A potent storm system moved across portions of Texas during the early morning hours of April 13th, 2019. While severe weather was rather isolated, it did manage to produce large hail near Barnhart and Big Lake, Texas and in Brackettville, Texas - and also triggered tornado warnings in both places.
A Tornado Watch had previously been issued by the National Weather Service during the very early morning hours. Severe Thunderstorm Warnings, Tornado Warnings, and some areas of Flash Flooding also occurred across the West Texas region.
A severe thunderstorm was noted crossing from the Mexican state of Coahuila into Kinney County, Texas around 3:45 AM. This storm quickly intensified along Pinto Creek in rural Kinney County and produced radar signatures indicative of a potential tornado as it neared Brackettville. While reports of a tornado touchdown have not been received, severe reports of golf ball to half-dollar sized hail were submitted, as well as reports of shattered windshields. The storm then continues eastbound, prompting additional tornado warnings for the northern portion of Uvalde, Texas around 6:45 AM, then Sabinal, Texas around 8:00 AM.
Around sunrise, an additional line of storms swept through Del Rio bringing gusty winds (nearly 50 MPH) and briefly heavy rainfall (0.23 inches at Del Rio Airport and 0.26 inches at Laughlin AFB). Additionally, Laughlin AFB reported 1/2 inch hail. A report of pea to nickle-sized hail also surfaced in the San Felipe neighborhood of Del Rio.
