The little engine that couldn't

After such great severe weather hype, things never materialized yesterday. One of the things that set us apart yesterday was the cap that was in place. Oftentimes we talk about the cap in the summertime. As temperatures at the surface warmed into the 80s yesterday afternoon the atmosphere continued to warm as you went up 5,000-15,000 feet. In order to get efficient lift (needed for thunderstorm development) we need falling temperatures with height. This allows air parcels to rise forming clouds and rain.

Storms did fire early this morning, but most of the activity was located behind the front (and behind the juiciest airmass). Severe weather will be limited to places like Toledo, Columbus, Indianapolis, and Louisville today. -ERIC
