Unsettled spring weather will continue, with the chance of showers and isolated thunderstorms in the evenings for the rest of the week. Temperatures will run slightly cooler than average from late May.

An upper low across northern Montana will continue to swing in enough instability for scattered showers and a few late day thunderstorms each day to the rest of the week. Afternoon high temperatures will be mainly in the 60s, with some low 70s possible especially East of Billings.

Heading into the weekend, the upper low will gradually lift to the North. Some showers or thunderstorms possible on Saturday, but Sunday is trending towards drier weather and a pretty nice day overall.

After some scattered showers on Monday and Tuesday, indications are that a ridge of high pressure can build in by Wednesday. That ridge will bring warmer and drier conditions into next week.

Billings forecast:

Today… Generally mostly cloudy, with a chance of showers. Thunderstorm is possible this afternoon or early evening. High of about 65.

Tonight… A chance of showers or thunderstorms before midnight with a slight chance of overnight showers. Low near 47.

Thursday… Once again a mix of clouds and sunshine, with a chance of a late day shower thunderstorm. Around 69 for a high.
