Yesterday saw early morning showers for the Southeast Plains, associated with a frontal boundary extending back into eastern Colorado from a low centered over Nebraska\/South Dakota. These showers cleared out from west to east by mid-morning from daytime heating along with the northeastward progression of the associated low. The Eastern Plains received between 0-1.0” in most places with a few higher totals such as 1.57” in Vernon and 1.2” near Lincoln.<\/p>\n
Further west, late morning daytime heating combined with above normal precipitable water<\/span> from a plume of monsoonal moisture circling the high-pressure ridge to the southeast, which allowed for convection<\/span> to develop across much of the high terrain in the western half of the state. Storms increased in coverage and intensity as the afternoon progressed, and slow steering flow expanded storms onto the Urban Corridor and Palmer Ridge as well. Slow storm motion combined with ample available moisture allowed for very heavy rainfall, especially under embedded convection<\/span>.<\/p>\n By evening, there was widespread<\/span> coverage of showers and thunderstorms across much of the state. Drying generally occurred from west to east, as the high-pressure ridge weakened and moved eastward. Still, showers and thunderstorms lasted well into the overnight hours and early morning for the Southeast Plains, Palmer and Raton Ridge.<\/p>\n The Urban Corridor received the bulk of the rainfall yesterday- Flood Advisories and Severe Thunderstorm<\/span> warnings patchworked the area from north Aurora and southeast Denver all the way to west of Colorado Springs. From Castle Rock up to northwest Aurora received the heaviest precipitation from the storms, with most observations in and around the city between 1-2”, although southwest and northeast of the city received lower amounts generally under 1”. Some of the most significant precipitation totals are listed below:<\/p>\n • 2.91” in Louviers Flooding was significant due to the amount of rainfall that occurred. Below are reports of street flooding in Southeast Denver and nearby areas:<\/p>\n • South Chambers Road in Aurora was impassable due to flooding This was flash flooding<\/span> at I-25 and Arapahoe Rd (CO 88) around 3:30pm today. @NWSBoulder<\/a> #cowx<\/a> #flooding<\/a> pic.twitter.com\/d4Y64lIeqK<\/a><\/p>\n — Kyle Witter (@kyle_witter) August 16, 2022<\/a><\/p><\/blockquote>\n
