We can expect 2-4 inches accumulation of snow late Monday and into Tuesday in the Treasure Valley, with 5-10 inches possible in the mountains.

As of Sunday morning, Ontario and Mountain Home were getting hit with snow.

After this storm system moves off to the east and out of the area on Tuesday afternoon, arctic air will filter in over the Treasure Valley, resulting in a low of 2 degrees on Wednesday morning.

Normally, we won t see this kind of storm with these extremely low temperatures this early in the season, Lantz said Sunday morning. This is something that normally doesn t arrive until late December or early January, so we don t want it to catch anyone by surprise because it could be dangerous if you re out in the elements unprepared.


Many people are traveling this time of year for the holidays and the snow can have an affect on both vehicle and air travel. If you're traveling by air, you'll want to keep in contact with your airline to make sure your flight has not been delayed or canceled.

If you're on the road, you'll want to leave extra time to get to your destination. Poor visibility is common and drivers should slow down for the conditions. Take the time to scrape or defrost your windows before you ever set out on the road.

Check out the road reports and traffic cams before you go.

Some places require chains this time of year, so you'll want to make sure you have the proper equipment. If you do use chains, try putting them on your car in advance as practice so you will know what to do if you are required to use them.

It's also advised that you have some basic snow equipment in your car. A safety vest, water and food, and a foldable shovel are all good things to have handy in case you become stranded in the snow.

Advice for pet owners

Rick reminds people to watch your pets because it s going to be too cold an environment for them. Make sure they have a warm place. Also, keep in mind that if they have an outdoor water dish, it is likely to freeze in this weather.
