WATCH: Time-lapse of fog rolling into the Black Hills Monday morning

Easterly winds monday morning helped bring moisture rich air into the Black Hills, using the rising terrain to condense into an ocean of fog

It was the perfect morning for weather enthusiasts as swirling clouds enveloped the Black Hills in great waves Monday morning. Fog usually has a tough time cresting the hogbacks into West Rapid City, but eventually overcame the drier air.

Dew points are expected to rise over the next couple of days, particularly East River, so it’s going to start feeling a little muggy over the next couple of days. The fog is great evidence of this increase in moisture.

Keep an eye out for a few isolated thunderstorms through Tuesday, and more scattered storms Wednesday through Friday!
