In Monarch and, more broadly, across the state of Montana: The rest of the day will see mostly cloudy skies with cool temperatures ranging from 45 to 48 degrees Fahrenheit. Light winds from the north, averaging around 7 mph with gusts up to 10 mph, will be noticeable but gentle. There is a high likelihood of rain, with some areas experiencing approximately 0.02 inches of accumulation. While the rain is expected to be light, it could linger into the afternoon, so it’s a good idea to have an umbrella or raincoat handy if you plan to be outdoors. Temperatures will remain steady, and the overall weather suggests a damp, chilly afternoon. Be prepared for the possibility of wet conditions if you’re heading out later today.
