Big won't do it, so we'll go marginal

Going to try my hand at a fairly marginal cold core-esque chase near St. Louis this evening. Will be pairing up with fellow meteorology student here at NIU, Heather Brinkmann. I've been eyeing this one for a few days, and at times it looks amazing, and others not so much. But, typically with a day such as this you won't know for sure until a storm pops up and develops a hook echo quickly and goes tornado warned. That, or we sit and watch mush all afternoon and drive back empty handed.

Will be shooting to be near the St. Louis area around 1 or 2.
