Weekend showers, a soaker coming next week
Showers will develop each afternoon this weekend in western and southwest Montana. Expect the most shower coverage on Saturday with a chance for a little rain from Kalispell all the way to Bozeman. Early risers may see some rain around the Gallatin Valley and in the backcountry of the Bitterroots. Morning lows will be in the 40s with upper 30s at higher elevations. Afternoon highs will remain cool in the upper 50s to mid 60s.
Sunday will be a little warmer and a bit more dry. Only a few isolated showers are expected, mainly near Yellowstone north to Butte in the evening. Highs will graze the 70s briefly in the afternoon west of the divide with areas further south remaining in the 60s.
A strong low pressure system will arrive late Monday and sit over central Montana for most of Tuesday. Most of southwest and central Montana will have a shot at 1 to 3 inches of rainfall by Wednesday morning. Heavy rainfall could spread as far west as the Missoula and Bitterroot valleys depending on the storm's track. For now Kalispell sees much less rain than areas further south. Snow will fall in the mountains above 7000 feet. Temperatures in the valleys will only reach the mid 50s to around 60 degrees.
River levels will jump 1 to 2 feet by next Thursday as they try to send all the fresh rain downstream. This will bring flooding concerns to many areas as they reach action stage or minor flood stage. Stay with us this weekend as we refine the forecast and try to pinpoint who gets hit the hardest by the heavy rain.
