A warm, dry stretch of weather across the Northern Rockies comes to an abrupt end later this week as a storm drops down from Canada, bringing much colder temperatures and widespread snow. While a typical storm track moves over the Rockies from the west, this storm will move almost perfectly north-to-south over Montana and Wyoming. Therefore, snow will mostly miss some areas that usually get hit hardest, like Sun Valley and Jackson Hole.
This week starts with very warm temperatures across the Northern Rockies, with most areas between 10-20°F warmer than usual on Tuesday. However, a strong cold front sweeps across the region on Wednesday and Wednesday night, dropping temperatures by as much as 40°F.
That cold front will also produce a large swath of rain and snow, which changes to snow for almost all areas by late Thursday when the coldest air settles in. As is usually the case, the heaviest precipitation is expected to fall along the front, with heavy snow expected, at least for a brief period, across some of the highest peaks of Montana and Wyoming on Wednesday/Wednesday night. Less intense but more widespread, snow then continues through Thursday and to a lesser degree Friday. Snow tapers off Friday night as this storm moves off to the east.
Resort Forecast Totals
- Bridger Bowl (MT) – 5″-10″
- Big Sky (MT) – 4″-8″
- Red Lodge (MT) – 8″-16″
- Jackson Hole (WY) – 3″-8″
- Antelope Butte (WY) – 6″-12″
The rest of April is expected to remain active, with several weaker storms lining up to produce more spring snow in the Rockies. This storm looks like the coldest, so expect milder temperatures for the second half of the month.
