SPM 06-22-2021: Cool and Pleasant Summer Day

Issue Date: Tuesday, June 22, 2021
Issue Time: 9:30 AM MDT

Summary:

Monday was very calm in terms of precipitation. An early morning line of storms was present east of Limon along the I-70 corridor, before moving south and dissipating through morning, as mentioned in the FTB yesterday. Other than that, conditions remained dry across the state for the rest of the day. No flooding was reported on Monday. For rainfall estimates in your area, including antecedent conditions, check out the State Precipitation Map at the bottom of today’s post.

While astronomical summer technically started on Sunday, Monday felt much more like spring for some of the state. Cooler temperatures were left behind after the two cold frontal passages, with highs in the 60s for the high elevations and 70s for the Urban Corridor and Eastern Plains. The western half of the state wasn’t able to cool as much, and observed highs were in the 80s in the Northwest Slope and Grand Valley and well into the 90s in the Southwest Slope. Daily high temperatures across the state yesterday can be seen in the map below, with data populated from NWS and RAWS stations.

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.
