SPM 06-29-2019: Summertime in Full Swing

Issue Date: Saturday, June 29th, 2019
Issue Time: 9:10 AM MDT

Summary:

Hot temperatures were the main weather story across Colorado yesterday, as strong, high pressure aloft built over the center of the United States. Widespread upper-90s and a few lower-100s were draped across the lower elevations of eastern Colorado, 80s and 90s in lower mountain valleys, and 50s and 60s in the higher elevations. There was enough residual moisture for intense daytime heating and orographic effects to produce isolated, late-day thunderstorms, mainly over/near the higher terrain. A few thunderstorms moved over the Urban Corridor after 7 PM. The main impacts of all shower/thunderstorm activity were periods of light rainfall and gusty winds at 40-50 mph. A few stronger gusts were recorded:

58 MPH: 3 miles WSW of Longmont (Boulder County)
57 MPH: 5 miles N of Elizabeth (Elbert County)
52 MPH: Denver International Airport (Denver County)

No flash flooding was reported yesterday. For a look at precipitation estimates in your area, please see the 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 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.
