BILLINGS – It is another beautiful day here in Billings, but we do see a few clouds starting to gather on the other side of the Beartooth Mountains.
Those clouds are part of a shortwave weather disturbance that’s been gathering there for a few hours and will eventually push their way into the Billings area later this evening.
Our thunderstorm outlook for today does show isolated showers beginning to our southwest. They then increase in size and intensity as they travel east as the day goes on.
We expect an increased risk of severe thunderstorms for Miles City, Baker and Bismarck, N.D.
Tomorrow we only expect isolated showers across Montana. The bigger storms will be a little bit further east and in the Dakotas.
On the threat board, only a Red Flag Warning remains for Johnson County in Wyoming. There, high winds and low humidity could create erratic fire behavior until 8 p.m. Monday.
The Doppler radar shows a few showers developing in northwest Montana, and the clouds are beginning to gather over the Beartooth Mountains in the southwest.
Our high resolution computer model shows those clouds in the Beartooths will turn into showers and eventually push their way to the Billings area by 5 p.m. tonight.
Those storms will become severe by 10:30 p.m. in extreme Eastern Montana and over by Miles City.
Then, by Tuesday afternoon two more shortwave disturbances will move our way, one to the North of Billings and the other to the Southeast.
Tonight: Mostly cloudy with a 50 percent chance for scattered showers and thunderstorms in the evening, then isolated showers overnight. North winds 5 to 15 mph. Low 53 degrees.
Tuesday: Mostly sunny with only a 20 percent chance for afternoon showers and thunderstorms. North winds 5 to 10 mph. High 75 degrees.
Wednesday: Mostly sunny, dry and warmer. West winds 5 to 15 mph in the morning becoming southeasterly 5 to 10 in the afternoon. High 78 degrees.
