Weather Forecast: More snow on the way

MISSOULA- After a snowy weekend with some mountain areas getting more than a foot of snow, there's more snow on the way. In fact, there's a chance for snow every day in our 7 day forecast!

Monday continues to bring snow showers to Western Montana. We started out with temperatures hovering right around freezing and as temperatures warm to the upper 30s to mid 40s we'll start to see rain mix in with the freezing precipitation.

We'll see brief periods of accumulation throughout the day but the majority of the snow will melt in the valleys. We still haven't had a 24 hours period with temperatures below freezing so the ground is not as solidly frozen as we need it to be to get good accumulation going.

Winter weather advisories remain in effect until 5PM tonight for areas above 4,000 feet in the Lower Clark Fork, the Bitterroot and Sapphire Mountains, West Glacier, Potomac and Seeley Lake areas. Particular areas to watch out for are Evaro Hill, Highway 200 from Thompson Falls to Plains, Trout Creek to Heron and Bonner to Greenough, I-90 from Lookout Pass to Haugan and East Missoula to Bearmouth, Highway 93 from Sula to Lost Trail Pass, Lolo Pass, Bad Rock Canyon, Essex, Highway 83 from Bigfork to Swan Lake and Seeley Lake to Condon, Marias Pass and Polebridge.

The areas above 4,000 feet could see an additional 4": to 8" of snow on top of what has already fallen. Areas below 4,000 feet have the potential to get 1" to 3". On top of the snow, winds will range from 15 to 25 mph with gusts up to 35 mph particularly in the higher terrains. Make sure you plan your travels accordingly especially if you're going over mountain passes.

A northwesterly flow is set up over the Pacific Northwest pumping system after system our way from the Pacific. That means the chance of snow will linger as one system exits, another one is already on its way.

Wednesday looks to be the best day this week as a weak high pressure builds in, however the chance for snow is still there thanks to the northwesterly flow. Temperatures this week will drop quickly as we move towards the weekend.

Tuesday and Wednesday's highs will only be in the mid to upper 30s. Thursday we'll rebound slightly back into the upper 30s to lower 40s, but by the weekend daytime highs look to stay in the 20s and overnight lows dip down into the single digits!
