DISCUSSION

KEY MESSAGES:

- Alternating between cool/showery and mostly dry with an active weather pattern this week

- Warm and dry likely early next week

A few showers will be possible in northwest Montana today.
Elsewhere cooler than normal temperatures with light breezes will be the forecast.

Another disturbance will impact the Northern Rockies on Thursday, once again bringing widespread showers, with isolated thunderstorms mainly south of I-90. Snow levels during this event will range between 6,500 and 8,000 feet. A secondary disturbance is expected to move through the region from Friday into Saturday, keeping showers lingering over the Northern Rockies.

Nearly all long-range ensemble members are now in agreement that a ridge of high pressure will build over the Northern Rockies as early as Sunday and remain in place through the middle of next week. This will lead to a warming and drying trend, with afternoon temperatures ranging 10 to 15 degrees above normal by Sunday or Monday.
