Intense heating, coupled with a weak passing mid-level disturbance and sufficient moisture and instability, fueled an active round of weather Thursday afternoon and evening (4 June). Temperatures climbing to near and above the triple digit mark provided enough energy to cause widely scattered thunderstorms to develop across the Texas Panhandle Thursday afternoon. |
|
High temperatures measured by the West Texas Mesonet on Thursday, 4 June 2020. | |
The hot and well mixed lower atmosphere and high-based nature of the thunderstorms provided ideal conditions for the generation of strong and severe wind gusts, though pockets of hail also occurred with the most intense storms. A wind gust of 72 mph was measured from one storm near Silverton, while a 60 mph gust was recorded at Caprock Canyon State Park. | |
Regional radar animation valid from 4:48 pm to 5:58 pm on 4 June 2020. Additional regional radar animations can be found at: 2:48 pm to 3:58 pm; 5:48 pm to 6:58 pm; 7:48 pm to 8:58 pm; and 8:18 pm to 9:28 pm. | |
The thunderstorm activity developed and tracked south and southeast through the evening. Accumulating dime size hail fell just east of Plainview, while golf ball size hail was observed west of Floydada, north of Lorenzo and in Ralls. This same storm produced 2 inch diameter hail near the small community of Allmon, southwest of Floydada, while also generating damaging winds that downed multiple power poles, blew over a tractor trailer and flipped a center pivot near Ralls. | |

The thunderstorms formed into a small cluster as they raced southward across the southeast South Plains and far western Rolling Plains through the late evening hours. Wind gusts in excess of 70 mph accompanied this activity, with a gust as high as 94 mph measured in southwest Garza County, along the edge of the Caprock. | |
Peak thunderstorm wind gusts (mph) measured by the West Texas Mesonet and NWS Thursday evening (4 June 2020). | |
Unfortunately, the powerful winds caused significant damage in and around Post, including flattening outbuildings, lofting carports, damaging roofs, flipping a semi and downing transmission poles. | |
Meteogram from the Macy Ranch West Texas Mesonet on Thursday (4 June 2020). | |
The above graphs show how various meteorological variable responded as the extreme winds moved through the Macy Ranch West Texas Mesonet site. The temperature plummeted from the upper 80s to near 60 degrees in a matter of minutes. The strongest winds occurred in advance of the rainfall, though a period of heavy rain and relatively high pressure did immediately follow the worst of the wind. | |

Although the severe outflow winds were the most significant impact at most spots, the thunderstorms did also produce swaths of heavy rain. The heaviest rain, from 1 to 2+ inches, fell in a narrow band from west of Tulia to near Plainview, Ralls and Post. The torrential rain did damage FM 207 north of Post, resulting in its temporary closure. Runoff also poured into Lake Alan Henry, ensuring it remained full, almost 2 feet above conservation level. Officially, Lubbock record 0.69 inches, boosting the yearly total to 6.02 inches. |
