Summary:
Storms began to fire over the mountains yesterday afternoon just after 11AM. Moisture was confined to the southern portion of the state and favored the higher terrain. The Southeast Mountains and Front Range had the highest totals, although there was also heavy rainfall over the San Juan Mountains and Southwest Slope. Isolated storms drifted into the southern Urban Corridor and southern Southeast Plains in the early evening hours. All showers and thunderstorms dissipated shortly after sundown and ceased by 10:30PM.
Over the mountains, the slow moving storms prompted a handful of Areal Flood Advisories for their local, heavy rainfall. The Wolf Creek Summit SNOTEL site in the Rio Grande National Forest reported 1.5 inches of rain over the course of the day, with the majority falling in a 2 hour window just after noon. The Apishapa SNOTEL site in the Southeast Mountains had 1.4 inches of rain the last 24-hours with the majority falling just after noon as well. In Las Animas County near the Spanish Peaks, 1.47 inches of heavy rainfall was reported to the NWS Pueblo office. Total storm rainfall estimates were as high as 1.8 inches over the southern mountains. There was one Flash Flood Warning issued for an isolated thunderstorm near southern Colorado Springs/Fort Carson. A USGS gauge at Fort Carson recorded 1.45 inches in 1 hour. Radar estimated totals for this storm were 2.5 inches with 1 hour rain rates as high as 1.5 inches. There were no flood reports as of Sunday morning.
