Monday has been a cool, gloomy day.
On top of that, we're beginning to track showers developing across North Central Montana.
Light rain is expected to continue to lift north through the evening, before turning to snow overnight.
Most spots won't see accumulating snow, but a Winter Weather Advisory will be in effect overnight for Pondera, Glacier, and Toole County.
Most of that area will receive up to an inch of snow, but up to 4 inches will be possible along and west of US 89.
Snow will linger into the morning hours, so there may be some slippery spots and areas of reduced visibility for the Tuesday morning commute.
Snow will turn back to rain through the day Tuesday, with additional showers developing in the afternoon.
Highs Tuesday will be chilly, mainly in the 40s, with warmer spots topping out in the lower 50s.
