Happy St. Patrick's Day! It's going to be a cooler day than yesterday. Highs in the 40s should be expected for outdoor festivities. The atmospheric river has moved south, affecting the Billings area today and tomorrow. We will see scattered snow showers develop this afternoon in the western mountains.

Tomorrow will be a slightly cooler day with highs in the 30s and 40s. Scattered afternoon snow showers are expected once again.

Wednesday will be a nice break with mostly sunny skies and high temperatures approaching 50 degrees.

The first day of Spring will be unsettled with rain and snow along a cold front. It will also be windy. The highs will reach the 40s and 50s.

We stay active through the weekend, with a significant warmup coming next week.
