Another powerful storm system will bring a risk for severe weather to the region this afternoon and tonight in two rounds. The first round is expected to occur this afternoon and evening, with strong to severe thunderstorms along and ahead of a dryline to our west. Any storms that develop will have the potential to become severe quickly, bringing a risk for very large hail (perhaps larger than baseballs), damaging wind gusts, and a tornado or two. These storms will track towards the northeast. The second round will occur overnight and into Wednesday morning as a line of storms blasts from west to east across the entire region. The main hazards with this second round of storms will be damaging wind gusts, hail, and perhaps an isolated tornado. There will also be a risk for localized instances of flash flooding due to earlier heavy rainfall.
