The National Weather Service has WINTER WEATHER ADVISORY up for central Montana through midnight and for Yellowstone National Park through early Tuesday morning.

Snow accumulations will vary greatly but at the most 1″ – 4″ is possible above 6,000′ and a few higher peaks could see up to 8″ of wet snow.

Most of the snow will quickly melt off by mid week.

Winter Weather Advisory

City by City Forecast:

BOZEMAN: LOW: 39°; HIGH TUESDAY: 69°. Showers will continue into tonight but should diminish by Tuesday morning. Look for patchy valley fog Tuesday morning if skies clear enough overnight. Back to a dry weather pattern Tuesday afternoon.

BUTTE: LOW: 36°; HIGH TUESDAY: 67°. A little more rain is possible for Butte and areas west of the divide but should diminish after midnight. Temperatures will be very chilly first thing Tuesday morning so dress the kids with jackets before sending them out to door to attend school.

DILLON: LOW: 34°; HIGH TUESDAY: 67°. Scattered showers will continue for Dillon and many nearby mountain ranges will see higher elevated snow heading into tonight. The wet weather will be ending tomorrow but morning lows will be close to freezing Tuesday morning.

WEST YELLOWSTONE: LOW: 26°; HIGH TUESDAY: 61°. Mostly scattered rain showers to continue for West Yellowstone but could mix with a few snow flakes. The wet weather pattern will diminish into Tuesday morning but as skies clear by sunrise temperatures will be very frosty.


Slow moving upper level Low is parked over Montana Monday producing widespread rainfall across the state and higher mountain snow. This storm will continue to spin off to the ENE overnight and drier weather to begin west of the divide overnight but more rain to continue east of the divide into Tuesday morning.

Temperatures overnight will be very chilly and if skies clear enough look for lows to fall down close to freezing in SW Montana and possible below freezing at higher elevations. I recommend covering up flowers and gardens tonight to be safe to avoid a killing frost.
