SPM 08-18-2019: Accumulating Rain Confined to the Eastern Plains

Issue Date: Sunday, August 18th, 2019
Issue Time: 9:15AM MDT

Summary:

Not much rainfall yesterday as westerly flow mixed out moisture from west to east. Storms that made it into the eastern plains, before falling apart, were able to gain a little strength. Radar showed an area of weak thunderstorms forming over the eastern plains during the afternoon and evening where slightly better moisture was able to hold on. Totals up were just over 0.5 inches with most areas below this mark. Hail reports were up to 1 inch with these storms with the largest hail report around quarter size. There were additional light showers over the Northern Mountains and Northern Front Range, but totals were under 0.25 inches (so they aren’t shown below). The big report of the day was a 65 mph wind gust in Moffat County where there was a Red Flag Warning. Surface winds yesterday ranged from 10 to 25 mph over this area with relative humidity values in the teens. As anticipated, flooding was not reported.

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.
