Today a weak low pressure system skirts the area, as our upper level flow goes from Westerly to northwesterly, while a strong high-pressure Ridge builds in to the west. Temperatures are expected to be warmer under mostly sunny skies, and dry conditions, with some Northwest breezes.

On Thursday high-pressure ridging builds in stronger across the area as low pressure moves off to the east, For warmer temperatures, mostly sunny skies and not much wind expected.

On Friday we expect a low pressure system from the northwest US to clip the area with increased winds and dry conditions across the area. Only a few clouds are expected south of this low pressure system.

Saturday through Monday a stronger low pressure system drops in from out of the Northwest, with increased moisture and a good chance for showers and thunderstorms across western Colorado, including Aspen Snowmass, especially on Sunday. Temperatures are expected to cool down Sunday and Monday as this happens.

By Tuesday and Wednesday low pressure is exiting and a high pressure ridge builds in. We expect a west/ northwest wind flow across the area leaving most of western Colorado closed off to any moisture, so the air will be much drier, skies mostly sunny, and temperatures on the rise.

LONGER RANGE FORECAST
By next Tuesday and through the rest of June it looks like we will have a high pressure ridge located to the east, with low pressure still remaining persistent across the Northwest US, causing an open door to monsoonal moisture from out of the Gulf of Mexico, and resultant increased chances for thunderstorms and showers in Aspen and western Colorado, otherwise temperatures will be summer-like and warm. Mostly sunny skies are expected overall, with periods of mostly cloudy skies in the afternoon hours, as is to be expected during thunderstorm season.
