STP 06-26-2017: Scattered T’Storms With Heavy Rainfall Across Southeast

Issue Date: Monday, June 26th, 2017
Issue Time: 9:50AM MDT

Summary:

An accurate word to describe Sunday’s weather across our state is “persistent”. With a weak upper-level ridge centered west of Colorado, subsidence and generally clear skies continued to be the rule west of the Continental Divide.

Of course, the devil is always in the details. To the east, despite a persistent atmosphere aloft, slow and steady moisture return increased low level moisture and provided more fuel (compared to Saturday) for isolated to scattered thunderstorms. The focal points, and highest storm coverage, were off the south face of the Palmer Ridge and the Raton Ridge, especially the Wet Mountains. Several rounds of storms were observed, mainly limited to the foothills. Generally, rainfall was not overly impressive with 0.5 to 0.75 inches common under the storm cores. However, the exception was an isolated, severe storm in Baca County where a Local Storm Report noted 1.5 inches of rain in 10 minutes (!), a roughly 1 in 100 year event. In addition, the storm dropped copious amounts of small hail and prompted a tornado warning as soon as it crossed into New Mexico. A few other storms farther west produced over 1 inch of rain across large swaths of Las Animas and Huerfano counties. Although storms fell mainly over ungauged areas, the USGS gauge on the Purgatoire River near Thatcher (Las Animas County) showed an impressive spike (see below).

As of this morning, flooding was fortunately not reported from Sunday’s rains. For rainfall estimates in your area, check out the State Precipitation Map below.
