KEY MESSAGES

- Warm and dry conditions persist through Friday.

- Temperatures will gradually trend cooler through the weekend into early next week.

- A more unsettled pattern is expected next week, although a lot of uncertainty remains.

DISCUSSION

Upper-level ridging will build over the region today through Friday leading to high temperatures 15-20 degrees above average for this time of the year. By Friday the ridge starts to track eastward allowing the upper-level low currently positioned over the western CONUS to advance further east. Southerly flow aloft over the weekend will push moisture into Southwest Montana allowing for a chance of light rain along the lower elevations and light snow above 7000ft. The advancement of the trough through the weekend will allow for temperatures to gradually decrease towards seasonal averages by early next week.

Through the middle of next week, a more unsettled pattern is expected to set up with multiple low pressure systems expected to move through bringing multiple chances for mountain snow and lower elevation rain/snow. A high degree of uncertainty remains in exactly how these systems will play out, especially towards the end of next week. But the overall trend points towards a cooler and wetter pattern lasting through next weekend. -thor
