If you’ve spent more than five minutes in Ottawa County, you know the deal. You look out the window in the morning and it's sunny. By the time you’ve finished your coffee at a local spot near Grand Valley State University, you’re looking at a whiteout.
Allendale is basically the front lines for Lake Michigan’s mood swings.
Right now, we are sitting at a crisp 24°F. Honestly, it feels way colder—more like 14°F—thanks to that 8 mph northwest wind cutting across the flat farmland. It’s cloudy, which is pretty much the default setting for January around here. In fact, historically, Allendale is overcast about 70% of the time this month. If you’re looking for Vitamin D, you’re in the wrong zip code today.

The Week Ahead: Arctic Air is Moving In
If you think the low 30s are bad, brace yourself for Monday.
We are looking at a serious temperature cliff. Sunday stays around 19°F, but by Monday, January 19, the high is only 8°F. Yes, a single digit. The low that night? 5°F.
With 21 mph west winds forecasted for Monday, the wind chill is going to be brutal. This is that "stay inside and order pizza" kind of weather.
Quick Glance at the Numbers:
- Saturday (Jan 17): High 25°F, Low 20°F. More snow showers (35% chance).
- Sunday (Jan 18): High 19°F, Low 7°F. Consistent snow showers.
- Monday (Jan 19): High 8°F, Low 5°F. Windy and dangerous cold.
- Tuesday (Jan 20): High 23°F, Low 7°F. Slightly better, but still snowing.
Why Does It Snow So Much Here?
It’s the lake. It always comes back to the lake.
Even when the rest of Michigan is dry, Allendale can get hammered. This is because we are perfectly positioned downwind of Lake Michigan. Cold air picks up moisture from the relatively warmer water, and as soon as it hits the land, it drops.

On average, Allendale sees about 21.5 inches of snow in January alone. Compare that to the rest of the year, and it’s clearly the "peak" of our winter misery.
Actually, the humidity is staying high too—around 68% to 87% over the next few days. That’s why the cold feels so "wet" and bone-chilling compared to a dry cold out west.
Survival Tips for the Allendale Winter
Most people get the basics wrong. They think one big coat is enough.
Expert locals know it’s about the layers. You need a base that wicks moisture, a middle for insulation, and a shell to block that 21 mph wind we’re expecting on Monday.
Also, watch out for the "flash freeze" situations. When the temp swings from 32°F on Friday down to 19°F on Sunday, any slush on the roads is going to turn into a skating rink.
Next Steps for You:
- Check your tires: If they’re balding, the southwest Michigan slush will find you.
- Stock the pantry: With those single-digit highs coming Monday, you won't want to leave the house.
- Watch the wind: Monday’s 21 mph gusts are the real danger; limit skin exposure.
