Issue Date: Friday, June 3rd, 2022
Issue Time: 10:00 AM MDT

Summary:

Thursday featured relatively quiescent conditions as sunshine returned for portions of the state. A few showers and storms developed across the southern I-25 corridor in the late afternoon, producing up to 0.10” of precipitation across the Southeast Mountains, Raton Ridge, and southern Southeast Plains. The rest of Colorado remained dry with warming temperatures.

A few small wildfires continue burning west of the Divide, with critical fire weather anticipated today and into the weekend.

There was no flooding reported yesterday. For precipitation estimates in your area over the last few days, check out the 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 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.

SPM 06-02-2022: Rain and Snow Wraps Up

Issue Date: Thursday, June 2nd, 2022
Issue Time: 11:00 AM MDT

Summary:

A shortwave trough moving across the state on the first day of meteorological summer brought continued precipitation east of the Divide for the first half of the day before drying commenced. Precipitation totals across the state were 0.25” or less, with the heaviest amounts approaching 0.50” once again falling along I-76 in the Northeast Plains. A CoCoRaHS observer near Hillrose reported 0.44”, which was the highest observation reported. A few high elevations along the Urban Corridor reported a trace of snow.

The flood advisory for the Green River expired this morning, and flows are slowly returning to normal following the dam release. Flows on creeks and rivers across the state are also returning to normal after the precipitation the last few days.

The updated U.S. Drought Monitor was released this morning, and for the first time in a long time, a small patch of white appeared; this patch across the Northern Mountains is the only region in the state no longer experiencing drought conditions. All five drought intensities saw reductions in percent coverage across the state thanks to the precipitation over the last week.

SPM 06-01-2022: Heavy Precipitation Across Northeast Colorado

Issue Date: Wednesday, June 1st, 2022
Issue Time: 10:00 AM MDT

Summary:

Several meteorological factors came together across the state on Tuesday to produce heavy precipitation across the Front Range, Urban Corridor, Palmer Ridge, and Northeast Plains. Moisture advection on upslope flow, mid-level frontogenetical forcing, and an impressively strong upper-level jet stream led to a blossoming of precipitation by yesterday afternoon across the aforementioned forecast zones. Rain, with snow at higher elevations, continued the rest of the day and into today.

The precipitation fell at moderate to occasionally heavy rates, with the most intense precipitation occurring from Denver northeast along I-76. Precipitation totals along this corridor ranged from 1.00-1.50”, with a few locations recording totals approaching 2.00”; a CoCoRaHS observer near Evergreen reported 1.71”. The rest of northeastern Colorado generally saw anywhere from 0.25-0.75”, with the lowest totals along and south of the Palmer Ridge.

Denver officially recorded 1.22” of rain, making it the largest single-day accumulation since May of 2021:

High elevations of the Front Range once again saw late-season snowfall, with over 16” reported by a CoCoRaHS observer near Idaho Springs! Nine different creeks along the Urban Corridor are running at all-time highs for this day-of-year, per the USGS; none, however, are in flood stage.

SPM: 05-31-22: Winter Weather Advisory; Fire Warnings and High Winds Continue

Issue Date: Tuesday, May 31st, 2022
Issue Time: 10:00 AM MDT

Summary:

Monday saw less precipitation than Sunday, with most rainfall reports showing either no precipitation, or under a tenth of an inch. There was a small amount of precipitation in between Denver and Fort Collins, as other reports indicated 0.1-0.28 inches in areas such as Loveland, Milliken, and Greeley.

Winds have kept up, with 46-62 mph gusts reported along the southern border of the state. In addition, a non-thunderstorm wind gust of 48 mph and a thunderstorm wind gust of 51 mph, was reported associated with a storm in the central plains along the eastern border. Red Flag warnings remained in effect today for a small region of the state today, including the San Luis Valley, eastern San Juan Mountains, and La Garita Mountains. Fire weather in this area continues due to those gusty winds and low humidity, according to the National Weather Service.

Most significantly, a Winter Weather Advisory is in effect for counties with elevations about 9000 feet in the Northern and Central mountains, looking at a possibility of 4-12 inches of snow in that region through tomorrow at midday.

Lastly, the Flood Advisory for Moffat County is still in effect for the Green River, set to expire this Thursday, June 2nd. No flooding has been reported related to this event, and gages nearby report normal levels.
