Wider weather episode

On the morning of May 24th a low pressure system was located over the eastern Dakotas, with Illinois positioned in the warm sector. Over the course of the day, several rounds of thunderstorms occurred. First, a squall line tracked across Iowa and reached Illinois by the morning. The most intense part of this squall line tracked north of central Illinois, but the system did produce one instance of wind damage in Stark County. There was a lull in severe weather during the mid-to-late morning, but around midday the lingering storms began to strengthen, while new clusters of storms developed along the associated outflow boundary. These storms continued throughout the afternoon. A cold front moved into the area during the evening, resulting in additional scattered storm development, however, all of the storms weakened into the late evening as daytime heating was lost. Collectively, the thunderstorms on May 24th produced scattered wind damage, hail, and flash flooding across central Illinois.
