The weather in western Montana has been downright balmy, considering we're coming to the close of the Thanksgiving weekend, but, that could change by Sunday night into Monday.

Meteorologist Lance Van den Boogart with the National Weather Service Office in Missoula said a cool wind from the north just might bring light snow all the way down to the Missoula valley floor.

"We'll be coming under a trough here starting Sunday," Van den Boogart said. "What that'll mean is some cooler air from Canada will be headed our way, and with that cooler air, the snow's going to be able to make it down to the valley floor, and there's some possibility of that with some moisture on Sunday, but then on Monday a stronger system is coming through with cooler air in place, and that could lead to snow-covered roads here in the valley."

Van den Boogart said the mountain passes have already seen some snowfall, so this new system won't bring too much change.

"The big difference will be for the valleys that have been pretty warn for the last couple of weeks," he said. "We'll have just enough valley snow to cover the roads, that's a few inches possible if this system comes through as predicted. The system coming through on Monday will probably last about 24 hours, and then there'll be a break for a couple of days."

Van den Boogart said the high temperatures on Sunday will be in the upper 30's, with lows Sunday night into Monday in the mid 20's, with highs in the low to mid 30's by Monday.

The snow, if it comes, will be too late for the general rifle season, which ends Sunday evening.
