Monsoon<\/span> moisture moved through the southern portion of the state yesterday. Showers began yesterday morning over the San Juan Mountains. The rain throughout the day accumulated to just over 1 inch. As this plume moved over E\/NE, it encountered a fairly stable<\/span> air. Cloud cover was not able to break up as much, which limited instability. However, this disturbance was strong enough to create widespread<\/span> showers with some stronger embedded convection<\/span>. One thunderstorm triggered Flash Flood<\/span> Warning<\/span> over the Junkins burn scar, but fortunately, no flooding was reported. As storms moved off the higher terrain they quickly dissipated in strength. The widespread<\/span> showers were able to increase the flow enough at the USGS La Junta gage on the Arkansas River that it reached Action stage. Please stay tuned to the daily Flood Threat Bulletin for the latest information on the Arkansas River. Radar storm total estimates over this area were as high as 2.2 inches with a SNOTEL station recording 0.9 inches near the southern Southeast Mountains.<\/p>\n More storms were able to fire over the Cheyenne Ridge later in the evening that moved through the northeast corner of the state. While initially these storms had a Severe Thunderstorm<\/span> Warning<\/span>, they quickly began to weaken with the lack of instability. This was not before the storms quickly dropped 2.12 inches over Grover, CO in Weld County. Within this line of storms, radar estimates were highest in Yuma County where 2.9 inches fell in about one hour.<\/p>\n
