Remainder of August outlook in Colorado

Tomer’s Take:

• In Colorado, the next Monsoon surge arrives 8/25-8/26. It’s a small to medium intensity surge.
• Snow is again possible on the 14ers.
• Telluride Mountain Run 8/27. Forecast below.
• Looking ahead, the Monsoon gradually fades after 8/26 but still remains present at a low intensity until 8/31.
• After 8/31, data suggest the Monsoon continues to fade.

Current Setup

Water vapor satellite shows the suppression of the Monsoon (for now). Orange/red colors = drier air aloft.

Changing Seasons

Mountains of Colorado Timeline:

Telluride Mountain Run 8/27

Hour	4am	10am	Noon	4pm	9pm
%	Dry	Dry	50%	50%	20%
Sky	Clear	P/C	Stormy	Stormy	Clearing

Relative humidity in the middle of the atmosphere suggests the main Monsoon surge from 8/25-8/26 slides away from the San Juan Mountains on 8/27. But, the air is not totally dry with a 50% chance for afternoon thunderstorms over Telluride.

Early September

The latest data suggest the Monsoon fades to a low intensity the first week of September.
