A strong microburst snapped several power poles in the desert north of Grand Junction where the outflow winds were most intense. Over 5200 homes were without power for almost two hours. A pickup truck received minor damage from the downed power lines. The ASOS weather station at the Grand Junction Regional Airport measured wind gusts to 60 mph from the winds that flowed out beyond the main microburst impact area where the winds were likely stronger.

Thunderstorm outflow winds blew down power poles.

A wind gust of 60 mph occurred at Grand Junction Regional Airport(GJT) followed 3 minutes later by a gust of 67 mph at Palisade. Small branches were broken off some trees and power was lost for about 5 minutes in the Palisade and DeBeque areas.

Trees and power lines were blown down across 24 1/2 Road between F 1/2 Road and G Road.

A negatively tilted trough moved through western Colorado on the morning and afternoon of Saturday, June 6th, causing a widespread severe weather event that would become the first derecho to impact the Western Slope in well over a decade. Severe storms produced wind gusts upwards of 60 to 80 mph on average with some gusts topping 80 to 100 mph in some areas due to strong downburst winds. There were multiple reports of uprooted trees, downed power lines, at least one roof was torn off with others damaged, and several houses/cabins and vehicles were damaged by falling trees and/or large hail. Very heavy rain also fell which led to flash flooding in some areas.

This storm began on November 30th and continued into December. Please see the November 2007 Storm Data publication for additional information on this episode. A very moist subtropical flow of air spread across western Colorado ahead of a powerful low pressure system. This produced widespread heavy snow across the mountains along with strong winds. This was a relatively warm system initially causing unseasonably high snow levels and mixed precipitation across much of the mountains. After colder air moved into the area moderate to heavy snow impacted some valleys and basins across western Colorado. Heavy rainfall occurred across some of the lower elevations.
