BOISE -- Fall temperatures could give way to snow this week as a wave of showers rolls through Idaho.
How much snow are we talking about?
The state's highest mountain areas could see 7 to 10 inches of snow by Thursday, according to KTVB Meteorologist Larry Gebert. However, Gebert also says many valley locations will only experience a rainy drizzle. Areas in between could see a rain / snow / ice mixture.
The wintry weather won't last long, however. That's because temperatures are expected to rise nearly 20 degrees over the weekend.
TEMPERATURES DROP FIRST
The high temperature in Boise on Wednesday is expected to be a chilly 57 degrees. Overnight Wednesday, most valley locations will see temps dropping into the 40s. Mountain communities, including McCall, Ketchum, and Stanley will see freezing temperatures and could experience some snowfall.
You can expect a dusting of snow in the Boise foothills and possibly a few inches on high areas like Shafer Butte on Wednesday and Thursday. Locally higher amounts of snow could fall in places like the Trinity Peaks, Steele Mountain, and the Soldier Mountains.
WESTERN, CENTRAL IDAHO
NWS forecasters say snow amounts from 3 inches around 6,500 feet to as much as 10 inches above 9,000 feet are possible in the West Mountains, Salmon River Range and parts of the Sawtooth Range.
Predictions for the southern and eastern highlands range from 3 inches at 6,500 feet to as much as 8 inches above 8,000 feet.
Drivers are cautioned to prepare for hazardous, possibly snowy conditions above 6,000 feet on Wednesday and Thursday.
Highway officials say low temps also mean that ice could be a danger, especially during morning hours.
KTVB Meteorologist Larry Gebert says it's important to remember that because the ground isn't yet frozen, even small amounts of snow can lead to stuck vehicles. Those planning to hunt in mountain locations or take part in fall recreation this week should be prepared for a challenge.
WYOMING AND MONTANA
Highway officials have announced the temporary closure of the Beartooth Highway near Yellowstone National Park due expected heavy snow.
This high elevation section of US-212 will be temporarily closed at 6:00 p.m. Tuesday evening. After the storm passes, crews will re-evaluate the status of the road.
In Wyoming, the closure extends from Long Lake Gate to the intersection of WY-296, the Chief Joseph Scenic Highway. In Montana, the road will be closed at the bottom gate 13 miles south of Red Lodge.
