April 19th, 2011:

A widespread severe weather outbreak affected numerous states from Texas to Pennsylvania. The SPC received over 1000 storm reports, over 900 of which were for wind and hail. 80 tornadoes were confirmed, including an EF3 near Girard, Illinois.

Morning 500 mb analyses from my top 4 chase days:
6/16/14, Pilger, NE
5/24/16, Dodge City, KS
6/16/25, Wellfleet, NE
5/28/13, Bennington, KS, 1.0

These patterns all support slow moving storms along mesoscale boundaries under modest 500 mb flow. Big negatively tilted troughs are overrated.

Radar loop of the tornado-warned line of storms last night. A mesovortex developed within the line west of Champaign-Urbana, prompting the tornado warning. This vortex dissipated as it approached town, while a weaker circulation developed to its north, tracking near campus.

Analysis by Matthew Cappucci: I’ve chased a lot of tornadoes in my day. I’ve intercepted 60, lost nine windshields to giant hail and driven close to 100,000 miles.

Here’s a breakdown of some of the most impressive and memorable tornadoes I’ve seen:

The ultrawide view of a developing tornado shows its foundations in the entire supercell. That's way more fun than zooming in on ground swirls, no?

ILX issues Summary Local Storm Report, 68 out of 68 reports were previously sent and not repeated here. Link

Numerous reports around Bloomington-Normal of trees and power poles snapped. The power was out here from 9 p.m. to around 4 a.m. after a report of a 65 mph wind gust at the airport. Another report had a gust of 85 mph.

Photos of Wednesday's spectacular supercell in western Pennsylvania, a storm straight from the plains. One of the most amazing things I've ever seen, easily the most impressive supercell I've captured outside of Tornado Alley. I'll be thinking about this for a long time

It's spring in the Midwest. Fortunately, the circulation weakened as it approached Champaign-Urbana.

I live in the same area. Fortunately, the circulation weakened as it approached Champaign-Urbana. The line of storms was forecast to weaken near I-57

Those storms are toast. QLCS after dark it is

It's going to have to be around then, because LL shear is bad until the LLJ ramps up

That is a verified target
