Bone-chilling frigid air rolls in with snow overnight

Story Highlights

  • A Winter Weather Advisory is in effect through Wednesday
  • Roads are expected to turn icy overnight
  • Frigid air will settle in for the rest of the week

Winter weather returns

Most of Montana enjoyed a brief break from winter these past few days, but that's about to change.

The STORMTracker Weather Team says a strong cold front will dive south out of Canada on Tuesday night, sending temperatures nosediving for Wednesday.

The National Weather Service has issued Winter Weather Advisories and Winter Storm Warnings for parts of the state in anticipation of snow moving in, creating hazardous travel conditions.

Drivers are urged to prepare for icy, snow-packed roads through the rest of the week.

Snow forecast

Meteorologist Mike Rawlins says this initial storm system will drop 1-3" of snow across most of north-central Montana.

Some locations could pick up as much as 3-5" closest to the mountains, and more than a foot of powder is expected to fall in the Northern Rockies.

Rawlins says some rain is possible on Tuesday evening before the colder air arrives, but expects a quick changeover from rain to all snow.

Another arctic blast

Say goodbye to the 40s we enjoyed in recent days, because temperatures will crash on Wednesday.

By Wednesday morning, most places are expected to be in the single digits above zero and remain there all day.

With a stiff north wind, wind chills will dip to as low as -20° in some spots.

The frigid air is expected to stick around through the rest of the week, so dress appropriately.
