STP 08-28-2015: Monsoon Moisture Fed Isolated-to-Scattered Thunderstorms

Issue Date: Friday, August 28th, 2015
Issue Time: 9:00 AM MDT


Monsoonal moisture continued its push across Colorado in association with a mid-level trough, provided enough fuel for scattered thunderstorms along and over the High Country, with more isolated coverage to the east. Fortunately, the timing of the trough was not favorable for widespread strong thunderstorms. Instead, storms relied mainly on the heat of the day to break the cap, with very marginal instability available. This kept most showers and thunderstorms on the garden-variety side of the scale, with only a couple stronger thunderstorms producing pea-sized hail and brief heavy rain. No flash flooding was reported, but street/field ponding did occur under the strongest thunderstorms.

According to National Weather Service Local Storm Reports, pea-to-dime sized hail was reported 2 miles S of De Beque (Mesa County), and pea-sized hail with heavy rain was reported 2 miles N of Black Forest (El Paso County).
