Rain totals of a half inch to an inch were common along and north of a Dimmitt to Floydada to Guthrie line, with localized totals in excess of 2 inches. The rainfall measured by the West Texas Mesonet (WTM) over this period can be VIEWED HERE. A couple of these storms were on the strong side, but the main theme from this activity was widespread welcome rainfall.ĥ-day radar-estimated and bias-corrected rainfall ending at 7 am on Friday (28 April). More widespread showers and thunderstorms developed and moved across the southern Texas Panhandle, northern South Plains and much of the Rolling Plains late Tuesday night into Wednesday morning as the main lift from the upper level storm system moved over. A regional radar animation, valid from 3:35 pm on April 25th to 6:05 am on April 27th, can be VIEWED HERE. Lubbock WSR-88D radar animation valid from 1:32 am to 6:02 am Thursday morning (26 April 2023). Thus, the tornado was assigned an EF-Unknown rating. A National Weather Service (NWS) Survey Team the following day could not find any signs of damage from the short-lived tornado. In addition to generating very large hail and damaging winds, the Tuesday evening supercell produced one brief tornado near Dougherty, in a rural area of southeastern Floyd County. The pictures were taken the following day by the NWS Lubbock Damage Survey Team. The severe winds swept through the town, destroying an old, abandoned grocery store (shown below), while causing considerable roof damage to several other structures.Ī building in McAdoo that was destroyed by a severe thunderstorm Wednesday evening (25 April 2023). The McAdoo West Texas Mesonet (WTM), located 3 miles north-northwest of the community, measured a peak gust of 90 mph at 9:39 pm. The hail-producing thunderstorm occasionally generated intense straight-line winds too. The picture was taken the following day by the NWS Lubbock Damage Survey Team. Hail damage sustained to vehicles in Dickens on Wednesday evening (25 April 2023).

Windows were smashed out of homes and vehicles, while roofs and siding incurred large impact craters. The large to giant hail caused significant damage around the region, including Dickens, which took a direct hit. "RGB-True Color" satellite animation valid from 3:06 pm to 7:26 pm on Wednesday (25 April 2023). During its 6+ hour trek, the thunderstorm was a proficient hail producer, tossing hail as large as baseballs, softballs and even grapefruit. The southeast track of the supercell brought the thunderstorm across Tulia, just northeast of Floydada, and eventually through McAdoo and Dickens before finally weakening over far southeast Dickens County late Tuesday evening. The pictures were relayed by Jacob Riley and are courtesy of Alana Pollard and Dolores Nix, respectively. Large hail that fell in Dickens (left) and Tulia (right) on Wednesday evening (25 April). Once the storm became organized and started rotating, it "turned to the right," which means that it moved more southeastward (and opposed to eastward). The most intense storm of the day evolved from a cluster of thunderstorms over the southwestern Texas Panhandle during the late afternoon hours.
Lubbock WSR-88D radar animation valid from 5:52 pm to 9:57 pm on Wednesday (25 April). Although moisture levels and instability were not particularly high by late April standards, they were sufficient, when coupled with improving vertical wind shear, to support organized thunderstorms, including rotating (supercell) storms. The initial thunderstorm development was concentrated across the southwestern Texas Panhandle as well as the western South Plains, in close proximity to the warm front and dryline, respectively. Water vapor satellite animation valid from 6:21 am to 7:26 am on Wednesday (26 April 2023). The approach of an upper level storm system through the Four Corners, in combination with a gradual return of Gulf of Mexico moisture, teamed with a tightening dryline and lifting warm front to trigger scattered thunderstorms Tuesday afternoon and evening (25 April 2023).
