SPM 06-08-2020: High Winds Return Without Much Rainfall

Issue Date: Monday, June 8th, 2020
Issue Time: 10:35AM MDT

Summary:

High winds continued on Sunday, although nothing like the historical derecho event on Saturday. For the most part, it was quiet behind the trough on the rainfall front as moisture mixed out. There were some morning and afternoon showers over the Northwest Slope as it remained in an area where mid-level was still occurring with a little moisture. These storms were high-based and generated only about 0.05-0.10 inches of rainfall. High wind gusts were recorded across western Colorado in the 45-55 mph range with the strong jet overhead. Even stronger winds were produced over the eastern border during the afternoon and evening hours where ASOS stations recorded between 45 and 65 mph gusts. This caused visibility to drop to nearly zero in eastern Yuma County. This was again due to the trough overhead and lee surface trough helping to tighten the surface gradient.

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.
