Green Sky Chaser

19 May 2011 Chase Log

Target Area: Pratt, Kansas

Chase Area: Bust - storms too far away

Observations: thunderstorm, mammatus, and lightning

Distance: 550 miles

Time: 11 hours

Chase Team: Jeff Makowski, Esther White, and myself

SPC Convective Outlook: Moderate Risk (Click to see SPC products, data, and storm reports)

Chase Setup: A trough was located near the Rockies, a surface low in west central Kansas, a warm front stretching eastward through central Kansas, and a dryline stretching southward. Good instability and bulk shear of 40-60 knots suggested supercells were possible for west central Kansas into northwest Oklahoma.

Chase Log: Another disappointing chase day. We headed up to Pratt to hopefully see some supercells around the triple point. There wasn't much convective inhibition, but there wasn't much forcing, so we wanted to get close to the boundaries.

Unfortunately, we wound up in between two areas of supercells and tornadoes, in southwest Oklahoma and north of I-70 in Kansas. We did at least get to experience some heavy rain and lightning as we came back through Oklahoma City, from the storms that had formed in southwest Oklahoma.

We weren't the only ones waiting for storms in Pratt!
