This year’s June now ranks as the second wettest June in Del Rio history with a current record of 7.78 inches of rainfall.
Friday’s rainfall provided winds at 70 mph at Laughlin Air Force Base and 64 mph at Del Rio International Airport. Lightning was heard throughout the rain and streets became slippery to the public.
The National Weather Service issued a severe thunderstorm warning at 9:18 p.m. on Friday night.
Smalltown Weather Meteorologist Dan Schreiber noted in the past few decades, June has averaged the second-wettest month in Del Rio, with an average rainfall of 2.35 inches – the wettest month being May.
“This year, June has been the wettest month, accounting for 59 percent of the total year’s rainfall in Del Rio,” Schreiber said.
Storms similar to the one on Friday are not uncommon, but a direct impact on Del Rio is somewhat rare, according to Schreiber.
There were reports of “green lightning,” which are common when hail is present in a storm. According to Schreiber, the radar indicated some hail presence and few reports of small hail were made on the Del Rio Weather Alerts Facebook page.
A transformer was struck by lightning heading westbound on Highway 90 during the rain. Local theater, Movies 8 employees dealt with power and movie screenings going out three times throughout the rain.
Previously, this year’s June was tied for the third wettest June in Del Rio history and now falls short of the 1935 June record of 13.71 inches.
“This June has been significantly wetter than normal, and this is largely due to slightly cooler-than-normal temperatures across a large portion of the western United States, with the exception of the Pacific Northwest, and warmer-than-normal temperatures across the Southeast and Southern Atlantic Seaboard, corresponding with El Niño weather pattern,” Schreiber said. According to Schreiber, this atmospheric alignment has allowed springtime storm systems to continue to plunge southward to Central Texas, pick up added moisture from the warm Gulf of Mexico, and cause significant rains over the Del Rio area.
Schreiber added severe thunderstorms containing powerful wind gusts are not uncommon during the summer months as high afternoon temperatures prior to the storm help create a lower atmosphere conducive for strong wind plunging down from the thunderstorm’s downdraft; this is known as a microburst.
Schreiber predicts there will be a decrease in rainfall as July approaches, with an increase later into August and through the early fall season.
