This article answers the most searched questions people are asking right now about the Madison WI extreme cold warning, using verified data from Channel 3000 and other regional weather reports.
What is the Dangerous Cold Alert Day in Wisconsin?
A Dangerous Cold Alert Day means conditions are cold enough to cause frostbite and hypothermia very quickly.
In this case, Madison weather today includes:
- Actual temperatures falling into the negative teens to -20s
- Wind chills plunging to -40 to -45 degrees
- Extreme Cold Warning issued statewide from 12am to 1pm Friday
- Cold Weather Advisory from Friday afternoon through noon Saturday
These alerts are issued only when cold reaches levels that pose a serious health risk.
Why is Madison WI experiencing extreme cold right now?
This extreme cold is caused by a powerful arctic air mass moving south from Canada.
According to First Warn Weather:
- Strong northwest winds of 10–20 mph with gusts up to 30 mph
- Clear to partly cloudy skies allowing heat to escape overnight
- Very dry air enhancing wind chill impact
This combination is why Madison Wisconsin weather feels much colder than the thermometer shows.
How cold will it get in Madison Wisconsin?
Here is what the verified forecast shows for Madison WI:
| Weather Factor | Expected Conditions |

| Overnight Lows | Negative teens to -20s |
| Wind Chill (Worst) | -40 to -45 |
| Daytime Highs (Weekend) | Slightly above zero |
| Morning Wind Chills | -15 to -30 |
| Snowfall | Little to none |
Even when temperatures rise slightly during the afternoon, wind chills remain dangerous.
How fast can frostbite happen in this weather?

Exposed skin like:
- Fingers
- Ears

are at the highest risk. This is why outdoor exposure should be kept to an absolute minimum.
Is there snow expected during this extreme cold alert?
No significant snow is expected.
First Warn Weather confirms:
- Little to no falling snow through the weekend
- Cold is the primary danger, not visibility or accumulation
This makes the situation deceptive because roads may look clear, but conditions are still dangerous due to wind chill.
How long will the Madison weather alert last?
The Alert Day continues through Sunday morning.
Even after the arctic air begins to move east:
- Highs next week stay in the teens
- Lows hover near zero
- Morning wind chills remain below zero most days
This means Wisconsin does not get a quick warm up.
What should Madison residents do during extreme cold?
The guidance from weather experts is clear.
Personal safety steps:
- Avoid unnecessary outdoor activities
- Wear multiple insulated layers
- Cover all exposed skin
- Limit time outside to minutes, not hours
Home safety:

According to First Warn Weather:
- Pets should not be left outside

- Short, supervised bathroom breaks only
If it feels too cold for you, it is too cold for your pet.

- Extreme Cold Warning
- Dangerous Cold Alert Day
- High risk of frostbite and hypothermia
Meteorologists stress that this is one of the colder stretches of January 2026.
