The National Weather Service says they are monitoring a “strong storm system” moving into the northern Illinois area later this week that could bring snow.
The National Weather Service (NWS) said Tuesday that the system will move into the region Thursday night and Friday.
The potential for winter weather impacts “is increasing,” particularly across northern Illinois, the weather service said.
Uncertainties remain in the storm track.
A farther north track would bring mainly rain to the region along with an increased threat of thunderstorms, heavy rainfall and flooding.
A farther south track would shift the axis of impactful snow more into Indiana, the NWS said.
Temperatures will be in the 30s, leading to a wetter and heavier type of snow where it is cold enough to accumulate.
Current radar models show the Chicago area is projected to receive heavy snowfall.
Those predictions could change as the storm system moves into the area.
Temperatures are expected to temporarily turn warmer for Wednesday but a cold front will pass through late Wednesday evening cooling temperatures for the second half of the week, the NWS said.
