Summary:<\/h3>\n

Active weather continued across the state on Monday as another shortwave trough<\/span> moving across the Intermountain West and Northern Rockies produced showers and storms over Colorado, including more severe weather. Convection<\/span> developed yesterday afternoon over the high terrain along the Divide<\/span>, before pushing off eastward into the adjacent plains where better moisture and instability was encountered.<\/p>\n

Precipitation amounts along the Urban Corridor were generally T-0.25”, with locally higher amounts of 0.25”-0.75” in the vicinity of Fort Collins and Colorado Springs. Storms over the Northern Mountains and northern Front Range prompted the Boulder WFO<\/span> to issue Flood Advisories for both Grand and Larimer Counties, including the Cameron Peak and East Troublesome burn scars. The advisories were issued for minor flooding of small streams and low-lying\/poor drainage areas; a station near Grand Lake measured just under 0.50” of rainfall in approximately 90 minutes. Thanks to fast flow aloft and storm motions of 35+ mph, no flooding was reported across either burn scar.<\/p>\n

The heaviest precipitation yesterday occurred in a swath from the southern Urban Corridor across the Palmer Ridge and into the Southeast Plains. Healthy rainfall amounts of 0.50-1.50”, with locally higher amounts, were widespread<\/span> across this corridor. Some noteworthy observations include:<\/p>\n

• 1.71” 3 miles SW of Lamar
• 1.14” 1 mile NE of Peyton
• 0.92” at Lamar Municipal Airport
• 0.86” 3 miles NNE of Cheyenne Wells<\/p>\n

The town of Lamar was particularly hard hit, with 1.75” hail and an 82-mph thunderstorm wind gust recorded at Lamar Municipal Airport. The Pueblo WFO<\/span> issued a Flash Flood<\/span> Warning<\/span> for west-central Prowers County including Lamar after local law enforcement reported “widespread<\/span> flooded roads and other minor flooding.” An automated station 3 miles SW of Lamar reported 0.30” and 0.40” of rainfall in consecutive 5-minute periods, which translates to 0.70” in just 10 minutes!<\/p>\n

Piles of hail all over Lamar. And the trees took a lot of damage. It dropped to 66° here. #cowx<\/a> @NWSPueblo<\/a> pic.twitter.com\/n84Mha3tRh<\/a><\/p>\n
