Forecast Snowfall Ranges - This Weekend

🌬️ Strong and potentially damaging northeast winds are expected to impact Northwest Montana Sunday night into Monday. Key Concerns: Wind Gusts: Gusts of 40 to 50 mph are possible, especially for the eastern part of Flathead Valley, southeast portions of Flathead Lake/ Finley Point, and surrounding mountain areas. Unique Impacts: Heavy, wet snow above 3000 feet on Sunday will still be clinging to trees. This extra weight, combined with wet, unfrozen ground and strong winds from a seasonally abnormal direction, significantly increases the likelihood of falling trees and branches. Primary Threats: 🌲 Falling trees and branches. ⚡ Potential for power outages. 🌊 Damage to docks on Flathead Lake due to strong winds. Please take time this weekend to secure any loose outdoor items. Stay aware of your surroundings if you are outdoors on Sunday night and Monday.
