Idaho, winter is hitting us hard this weekend as a blast of Arctic air moves in, bringing extreme cold and dangerously low wind chills. The National Weather Service has issued warnings, and now’s the time to prepare—temperatures like these aren’t just uncomfortable, they’re downright dangerous.

Boise:
In Boise, we’ll see some sunshine today, but don’t let it fool you—it’s going to be cold. Highs will only reach 36°F (2°C), and tonight it’ll drop to 19°F (-7°C). The good news? The coming week will stay mostly sunny, but with highs in the mid-30s°F and lows in the teens, it’s still going to feel icy.
Idaho Falls:
Things are much colder in Idaho Falls. If you stepped outside this morning, you probably felt that bone-chilling -2°F (-19°C). It won’t warm up much, with a high of just 17°F (-8°C) and a low tonight of 3°F (-16°C). Adding to the challenge, an Extreme Cold Watch is in effect from late Sunday night through Monday morning. Wind chills could drop as low as -20°F to -30°F (-29°C to -34°C), which means frostbite can set in on exposed skin in just 10 minutes.
Coeur d’Alene:
In Coeur d’Alene, temperatures are a bit more manageable but still chilly. Today’s high will hit around 32°F (0°C), with lows dropping to 19°F (-7°C). The week ahead will bring a mix of sun and clouds, with highs in the low-to-mid 30s°F and lows in the teens.
What You Can Do to Stay Safe
When it gets this cold, staying safe and warm should be your top priority. Here are some simple steps to help you get through it:
- Dress in layers and cover up as much as possible. Hats, gloves, and scarves are your best friends right now. If you’re going outside, make sure no skin is exposed—frostbite can happen fast.
- Limit your time outdoors. These temperatures aren’t just uncomfortable—they’re dangerous. If you don’t have to go outside, don’t.
- Bring pets indoors. If you’re cold, they’re cold too. Make sure they have a warm and safe place to stay.
- Check on neighbors, family, and friends, especially anyone who might need extra help staying warm. A quick call or visit can make a big difference.
- If you’re traveling, make sure you have an emergency kit in your car. Pack blankets, snacks, water, and a flashlight in case you get stuck.
