Boise, ID – A new weather system is bringing rain, breezy conditions and accumulating mountain snow to southwest Idaho and southeast Oregon beginning Sunday, Nov. 15, with colder temperatures and falling snow levels expected through Tuesday.
According to the National Weather Service in Boise, precipitation will increase Sunday and continue into Tuesday, while temperatures and snow levels gradually decrease across the region.
Sunday: Rain Returns, Mountain Snow Begins The approaching system will bring breezy winds and increasing precipitation across eastern Oregon and west central Idaho on Sunday.
Snow levels are expected to range between 5,500 and 7,000 feet, with light snowfall developing in higher mountain elevations.
Most lower elevation communities, including the Boise area, are expected to experience rain rather than snow.
Monday: Colder Temperatures and Accumulating Snow By Monday, Nov. 16, precipitation will continue across eastern Oregon and increase across southwest Idaho.
The National Weather Service expects snow levels to fall to approximately 5,000 to 6,500 feet.
Accumulating snow is forecast across higher mountain elevations, potentially affecting travelers heading into mountainous areas.
Daytime temperatures in lower valleys could reach only the mid 40s to mid 50s as cooler air spreads across the region.
Tuesday: Snow Levels Fall as Low as 3,500 Feet Tuesday, Nov. 17, could bring the most significant temperature change of the three day period.
Snow levels are forecast to drop to between 3,500 and 5,000 feet, allowing accumulating snow to reach middle mountain elevations.
Precipitation should gradually decrease from west to east throughout the day, although breezy conditions may continue.
Valley high temperatures are expected to range from the low to upper 40s.
Motorists traveling through mountain passes should prepare for changing road conditions, reduced visibility during precipitation and potentially slippery surfaces.
