Summary:<\/h3>\n

Saturday saw an increase in cloud coverage and cooler temperatures west of the Continental Divide<\/span> due to a shortwave<\/span> entering the state ahead of the eastward progression of a larger trough<\/span> to the west. By evening, there was widespread<\/span> thunderstorm activity along the Western Slopes and Grand Valley, though the main threat from these initial storms was high winds. Gusty, high winds from thunderstorms exceeding 45 mph were reported all along Western Colorado, from Craig in the north to Cortez in the south – and Rifle had winds up to 63 mph!<\/p>\n

As daytime heating waned, storms became more stratiform in nature rather than convective. This allowed for widespread<\/span> showers in the overnight hours, however with low rainfall rates due to very dry atmosphere that had to become saturated first earlier in the day. Still, there were some notable 24-hour rainfall totals and light snow was even reported on some mountain peaks:<\/p>\n
