STP 07-05-2015: Isolated Thunderstorms East of the Divide, Scattered Thunderstorms West

Issue Date: Sunday, July 5th, 2015
Issue Time: 9:00 AM MDT

Summary:

The upper-level ridge flattened out and slid east yesterday, allowing moisture “reinforcements” into western Colorado, which provided the fuel for scattered showers and thunderstorms. Precipitable water values reached above 1 inch and near record levels for the date, so thunderstorms produced rainfall very efficiently. At the current time, scattered showers continue near the CO/UT border.
Most of the activity yesterday was confined to the High Country, but a few isolated storms were able to develop across the Urban Corridor, Palmer Ridge, Northeast Plains, Southeast Plains, and Raton Ridge regions. A couple of those storms became severe.

As far as storm reports are concerned, the following were reported to local NWS offices:

2 miles S of Estes Park (Larimer County): Heavy rain, 0.85 inches/20 minutes
4 miles E of Ault (Weld County): 1.0 inch hail
6 miles E of Stonington (Baca County): Tornado
9 miles N of Campo (Baca County): 1.25 inch hail
7 miles SE of Stonington (Baca County): Pole barn destroyed by thunderstorm winds
4 miles SE of Stonington (Baca County): 2.25 inch hail, 75 mph thunderstorm wind gust
