Up to 30 cm of Snow Confirmed: See Which States Will Be Hit and When It Starts

There’s a chill in the air, and it’s not just the drop in temperatures. Across several parts of the United States, meteorologists are sounding the alarm about an incoming snowstorm that could disrupt travel, daily life, and holiday plans. With forecasts now confirming snowfall of up to **30 centimeters (nearly one foot)** in certain regions, local officials and residents alike are preparing for what is shaping up to be a significant early-winter blast.

While some states are familiar with seasonal flurries and icy conditions, the level of snow predicted in this upcoming system is catching even seasoned snow-watchers off guard. The snowstorm is not only expected to be heavy but to move quickly—dropping large amounts within a short period—posing additional challenges for travel and public safety resources. If you’re living in or planning to travel through any of these identified states, knowing the timing and severity could make all the difference.

With snowfall ranging from light accumulation to over **30 centimeters in some regions**, the coming days could see school closures, power outages, and severe traffic disruptions. The **Weather Prediction Center** and local meteorological offices are issuing warnings designed to give people enough time to prepare. Below, we break down which states are expected to be hit the hardest, when the storm is likely to arrive, the areas of highest concern, and how you can get ready.

Which states are in the storm’s direct path

According to official forecasts, the upcoming snowstorm is expected to sweep across at least **12 U.S. states**, starting from the Midwest and moving towards the Northeast. Among the states facing the most significant impact are:

  • New York – Particularly upstate and central regions
  • Pennsylvania – Including the state’s western corridor
  • Ohio – Heavy snow in central and northern zones
  • Michigan – Lake effect and direct accumulation areas
  • Illinois – Especially Chicago metro area
  • Indiana – Northern and central regions
  • Wisconsin – Continued cold patterns fueling snow
  • Vermont & New Hampshire – Significant overnight snow forecasted
  • Massachusetts & Maine – Possible coastal snow complications

When to expect the most intense snowfalls

The stormfront is currently forecasted to begin affecting states late Wednesday, with a sharp uptick in snowfall rates overnight. The most intense period is expected during **Thursday morning through Thursday evening.** This will overlap with morning and evening commutes, compounding hazards for roads and public transit users.

This system is expected to move rapidly, which means that although the storm will not linger for days on end, it will deliver intense snowfall within a confined window of time. The **heaviest snowfalls**, potentially reaching near 30 centimeters (or one foot), are expected primarily in **upstate New York, western Pennsylvania, and parts of northern Ohio**.

How local governments and agencies are prepping

In advance of the storm, municipal and state-level response teams have been activated. Public works employees are working extended shifts to get snow plows, salt trucks, and emergency vehicles prepped and ready. Emergency alerts are also being sent out to residents in vulnerable zones, advising them to avoid unnecessary travel and stock essential supplies.

Potential disruptions to travel, school, and more

The dual concern of **commute-time snowfall** and poorly treated roads could result in severe delays and possibly **road closures** across interstates and rural routes. Airports in affected regions, particularly O’Hare (Chicago), LaGuardia (NYC), and Logan (Boston), may see **multiple cancellations and delays** during the storm’s peak. Parents should also be aware that school districts across multiple states are considering closures or remote options.

“If this forecast holds, we’re likely looking at a snow day for most students in our district.”

Who could be most affected and why

While most residents of these states are familiar with wintry weather, this particular storm comes early in the season and could surprise those lulled into a false sense of normalcy by recent mild temperatures.

In addition to urban areas with heavy traffic, **rural and mountainous regions**—where emergency services take longer to deploy—face heightened risk. The elderly, individuals with mobility issues, and those without backup heat or electric sources should take extra precautions.

How residents can prepare effectively

Experts recommend a short checklist of preparations to stay safe and reduce inconvenience:

  • Stock food and water for 2–3 days
  • Charge all devices in advance
  • Top off gas tanks in vehicles
  • Keep a winter emergency kit in your car
  • Have alternative heating options if possible
  • Stay updated via local emergency alerts

If you are planning any travel over the next 72 hours in the impacted zones, consider delaying non-essential trips. Airlines and rail services are waiving change fees in some cases due to the expected severity of the weather.

What to watch for after the snowstorm passes

While accumulation is the initial concern, the aftermath of the storm could bring **freezing rain, black ice, and dangerously low temperatures.** These factors may extend the impact well into the weekend. Residents should watch for overnight refreezing on roadways and sidewalks. Additionally, melting snow may contribute to **minor flooding** in low-lying areas, especially if followed by rain.
