MISSOULA — Mostly cloudy skies along with a few showers popping up on the radar this morning.

Expect a bit of clearing by late morning and early afternoon. This clearing will lead to hot temperatures with highs in the 90s again Tuesday. Clearing skies will also allow conditions to become unstable with scattered thunderstorms developing by late afternoon and evening.

Most areas across the northern Rockies will have the potential to see a thunderstorm later today, but the area of best development will be across central Idaho into southwest/west-central Montana. Storms that form here could grow strong enough to produce strong winds and frequent lightning. For this reason high fire danger will exist today.

Storms will persist overnight tonight, redevelop again Wednesday, and then persist into the overnight hours again. The best focus of storm development will once again be across southwest Montana.

Storms will once again be a possibility on Thursday, however, not as widespread and temperatures will be slightly cooler with highs in the low to upper 80s.

By Friday and continuing into the weekend, thunderstorm activity will come to an end as sunny, hot and dry conditions redevelop with highs returning to the upper 80s and 90s.
