January continued its cold pattern this week. Average temperatures ranged from the mid teens to the high 20s across the state, between 4 and 12 degrees below normal. Some of the more impressive nighttime low temperatures this week included -7 degrees in Aurora and -6 degrees in Champaign. The first half of the month has at least felt quite cold, and has been colder than normal; however, this month so far is only among the top 40 to 50 coldest on record in Illinois.…

The first full week of the year was more winter-like than pretty much anything we had in 2024. Average temperatures this week ranged from the low teens in northern Illinois to the mid-20s in southern Illinois, between 3 and 6 degrees below normal. High temperatures regularly struggled to make it above freezing while low temperatures dipped near to below zero on a few nights. Some of the more impressive nighttime low temperatures included -2 degrees in Champaign and -1 in Lincoln.…

Happy new year! We’ll start 2025 by looking back at 2024 and then looking ahead to some significant weather this upcoming week.

What we do know is that 2024 was the warmest year on record in both Chicago and Peoria, and a top 5 warmest in most cities around the state.…

This year has been very warm across Illinois, to the tune of 3 to 4 degrees above normal. Through the middle of December, 2024 has been the warmest year on record in Chicago, Peoria, and Carbondale, and a top 5 warmest year on record virtually everywhere else across the state. Ironically, it was July – the climatologically warmest month of the year – that had statewide average temperatures farthest below normal. The mid-summer cool down was welcome following a very warm and dry start to the growing season. …

The first week of climatological winter brought at long last a prolonged taste of winter to Illinois. Average temperatures this week ranged from the low 20s in northern Illinois to the low 30s in southern Illinois, between 8 and 14 degrees below normal. Nighttime low temperatures this week regularly dipped into the teens and single digits, including 8 degrees in Springfield and 9 degrees in Kankakee.
