There's a robust MCS ongoing over here this morning. It's the classic back-building, storms-on-the-back-edge scenario. I've been on the front edge, so it's just a solid slow-soaker here. An area just southwest of Cedar Rapids has received 2-3 inches of rain this morning, with more heavy rain popping over them. It's going to take a while for this stuff to dissipate, so afternoon instability is iffy.
