Even though it’s mid-May, there’s another round of snow impacting portions of the intermountain West. Rain and snow showers are expected in the highest of elevations in Colorado and Wyoming as a low pressure develops and strengthen on the leeward side of the Colorado Rockies. Winter Weather Advisories (light blue) are in effect for south-central portions of Wyoming and Winter Storm Watches (dark blue) are in effect for parts of the Rocky Mountains in Colorado just west of cities like Denver and Boulder.

Snowfall totals will be on the lighter side than a typical snowstorm in the winter season. Nonetheless, several inches of snow are expected to accumulate, mainly Friday night. Total snow accumulations of 8 to 18 inches will be possible in the mountains of western Larimer and western Boulder Counties. The heaviest totals will be found above 9500 feet. Most of this snow will shut off by Saturday night.

You may be thinking: is this snow unusual? It actually isn’t for this region. In Georgetown, CO, one of the locations under the Winter Storms Watch, their average last day of measurable snow is May 17th. Last year, 7.4 inches fell on May 19th, which was the last snowfall of the season.
