Very sharp cut off between heavy snow & nothing today! Dana IL got 12" of snow, while only 28mi away as crow flies, Ottawa's ground is bare! pic.twitter.com/8ng0pvpaRO— NWS Chicago (@NWSChicago) March 25, 2018
The heavy, wet snow has continued to result in difficult travel conditions across much of central Illinois this afternoon. Reduce speed and increase following distance when driving on snow or slush covered roads. pic.twitter.com/SqXuES45D1— NWS Chicago (@NWSChicago) March 24, 2018
Snow will gradually end this evening across the southwest. Warmer weather is then expected for the first part of next week, with periods of rain late Monday through Wednesday morning. pic.twitter.com/xtsT7SFAVb— NWS Chicago (@NWSChicago) March 24, 2018
Heavy, wet snow south and west this afternoon is expected to continue for several more hours. Visibility under one half mile and slushy conditions on roads have been observed with the heavier bursts of snow. pic.twitter.com/es9jbDWWrv— NWS Chicago (@NWSChicago) March 24, 2018
Conditions on the northern edge of the snow this morning vary considerably over a short distance. Here is a look at IDOT webcam images on I-39 and I-80 near La Salle around 10:30am. ~10mi separate the I-80 webcams, while ~20mi separate the I-39 webcams. pic.twitter.com/ppkIAStlng— NWS Chicago (@NWSChicago) March 24, 2018
Another round of heavy, very wet snow will continue to spread across southwest portions of our forecast area this morning. Expect slushy accumulations of up to 1 inch per hour into the afternoon. pic.twitter.com/pAyDxXZBAP— NWS Chicago (@NWSChicago) March 24, 2018
