Only a day into the summer season, and a late-evening thunderstorm swept across the Del Rio area bringing over an inch of rainfall in less than an hour, as well as wind gusts of 70 mph at Laughlin AFB and 64 mph at Del Rio International Airport. The National Weather Service issued a Severe Thunderstorm Warning for this storm at 9:18 PM.
Reports of "Green Lightning" were also noted, which is common when hail is present in a storm. While radar indicated some hail presence, only a few reports of small hail were reported via the Del Rio Weather Alerts Facebook Page across the area.
The total precipitation so far for June 2019 in Del Rio (7.78 inches) puts this June as the second-wettest June on record (since 1906), falling behind 1935 when 13.71 inches was recorded.
Severe thunderstorms containing powerful wind gusts are not uncommon during the summer months as high afternoon temperatures prior to a storm help create a lower atmosphere conducive for strong wind plunging down from a thunderstorm's downdraft. This is known as a microburst. This particular storm also contained a distinct bowing shape, indicating powerful wind gust presence, and was well-supported by an upper-tropospheric disturbance aloft, adding to it's severe potential.
