According to CBS 2 meteorologist Ed Curran, some areas may also experience heavy downpours. The biggest concern, however, is for Saturday afternoon and early evening as northern Illinois has the potential for significant severe weather.

Far northeast Illinois is at a slight risk. Farther south, the risk elevates to the east. To the southwest, including La Salle County the risk is moderate. That’s level four out of five levels.

 

The possibility of large, long-track tornadoes is highest to the southwest. These storms not only have the potential to be very dangerous but will also be very fast-moving.

It’s not out of the question that the threat level could be raised to HIGH on Saturday, given the dynamics in place and the high population density of the region.
