Show Information for:
Start of Dispersion Forecasts from Northern Rockies Predictive Services.
The weather will continue to be cooler than normal through the weekend into next week as a broad area of low pressure moves through the region. Friday and Saturday it will be windier with valley showers and steadier mountain snow as a disturbance passes across ID into MT. This will support good dispersion most areas. The flow aloft becomes westerly and a bit less disturbed early next week so while it continues to be cool, shower activity is expected to decrease but not all together quit.
Clouds may be a limiting factor on dispersion keeping surface heating from supporting initial smoke lift.
