SPM 07-31-2018: Downtick in Shower and Thunderstorm Activity on Monday

Issue Date: Tuesday, July 31st, 2018
Issue Time: 09:00 AM MDT

Summary:

With the upper-level high parked over the desert southwest, northerly flow over the state pulled in very dry air from WY and MT. This limited the rainfall chances during the afternoon and evening hours with the exception of a few isolated storms over the Southeast Mountains, Raton Ridge and Palmer Ridge. Rainfall intensities decreased quite a bit from Sunday due the drier air working its way into the mid and upper-levels of the atmosphere. SNOTEL sites in area recorded 0.1 inches of rainfall on Monday. The highest CoCoRaHS station recorded 0.05 inches in Las Animas County, with most other stations receiving only trace amounts. Radar rainfall estimates were just under 0.5 inches.

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.
