GILLETTE, Wyo. — With an upper-level low to the west and high pressure to the east, Campbell County finds itself in a bit of a sandwich with an abnormally wet atmosphere that’s capable of producing heavy rain during afternoon thunderstorms.

There’s no letup in this pattern for now, according to the National Weather Service in Rapid City, South Dakota.

Scattered showers and thunderstorms are expected today, mainly after noon. The chance of rain is 20%. Today will start off bright with sunny skies and a high reaching 81 degrees. Afternoon storms may start to cool that, leading to an overnight low of 54 before another high of 81 on Thursday. Thursday afternoon carries a 30% chance of showers and thunderstorms through the overnight period as the low drops to 54, according to the forecast.

Friday will repeat the pattern: sunny and warm in the morning with a high of 81, then a 70% chance for thunderstorms in the afternoon. The overnight low will be 56.

The weekend promises to be even wetter, with an early 50% chance of rain Saturday rising to 80% through the day, leading to a chance for thunderstorms in the evening. Expect a high near 71.

Sunday will be largely the same with a chance for rain rising as the high returns from Saturday’s 53-degree low to 68 degrees.

More on the forecast is available from the National Weather Service in Rapid City.
