Issue Date: Monday, June 10th, 2019
Issue Time: 9:40AM MDT

Summary:

Cool temperatures and a stable air mass yesterday was a nice break from the hot temperatures we’ve been having the last week. Early morning cloud cover over eastern Colorado decreased throughout the day with mostly sunny skies across the state by the late afternoon. 24-hour maximum temperatures can be seen from MesoWest below, which are quite below normal. The overnight lows reached freezing over the Northwest Slope with Denver hitting the 42°F mark early this morning at DIA. Gusty winds were also reported over the Northeast Plains with the passing jet overhead. As for rainfall, only trace amounts were recorded over the Southeast Mountains from the early morning rain, but everywhere else remained dry.

Melting continued for western Colorado, especially southwest Colorado. No new flooding reports were available as of this morning, but the Flood Warning remains for portions of Conejos, Rio Grande and Mineral Counties. This warning addresses the high flows along the San Antonio and Conejos Rivers in southeastern Conejos County as well as for the headwaters of the Rio Grande and San Juan Rivers. Del Norte still experiencing minor flooding. Willow Creek in north central Mineral County also had flooding issues on the south side of town, so the Low threat today was extended into this area. Areal Flood Advisories were issued for the following: Central Hinsdale County above Lake San Cristobal along Williams Creek, Colorado River near the CO/UT state line, Animas River near Durango, San Juan River at Pagosa Springs, La Plata River at Hesperus, Manco River near Mancos and the Gunnison River above Grand Junction. Flow also increased over the Arkansas River west of Pueblo, but no gages reached above Action stage. For the latest warnings and advisories, see today’s FTB post as well as NWS Grand Junction and Pueblo.

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.
