Episode narrativeepisode_narrativeAn upper level disturbance, sandwiched between a receding upper level ridge across the southwest U.S. and another ridge across Florida and the eastern Gulf of Mexico, drew deep tropical moisture northward from the Bay of Campeche and points south. Meanwhile, a vigorous upper level disturbance across the upper midwest and associated frontal zone extending from the Great Lakes southwest into North Texas helped trigger a thunderstorm complex, which initially surge into the South Texas Plains overnight on the 21st. The complex set off boundaries which sparked intense storms along the Rio Grande and into northwest Tamaulipas and northern Nuevo Leon, M��xico, a little after daybreak on the 22nd. By early afternoon, the combination of the disturbance, daytime heating, advancing outflow from previous storms focused on the Lower Rio Grande Valley. Intense, slow moving thunderstorms formed from Mercedes/Weslaco northeast into Santa Rosa, Harlingen, and Raymondville. The storms would gradually weaken as they edged toward Brownsville. ||On the 23rd, the surface low parked across Cameron County. Old boundaries, a pesky upper disturbance, and some heating into very unstable air triggered another round of tropical torrents from late morning through late afternoon. These rains inundated parts of the Lower Valley with 2 to 4 more inches of rain ��� some which fell in the same spots on the 22nd. ||Two day rainfall totals ranged generally from 3 to 6 inches across the Lower Valley, with peak values in a swath bounded by Weslaco/Progresso northeast to Raymondville, then southeast to Brownsville. Numerous instances of nuisance flooding, worse in areas where drainage was poor or debris had not been cleared from ditches or canals, were reported through the period.
Event narrativeevent_narrativeSlow moving thunderstorms, containing up to an hour and a half of torrential rains, dumped between 3 and 4 inches across the heart of populated Hidalgo County, from Mission to Weslaco, during the early and mid afternoon of June 22nd. Numerous instances of nuisance urban flooding were reported, much in the typical poor drainage locations that see flooding with any locally heavy rainfall.||Nuisance flooding of roads and ditches were reported in the typical poor drainage locations of McAllen/Pharr and Weslaco. At McAllen/Miller airport, 3.13 inches of rain fell in less than two hours before the power was knocked out due to lightning in the area. CoCoRaHS observers reported 3.08 inches and 3.18 inches in Mission and Edinburg, respectively, and nearly 3 inches (2.84) fell at the Mid Valley Airport in Weslaco.
