If you've got outdoor plans for St. Patrick's Day today, be sure to bundle up because it's going to be quite chilly! There is even a low chance for light snow overnight, but we don't expect significant impacts. Then, a rapid warmup carries us to the end of the week, with temperatures back into the 70s and even low 80s by Friday and Saturday.
Three tornadoes across southwest and south-central IL were surveyed today, with one more tornado still being reviewed in Montgomery County, IL. This map shows the completed tornadoes, please refer to the website in the graphic for more details. We expect our survey work to be completed tomorrow.
