KEY MESSAGES: - A cool rain is possible tomorrow (Tuesday) in parts of the area. Some mix with snow is possible from Whitewater to Plentywood. - Warmer and windy conditions can be expected Thursday. - Cooler and more unsettled conditions can be expected into the weekend. WEATHER PATTERN OVERVIEW: A more unsettled pattern can be expected this week as an upper trough develops off the Pacific Northwest coast through Tuesday. This will break down a ridge over the Northern Rockies that will allow more unsettled conditions for the region that continues into the weekend. Broad W-SW flow over the area today will send a disturbance east across eastern Montana Tuesday. Wet conditions over central Montana will dry a bit but colder air over Sask will filter in and possibly bringing a mix of rain and snow to some areas north of Highway 2, generally near the Canadian border though. A stronger system is possible Wednesday night into Thursday with stronger winds. Isolated rain showers look to stay near the Canadian border.
