UPDATE: Jefferson High School students will have class Tuesday. The school was closed on Monday because of a power outage. ComEd says an underground power line broke and needed to be repaired.
All activities and practices scheduled for Monday at Jefferson have been cancelled as well.
A Com-Ed spokesperson says there was a break in one of the underground cables. Crews are still trying to figure out what's to blame. They hope to have power back on by 6:30 tonight. We're told no other buildings in the area are affected.
