ESFTFX Warming temperatures through next week will lead to changes in river ice conditions and an increased risk of river ice breakup and the potential for ice jams. Lower elevation snowmelt and still frozen ground could also lead to some increased runoff into creeks and rivers, adding to the potential for river ice breakup. Ice jams are unpredictable and flooding can rapidly occur, so those with interests along waterways should monitor water levels over the coming week and take action should flooding occur. Additionally, frozen ground after a prolonged cold period and melting snow may result in standing water in areas of poor drainage. This could create difficult access to fields and impact some rural roads. As temperatures warm up more early next week and the ground begins to thaw, muddy conditions may create additional impacts. The greatest risk for overland impacts from snowmelt look to be from eastern portions of Teton and Pondera counties across portions of Cascade and Chouteau counties and most lower elevation areas in Judith Basin and Fergus counties, where water equivalent in the lower elevation snowpack ranges from around 1.0" to as much as 3.0 to 4.0" in portions of Fergus county. These areas are also most susceptible to overnight temperatures remaining near or above freezing tonight through early next week. Across Southwestern Montana, there is significant water content in the snowpack in the Gallatin valley, however melting will likely be slower with overnight temperatures continuing to fall below freezing. Stay tuned to the forecast for the latest temperature trends, along with any warnings or advisories that may be issued. Please report any flooding to local law enforcement. Do not drive over flooded roadways as the roadbed may be washed out. Turn Around, Don't Drown.
