SPM 09-28-2019: Scattered Showers Dotted the State

Issue Date: Saturday, September 28th, 2019
Issue Time: 9:00 AM MDT


Yesterday began with ample sunshine across Colorado, but clouds increased quickly during the afternoon/evening hours as an upper-level disturbance shifted across the Rockies. With this disturbance, scattered showers developed and moved from west-to-east, producing periods of light-to-moderate rainfall and gusty winds. The greatest coverage of rainfall occurred across northern Colorado where a bit more moisture was present, with more isolated coverage to the south. Showers diminished early this morning as the disturbance lifted out of the state and into Wyoming/Nebraska.

No flash flooding was reported 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 vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas. The home button in the top left corner resets the map to the original zoom.
