KEY MESSAGES

- Scattered light snow and patchy freezing drizzle will remain possible late this afternoon into this evening. Only limited travel impacts are anticipated, but there could be a few slick spots wherever wintry precip becomes focused. Drive with caution, especially during the late afternoon and evening commute.

- The coldest air of the season so far will arrive tonight and last through Friday morning. Take immediate steps to protect people, pets, and pipes from the cold.

LONG TERM

(Friday through Next Wednesday) Issued at 235 PM CST Wed Dec 3 2025

Dry weather is expected to continue Friday through Saturday, followed by a clipper system Sat night into Sun. Temps will be cold enough with this system that p-type will be all snow. After another dry period Sun night into Mon, two more clipper systems will drop across northern and northeast IL Mon night through Wed. P-type for the first of these two should be all rain. However, warmer air will advect northward into the area ahead of the second one, making the p-type forecast for this one tricky. This one will need to be monitored as it gets closer.

Temps will remain below normal most of the extended period, but a warming trend is favored toward the middle of next week.
