KEY MESSAGES: - Warm and dry conditions will finish out the holiday weekend before a cold front swings through the region on Tuesday. - Northerly winds will bring smoke south into the area from Canada starting tonight. - Cold front looks to bring scattered showers/thunderstorms early Tuesday (mainly northeast zones) with much cooler conditions by Wednesday. WEATHER PATTERN OVERVIEW: Upper ridge reaching into the region will keep dry and warm conditions over northeast Montana today. A fairly strong closed low pressure system will swing through central Canada on Tuesday, as it tracks toward the Great Lakes. This will drop a cold front into Montana. The northerly flow will allow Canadian smoke to filter south into the area tonight and Tuesday. A few showers or thunderstorms are possible, mainly near the North Dakota border with the front. Winds will increase slightly with the front, but currently are not expected to reach Lake Wind criteria. A second front is expected on Thursday and this one looks to have some stronger winds behind it.
