Multiple snow chances exist this week. Light accum snow for later Tue night, possibly into early Wed a.m.. Multiple snow chances Thu-Sat. pic.twitter.com/VDctIzs9Do— NWS Chicago (@NWSChicago) February 5, 2018
The snowy pattern that arrived with February continues. After snow ends later this evening, more snow -- though mainly light -- is expected later Tuesday night through the pre-dawn hours on Wednesday. This could result in slowed travel for the Wednesday a.m. commute. #ilwx #inwx pic.twitter.com/pE8eVhCRnF— NWS Chicago (@NWSChicago) February 5, 2018
Areas of heavier snow developing this afternoon. Vis less than 1/2 mile and inch per hour rates likely in these areas. #ILWX #INWX pic.twitter.com/5qqDKd2tWA— NWS Chicago (@NWSChicago) February 5, 2018
Snow is quickly spreading across the area. Conditions will deteriorate shortly after the snow starts, with snow easily accumulating on roads & falling visibility. Leave yourself plenty of extra time to reach your destination during commute. Webcam is from #Rockford #ilwx #inwx pic.twitter.com/kjzQzep43N— NWS Chicago (@NWSChicago) February 5, 2018
Snowfall reports will be much appreciated through this evening. Here are the six basic steps for properly measuring snow. #ilwx #inwx pic.twitter.com/NUaYmSieT0— NWS Chicago (@NWSChicago) February 5, 2018
Don't let the sunny morning we had deceive you. Snow is moving into NW IL & spreading east quickly. It will begin in Rockford between 1-2 pm & in Chicago near or shortly after 3 pm. Plan ahead & allow much more extra travel time during the eve commute & be cautious. #ilwx #inwx pic.twitter.com/bhUYY9rZKC— NWS Chicago (@NWSChicago) February 5, 2018
Plan for MUCH longer travel times during PM commute today. Accumulating snow & very cold temps will make for a bad mix, as snow will easily stick on road surfaces. Details for commute time (~3-6pm CST) on graphic. Leave plenty of extra time to reach your destination! #ilwx #inwx pic.twitter.com/RASbSSYNmz— NWS Chicago (@NWSChicago) February 5, 2018
The coldest morning since mid January. Bundle up if spending prolonged time outdoors! Snow will arrive this afternoon. #ilwx #inwx pic.twitter.com/6J2GB56nxs— NWS Chicago (@NWSChicago) February 5, 2018
Snow will overspread nrn IL & NW IN early to mid afternoon and continue through late eve. Snow will be moderate to heavy at times with half pic.twitter.com/vEVLlEUf0D— NWS Chicago (@NWSChicago) February 5, 2018
