DISCUSSION
KEY MESSAGES:
- Gusty Winds and Choppy Lakes Today
- Periodic Showers Through Tuesday, Limited Winter Impacts
- Mid-Week: Inversions and Fog Return
Today through Tuesday: A weak cold front will drop into the Northern Rockies this morning, initiating scattered showers across northwest Montana and north-central Idaho. This precipitation will translate southward into west-central Montana this afternoon while gradually tapering off. Snow levels will hover between 5,500 and 6,500 feet, precluding any significant winter weather impacts. Breezy westerly winds will develop along and behind the frontal passage, with valley gusts of 20 to 30 mph generating choppy conditions on area lakes. These winds are expected to decouple and diminish this evening.
While a few light showers may linger into early Monday, a more organized, widespread wave of precipitation will traverse the region from Monday evening through Tuesday afternoon. Overall accumulations will remain relatively light. With snow levels remaining elevated between 6,000 and 7,000 feet, travel impacts will once again be minimal.
Wednesday through Late Next Week: A dominant upper-level ridge is forecast to build over the region starting Wednesday, persisting through the remainder of the workweek. This pattern will foster strong radiational cooling at night and the development of pronounced valley inversions. Consequently, areas of fog and low stratus are probable, if these inversions become entrenched, they will limit diurnal heating, likely keeping valley high temperatures noticeably cooler than full-mixing model guidance suggests.
Looking toward the end of the forecast period, ensemble guidance indicates the ridge axis migrates eastward. This will open the door to a more progressive southwest flow, reintroducing precipitation chances and effectively scouring out any lingering valley inversions.
AVIATION
A weak cold front will push through the Northern Rockies today, initiating scattered showers and widespread terrain obscurations across northwest Montana and north-central Idaho. This precipitation will move south into west-central Montana this afternoon before gradually tapering off. Despite diminishing shower activity, mountain obscurations will persist through the TAF period. The frontal passage will also usher in breezy westerly surface winds at regional terminals, with frequent gusts of 15 to 25 kts expected throughout the afternoon. Winds will decouple and diminish this evening, leaving only isolated remnant showers across the airspace. Areas of fog and stratus are a concern for Monday morning.
