Rocky Mountain National Park Weather Forecast
The wettest and stormiest weather of the summer season shrouded the Park over the past week.

Week in Review
High levels of absolute moisture (1.5 – 2.0 cm of water vapor over Niwot Ridge) within a deep moist plume stretching from the southwestern US through Colorado was the main culprit for the persistent stormy soaking.
Numerous rainfall measurements from Indian Peaks to RMNP totaled 1.5 – 3.0 inches of liquid over the period in the sub-alpine zone. With radar estimates of 2-3 inch-per-hour rainfall rates from some of the more intense storms, locally higher rainfall totals are likely.
Eli’s Diamond attempt on the morning of 8/4 was preceded by a multi-hour deluge the prior afternoon and evening. Radar reflectivity indicated hail, groupel, and heavy rain over Longs, all of which were verified by the soggy, slushy aftermath on the approach.

The Upcoming Week
While our typical August thunderstorm cycle has plenty more to give, somewhat of a reprieve is forecast for part of the upcoming weekend.
Drier air is expected to work its way in on Friday (8/6), and is likely to produce one of the best weather days of the period over the Park. These good tidings will continue to a lesser degree on Saturday (8/7), before another shot of juice moves in on Sunday.
Late afternoon showers and storms are still possible on Friday and Saturday, however they would be more isolated in aerial coverage and much less intense than those of recent days.
This type of reduced activity may reemerge early next week, if the current forecast tendency for additional drying verifies.
