Let It Snow: 2025-2026 Snow Report

Snowfall Conditions, Trends, and Expectations for this season

As most midwesterners know, our weather varies greatly year to year - even day to day. We are no stranger to dramatic 50+ degree swings in temperature, and it's not all that uncommon to wear an insulated coat one day and sandals the next. Similarly, snow amounts vary annually, seemingly with no rhyme or reason. This season we have already experienced more snowfall than previous years, but are still far behind regional records.


Fortunately for researchers, the Chicago-Rockford International Airport is home to a NOAA National Weather Service station that measures and shares climatological data like precipitation, temperature, wind speed, among many other variables. Today, we are focusing on precipitation, namely: snow.

Patterns and trends

First, let’s bring it back to Earth Science class to talk about the La Nina and El Nino weather patterns. You can read all about it in a previous blog here: https://www.seversondells.com/blog/laninawinter. La Nina is the pattern that we are currently experiencing, and can explain the damp winter we have had thus far. Contrarily, El Nino is the weather pattern that causes more mild, dryer winters.


Before talking numbers, it's important to preface that minute, hyperlocal changes in temperature can mean the difference between no snow or lots of it in a specific area, and conditions may differ just a few streets away. Snow can be difficult to predict. Climatologists and Meteorologists use different models to attempt predicting the future, but these are just models.

The cold, hard data

For the purposes of this blog, I looked at snow accumulation data from November through March, as these are the most consistent months we receive snowfall.

The AccuWeather exclusive forecast predicts 32-38” of snowfall for this season, which is in line with the 30 year average (38.4” between 1991-2020), but is significantly higher than last year’s cumulative snowfall totalling only 17.6”. As of the first week of December, Rockford had already recorded as much snow as the entire previous winter at 17.1”. In fact, this has been the snowiest start to winter since recordkeeping began 120 years ago around 1905. While there is no long-term trend in snowfall in Illinois, the last decade has shown more variability, accounting for the big changes we see year to year.


While researching, I noticed that January and February tend to be peak snowfall months, so don’t be fooled by the lack of snow right now because the worst may be yet to come. 


Other (not-so-technical) Prediction Methods

For as long as humans have existed, we have searched and invented ways to measure, tell, and document time, including anticipating the future. Natural phenomena can provide an ecological calendar for our reference.


One common anecdote of winter severity involves a frequent backyard visitor: the wooly bear caterpillar. Folklore suggests that the wider the black bands on a wooly bear caterpillar, the more bitter the upcoming winter will be. Contrarily, a wider brown band indicates a milder winter ahead. Some people also note the thickness of the wooly bear’s ‘coat’ as well as the direction of travel (i.e. headed south to escape the winter!).

Another famous animal we turn to for wintertime answers is Punxsutawney Phil on February 2nd for Groundhog Day, where the presence of his shadow predicts how many more weeks of cold winter are yet to come. 

In more fun and potentially predictive animal news, there is speculation in the bird world that this may be an irruption year for Arctic birds like the snowy owl. An irruption year (different than volcanic eruptions) describes an ecological event where suboptimal conditions in the arctic circle drive wildlife populations further south in search of food. Humans sometimes use the presence of snowy owls as a cue for winter severity: Colder conditions in the arctic translate to colder conditions elsewhere as well. You may have already heard about a pair of snowy owls hanging out around Montrose Point Bird Sanctuary on the Chicago lakefront back in November. Other notable occurrences in recent years include 2011-2012, 2013-2014, 2018-2019, and 2021, which typically coincided with other high snowfall years.


Regardless of what the future weather may look like, winter provides great opportunities for us to spend time outdoors. Whether you build a snowman, make ephemeral art in your backyard, watch birds, volunteer at a conservation workday, or just take a walk in your neighborhood - the most important thing is getting outside! And you’re in luck as we have plenty of programming this winter to enjoy. View all of our programs here: https://www.seversondells.org/events

Meet Holly: Wild Roots Community Engagement Manager

By Holly Hansen • July 9, 2026
While many of you may already know me, allow me to introduce myself! I’m Holly and I’m the new community engagement manager here at Wild Roots Nature Center . While I am new to this role, I am not new to Wild Roots. I got my start at Wild Roots way back in 2019 as an environmental education AmeriCorps Volunteer. During my time, I was able to help connect people to nature and foster stewardship of our lands at all age levels. Even when COVID-19 hit, that didn’t stop us from planning for the future and coming up with ideas for how to engage people in our natural world. From there, I completed two more terms of service with AmeriCorps, one in Florida and one back here at Wild Roots with 815 Outside. (You’ll start to notice a pattern here.) As I finished my undergraduate degree in environmental studies and my master’s degree in higher education and student affairs, I remained a volunteer with Wild Roots, joining in on the fun of Science Saturdays, signature events like Luminaria, and canoe convoys. I simply never left this community. My most recent role as assistant director of campus sustainability at Northern Illinois University has prepared me for my return to Wild Roots. I’ve learned so much over the years about connecting with people of all different backgrounds, bridging the gap between nature and community. I look forward to continuing these conversations as the community engagement manager at Wild Roots Nature Center! Other fun facts: When I’m not in nature, you can find me among a circle of friends, crafting and laughing, making stained glass art, and immersing myself in a good book or tv show. I’m always happy to be a listening ear and I am fiercely loyal. Plus, I’ll never say no to a new adventure!

Meet Brandy: Wild Roots Finance and Administrative Coordinator

By Brandy Korth • July 2, 2026
If there’s one thing you should know about me, it’s that I genuinely love people, organized chaos and finding joy in the little things. So, when the opportunity came to join the team at Wild Roots, it felt like everything came together in the best way. Professionally, I’ve spent more years than I’d like to admit in finance, bookkeeping and office management. I actually enjoy spreadsheets, balancing budgets, and making sure all of the behind-the-scenes pieces fit together (yes…I’m one of those people!). But my energetic and bubbly personality doesn’t always fit the type for an accounting aficionado. Before building my career in finance, I earned a degree in Elementary Education. Looking back, it makes perfect sense because teaching and finance have one thing in common – you need patience, flexibility, quick on your feet, and a good sense of humor! I absolutely love the fact that Wild Roots is so committed to outdoor education, and it is one of the biggest reasons I wanted to root myself here as well. Perfect blend of both of my worlds. Outside of work, I’m a proud mom to three wonderful (and very energetic!) boys. They keep me on my toes, whether we’re at a ball field, exploring a new park, or simply enjoying time together. Being their mom has taught me that the best adventures don’t have to be big – they’re usually found in the simple moments, especially when you’re outside exploring together! That’s one of the reasons Wild Roots already feels like the perfect place. I believe nature has an incredible way of bringing people together, slowing us down, and reminding us to appreciate the world around us. Knowing that I get to support an organization that helps families, students and our community experience that every day is something I am truly excited about.  I’m incredibly grateful to be here and can’t wait to be part of everything that makes this place so special. Here’s to new beginnings, new connections, and plenty of time spent enjoying the beauty of nature together!
