This system moved east throughout the morning and produced abundant cloud cover over the state. Behind the system, there was a bit of clearing, which allow for some thunderstorms to develop over western Colorado (increased instability). Hail was reported with these storms that varied in size from 0.25 inches to 1.25 inches. A stronger storm in eastern Mesa County and western Pitkin County helped produce 24-hour totals around 1 inch with the multiple rounds of showers. Thankfully, rainfall was gradual enough that it didn&rsquo;t cause flooding issues over the Lake Christine burn area.

Strong winds were also reported in the range of 46 to 63 mph. Leadville reported 1.5 inches of snow, which sits at 10,151 feet, so not too surprising. Rainfall was more stratiform over eastern Colorado with 24-hour totals up to 0.5 inches in southern Washington County.
