Summary:
As the upper-level ridge shifted east of the state, the approach of the next upper-level trough brought a bit of energy and moisture back into Colorado, resulting in a few isolated showers/weak thunderstorms across Northern Colorado. The bulk of the activity was confined north of I-70 and west of the Continental Divide where the best mid-level moisture resided, but a few gusty showers did impact the Urban Corridor during the late evening/early nighttime hours. Generally speaking, rainfall rates were light due to dry air near the surface, with the best rainfall, relatively speaking, falling over the High Country north of I-70. As far as storm reports are concerned, the gusty showers that moved over the Denver metro during the evening resulted in the only significant reports of the day:
58 mph wind gust: 2 miles SW of Rocky Flats (Jefferson County)
56 mph wind gust: 2 miles SSW Broomfield (Broomfield County)
No flash flooding occurred yesterday. For a look at precipitation estimates in your area, please see the State Precipitation Map below.

The map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE) across Colorado. The map is updated daily during the operational season (May 1 – Sep 30) by 11AM. The following six layers are currently available: 24-hour, 48-hour and 72-hour total precipitation, as well as maximum 1-hour, 2-hour and 6-hour precipitation over the past 24 hour period (to estimate where flash flooding may have occurred). The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. The accumulation ending time is 7AM of the date shown in the bottom right corner. Also shown optionally are fire burn areas (post 2012), which are updated throughout the season to include new burn areas. The home button in the top left corner resets the map to the original zoom.
