May 18 proved to be somewhat of a success. The forecast panned out and we were able to see a high based cell which had very broad and weak rotation a brief period of time. It had supercellular form but I'm a little reluctant to call it a supercell. We did call the chase off a little early since the cell did not show much promise and only went on to produce 1" hail, thus we were able get into position for today.

Although at the moment I am still a little uncertain as to where the final target will be. There appears to be two areas of interest right now and that would be the Beatrice, NE area and western Oklahoma or near the Alva, OK region. There are two reasons for this. The upper dynamics looks to be better for the SE NE/NE KS region with the upper trough taking on a little more of a negative tilt and lifting off more to the NNE along with upper support from the jet at 250 mb aloft. At the same time the upper flow shows descent curvature as well which may prove to help enhance the potential further to the south.

Moving down to the lower levels the 850 mb flow is pretty good out of the due south and is actually favourable for both locations, what is the issue is how fast the cold front will sink south and overtake the dryline. This along with the fact that the shear vectors looks to be more perpendicular to the dryline/cold front intersection and that there looks to be a greater chance for isolated cells along the dryline (see image below showing sfc-500 mb bulk shear) in western Oklahoma, I think we may head to that region but will have to look over more data in the morning since I'm not ruling out southeastern NE yet.
