Humidity streaming northward from the remnants of Rosa and the Gulf of Mexico will push into an area much below average temperatures. With a strong low and ample upper level energy, snowfall will begin to accumulate.
Snow will begin to develop in the Montana mountains this afternoon and push into North Dakota late tonight into Friday. The low will move into Canada and exit the region by Saturday, bringing an end to the slushy accumulations.
