Pratt KS here we come!

It's official; we're targeting Pratt as our epicenter of convective mayhem today. The models and local forecasts are all calling for the cap to break between 1300 and 1600 local time today in southern and central KS, and the convective potential and shear values are favorable for supercells during the early stages of today's events. Toward dark the storms will likely congeal into a squall line and then into a mesoscale convective system (MCS) that will cover a broad area with heavy rain, wind, and lightning. That means we'll probably cut off the chase near dark and scoot south to Oklahoma City where we have hotel rooms awaiting us for a quick nap before getting a relatively early start tomorrow for the run to the Dallas/Ft Worth airport.

Meanwhile this is a photo of an earlier version of a wallcloud on the 13 May storm we were tracking southward in Oklahoma. I've enhanced it to show the updraft as well as the gathering scud underneath. This view doesn't show the striations we noticed that indicate a rotating updraft, but they were there.
