Summary:

Warm, southwest flow aloft continued across Colorado yesterday, which allowed temperatures to climb well above the previous day’s readings. A couple showers/thunderstorms developed over the high country, as well as along a dryline across the far eastern plains. The activity over the high country resulted in more gusty winds than anything else, as most precipitation reports from CoCoRaHS showed generally a trace-0.2 inches. One storm outperformed the rest in the region, though, producing nearly a quarter inch of rain in Larimer County.

Out east over the far eastern plains, a few severe storms fired off of the dryline, and produced large hail, strong winds, and brief periods of moderate rainfall. The highest precipitation report, according to CoCoRaHS observers, came from Kiowa County where 0.35 inches of rain was reported.

Summary:

Southwest flow aloft continued above Colorado yesterday, resulting in another warm and mainly dry day across the state. At the surface, a front and the return of some moisture from the southeast provided the fuel for a couple showers/thunderstorms. Due to the limited moisture, wetting rain was hard to come by, and the main impacts were gusty winds and lightning. According to CoCoRaHS observers, Boulder County was the big winner with reports of 0.79 inches and 0.34 inches of rainfall. Elsewhere, no more than a trace was reported.

No flash flooding was reported/observed yesterday. For a statewide look at 24-hour precipitation totals, please take a look at the Storm Total Precipitation map below.

Summary:

The upper-level ridge axis was positioned to the east of Colorado yesterday, with southwest flow aloft returning to the region. Embedded within that southwesterly flow was a weak disturbance, which acted as a trigger for a few showers/weak thunderstorms yesterday afternoon/evening. The activity was mainly confined to the Central Mountains, Northern Mountains, Front Range, and Northwest Slope, with a few showers drifting over adjacent lower elevations. With limited moisture in place, any activity produced very little rain. The main impact was gusty outflow winds.

No flash flooding was reported yesterday. Please see the STP map below for a look at precipitation totals from the last 24 hours.

Summary:

Yesterday was marked by mostly sunny skies and above average warmth as an upper-level high pressure ridge built across the state. A few sprinkles over the high terrain during the overnight hours can be attributed to a weak shortwave disturbance that rotated above Colorado as the flow aloft turned southwesterly. Very little rainfall resulted from these showers, with all CoCoRaHS observers that experienced any rainfall reporting 0.05 inches or less.

No flash flooding was reported yesterday, but flooding did continue along portions of the Arkansas River in the Southeast Plains. Please see the STP map below for a look at precipitation totals from the last 24 hours.
