SPOKANE, Wash. -

Cold temperatures are no big surprise in Spokane, however, wind chill warnings are not so common. Heading into Saturday that wind chill could push the thermometer down to -15 degrees and those temps call for extra precautions.

Miss Randall's kindergarten class at St. Charles Catholic School a quick refresher on bundling up for cold weather.

"Oh, he's got a hood so we're going to use this one, wow! Oh, two gloves because we have two hands, so there we go and we push it, push it, push it down," said Randall as she tugged a glove on a student.

From gloves to hats, scarves and jackets these students are keen on keeping warm.

"Because Mr. Jack Frost might bite your cheeks or bite your nose, so look at that can you barely see him?" said Randall.

When temps drop below 20, Miss Randall holds recess inside. In Spokane Public Schools that decision is left to the principal of each school.

"It's so very cold. We heard it was 1 degree earlier today so super cold," said Randall.

And the National Weather Service says temps will drop even more overnight with a Wind Chill Warning in effect until 10 a.m. Saturday.

"You see -13, Spokane -15, Coeur d'Alene, Bonners Ferry -16," said Ty Judd, meteorologist for the National Weather Service.

The last wind chill warning issued in Spokane was December of 2008.

"That's what wind is, it's the movement of air from high to low pressure so you start seeing the high here the low here so you start seeing the winds go like that," said Judd, gesturing to one of his three monitors.

Judd says frostbite and hypothermia are a real concern during these lows.

"You know, how long you've been outside, what are you wearing? Sometimes it can occur in as little as thirty minutes," said Judd.

The wind chill warning in most of Eastern Washington continues in to Saturday. Farm animals and pets should be given shelter and make sure outside water isn't frozen over. And of course bundle up those toes and fingers when playing outside.

"And if they don't have everything they don't go outside," said Randall.

Luckily Miss Randall keeps back-up gloves and hats in the classroom for those occasions.

"Just be safe, be smart, use your common sense, a lot of time that's the best advice you can have," said Judd.
