STP 08-09-2016: Mainly Quiet West of the Divide, a Few Stronger Storms East

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

Summary:

Drier air invaded from the west as the upper-level trough continued to dig across the western US, which helped to shut down most activity yesterday west of the Continental Divide. A few thunderstorms over San Miguel and Montrose counties took exception to this dry air, producing small hail (mainly pea-sized) and brief periods of light-to-moderate rainfall. Elsewhere, mostly sunny skies were the result of the overall atmospheric setup with only a couple isolated showers over the higher terrain.

East of the Divide, a few stronger thunderstorms rumbled, producing periods of heavy rain and hail, with one severe hail report of 1.0 inch hail from 9 miles W of Peetz (Logan County). Heavy rain reports are as follows:

1.75 inches of heavy rain: 8 miles NE of Spanish Peaks (Huerfano County)
1.18 inches of heavy rain: 4 miles S of Spanish Peaks (Las Animas County)

No flash flooding was reported, but street/field ponding likely occurred underneath stronger thunderstorms. A small stream, associated with the first listed heavy rain report above, was reported to be running about 10x larger than normal.
