Forecast Summary
- A trough digs down across the Rockies on Saturday, bringing widespread rain/snow, and dropping temperatures down well below normal.
- Several inches of snow are expected this weekend across the higher peaks of ID/MT/WY.
- A second storm moves in immediately behind the first, allowing snow to continue and keeping temperatures well below normal through the first half of next week.
A pair of low pressure systems are currently combining over the Pacific Northwest, forming a trough that will drop down over the Four Corners area by Sunday. The leading edge of this trough will act as a cold front, which is expected to move over Eastern Idaho/Western Montana Saturday afternoon, and Northwest Wyoming Saturday night.
Rain and snow showers will begin falling several hours before the arrival of the cold front. Snow levels will start out around 6,500 feet, gradually falling to as low as 3-4,000 feet overnight.
This first storm is expected to produce a few inches of snow across terrain above 8,000 feet or so, with around 6-10 inches expected on the higher peaks, before it moves off Sunday night.
