Moderate Risk: 5-20-13

The Storm Prediction Center has issued a moderate risk and hatched tornado threat area for a central and eastern Oklahoma and Kansas today:



Yesterday’s chase left us in Oklahoma City, which is on the westernmost portion of the moderate risk ring. It’s a good place to be.

A glance at the central plains shows high dewpoints again, but one of the most striking features is how the dryline bends. I think I want to be southeast of that bend.


On the other hand, there is a giant outflow boundary stretching across all of Kansas, headed southeast.

The better shear is farther north.


I will keep you posted on where we go. Right now, we are going to drift south for lunch in Norman with another storm chase friend of mine. After that, I may head north to catch the higher shear. SPC seems to think these storms will go linear quickly, so catching them at their initiation and in the higher shear will yield supercells over line segments. I don’t want to get caught west of OKC and have to try to trek through it however, so I’ll have to commit to north or south.
