Low pressure off the California coast and a low over the SW U.S. is producing a wrap-around effect with scattered showers and thunderstorms across the southern half of Beaverhead, Madison and Gallatin counties this afternoon.
The showers and thunderstorms are tracking from east to west which is unusual to see but the upper level low pressure system to our south is spinning counter clockwise.
This pattern will continue to play out over the next couple of days. There is a very cool front digging down into Montana from the north but its impacts will hardly be noticeable with temperatures falling just a few degrees Wednesday through Friday.
By the weekend, temperatures will climb again and mid 70s to lower 80s, especially by Mother's Day.
The overall weather pattern through the next 7 days is DRY! This is not typical for the middle of May. We usually see 2" to 3" of rain this month and so far Butte has only measured .04" and Bozeman MSU .13" and Dillon airport with .03".
I'll have the latest STORMTracker forecast for you tonight at 5:30 and 10 p.m.
