DISCUSSION

KEY MESSAGES:

- Mostly unsettled weather with valley rain, mountain snow, and gusty west winds today and Sunday

- Snow over mountain passes on Monday morning

- Unsettled spring-like weather will continue into the middle of next week with a warm-up later in the week

Radar returns this afternoon are indicating a southwest to northeast oriented line of showers moving across the Northern Rockies. These showers are inline with a weak shortwave trough and associated cold front. Increasing clouds, widespread showers, and increased westerly winds will accompany this system through this evening. Precipitation will stay in the form of rain below about 6000 feet.

Moist westerly flow will keep some showers in the forecast for Sunday. The best chances for precipitation will be across northwest Montana and north-central Idaho in the morning, spreading southward across the remainder of the Northern Rockies in the afternoon. Snow levels will fall to about 5000 feet for northwest Montana and the Clearwater range in Idaho. By Sunday night, a trough of low pressures will deepen over the Northern Rockies, bringing more widespread precipitation in time for the Monday morning commute. This system will have some colder air associated with it, so expect snow levels coming down to about 4000 feet for northwest Montana and north-central Idaho. Warm road temperatures should keep travel impacts from snow out of the valley locations and limited to the mountain passes. Lookout, Lolo, Lost Trail, and Marias passes could all pick up a few inches of snow on Monday morning. The position of an upper level jet streak and an unstable atmosphere will be conducive to windy conditions at the surface on Monday afternoon and evening.

Ensemble model solutions are showing an unsettled pattern of westerly flow with some embedded shower activity, mostly for northwest Montana and the Clearwater range in Idaho, through Tuesday. Temperatures for the week will be mostly seasonable, with Thursday being the warmest. Low pressure is the most likely solution for next weekend, though timing and amplitude of the trough are still very much in question.

AVIATION
A line of showers, visible on radar imagery, will continue moving through north-central Idaho and western Montana this afternoon and evening. These showers will bring lowered ceilings, reduced visibility, and gusty winds of 15-25 knots.
High-resolution models indicate that winds will gradually decrease this evening, though isolated showers may persist overnight, particularly in northwest Montana. By Sunday, a trough is expected to dig into the Pacific Northwest, bringing increasing westerly winds along with showers and isolated thunderstorms by the afternoon.
