Upper-level divergence from a jet streak and frontogenesis along the US/CANADA border are causing precipitation to fall over the Pacific Northwest. A surface low is beginning to form over north-central MT at this time. This quick moving disturbance will be progressing southeast towards the Dakotas and Central Plains by tomorrow afternoon.
