WEATHER PATTERN OVERVIEW: The western upper ridge will remain fairly flat with a WNW flow aloft through midweek with a series of weak shortwaves pushing along the international border. This will keep temperatures slightly below normal. One wave passes through this morning with isolated showers mainly south of Fort Peck Lake. Another wave moves through this afternoon and evening with scattered showers and thunderstorms. Additions waves are expected for Monday night and again Tuesday afternoon and night.

Upper ridge builds into the area for Wednesday, Thursday and Friday with a return to warmer and drier conditions for the end of the week.

Main deviations to the NBM were to spread pops across a larger area for Sunday night through Monday night. Confidence is moderate in timing the various waves the next few days.
