SPM 08-27-2017: Isolated Showers and Weak Thunderstorms Dotted the High Country

Issue Date: Sunday, August 27, 2017
Issue Time: 10:55 AM MDT

Summary:

Daytime heating and orographic effects battled a strengthening high pressure ridge over the Great Basin in a fight for Colorado weather supremacy yesterday. The high pressure ridge won the overall battle, keeping the vast majority of Colorado dry and warm yesterday. The August sun managed a few wins, however, as isolated showers/weak thunderstorms dotted the high country, resulting in mainly light rain and gusty outflow winds.

Flash flooding was not reported on Friday. For a look at precipitation estimates in your area, please see our 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 accumulation ending time is 6AM of the date shown in the bottom right corner. Also shown optionally are fire burn areas since 2012. The home button in the top left corner resets the map to the original zoom.

Note: We have identified a possible underestimation in QPE over the southwest part of the state. We are working to on this issue, and will provide an update as soon as possible.
