SPM 08-17-2018: Increased Moisture Bumps 24-hour Totals over Western Colorado

Issue Date: Friday, August 17th, 2018
Issue Time: 10:00 AM MDT

Summary:

Another round of showers and thunderstorms fired over the southern high terrains on Thursday. Dry air continued to be entrained from the north, so not much action over the northern half of the state again. Totals were able to increase due to a slight upward tick in low-level moisture over western Colorado. A CoCoRaHS in Delta County reported 0.42 inches. Unfortunately, still no rain for Grand Junction. Pagosa Springs got 0.22 inches and its north, the Weminuche Creek SNOTEL station reported 0.5 inches. These were similar totals to stations over the western San Juans. A station in Del Norte reported 0.41 inches. The highest CoCoRaHS report for the day was in Pueblo, which reported 0.63 inches. Radar estimates indicate storms over the adjacent eastern plains produced rain rates just over 0.5 inches/hour.

Flooding was not reported on Thursday though there was an areal flood advisory and flash flood warning issued from the Pueblo office in the early evening. To see how much precipitation fell over your area, scroll down to 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.
