Snow Day Predictor for Juneau, AK

Juneau is a smaller community of about 31,555 people that sits in the northern tier of the country, near 58.3°N in Alaska. A winter here typically brings anywhere from 40 to well over 100 inches depending on the community. Winters are long and cold, and schools are equipped for it. Because the town falls in the Alaska climate region, our model's closure threshold for Juneau is held to a high bar, because districts here are equipped for heavy winter weather and rarely cancel for routine snow.

The percentage at the top of this page isn't a static guess — it's rebuilt each night from Juneau's own Open-Meteo forecast. The model reads seven signals from the overnight-into-morning window: total snowfall, whether any of it is timed for the 2–6 a.m. commute, freezing rain or sleet, the coldest air temperature, the wind chill, the peak wind, and how much snow is already on the ground. Communities are built for snow; extreme cold, ice fog, and blizzard conditions matter more than routine accumulation. Wind chill and visibility, not inches, usually drive a late start.

Because a 2-hour delay clears a lower bar than an outright cancellation, you'll often see delay odds for Juneau even when the closure odds stay modest — that gap is the model flagging a borderline morning. The estimate shifts as the forecast firms up overnight, so it's worth re-checking Juneau's odds the evening before school. Treat it as a well-informed second opinion for planning, never as an official Alaska closing announcement.
