BILLINGS – At 2 p.m. Thursday, you can already see the towering cumulus clouds firing up on the other side of the Beartooth Mountains.

This is our next supply of moisture getting ready to move into the state and push over into south-central Montana.

Afternoon temperatures are already reaching into the upper 70s and low 80s with mostly sunny skies.

This will create additional lift in the atmosphere, which could cause thunderstorms to become severe.

In fact, our thunderstorm outlook for today shows a marginal risk of severe thunderstorms across northern Wyoming and south-central Montana.

The threat board currently is filled up with only flooding issues the same ones we been dealing with all week.

The Musselshell River at Roundup is still forecast to go above flood stage on Friday, while the Yellowstone River at Miles City is forecast to get close to flood stage.

The Doppler radar shows the next wave of showers of thunderstorms already moving in from the southwest.

The computer models put those thunderstorms into the Billings area around 6 p.m. Thursday.

Then another wave of moisture moves into the Billings area around 7 a.m. and will get caught up in a northwest flow, giving Billings a chance for showers all day Friday.
