BILLINGS — Mostly cloudy skies and a few scattered snow flurries are falling out of the cloudy skies west of Billings.
The flurries are caused by the dynamics in the air, rising moisture condensed in the next level and producing scattered snow flurries. In Billings, it's not too bad right now, just mostly cloudy and 31 degrees with a southwest wind at 13 mph.
Around the rest of the state, our current temps are mostly into the 20s and 30s, although it was 42 degrees at Sheridan, Wyoming, Tuesday afternoon.
The threat board has a Winter Weather Advisory for western Montana beginning Tuesday night at 6 p.m. and going to 11 a.m. Wednesday. We could see 1 to 3 inches of snow in the valleys and 4 to 6 inches of snow in the mountains out west.
Plus, there is another Winter Weather Advisory for Yellowstone Park and the Teton Mountains until 10 p.m. Wednesday. We could see 3 to 8 inches of snow in the park and as much as 10 to 12 inches in the southwest corner of Yellowstone Park.
Right now, the Doppler radar shows a few minor snow flurries tracking across southern Montana, and the upper-level trough is making its way into the state.
But the big story is a new cold front dropping down from Canada. It will just make its way into northern Montana Tuesday evening, then blow clean through the state by Wednesday morning,
It will be producing snow showers out west and a few scattered flurries in the Billings area as it moves through the state in the morning.
After that, a warm front will sweep across the state and start warming things back up into the 40s on Thursday and Friday.
It will be 32 degrees at 6 p.m. Tuesday, cooling back down to 23 in the morning and back up to 28 degrees by 2 p.m. Wednesday.
We will top out at 32 on Wednesday, then work our way up into the 40s on Friday, through Monday.
TONIGHT: Partly cloudy and cool. West winds 10 to 20 mph. Low 22 degrees.
WEDNESDAY: Partly cloudy with a 40% chance for snow showers in the afternoon. North winds 5 to 15 mph. High 32 degrees.
THURSDAY: Mostly sunny and warmer. Southwest winds 5 to 15 mph. High 39 degrees.
