STP 08-17-2016: Uptick in Coverage/Intensity of Showers and Thunderstorms

Issue Date: Wednesday, August 17th, 2016
Issue Time: 9:00 AM MDT

Summary:

Better mid-level moisture was transported into the state yesterday, raising IPW values to above 0.75 inches for much of the state. This increase in moisture, combined with the passage of a mid-level disturbance, provided support for greater coverage/intensity of showers/storms as compared to Monday. Most of the moisture existed between 2.5 and 3.5 km above ground level, which cut down on effective rain rates at the surface for most locations. However, as is typical of Colorado’s atmosphere, one region outperformed the rest thanks to slow-moving storms and their ability to moisten the lower-levels. While no flash flooding has been reported, street/field ponding likely occurred across portions of El Paso and Pueblo counties, thanks in part to small hail creating drainage issues as heavy rain fell. The following heavy rain observations were reported:

1.75 inches: 9 miles WSW of Fountain (El Paso), 6 miles NNE of Colorado Springs (El Paso)
1.50 inches (in 50 minutes): 3 miles NNE of Schriever AFB (El Paso)
1.49 inches: 6 miles SE of the Air Force Academy (El Paso)
1.07 inches: 6 miles SSE of the Air Force Academy (El Paso)
0.99 inches: 6 miles NW of Peterson AFB (El Paso)
0.97 inches: 4 miles NE of Blende (Pueblo)
