Tuesday and Wednesday will have the most active weather this week. While the chance of precipitation will decrease Thursday and Friday, there is still the possibility of low-elevation precipitation.
A WINTER STORM WARNING has been issued for the Rocky Mountain Front, Lewis and Clark County, and Cascade County for locations above 5000′. Heavy, wet snow will accumulate throughout today and tomorrow, causing low visibility and travel difficulties over mountain passes such as MacDonald, King’s Hill, and Marias.
A WINTER WEATHER ADVISORY has been issued for Broadwater and Boulder Counties for locations above 5000′ in elevation. Boulder Hill Pass, Homestake Pass, and Elk Park Pass will be especially affected, seeing between 3-6″ of total snowfall accumulation.
A FLOOD ADVISORY is in effect for Meagher County, where small stream flooding has been reported.
Dreary and rainy is the story for Tuesday’s weather. As things cool off this evening, snow levels will move into lower elevations, and the chance of snow in the Helena Valley will increase through Wednesday morning.
In total, Helena should expect less than 2″ of snow, while Great Falls can expect less than 1 inch.
