Aspen Highlands Discussion

Updated for Saturday, July 21, 2018

Today and Sunday, we see an increase in thunderstorm potential, as increased moisture and slight overhead instability move in from the Southwest. Mostly sunny mornings, mostly cloudy afternoons with nearby (or overhead) thunderstorms, and slight cooling. CM

Longer-Range:  We are expecting a continuance of scattered showers and thunderstorms due to increased instability plus moisture from out of the Southwest, then decreasing to isolated as we move through most of next week. This pattern continues through the rest of July; Isolated afternoon thunderstorms otherwise mostly sunny, and summer-like very warm temperatures. CM
