Check out the full report here.
Organized t-storms are quickly moving into northwest Illinois with a possible line of storms expected to move through northeast Illinois as the morning progresses.
The time frame to be concerned is between 8 a.m. and 11 a.m. Monday. Some storms have the potential of producing strong winds gusts, hail and heavy downpours along with some cloud to ground lightning.
Ryan’s Advice: Have those weather radios handy! These storms are moving quickly to the east and may catch people off guard. Some warnings are also possible as the t-storm cluster moves through, so stay away from windows. I would be most concerned about the potential of damaging winds for some locations as the line approaches from the west.
