WEATHER DISCUSSION: High temperatures continue to slowly climb back to near average as most Sunday daytime highs returned to the 80’s. Expect low temperatures continuing in the low to upper 50’s with mostly cloudy skies and light wings up to 10 mph tonight.
A brief period of weak upper-level ridging built in during the afternoon and early evening across the Northern Rockies Sunday. Ample daytime heating combining with lingering moisture will result in isolated showers and thunderstorms through the evening across Central and North-central Montana. Gusty winds look to be the only concern with thunderstorms that will taper off through the overnight hours.
Monday, expect high temperatures to trend even higher and closer to average thanks to a building Southwesterly flow. Additional showers and thunderstorms will be around shifting northeast starting from SW Montana and moving up towards the Rocky Mountain Front. For Tuesday an embedded wave within the persistent southwesterly flow aloft will bring an increased opportunity for showers and thunderstorms across the region. Thunderstorms during this period will likely be stronger with possibilities of severe thunderstorm risks in Eastern Montana. Other than that, expect scattered showers with occasional lightning, brief and heavy downpours, and wind gusts with storms during the early half of this upcoming week. Daily chances of showers and thunderstorms and consistent high temperatures in the 80’s will be trending Wednesday through the weekend.
