nebraska as per the WRF. Another problem farther to the north/northeast is that surface winds will be running more parallel to the boundary. Not completely sure what kind of boundary we are talking about, looks like a slow moving warm front but who knows. Anyways, the only real problem is the cap. I think the new WRF might be a bad run in terms of CINH as it breaks it down rather weird IMO. Also, I personally think earlier models may also have been a little aggressive in breaking down the inhibition with a large swath of no CINH across NE in to KS. Another strike is the upper winds are not ideal, but with decent helicities and strong to extreme instability, I think it could be a fun day. Models are still going back and forth about where exactly the boundary will end up but that will be a chase day call anyway. Regardless, I will out Sunday across south central Nebraska or north central KS. Be sure to watch my stream at tornadovideos.net and wish me luck on my first "chasecation"! Will be out chasing Sunday thru Thursday.
