GILLETTE, Wyo. — While Gillette continues to have a 50% chance of thunderstorms today, if any manage to spark off, they could quickly reach severe levels.

The National Weather Service in Rapid City, South Dakota, and the Storm Prediction Center say thunderstorms over northeast Wyoming should be scattered today. However, storms will be capable of producing large hail, damaging winds and a tornado or two.

“The best chance for severe weather will be across northeastern WY through the Black Hills into southwestern SD,” the NWS in Rapid City posted this morning. “While not everyone will experience severe weather, the atmosphere will be supportive of strong to severe storms. Please be weather aware today and monitor the latest weather information. It’s better to have a plan for severe weather and not need it than be caught by surprise.”

Gillette’s risk of severe storms was set at level 2 of 5 by the Storm Prediction Center. The best timing for storms will be 1–11 p.m.

Otherwise today, the high will reach 76 degrees under mostly sunny skies. Clouds will increase in coverage throughout the day. There’ll be a south wind at 6–15 mph shifting to the north this afternoon. Gusts could reach 24 mph. Tonight will be mostly cloudy as the low falls to around 48. Storms could continue until 3 a.m. as winds come from the north at 8–15 mph before turning to come from the west. Gusts could reach 25 mph, the forecast says.

A potentially stormy Fourth of July is forecast with a high of just 67 degrees. There’s a daylong 30% chance of showers and thunderstorms for Gillette, with most of that activity before 4 p.m. The day will otherwise be mostly sunny with northwest winds at 10–18 mph. Skies should clear overnight as the low drops to around 47.

A drier and warmer weather pattern will set up over Campbell County for the weekend. Sunny skies are forecast Friday through Sunday with highs of 76, 79 and 77, respectively. Overnight lows will be in the low 50s with clear skies. Temps should increase further to 84 on Monday and 87 on Tuesday, if the forecast holds up.
