Today, conditions will remain generally cool and unsettled. Expect rain showers to be rather widespread across North Central Montana as the upper-level trough makes its way through the Northern Rockies today. Most of theses showers and thunderstorms will bring nothing more than some brief rainfall, though some small hail is possible with stronger storms. With this trough overhead, temperatures will remain slightly below average.

Even with this first trough axis clearing the area Monday evening, a second weak shortwave will move across on Tuesday, helping to kick off a few scattered showers, though these should generally be confined to the Plains on Tuesday. Showers and storms will become more widespread on Wednesday as a more substantial upper level trough digs into the area, providing more atmospheric support for widespread showers and thunderstorms, though upper level winds will generally result in these storms remaining weak and disorganized. Independence day will see showers gradually end as this system moves east, though temperatures will generally remain on the cool side with most lower elevations topping out in the low to mid 70s.

MONDAY: Chance of showers and thunderstorms. Mostly sunny then partly cloudy with highs in 70’s and lows in 50’s.

TUESDAY: Chance of showers and mostly sunny, highs in 70’s.
