April, 26th 2007 Darlinton, IN Storm

Not much to say here, low pressure setup over east central IL with a cold front extending south and warm front extending east. The cloud cover that set in around 10:30am pretty much destroyed the chance for any surface heating (much needed on this chase day). In the warm sector sbcape values were around 1000 j/kg, with stronger pockets along the warm front. Deep layer sheer was 50 kts mostly speed sheer, with 20 kts in the 0-3 km range. With the low level shear setup and backing winds along the warm front their were good helicity values. Their was a LLJ kicking in around noon or so which helped things out a little. I planned on a target in nnc IN right on the warm front. Well I waited, and stuff was starting to fire to my west in IL. Waited some more, and stuff was firing and going tornado warned in Ohio. Nothing was going on around me, nothing except for a few pulse like storms going up further south. It seemed that the whole system just skipped IN, nothing but crap was going up. I saw a tower going up to my south and saw that soon it had a decent return on radar. So I head south to Darlinton, IN which incidentally is where my sister lives.

The above picture was shot in my sisters driveway. It was crap, the outflow was cold and their wasnt much rain. I think it was trying to round out but it wasnt doing it. Im not sure but I think this was very linear. All the good stuff was in OH. Thats what you get, with weak instability, I think it was only around 1000 j/kg MLCAPE and 50 kts of speed shear. Alot in the lower levels (20 kts) would make you think of MCS systems.

Underneath a arcus cloud in my sisters yard. Almost no lightning, I saw maybe one in 30 mins
