ROMEOVILLE — The heat is on across Illinois.
The National Weather Service says it will feel like 105 degrees across parts of the state on Thursday as a heat wave continues to bake Illinois.
The forecast calls for highs in the low-to-mid 90s with high humidity and sunshine, which will make it feel like it's between 100 and 105 degrees. Friday should be even worse. That's when the heat index climbs to 108 degrees.
Federal weather officials say the steamy weather could cause rolling blackouts and buckled pavement.
Meanwhile, public health officials are opening cooling centers and warning people to drink plenty of fluids, check on neighbors and take precautions if they're outside.
A heat advisory will remain in effect through Friday evening before cooler weather arrives for the weekend.
