825 AM MDT Thu Sep 21 2017

...COOL AND WET THROUGH FRIDAY...
...BREEZY CONDITIONS ACROSS THE BLM FRIDAY...

.DISCUSSION...
An upper low continues to spin over the region through Friday.
This brings rain and snow showers to the region with snow levels
around 5500 feet then increasing to 6000-6500 Friday. Winds can be
expected to increase across the BLM lands Friday afternoon as
the surface low drifts into Eastern Idaho. Drier conditions are
expected Saturday as an upper ridge moves into the Pacific
Northwest. A fast moving upper disturbance is now expected to drop
into the region Sunday with another brief round of precipitation.
