How to read your result in Idaho

• 40–60%: borderline—watch timing (overnight vs. daytime) and ice risk near freezing.
• 60–80%: prepare for disruptions; monitor district alerts.
• 80%+: high chance of delays or closures, especially with early‑morning snow.

Weather can vary within the state—elevation, proximity to lakes or the coast, and local plow resources all matter. Always confirm with your school district.
