⚠ Late-season cold snaps can push overnight lows near or below freezing in early May. They occasionally bring wet snow flurries that melt by midday. Early morning trail surfaces become slippery. Road conditions turn temporarily poor on mountain passes south of town.
⚠ Afternoon thunderstorms build fast over the mountains south and west of Billings. They arrive with little warning. These storms bring hail, lightning, and wind gusts strong enough to turn exposed Rimrocks trails dangerous. Watch the sky. If cumulonimbus towers rise to the southwest, descend from high ground within 15-20 minutes. Don't wait.
⚠ Wind dominates the high plains here. It blows harder than forecasts predict. Sustained winds of 30-40 km/h (19-25 mph) hit often in May. Plan for this. Exposed trails and river activities suffer most. Wind chill cuts deep. Pack layers. Check conditions twice.
