MISSOULA — No major storm systems on the horizon, however, light valley rain and snow along with mountain snow will start today then continue through the weekend.
The valleys of northwest Montana will have a chance to see some very light rain, snow or evening freezing rain Tuesday morning. These showers will become more widespread this afternoon and evening across all of western Montana. Showers will remain very light with little impacts to roads expected.
Wednesday through the weekend, the region will remain under a ridge of high pressure. With the ridge axis set to our east, the northern Rockies will be under a southwest flow.
This weather set up usually means two things: Above average temperatures as winds are flowing out of the southwest and above average precipitation.
However, due to the dynamics of a high pressure ridge precipitation will remain very light with only occasional showers expected in the valleys. The mountains on the other hand will see more persistent although light snow showers which will continue to add to the mountain snow pack through the weekend.
