| Episode Narrative | Following a week of record highs, a late winter severe weather outbreak brought widespread severe thunderstorms to Iowa, Illinois, and northeast Missouri. Supercell thunderstorms produced numerous reports of large hail and a few tornadoes. The tornadoes were the first ever recorded in the month of February, across eastern Iowa and northwest Illinois. Additionally, some damaging winds occurred after dark, when the storms formed into a line as they moved through Illinois. This outbreak of severe weather also included many locations in the southern half of Illinois, and Missouri. |
| Event Narrative | National Weather Service storm survey showed damage consisting of snapped pine trees, damaged farm out buildings, and an un-roofed attached garage and home along the path. A second home also sustained damage to its roof. The estimated peak wind was 100 mph. |
