The threat for severe weather in the area covered by severe thunderstorm watch number 363 (the one that covers northern Indiana) continues, according to a mesoscale discussion that the National Weather Service Storm Prediction Center issued at 10:20 p.m. EDT. The discussion indicates that a large hail threat might be developing over Illinois as storms regenerate there and then form a train toward the east, creating a heavy rain threat. The discussion indicates that a new watch might be needed over portions of Illinois and Indiana, as watch number 363 is set to expire at 11 p.m. EDT.
